2. Safety & Maintenance Instructions, Warnings, and Notes

Index of this chapter:1. Safety Instructions for Repairs2. Maintenance Instructions3. Warnings4. Notes

2.1 Safety Instructions for Repairs

Safety regulations require that during a repair:• Due to the 'hot' parts of this chassis, the set must be

connected to the AC power via an isolation transformer.• Safety components, indicated by the symbol , should be

replaced by components identical to the original ones.• When replacing the CRT, safety goggles must be worn. Safety regulations require that after a repair, the set must be returned in its original condition. Pay particular attention to the following points:• General repair instruction: as a strict precaution, we advise

you to resolder the solder connections through which the horizontal deflection current is flowing, in particular:– all pins of the line output transformer (LOT)– fly-back capacitor(s)– S-correction capacitor(s)– line output transistor– pins of the connector with wires to the deflection coil– other components through which the deflection current

flows.Note: This resoldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years old.• Route the wire trees and EHT cable correctly and secure

them with the mounted cable clamps.• Check the insulation of the AC power cord for external

damage.• Check the strain relief of the AC power cord for proper

function, to prevent the cord from touching the CRT, hot components, or heat sinks.

• Check the electrical DC resistance between the AC plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:1. Unplug the AC power cord and connect a wire between

the two pins of the AC plug.2. Turn on the main power switch (keep the AC power

cord unplugged!).3. Measure the resistance value between the pins of the

AC plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MOhm and 12 MOhm.

4. Switch the TV 'off' and remove the wire between the two pins of the AC plug.

• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.

2.2 Maintenance Instructions

It is recommended to have a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions:• When the set is used under normal circumstances, for

example in a living room, the recommended interval is three to five years.

• When the set is used in an environment with higher dust, grease or moisture levels, for example in a kitchen, the recommended interval is one year.

• The maintenance inspection includes the following actions:1. Perform the 'general repair instruction' noted above.2. Clean the power supply and deflection circuitry on the

chassis.

3. Clean the picture tube panel and the neck of the picture tube.

2.3 Warnings

• In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in Fig. 2-1, to discharge the picture tube. Use a high voltage probe and a multi-meter (position Vdc). Discharge until the meter reading is 0 V (after approx. 30 s).

Figure 2-1 Discharge picture tube

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this potential.

• Available ESD protection equipment:– Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable, and ground cable) 4822 310 10671.

– Wristband tester 4822 344 13999.• Together with the deflection unit and any multi-pole unit,

flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. Adjustment of this unit during repair is therefore not recommended.

• Be careful during measurements in the high voltage section and on the picture tube.

• Never replace modules or other components while the unit is switched 'on'.

• When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

2.4 Notes

2.4.1 General

• Measure the voltages and waveforms with regard to the chassis (= tuner) ground (), or hot ground (), depending on the area of circuitry being tested.

• The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode (see “Service Modes, Error Codes, and Faultfinding” section) with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 61.25 MHz (NTSC, channel 3).

• Where necessary, measure the waveforms and voltages with () and without () aerial signal. Measure the voltages in the power supply section both in normal operation () and in standby (). These values are indicated by means of the appropriate symbols.

V

CL96532156_040.eps140501

Safety & Maintenance Instructions, Warnings, and Notes EN 5L01.1L AC 2.

• The picture tube panel has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating.

• The semiconductors indicated in the circuit diagram and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

2.4.2 Schematic Notes

• All Resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kOhm).

• Resistor values with no multiplier may be indicated with either an 'E' or an 'R' (e.g. 220E or 220R indicates 220 Ohm).

• All Capacitor values are expressed in Micro-Farads (µ = x10-6), Nano-Farads (n = x10-9), or Pico-Farads(p = x10-12).

• Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).

• An 'asterisk' (*) indicates component usage varies. Refer to the diversity tables for the correct values.

• The correct component values are listed in the Electrical Replacement Parts List. Therefore, always check this list when there is any doubt.

2.4.3 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

• Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions - reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

• Before powering up the TV set with the back cover off (or on a test fixture), attach a clip lead to the CRT DAG ground and to a screwdriver blade that has a well insulated handle. After the TV is powered on and high voltage has developed, probe the anode lead with the blade, starting at the case of the High Voltage Transformer (flyback - IFT). Move the blade to within two inches of the connector of the CRT. If there is an arc, you found it the easy way, without getting a shock! If there is an arc to the screwdriver blade, replace the part which is causing the problem; the High Voltage Transformer or the lead (if it is removable).

5.1 Test Points

The chassis is equipped with test points printed on the circuit board assemblies. These test points refer to the functional blocks:

Table 5-1 Test Point Overview

The numbering is in a logical sequence for diagnostics. Always start diagnosing within a functional block in the sequence of the relevant test points for that block. Perform measurements under the following conditions:• Service Default Alignment Mode.• Video: color bar signal.• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

Service Default Alignment Mode (SDAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between dealer and customer.There is also the option of using ComPair, a hardware interface between a computer (see requirements) and the TV chassis. It offers the ability of structured trouble shooting, error code reading and software version readout for all chassis. Requirements: To run ComPair on a computer (laptop or desktop) requires, as a minimum, a 486 processor, Windows 3.1 and a CD-ROM drive. A Pentium Processor and Windows 95/98 are however preferred (see also paragraph 5.4).

5.4 ComPair

5.4.1 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products. ComPair is a further development on the European DST (service remote control), which allows faster and more accurate diagnostics. ComPair has three big advantages:

• ComPair helps you to quickly get an understanding on how to repair the chassis in a short time by guiding you systematically through the repair procedures.

• ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C commands yourself because ComPair takes care of this.

• ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away.

5.4.2 Specifications

ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. In case of the L01 chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector (located on the Main panel, see also figure 8-1 suffix D). The ComPair faultfinding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in two ways:• Automatic (by communication with the television):

ComPair can automatically read out the contents of the entire error buffer. Diagnosis is done on I2C level. ComPair can access the I2C bus of the television. ComPair can send and receive I2C commands to the micro controller of the television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set.

• Manually (by asking questions to you): Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extends. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the screen give a picture? Click on the correct answer: YES / NO) and showing you examples (e.g. Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope). You can answer by clicking on a link (e.g. text or a waveform picture) that will bring you to the next step in the faultfinding process.

By a combination of automatic diagnostics and an interactive question / answer procedure, ComPair will enable you to find most problems in a fast and effective way. Beside fault finding, ComPair provides some additional features like:• Up- or downloading of pre-sets.• Managing of pre-set lists.• Emulation of the Dealer Service Tool (DST).• If both ComPair and SearchMan (Electronic Service

Manual) are installed, all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink. Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Mono-carrier. – Click on the 'Panel' hyperlink to automatically show the

PWB with a highlighted capacitor C2568. – Click on the 'Schematic' hyperlink to automatically

show the position of the highlighted capacitor.

5.4.3 How To Connect ComPair

1. First install the ComPair Browser software (see the Quick Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with “PC”) of the ComPair interface.

Service Modes, Error Codes, and Fault Finding EN 23L01.1L AC 5.

3. Connect the AC power adapter to the supply connector (marked with “POWER 9V DC”) on the ComPair interface.

4. Switch the ComPair interface OFF.5. Switch the television set OFF (remove the AC power).6. Connect the ComPair interface cable between the

connector on the rear side of the ComPair interface (marked with “I2C”) and the ComPair connector on the mono carrier (see figure 8-1 suffix D).

7. Plug the AC power adapter in the AC power outlet and switch on the interface. The green and red LEDs light up together. The red LED extinguishes after approx. 1 second while the green LED remains lit.

8. Start the ComPair program and read the “introduction” chapter.

5.4.5 Error Buffer

The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is written at the left side and all other errors shift one position to the right.

5.4.6 How To Read The Error Buffer

You can read the error buffer in 3 ways:• On screen via the SDAM (only if you have a picture).

Examples:– ERROR: 0 0 0 0 0: No errors detected– ERROR: 6 0 0 0 0: Error code 6 is the last and only

detected error– ERROR: 9 6 0 0 0: Error code 6 was first detected and

error code 9 is the last detected (newest) error• Via the blinking LED procedure (when you have no

picture). See next paragraph.• Via ComPair.

5.4.7 How To Clear The Error Buffer

The error code buffer is cleared in the following cases:• By activation of the CLEAR command in the SDAM menu:• If the content of the error buffer has not changed for 50

hours, it resets automatically.

Note:When leaving SDAM by disconnecting the set from AC power, the error buffer is not reset.

5.4.8 Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. These to ensure that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations an error code is only the result of another error code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection).

Table 5-3 Error Code Table

5.5 The Blinking LED Procedure

Via this procedure you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture. When the SDAM is entered, the LED will blink the contents of the error-buffer. • n short blinks (n = 1 - 14),• When all the error-codes are displayed, the sequence

finishes with a LED blink of 3 s,• The sequence starts again. Example of error buffer: 12 9 6 0 0 After entering SDAM: • 12 short blinks followed by a pause of 3 s,• 9 short blinks followed by a pause of 3 s,

5.6 Protections

If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. In some error cases the microprocessor does not put the set in the protection mode. The error codes of the error buffer can be read via the service menu (SDAM), the blinking LED procedure or via ComPair. To get a quick diagnosis the chassis has two service modes implemented:• The Customer Service Mode (CSM).• The Service Default Alignment Mode (SDAM). Start-up of

the set in a predefined way and adjustment of the set via a menu and with the help of test patterns.

5.7 Repair Tips

Below some failure symptoms are given, followed by a repair tip.• Set is dead and makes hiccupping sound. “MainSupply”

is available. Hiccupping stops when de-soldering L5561, meaning that problem is in the “MainSupply” line. No output voltages at LOT, no horizontal deflection. Reason: line transistor 7460 is defective.

• Set is dead, and makes no sound. Check power supply IC 7520. Result: voltage at pins 1, 3, 4, 5 and 6 are about 180 V and pin 8 is 0 V. The reason why the voltage on these pins is so high is because the output driver (pin 6) has an open load. That is why MOSFET 7521 is not able to switch. Reason: feedback resistor 3523 is defective. Caution: be careful measuring on the gate of 7521; circuitry is very high ohmic and can easily be damaged!

• Set is in hiccup mode and shuts down after 8 s. Blinking LED (set in SDM mode) indicates error 5. As it is unlikely that the “POR” and “+8V protection” happen at the same time, measure the “+8V”. If this voltage is missing, check transistor 7480.

• Set is non-stop in hiccup mode. Set is in over current mode; check the secondary sensing (opto coupler 7515) and the “MainSupply” voltage. Signal “Stdby_con” must be logic low under normal operation conditions and goes to high (3.3 V) under standby and fault conditions.

• Set turns on, but without picture and sound. The screen shows snow, but OSD and other menus are okay. Blinking LED procedure indicates error 11, so problem is expected in the tuner (pos. 1000). Check presence of supply voltages. As “Vlotaux+5V” at pin 5 and 7 are okay, “VT_supply” at pin 9 is missing. Conclusion: resistor 3460 is defective.

• Set turns on, but with a half screen at the bottom. Sound is okay. Blinking LED (set in SDM mode) indicates error 3. Check “Vlotaux+11V” and “+50V”. If they are okay, problem is expected in the vertical amplifier IC 7471. Measure with a scope the waveform on pin 17 of the UOC. Measure also at pin 1 of IC 7471. If here the signal is missing, a defective resistor R3244 causes the problem

Alignments EN 65L01.1L AC 8.

8. Alignments

Index of this chapter:1. General Alignment Conditions2. Hardware Alignments3. Software Alignments and Settings

Note: The Service Default Alignment Mode (SDAM) was described in chapter 5. Menu navigation is done with the 'CURSOR UP, DOWN, LEFT or RIGHT' keys of the remote control transmitter.

8.1 General Alignment Conditions

Perform all electrical adjustments under the following conditions:• AC voltage and frequency: 110 V (± 10 %), 60 Hz (± 5 %).• Connect the set to the AC power via an isolation

transformer.• Allow the set to warm up for approximately 20 minutes.• Measure the voltages and waveforms in relation to chassis

ground (with the exception of the voltages on the primary side of the power supply). Never use the cooling fins / plates as ground.

• Test probe: Ri > 10 MΩ; Ci < 2.5 pF.• Use an isolated trimmer / screwdriver to perform the

alignments.

8.2 Hardware Alignments

Figure 8-1 Family Board (top view)

8.2.1 Vg2 Adjustment

1. Activate the SDAM.2. Go to the WHITE TONE sub menu.3. Set the values of NORMAL RED, GREEN and BLUE to 40.4. Go, via the MENU key, to the normal user menu and set

– CONTRAST to zero.– BRIGHTNESS to minimum (OSD just visible in a dark

room).5. Return to the SDAM via the MENU key.

6. Connect the RF output of a pattern generator to the antenna input. Test pattern is a 'black' picture (blank screen on CRT without any OSD info).

7. Set the channel of the oscilloscope to 50 V/div and the time base to 0.2 ms (external triggering on the vertical pulse).

8. Ground the scope at the CRT panel and connect a 10:1 probe to one of the cathodes of the picture tube socket (see diagram B).

9. Measure the cut off pulse during first full line after the frame blanking (see Fig. 8-2). You will see two pulses, one being the cut off pulse and the other being the white drive pulse. Choose the one with the lowest value, this is the cut off pulse.

10. Select the cathode with the highest Vdc value for the alignment. Adjust the Vcutoff of this gun with the SCREEN potentiometer (see Fig. 8-1) on the LOT to the correct value (see table below).

11. Restore BRIGHTNESS and CONTRAST to normal (= 31).

Figure 8-2 Vcutoff

Table 8-1 Vg2 cut-off point (large screen)

8.2.2 Focusing

1. Tune the set to a circle or crosshatch test pattern (use an external video pattern generator).

2. Choose picture mode NATURAL (or MOVIES) with the ‘SMART PICTURE’ button on the remote control transmitter.

3. Adjust the FOCUS potentiometer (see Fig. 8-1) until the vertical lines at 2/3 from east and west, at the height of the centerline, are of minimum width without visible haze.

8.3 Software Alignments and Settings

Enter the Service Default Alignment Mode (see chapter 5). The SDAM menu will now appear on the screen.Select one of the following alignments:1. OPTIONS2. TUNER3. WHITE TONE4. GEOMETRY5. AUDIO

8.3.1 Options

Figure 8-3 Options menu

Options are used to control the presence / absence of certain features and hardware.

How to change an Option ByteAn Option Byte represents a number of different options. Changing these bytes directly makes it possible to set all options very fast. All options are controlled via seven option bytes. Select the option byte (OP1.. OP7) with the MENU UP/DOWN keys, and enter the new value. Leaving the OPTION submenu saves changes in the Option Byte settings. Some changes will only take effect after the set has been switched OFF and ON with the AC power switch (cold start).

How to calculate the value of an Option ByteCalculate an Option Byte value (OB1 .. OB7) in the following way:Check the status of the single option bits (OP): are they enabled (1) or disabled (0).When an option bit is enabled (1) it represents a certain value (see column ‘Dec. value’ in table below). When an option bit is disabled, its value is 0.The total value of an Option Byte is formed by the sum of its eight option bits.

Index of this chapter:1. Introduction2. Audio Signal Processing3. Video Signal Processing4. Synchronization5. Deflection6. Power Supply7. Control8. Abbreviations9. IC Data Sheets Notes: • For a good understanding of the following circuit

descriptions, please use the block diagram in section 'Wiring Diagram, Block Diagrams, and Overviews' and/or the electrical diagrams in section 'Circuit Diagrams and PWB Layouts'. Where necessary, you will find a separate drawing for clarification.

• Figures below can deviate slightly from the actual situation, due to different set executions.

9.1 Introduction

The 'L01.1L AC' chassis is a global TV chassis for the model year 2003 and is used for TV sets with screen sizes from 20" to 36", in Super Flat, Real Flat, and Wide Screen executions. In comparison to its predecessor (the 'L01.1L AB'), the chassis has enhanced features like 'Virtual Dolby', 'Sub Woofer out', and 'Active Control'. The standard architecture consists of a Main panel, a Picture Tube panel, a Side I/O panel, and a Top Control panel.The Main panel consists primarily of conventional components with hardly any surface mounted devices.

Figure 9-1 Block diagram

The functions for video processing, microprocessor (uP), and teletext (TXT) decoder are combined in one IC (TDA958xH), the so-called Ultimate One Chip (UOC). This chip is (surface) mounted on the copper side of the LSP. The 'L01.1L AC' is divided into 2 basic audio systems, i.e. mono and stereo sound. While the audio processing for the mono sound is done in the audio block of the UOC, an external audio processing IC is used for stereo sets.

The tuning system features 181 channels with on-screen display. The main tuning system uses a tuner, a microcomputer, and a memory IC mounted on the main panel. The microcomputer communicates with the memory IC, the customer keyboard, remote receiver, tuner, signal processor IC and the audio output IC via the I2C bus. The memory IC retains the settings for favorite stations, customer-preferred settings, and service / factory data. The on-screen graphics and closed caption decoding are done within the microprocessor, and then sent to the signal processor IC to be added to the main signal. The chassis utilizes a Switching Mode Power Supply (SMPS) for the main voltage source. The chassis has a 'hot' ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis.

9.2 Audio Signal Processing

9.2.1 Stereo

In stereo sets, the signal goes via the SAW filter (position 1002/1003), to the audio demodulator part of the UOC IC 7200. The audio output on pin 33 goes to the stereo decoder 7831/ 7861. The switch inside this IC selects either the internal decoder or an external source (see also ‘block diagram’). There are two stereo decoder versions used:1. A BTSC Stereo/SAP decoder (MSP34X5 at position 7831)

for the highest specified sets, and 2. A BTSC non-dbx stereo decoder (TDA9853 at position

7861) for BTSC Economic. The built-in stereo decoder can receive both TV stereo and Separate Audio Program (SAP) telecasts where available. A dbx noise reduction system helps provide clear, crisp sound with proper stereo separation. The output is fed to the to the audio amplifier (AN7522 at position 7901). The volume level is controlled at this IC (pin 9) by a 'Volume|Mute' control line from the microprocessor. The audio signal from 7901 is then send to the speaker and headphone output panel.

9.2.2 Mono

In mono sets, the signal goes via the SAW filter (position 1002/1003), to the audio demodulator part of the UOC IC 7200. The audio output on pin 48 goes to the audio amplifier (AN7523 at position 7902). The volume level is controlled at this IC (pin 9) by a 'Volume|Mute' control line from the microprocessor. The audio signal from IC 7902 is then send to the speaker and headphone output panel.

9.3 Video Signal Processing

9.3.1 Introduction

The video signal-processing path consists of the following parts:• RF signal processing.• Video source selection.• Comb filter.• Video demodulation.• Luminance / Chrominance signal processing.• RGB control.• RGB amplifier The processing circuits listed above are all integrated in the UOC TV processor. The surrounding components are for the adaptation of the selected application. The I2C bus is for defining and controlling the signals.

9.3.2 RF Signal Processing

The incoming RF signal goes to the tuner (pos. 1000), where the 45.75 MHz IF signal is developed and amplified. The IF signals then exits the tuner from pin 11 to pass through the SAW filter (pos. 1002/1003). The shaped signal is then applied to the IF processor part of the UOC (pos. 7200). Tuner AGC (Automatic Gain Control) will reduce the tuner gain and thus the tuner output voltage when receiving strong RF signals. Adjust the AGC takeover point via the Service Default Alignment Mode (SDAM). The tuner AGC starts working when the video-IF input reaches a certain input level and will adjust this level via the I2C bus. The tuner AGC signal goes to the tuner (pin 1) via the open collector output (pin 22) of the UOC.The IC also generates an Automatic Frequency Control (AFC) signal that goes to the tuning system via the I2C bus, to provide frequency correction when needed. The demodulated composite video signal is available at pin 38 and then buffered by transistor 7201.

9.3.3 Video Source Selection

The Composite Video Blanking Signal (CVBS) from buffer 7201 goes to the audio carrier trap filters 1200, 1201, or 1202 (depending on the system used), to remove the audio signal. The signal then goes to pin 40 of IC 7200. The internal input switch selects the following input signals:• Pin 40: terrestrial CVBS input• Pin 42: external AV1 CVBS input• Pin 44: external Side I/O CVBS or AV2 (or comb filter)

luminance (Y) input• Pin 45: external AV2 (or comb filter) chrominance (C) input

Figure 9-3 Video source selection

Once the signal source is selected, a chroma filter calibration is performed. The received color burst sub-carrier frequency is used for this. Correspondingly, the chroma band pass filter for PAL/NTSC processing or the cloche filter for SECAM processing is switched on. The selected luminance (Y) signal is supplied to the horizontal and vertical synchronization circuit and to the luminance processing circuit. In the luminance-processing block, the luminance signal goes to the chroma trap filter. This trap is switched 'on' or 'off' depending on the color burst detection of the chroma calibration circuit.The group delay correction part can be switched between the BG and a flat group delay characteristic. This has the advantage that in multi-standard receivers no compromise has to be made for the choice of the SAW filter.

9.3.4 Video Demodulation

The color decoder circuit detects whether the signal is a PAL, NTSC, or SECAM signal. The result is made known to the auto system manager. The PAL/NTSC decoder has an internal clock generator, which is stabilized to the required frequency by using the 12 MHz clock signal from the reference oscillator of the microcontroller / teletext decoder.The base-band delay line is used to obtain a good suppression of cross color effects.The Y signal and the delay line outputs U and V are applied to the luminance / chroma signal processing part of the TV processor.

9.3.5 Luminance / Chrominance signal Processing

The output of the YUV separator is fed to the internal YUV switch, which switches between the output of the YUV separator or the external YUV (for DVD or PIP) on pins 51-53. Pin 50 is the input for the insertion control signal called 'FBL-1'. When this signal level becomes higher than 0.9 V (but less than 3 V), the RGB signals at pins 51, 52, and 53 are inserted into the picture by using the internal switches.Also, some picture improvement features are implemented in this part:• Black stretch. This function corrects the black level of

incoming signals, which have a difference between the black level and the blanking level. The amount of extension depends upon the difference between actual black level and the darkest part of the incoming video signal level. It is detected by means of an internal capacitor.

• White stretch. This function adapts the transfer characteristic of the luminance amplifier in a non-linear way depending on the average picture content of the luminance signal. It operates in such a way that maximum stretching is obtained when signals with a low video level are received. For bright pictures, stretching is not active.

• Dynamic skin tone correction. This circuit corrects (instantaneously and locally) the hue of those colors, which are located in the area in the UV plane that matches the skin tone. The correction is dependent on the luminance, saturation, and distance to the preferred axis.

The YUV signal is then fed to the color matrix circuit, which converts it to R, G, and B signals. The OSD/TXT signal from the microprocessor is mixed with the main signal at this point, before being output to the CRT board (pins 56, 57, and 58).

9.3.6 RGB Control

The RGB control circuit enables the picture parameters contrast, brightness, and saturation to be adjusted, by using a combination of the user menus and the remote control. Additionally automatic gain control for the RGB signals via cut-off stabilization is achieved in this functional block to obtain an accurate biasing of the picture tube. Therefore, this block

inserts the cut-off point measuring pulses into the RGB signals during the vertical retrace period. The following additional controls are used:• Black current calibration loop. Because of the 2-point

black current stabilization circuit, both the black level and the amplitude of the RGB output signals depend on the drive characteristics of the picture tube. The system checks whether the returning measuring currents meet the requirements, and adapt the output level and gain of the circuit when necessary. After stabilization of the loop, the RGB drive signals are switched on. The 2-point black level system adapts the drive voltage for each cathode in such a way that the two measuring currents have the right value. This is done with the measurement pulses during the frame flyback. During the first frame, three pulses with a current of 8 µA are generated to adjust the cut off voltage. During the second frame, three pulses with a current of 20 µA are generated to adjust the 'white drive'. This has as a consequence, that a change in the gain of the output stage will be compensated by a gain change of the RGB control circuit. Pin 55 (BLKIN) of the UOC is used as the feedback input from the CRT base panel.

• Blue stretch. This function increases the color temperature of the bright scenes (amplitudes which exceed a value of 80% of the nominal amplitude). This effect is obtained by decreasing the small signal gain of the red and green channel signals, which exceed this 80% level.

• Beam current limiting. A beam current limiting circuit inside the UOC handles the contrast and brightness control for the RGB signals. This prevents the CRT from being overdriven, which could otherwise cause serious damage in the line output stage. The reference used for this purpose is the DC voltage on pin 54 (BLCIN) of the TV processor. Contrast and brightness reduction of the RGB output signals is therefore proportional to the voltage present on this pin. Contrast reduction starts when the voltage on pin 54 is lower than 2.8 V. Brightness reduction starts when the voltage on pin 54 is less than 1.7 V. The voltage on pin 54 is normally 3.3 V (limiter not active). During set switch-off, the black current control circuit generates a fixed beam current of 1 mA. This current ensures that the picture tube capacitance is discharged. During the switch-off period, the vertical deflection is placed in an over-scan position, so that the discharge is not visible on the screen.

9.3.7 RGB Amplifier

From outputs 56, 57, and 58 of IC 7200 the RGB signals are applied to the integrated output amplifier (7330) on the CRT panel. Via the outputs 7, 8, and 9, the picture tube cathodes are driven.The supply voltage for the amplifier is +200 V and is derived from the line output stage.

9.3.8 Eco Scavem (diagram B2 if present)

The SCAn VElocity Modulation (Scavem) circuitry is implemented in the layout of the picture tube panel. It is thus not an extra module. This circuit influences the horizontal deflection as a function of the picture content. In an ideal square wave, the sides are limited in slope due to a limited bandwidth (5 MHz). Scavem will improve the slope as follows: • At a positive slope, a Scavem current is generated which

supports the deflection current. At the first half of the slope, the spot is accelerated and the picture is darker. At the second half of the slope, the spot is delayed and the slope becomes steeper.

• At the end of the slope, the Scavem-current decays to zero and the spot is at the original position. An overshoot occurs which improves the impression of sharpness.

• At the negative slope, the Scavem-current counteracts the deflection. During the first half of the slope, the spot is delayed and the slope becomes steeper. During the second half the spot accelerates, the Scavem-current is zero at the end of the slope.

The RGB signals are fed into the Scavem circuit and differentiated by C2364/2365/2366 and the input impedance of the TS7360 stage. Diode D6364 (Schottky diode) is the coring component, which blocks all the signals below 0.3 V so that the noise is not amplified and all the signals larger than 0.3 V are differentiated and amplified. After differentiation, the signal is amplified by TS7360 with R3369 as the collector resistor. The biasing of the TS7360 stage is done by R3369, R3361, R3360, R3362, and R3363. Items D6367, C2367, R3367, R3361, and C2360 work as the clipping components that limit the Scavem current at a certain level, to prevent Scavem over-correction.After being buffered by TS7369, the differentiated signals are coupled through C2375 and C2380 to the output stage. The output stage is configured into cascode stage and push-pull operation. The biasing is done by R3373, R3375, R3376, R3380, R3381, R3383, R3374, and R3384. The working voltage of the transistors is settled at half the supply voltage.At the rising portion of the RGB signals, cascode TS7380 and TS7382 will be operating and will pull the current through the Scavem coil. Contrarily, at the falling portion of the RGB signals, cascode TS7373 and TS7366 will be operating and will push the current through the Scavem coil. The capacitors C2362, C2373, and C2381 ground the high frequencies, to prevent high frequency amplification. The ferrite bead L5376 is for EMC purpose. Resistors R3374 and R3384 determine the output Scavem current. Items C2378 and R3378 are for the fine-tuning for different Scavem coil impedances. They also help to suppress high frequency oscillation. Capacitor C2369 helps to suppress the high frequency components and controls the Scavem delay.

9.4 Synchronization

Inside IC 7200 part D, the vertical and horizontal sync pulses are separated. These 'H' and 'V' signals are synchronized with the incoming CVBS signal. They are then fed to the H- and V-drive circuits and to the OSD/TXT circuit for synchronization of the On Screen Display and Teletext (CC) information.

9.5 Deflection

Please use the diagrams in chapter 6 and/or 7 for elucidation of the descriptions below.

9.5.1 Horizontal Drive

The horizontal drive signal is obtained from an internal VCO, which is running at twice the line frequency. This frequency is divided by two, to lock the first control loop to the incoming signal.When the IC is switched 'on', the 'Hdrive' signal is suppressed until the frequency is correct.The 'Hdrive' signal is available at pin 30. The 'Hflybk' signal is fed to pin 31 to phase lock the horizontal oscillator, so that TS7462 cannot switch 'on' during the flyback time. The 'EWdrive' signal for the E/W circuit (if present) is available on pin 15, where it drives transistor TS7400 to make linearity corrections in the horizontal drive. When the set is switched on, the '+8V' voltage goes to pin 9 of IC7200. The horizontal drive starts up in a soft start mode. It starts with a very short T_on time of the horizontal output transistor. The T_off of the transistor is identical to the time in normal operation. The starting frequency during switch on is


therefore about 2 times higher than the normal value. The 'on' time is slowly increased to the nominal value in 1175 ms. When the nominal value is reached, the PLL is closed in such a way that only very small phase corrections are necessary. The 'EHTinformation' line on pin 11 is intended to be used as a 'X-ray' protection. When this protection is activated (when the voltage exceeds 6 V), the horizontal drive (pin 30) is switched 'off' immediately. If the 'H-drive' is stopped, pin 11 will become low again. Now the horizontal drive is again switched on via the slow start procedure. The 'EHTinformation' line (Aquadag) is also fed back to the UOC IC 7200 pin 54, to adjust the picture level in order to compensate for changes in the beam current. The filament voltage is monitored for 'no' or 'excessive' voltage. This voltage is rectified by diode 6447 and fed to the emitter of transistor 7443. If this voltage goes above 6.8 V, transistor 7443 will conduct, making the 'EHT0' line 'high'. This will immediately switch off the horizontal drive (pin 30) via the slow stop procedure. The horizontal drive signal exits IC7200 at pin 30 and goes to TS7462, the horizontal driver transistor. The signal is amplified and coupled to the base circuit of TS7460, the horizontal output transistor. This will drive the line output transformer (LOT) L5445 and the associated circuit. The LOT provides the extra high voltage (EHT), the VG2 voltage and the focus and filament voltages for the CRT, while the line output circuit drives the horizontal deflection coil.

9.5.2 Vertical Drive

A divider circuit performs the vertical synchronization. The vertical ramp generator needs an external resistor (R3245, pin 20) and capacitor (C2244, pin 21). A differential output is available at pins 16 and 17, which are DC-coupled with the vertical output stage. During the insertion of RGB signals, the maximum vertical frequency is increased to 72 Hz so that the circuit can also synchronize on signals with a higher vertical frequency like VGA.To avoid damage of the picture tube when the vertical deflection fails, the guard output is fed to the beam current limiting input. When a failure is detected, the RGB-outputs are blanked. When no vertical deflection output stage is connected, this guard circuit will also blank the output signals. These 'V_DRIVE+' and 'V_DRIVE-' signals are applied to the input pins 1 and 2 of IC 7471 (full bridge vertical deflection amplifier). These are voltage driven differential inputs. As the driver device (IC 7200) delivers output currents, R3474 and R3475 convert them to voltage. The differential input voltage is compared with the voltage across measuring resistor R3471 that provides internal feedback information. The voltage across this measuring resistor is proportional to the output current, which is available at pins 4 and 7 where they drive the vertical deflection coil (connector 0222) in phase opposition.IC 7471 is supplied by +13 V. The vertical flyback voltage is determined by an external supply voltage at pin 6 (VlotAux+50V). This voltage is almost totally available as flyback voltage across the coil, this being possible due to the absence of a coupling capacitor (which is not necessary, due to the 'bridge' configuration).

9.5.3 Deflection Corrections (see diagram A2)

The Linearity CorrectionA constant voltage on the horizontal (or line) deflection coil should result in a sawtooth current. This however is not the case as the resistance of the coil is not negligible. In order to compensate for this resistance, a pre-magnetized coil L5457 is used. R3485 and C2459 ensure that L5457 does not excite,

because of its own parasite capacitance. This L5457 is called the 'linearity coil'.

The Mannheim EffectWhen clear white lines are displayed, the high-voltage circuit is heavily loaded. During the first half of the flyback, the high voltage capacitors are considerable charged. At that point in time, the deflection coil excites through C2465. This current peak, through the high-voltage capacitor, distorts the flyback pulse. This causes synchronization errors, causing an oscillation under the white line. During the second half of the flyback, C2490//2458 is charged via R3459. At the moment of the flyback, C2490//2458 is subjected to the negative voltage pulses of the parabola because of which D6465 and D6466 are conducting and C2490//2458 is switched in parallel with C2456//2457. The high-voltage diodes are conducting this moment. Now extra energy is available for excitation through C2465 and the line deflection. Consequently, the flyback pulse is less distorted.

The S-CorrectionSince the sides of the picture are further away from the point of deflection than from the center, a linear sawtooth current would result in a non-linear image being scanned (the center would be scanned slower than the sides). For the center-horizontal line, the difference in relation of the distances is larger then those for the top and bottom lines. An S-shaped current will have to be superimposed onto the sawtooth current. This correction is called finger-length correction or S-correction. C2456//2457 is relatively small, as a result of which the sawtooth current will generate a parabolic voltage with negative voltage peaks. Left and right, the voltage across the deflection coil decreases, and the deflection will slow down; in the center, the voltage increases and deflection is faster. The larger the picture width, the higher the deflection current through C2456//2457. The current also results in a parabolic voltage across C2484//2469, resulting in the finger length correction proportionally increasing with the picture width. The east/west drive signal will ensure the largest picture width in the center of the frame. Here the largest correction is applied.

East/West CorrectionIn this chassis, there are three types of CRTs, namely the 100 deg., 110 deg., and wide screen CRTs. The 100 deg. CRT is raster-correction-free and does not need East/West correction. The 110 deg. 4:3 CRT comes with East/West correction and East/West protection. The wide screen TV sets have all the corrections of the 110 deg. 4:3 CRT, but also have additional picture formats like the 4:3 format, 16:9, 14:9, 16:9 zoom, subtitle zoom, and the Super-Wide picture format A line, written at the upper- or lower side of the screen, will be larger at the screen center when a fixed deflection current is used. Therefore, the amplitude of the deflection current must be increased when the spot approaches the center of the screen. This is called the East/West or pincushion correction. The 'Ewdrive' signal from pin 15 of IC 7200 takes care for the correct correction. It drives FET 7400. It also corrects breathing of the picture, due to beam current variations (the EHT varies dependent of the beam current). This correction is derived from the 'EHTinformation' line.Two protections are built-in for the E/W circuit: over-current and over-voltage protection. See paragraph 'Protection Events'.

PanoramaThe panorama function is only used in 16:9 sets. This is a function to enable the 4:3 and Super-Wide feature. It drives the 'Bass_panorama' line, to activate relay 1400. When this relay is switched on, the capacitors 2453 and 2454 are added in parallel to the default S-correction capacitors 2456 and 2457. This results in an increased capacitance, a lower resonance


frequency of the line deflection coil and the S-correction capacitors and therefore a less steep S-corrected line deflection current.

9.6 Power Supply

Figure 9-4 Switched Mode Power Supply standard circuit

Figure 9-5 Internal block diagram of the driver IC (TEA1507)

9.6.1 Introduction

The supply is a Switching Mode Power Supply (SMPS). The frequency of operation varies with the circuit load. This 'Quasi-Resonant Flyback' behavior has some important benefits compared to a 'hard switching' fixed frequency Flyback converter. The efficiency can be improved up to 90%, which results in lower power consumption. Moreover, the supply runs cooler and safety is enhanced.The power supply starts operating when a DC voltage goes from the rectifier bridge via T5520, R3532 to pin 8. The operating voltage for the driver circuit is also taken from the 'hot' side of this transformer. The switching regulator IC 7520 starts switching the FET 'on' and 'off', to control the current flow through the primary winding of transformer 5520. The energy stored in the primary winding during the 'on' time is delivered to the secondary windings during the 'off' time. The 'MainSupply' line is the reference voltage for the power supply. It is sampled by resistors 3543 and 3544 and fed to the

input of the regulator 7540 / 6540. This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 3 of 7520. The power supply in the set is 'on' any time AC power goes to the set.

Derived VoltagesThe voltages supplied by the secondary windings of T5520 are:• 'MainAux' for the audio circuit (voltage depends on set

execution, see table below),• 3.3 V and 3.9 V for the microprocessor and• 'MainSupply' for the horizontal output (voltage depends on

set execution, see table below). Other supply voltages are provided by the LOT. It supplies +50 V (only for large screen sets), +13 V, +8 V, +5 V, and a +200 V source for the video drive. The secondary voltages of the LOT are monitored by the 'EHTinformation' lines. These lines are fed to the video processor part of the UOC IC 7200 on pins 11 and 34. This circuit will shut 'off' the horizontal drive in case of over-voltage or excessive beam current.

Figure 9-6 Derived voltages

DegaussingWhen the set is switched on, the degaussing relay 1515 is immediately activated as transistor 7580 is conducting. Due to the RC-time of R3580 and C2580, it will last about 3 to 4 seconds before transistor 7580 is switched off.

9.6.2 Basic IC Functionality

For a clear understanding of the Quasi-Resonant behavior, it is possible to explain it by a simplified circuit diagram (see Figure below). In this circuit diagram, the secondary side is transferred to the primary side and the transformer is replaced by an inductance L_p. Capacitor C_d is the total drain capacitance including the resonance capacitor C_r, parasitic output capacitor C_oss of the MOSFET and the winding capacitance C_w of the transformer. The turn ratio of the transformer is represented by n (N_p/N_s).

Figure 9-7 QR-mode time intervals

In the Quasi-Resonant mode each period can be divided into four different time intervals, in chronological order:• Interval 1: t0 < t < t1 primary stroke. At the beginning of

the first interval, the MOSFET is switched 'on' and energy is stored in the primary inductance (magnetization). At the end, the MOSFET is switched 'off' and the second interval starts.

• Interval 2: t1 < t < t2 commutation time. In the second interval, the drain voltage will rise from almost zero to V_in+n•(V_out+V_f). V_f is the forward voltage drop of de diode that will be omitted from the equations from now on. The current will change its positive derivative, corresponding to V_in/L_p, to a negative derivative, corresponding to -n•(V_out/L_p).

• Interval 3: t2 < t < t3 secondary stroke. In the third interval, the stored energy is transferred to the output, so the diode starts to conduct and the inductive current Il will decrease. In other words, the transformer will be demagnetized. When the inductive current has become zero the next interval begins.

• Interval 4: t3 < t < t00 resonance time. In the fourth interval, the energy stored in the drain capacitor C_d will start to resonate with the inductance L_p. The voltage and current waveforms are sinusoidal waveforms. The drain voltage will drop from V_in+(n•V_out) to V_in-(n•V_out).

Frequency BehaviorThe frequency in the QR-mode is determined by the power stage and is not influenced by the controller (important parameters are L_p and C_d). The frequency varies with the input voltage V_in and the output power P_out. If the required output power increases, more energy has to be stored in the transformer. This leads to longer magnetizing t_prim and demagnetizing t_sec times, which will decrease the frequency. See the frequency versus output power characteristics below. The frequency characteristic is not only output power-, but also input voltage dependent. The higher the input voltage, the smaller t_prim, so the higher the frequency will be.

Figure 9-8 QR frequency behavior

Point P1 is the minimum frequency f_min that occurs at the specified minimum input voltage and maximum output power required by the application. Of course, the minimum frequency has to be chosen above the audible limit (>20 kHz).

Start-Up SequenceWhen the rectified AC voltage V_in (via the center tap connected to pin 8) reaches the Mains dependent operation level (Mlevel: between 60 and 100 V), the internal 'Mlevel switch' will be opened and the start-up current source is enabled to charge capacitor C2521 at the V_cc pin as shown below. The 'soft start' switch is closed when the V_cc reaches a level of 7 V and the 'soft start' capacitor C_ss (C2522, between pin 5 and the sense resistor R3526), is charged to 0.5 V. Once the V_cc capacitor is charged to the start-up voltage V_start (11 V), the IC starts driving the MOSFET. Both internal current sources are switched 'off' after reaching this start-up voltage. Resistor R_ss (3524) will discharge the 'soft start' capacitor, such that the peak current will slowly increase. This to prevent 'transformer rattle'. During start-up, the V_cc capacitor will be discharged until the moment that the primary auxiliary winding takes over this voltage.

CL 16532020_078.eps110401


The moment that the voltage on pin 1 drops below the 'under voltage lock out' level (UVLO = ± 9 V), the IC will stop switching and will enter a safe restart from the rectified mains voltage.

OperationThe supply can run in three different modes depending on the output power:• Quasi-Resonant mode (QR). The 'QR' mode, described

above, is used during normal operation. This will give a high efficiency.

• Frequency Reduction mode (FR). The 'FR' mode (also called 'VCO' mode) is implemented to decrease the switching losses at low output loads. In this way, the efficiency at low output powers is increased, which enables power consumption smaller than 3 W during stand-by. The voltage at the pin 3 (Ctrl) determines where the frequency reduction starts. An external Ctrl voltage of 1.425 V corresponds with an internal VCO level of 75 mV. This fixed VCO level is called V_vco,start . The frequency will be reduced in relation to the VCO voltage between 75 mV and 50 mV (at levels larger than 75 mV, Ctrl voltage < 1.425V, the oscillator will run on maximum frequency f_oscH = 175 kHz typically). At 50 mV (V_vco,max), the frequency is reduced to the minimum level of 6 kHz. Valley switching is still active in this mode.

• Minimum Frequency mode (MinF). At VCO levels below 50 mV, the minimum frequency will remain on 6 kHz, which is called the 'MinF' mode. Because of this low frequency, it is possible to run at very low loads without having any output regulation problems.

Figure 9-10 Different supply modes

Safe-Restart ModeThis mode is introduced to prevent the components from being destroyed during eventual system fault conditions. It is also used for the Burst mode. The Safe-Restart mode will be entered if it is triggered by one of the following functions:• Over voltage protection,• Short winding protection,• Maximum 'on time' protection,• V_cc reaching UVLO level (fold back during overload),• Detecting a pulse for Burst mode,• Over temperature protection. When entering the Safe-Restart mode, the output driver is immediately disabled and latched. The V_cc winding will not charge the V_cc capacitor anymore and the V_cc voltage will drop until UVLO is reached. To recharge the V_cc capacitor, the internal current source (I_(restart)(vcc) ) will be switched 'on' to initiate a new start-up sequence as described before. This Safe-Restart mode will persist until the controller detects no faults or burst triggers.

Standby The set goes to Standby in the following cases:• After pressing the 'standby' key on the remote control.• When the set is in protection mode.

In Standby, the power supply works in 'burst mode'. Burst mode can be used to reduce the power consumption below 1 W at stand-by. During this mode, the controller is active (generating gate pulses) for only a short time and for a longer time inactive waiting for the next burst cycle.In the active period, the energy is transferred to the secondary and stored in the buffer capacitor C_stab in front of the linear stabilizer (see figure below). During the inactive period, the load (e.g. microprocessor) discharges this capacitor. In this mode, the controller makes use of the Safe-Restart mode.

Figure 9-11 Supply standby mode (burst mode)

The system enters burst mode standby when the microprocessor activates the 'Stdby_con' line. When this line is pulled high, the base of TS7541 is allowed to go high. This is triggered by the current from collector TS7542. When TS7541 turns 'on', the opto-coupler (7515) is activated, sending a large current signal to pin 3 (Ctrl). In response to this signal, the IC stops switching and enters a 'hiccup' mode. This burst activation signal should be present for longer than the 'burst blank' period (typically 30 s): the blanking time prevents false burst triggering due to spikes.Burst mode standby operation continues until the microcontroller pulls the 'Stdby_con' signal low again. The base of TS7541 is unable to go high, thus cannot turn 'on'. This will disable the burst mode. The system then enters the start-up sequence and begins normal switching behavior. For a more detailed description of one burst cycle, three time intervals are defined:• t1: Discharge of V_cc when gate drive is active. During

the first interval, energy is transferred, which result in a ramp-up of the output voltage (V_stab) in front of the stabilizer. When enough energy is stored in the capacitor, the IC will be switched 'off' by a current pulse generated at the secondary side. This pulse is transferred to the primary side via the opto coupler. The controller will disable the output driver (safe restart mode) when the current pulse reaches a threshold level of 16 mA into the 'Ctrl' pin. A resistor R1 (R3519) is placed in series with the opto coupler, to limit the current going into the 'Ctrl' pin. Meanwhile the V_cc capacitor is discharged but has to stay above V_uvlo .

• t2: Discharge of V_cc when gate drive is inactive. During the second interval, the V_cc is discharged to V_uvlo. The output voltage will decrease depending on the load.

• t3: Charge of V_cc when gate drive is inactive. The third interval starts when the UVLO is reached. The internal current source charges the V_cc capacitor (also the soft start capacitor is recharged). Once the V_cc capacitor is charged to the start-up voltage, the driver is activated and a new burst cycle is started.

9.6.3 Protection Events

The SMPS IC 7520 has the following protection features:

Demagnetization senseThis feature guarantees discontinuous conduction mode operation in every situation. The oscillator will not start a new primary stroke until the secondary stroke has ended. This is to ensure that FET 7521 will not turn on until the demagnetization of transformer 5520 is complete. The function is an additional protection feature against:• Saturation of the transformer.• Damage of the components during initial start-up.• An overload of the output. The demag(netization) sense is realized by an internal circuit that guards the voltage (V_demag) at pin 4 that is connected to V_cc winding by resistor R1 (R3522). The figure below shows the circuit and the idealized waveforms across this winding.

Figure 9-13 Demagnetization protection

Over Voltage ProtectionThe Over Voltage Protection ensures that the output voltage will remain below an adjustable level. This works by sensing the auxiliary voltage via the current flowing into pin 4 (DEM) during the secondary stroke. This voltage is a well-defined replica of the output voltage. Any voltage spikes are averaged by an internal filter. If the output voltage exceeds the OVP trip level, the OVP circuit switches the power MOSFET 'off'. Next, the controller waits until the 'under voltage lock out' level (UVLO = ± 9 V) is reached on pin 1 (V_cc). This is followed by a safe restart cycle, after which switching starts again. This process is repeated as long as the OVP condition exists. The output voltage at which the OVP function trips, is set by the demagnetization resistor R3522.

Over Current ProtectionThe internal OCP protection circuit limits the 'sense' voltage on pin 5 to an internal level.

Over Power ProtectionDuring the primary stroke, the rectified AC input voltage is measured by sensing the current drawn from pin 4 (DEM). This current is dependent on the voltage on pin 9 of transformer 5520 and the value of R3522. The current information is used to adjust the peak drain current, which is measured via pin I_sense.

Short Winding ProtectionIf the 'sense' voltage on pin 5 exceeds the short winding protection voltage (0.75 V), the converter will stop switching. Once V_cc drops below the UVLO level, capacitor C2521 will be recharged and the supply will start again. This cycle will be repeated until the short circuit is removed (safe restart mode).The short winding protection will also protect in case of a secondary diode short circuit.This protection circuit is activated after the leading edge blanking time (LEB).

LEB timeThe LEB (Leading Edge Blanking) time is an internally fixed delay, preventing false triggering of the comparator due to current spikes. This delay determines the minimum 'on' time of the controller.

Over Temperature protectionWhen the junction temperature exceeds the thermal shutdown temperature (typ. 140 deg. C), the IC will disable the driver. When the V_cc voltage drops to UVLO, the V_cc capacitor will be recharged to the V(start) level. If the temperature is still too high, the V_cc voltage will drop again to the UVLO level (Safe-Restart mode). This mode will persist until the junction temperature drops 8 degrees typically below the shutdown temperature.

Mains dependent operation enabling levelTo prevent the supply from starting at a low input voltage, which could cause audible noise, a mains detection is implemented (Mlevel). This detection is provided via pin 8, which detects the minimum start-up voltage between 60 and 100 V. As previous mentioned, the controller is enabled between 60 and 100 V.An additional advantage of this function is the protection against a disconnected buffer capacitor (C_in). In this case, the supply will not be able to start-up because the V_cc capacitor will not be charged to the start-up voltage.

9.7 Control

Figure 9-14 Block diagram set control

9.7.1 Introduction

The microprocessor part of the UOC, has the complete control and teletext on board. User menu, Service Default Mode, Service Alignment Mode and Customer Service Mode are generated by the uP. Communication to other ICs is done via the I2C-bus.

9.7.2 I2C-Bus

The main control system, which consists of the microprocessor part of the UOC (7200), is linked to the external devices (tuner, NVM, MSP, etc) by means of the I2C-bus. An internal I2C-bus is used to control other signal processing functions, like video processing, sound IF, vision IF, synchronization, etc.

9.7.3 User Interface

The 'L01.1L AC' uses a remote control with RC5 protocol. The incoming signal is connected to pin 67 of the UOC. The 'Top Control' keyboard, connected to UOC pin 80, can also control the set. Button recognition is done via a voltage divider. The front LED (6691) is connected to an output control line of the microprocessor (pin 5). It is activated to provide the user information about whether or not the set is working correctly (e.g., responding to the remote control, normal operation (USA only) or fault condition)

9.7.4 In- and Output Selection

For the control of the input and output selections, there are three lines: • STATUS1. This signal provides information to the

microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe). This signal is not connected in NAFTA sets.

• STATUS2. This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe).

For sets with an SVHS input it provides the additional information if a Y/C or CVBS source is present. The presence of an external Y/C source makes this line 'high' while a CVBS source makes the line 'low'.

• SEL-MAIN-FRNT-RR. This is the source select control signal from the microprocessor. This control line is under user control or can be activated by the other two control lines.

9.7.5 Power Supply Control

The microprocessor part is supplied with 3.3 V and 3.9 V both derived from the 'MainAux' voltage via a 3V3 stabilizer (7560) and a diode.Two signals are used to control the power supply:• Stdby_con. This signal is generated by the

microprocessor when over-current takes place at the 'MainAux' line. This is done to enable the power supply into standby burst mode, and to enable this mode during a protection. This signal is 'low' under normal operation conditions and goes to 'high' (3.3 V) under 'standby' and 'fault' conditions.

• POWER_DOWN. This signal is generated by the power supply. Under normal operating conditions, this signal is 'high' (3.3 V). During 'standby' mode, this signal is a pulse train of approx. 10 Hz and a 'high' duration of 5 ms. It is used to give information to the UOC about the fault condition in the Audio amplifier supply circuit. This information is generated by sensing the current on the 'MainAux' line (using voltage drop across R3564 to trigger TS7562). This signal goes 'low' when the DC-current on the 'MainAux' line exceeds 1.6 - 2.0 A. It is also used to give an early warning to the UOC about a power failure. Then the information is used to mute the sound amplifier to prevent a switch off noise and to solve the switch-off spot.

9.7.6 Protection Events

Several protection events are controlled by the UOC: • BC protection, to protect the picture tube from a too high

beam current. The UOC has the capability of measuring the normal back level current during the vertical flyback. So if for some reason the CRT circuit is malfunctioning (i.e. high beam current), the normal black current will be out of the 75 uA range, and the UOC will trigger the power supply to shut down. However, this is a high beam-current situation, the TV screen will be bright white before the set is shut down.

• E/W protection, two protection mechanisms are built in, over-current and over-voltage. – In case of over-current due to defective parts in the line

deflection output stage, a high current will flow through resistors 3405//3406. If this current is large enough to create a voltage drop of 0.7 V across 3405//3406, transistor TS7606 (in A7 diagram) will conduct and pin 80 of the UOC will be pulled down. Thereafter, the UOC will shut down the power supply. In case of further current increase, the fused resistor 3411 is built-in for double protection.

– In case of a high voltage appearing across capacitor 2401 (dependent of the tube size), which is high enough to trigger zener diode 6401 into conduction, transistor TS7606 (in A7 diagram) will conduct and UOC is triggered to shut down the power supply.

• I2C protection, to check whether all I2C ICs are functioning.

In case one of these protections is activated, the set will go into 'standby'. The 'on' and 'standby' LEDs are controlled via the UOC.
