After pressing the right cursor but-ton on the remote, the main menuwill appear.
A full explanation of all of the menusettings are available in the DFUfound on the customer website atwww.p4c.philips.com.
If a customer complains of thepicture being clipped, they mayneed to select a different pictureformat. Broadcast stations whenupconverting from NTSC toDigital, may transmit black barson the sides to maintain a 4x3aspect ratio on a 16x9 screen.The Automatic mode will detectthese bars to fill out the picture.Clipping on the top and bottom ofthe picture may occur in thismode. If the station is broadcast-
ing something other than black bars (grey forexample), the set will not detect the bars and fillout the picture.
Ambilights are available on some of the LCD ver-sion of the EJ3.0. The Ambilight assemblies aremounted in the rear cover of the set. They useLEDs instead of the fluorescent lamps used inpast versions. The driver circuits are mounted ineach light assembly. They are powered by a 12volt supply from the power supply and arecontrolled by the I
2C Bus from the SSB.

Type of Service
The EJ3.0 is designed for board level repair in warranty. There are parts and serviceinformation available for component level service of the SSB and Ambilight interconnectboard.
Overview
Set is designed for board level repair
Parts for component level repair are only available for the SSB and Ambilightinterconnect boards
Plasma panels should repaired to board level
LCD panels should be repaired to board level
EJ3.0 LCD Version (Figure 2)
The LCD version has a single power supply , SSB, and Ambilight Interconnect panels. Thereis not service information or parts available for the power supply panel. It is designed forreplacement only in service.
Board level troubleshooting for EJ3.0 LA, LCD version Figure 3
In the standby mode, two voltages are present on 1J02 on the SSB. The 5 volt standbyvoltage on pins 4 and 5 and the Standby (STBY) voltage on pin 11. When the set is turnedOn, the STBY line should go Low. This will switch On the main power supply voltages. The12VS supply can be read on pins 9 and 10 and the -18 and +18 volt supplies can be read onpins 1 and 2 with the set On. The plus and minus 18 volt supplies are the audio amplifiersupply voltages. The Audio Amplifier is located on the SSB.
If the STBY line does not go Low, check the Keyboard line on pin 2 of 1M01. This voltageshould go Low when the power button is pressed.
The Power Supply also produces a 24 volt supply for the backlight inverters on the LCDpanel. The DIM CTL voltage from the SSB controls the brightness of the backlight. It can bemeasured on pin 12 of 1J02. The command to switch on the backlight is the LAMP ON sig-nal which can be measured on pin 13 of 1J02.
page 7
The audio amplifier is located on the SSB. Speakers are connected on 1740 of the SSB. Aproblem in the audio amplifier causing a DC voltage on the speaker lines will cause the set toshut down. This will generate a error code 14. To troubleshoot, disconnect the wires frompins 1 and 2 of 1J02 of the SSB to remove power to the audio amplifier. If the set runs,check to see if the voltages on the power supply are correct. If they are correct, change theSSB.
The Ambilight interconnect board is present even if the set does not have the Ambilight fea-ture. The LVDS signal from the SSB is fed to the Interconnect board which performs videoenhancement.
The Ambilight is controlled by the I2C bus from the SSB. This I2C bus controls the videoenhancement IC located on the Ambilight board.

SSB and Ambilight indicators
The bottom LED on the SSB (top picture) indicates that the viper IC has booted. The topLED indicates that 12 volts is present for the display. This voltage not only powers the dis-play, but also powers the video enhancement IC on the Ambilight board.
The Ambilight interconnect is shown in the bottom picture. The LED on the right shows thatthe 12 volt display voltage from the SSB is present. The left LED indicates that the 12 voltsto the controller board is present. If the picture is not present and backlight is On, check forthe 12 volt supply to the LCD panel controller board. Then check for the LVDS signals on theLVDS connector to the controller board. If not present, check for the LVDS signals from the
SSB.
page 10
LCD Panel backlight troubleshooting
As indicated when looking at the wiring interconnect, there are three voltages to switch on thebacklight drive, 24 volts, 3 volt power on, and 1.7 to 3 volts dim control. The dim control volt-age is normally around 3 volts when the screen is at normal brightness.
There is a Master inverter and Slave inverter board. The Master inverter board generates thecontrol signals for the lamp drive circuits. If the backlight or the Master or Slave drive is notworking the drive on both boards will shut down. An LED on the Master inverter board willturn On for approximately 4 seconds after the B+ and control voltages are fed to the board.This indicates that the controller IC on the board is working. If the backlight does not turn On,check the output of both boards as the set is turnedOn to see if the drive signal is present. If one ofthe signals is not present, change that board. If bothdrive signals are present, the panel backlight isdefective.
page 11
Plasma panel
The area highlighted is the chassis part covered by the EJ3.0 PA service manual. Except forthe Side Jack panel, IR board and Keyboard, the rest of the set is covered by the SDI PDP
repair manual.
Board Level troubleshooting
In the standby mode, the only voltages present is the +5V2_STBY and the STBY line is High.When the set is turned On, the STBY line goes Low. If the 5 volt standby is present and theSTBY does not go Low, there is a problem with the SSB. When the set turns On, the +12VSsupply on the power supply turns On. This voltage can be checked on pin 10 of 1J02.
After the set turns On, The +17 volt and -17 volt supplies then switch On, supplying power tothe audio amplifier on the SSB. A problem with the audio amplifier may cause a protectionerror (red blinking LED) code 14. If this occurs, unplug either 1M02 or CN8013 and recyclepower to the set. If the set then turns On, check the plus and minus 17 volts on CN8013 onthe Power Supply panel. If those voltages are present, replace the SSB. Read the AudioAmplifier section for a complete circuit description.
On the plasma panel, the VG voltage (15.5 volts), D5V and 3V3 voltages switch On. TheRelay On voltage switches the Logic Board On. When the Logic board turns On, the boardthen switches the VS-ON voltage High (3.2V). This switches the VS voltages on the PowerSupply. The VS voltage supplies power to the X and Y driver boards.

FIGURE 4 - PLASMA WIRING INTERCONNECT page 13
Operating the Plasma panel in a stand-alone mode
One way to determine if the problem is on the Chassis part or the Panel part is to place thePanel in a Stand-Alone mode. The panel with the SSB and Ambilight interconnect boardsneeds to be removed to give access to the Logic board.
Disconnecting CN8015 and CN8014 with switch on the panel power supply in most cases. Ifthe power supply does not switch On, ground pin 4 of CN8015 of the power supply.
To switch on the panel test pattern
Place jumper CN2013 (pins 3 and 4) on the LogicBoard. The display will start showing a cycle ofdifferent patterns.
To display a white pattern, at the moment the “fullwhite” pattern is visible, remove the jumper. Now thedisplay will show a continuous full white pattern.To restart the cycle of different patterns, replace thejumper.
If the pattern appears, this confirms that the panel isworking. The only part un-tested on the panel is the
LVDS input. This will need to bechecked with a scope afterreinstalling the SSB and Ambilightinterconnect board.
page 14
If the white screen does not turn On, check the drive signal to the panel. The Y-Drive signalcan be checked on the Y-Buffer panel. The test point is shown in the picture below. The topwaveform is the Y-Drive signal. It is approximately 1200 volts p-p. The bottom waveform isthe V-Togg signal which is the sync signal for the scope. This signal is found on the Logic
board.
The waveform to the right isthe X-Drive signal.
If either Y-Drive and X-Drive signals are not pre-sent, no picture will be dis-played. If both waveformsare present, and there is nopicture on the screen, theLogic board should bechanged.

Video Signal Flow Figure 5
The SSB tuner tunes both NTSC and ATSC channels. On the ATSC side, both terrestrial8VSB and unscrambled Cable QAM signals are tuned. The Tuner is powered by the+5VTUN voltage which is derived from the +12SW voltage.
If the selected channel is analog, IF is output on Pin 12 to 1A10, Saw Filter, and then to7C00. IC 7A00 has the Video IF Demodulator. Composite video is output on Pin 120 andthen sent to an internal AV switch via Pin 123. The AV switch selects between the compositevideo from the tuner or from one of the AV inputs. The selected composite video or YC is fedto one of two A/D converters. This signal is not broken into components as is done in a digi-tal transmission. The signal is converted from analog to digital as is. If the signal is YC, it isoutput on DLINK1. Composite video is output on DLINK3. The signal is fed to IC 7J00, AVIP.If the signal is from a YC source, it is fed to a multiplexer and output on DV3. If the signal iscomposite video, it is fed to the internal Columbus circuit. The Columbus is a 3D digital combfilter. The 3D comb processes the whole frame instead of two lines at a time as in previouscomb filters. This results in a sharper picture without cross luminance or cross color.
The AVIP converts the video to a YUV format. It is then output on the DV3 data line to 7V00,Viper.
The YUV video is fed to a Switch and video processor in the Viper which rescales the videoto fit the screen. A memory controller interfaces with two SDRAM ICs 7V01 and 7V02 whichstores the video frames as they are being processed. In the case of LCD and Plasma sets,the video is converted to a progressive scan format. In the case where this SSB is used in aPTV, the video is converted to a 1080i format. The video is fed to the video output circuitwhich outputs the signal on 3, 8 bit data lines to the AVIP. An LVDS transmitter in the AVIPoutputs the signal to the LCD or Plasma panel in an LVDS format. The OSD is added to thepicture in the Viper.
Component video signals, 480i, 480p, 720p, and 1080i are fed to 7B11, HDMI processor.This IC performs a A/D conversion before feeding the signal to the AVIP on the DV4 and DV5data lines. The HDMI signal is also fed to this IC which separates the video part of the databefore feeding it to the AVIP on DV4 and DV5.
If the customer selects an ATSC channel, the ATSC IF signal is output from the tuner on Pins14 and 15. The signal is fed to a 44 Mhz SAW filter 1T01 and IF amplifier 7T13. The signalis then fed to the ATSC decoder 7T22. The ATSC decoder captures the compressed datastream and outputs it on a 8 bit data line, DVIF. This signal is then fed to the Viper for pro-cessing. The Viper then rescales the video to fit the screen.

Audio Signal Flow (Figure 6)
All of the audio processing including the amplifier is located on the SSB. The amplifier is aclass D with an output of 15 watts per channel.
If the customer has selected an analog channel, the 4.5 Mhz sound carrier is included withthe video IF output on Pin 12 of the Tuner. The IF is fed to 7C00, MPIF, and to the VideoDemodulator and Audio Demodulator. The baseband audio is fed to an A/D converter and toData Link 3. AV inputs are fed to a switch located in 7C00 and then to one of two A/Dconverters. The audio is then output on Data Link 1 or Data Link 2.
The audio is separated in the AVIP and fed to the Audio processor. The audio processorperforms the following functions:
Master Volume control and Balance5 band equalizerVirtual Dolby processingStereo processingHeadphone volume
Processed audio is output in a I2S format and fed to the Viper. The Viper performs an Audio
Delay based on preset levels in the software. The audio is then fed back to the AVIP wherethe selected signal is fed to a D/A converter and fed to the headphone amplifier and audioamplifier.
If the customer has selected an ATSC channel, the audio data is encoded in the data streamwhich is fed to the Viper from the ATSC decoder. The selected data streams are decoded inthe MPEG2 processor and fed to the Audio Delay circuit. The I2S audio is then fed to theAVIP where it is processed and fed to the main audio and headphone amplifiers. The mainaudio is output from the Viper on AB29 to the digital output jack labeled SPDIF.
When the customer selects the HDMI input, the HDMI receiver removes the digital audio fromthe data stream and outputs it to the Viper in a I2S format.

FIGURE 7 - AUDIO AMPLIFIER AND PROTECTIONpage 20
Audio Amplifier and Protection (Figure 7)
Audio Amplifier (Figure 7A)
The Audio Amplifier is located on a separate board from the SSB. The amplifier is the samedesign as the one in the EL1.1 and EBJ1.0 chassis.
The audio amplifier consists of two class D 15 watt amplifiers. The amplifiers are powered bya +17 and -17 power supplies supplied by the Sub Power Supply on the Plasma version andthe Power Supply board on the LCD version. Since the right amplifier is identical, only theleft amplifier is shown.
Audio from the AVIP on the SSB is fed to Pin 3 of 7D00-1 which is a comparator. Feedbackfrom the output is filtered and wave-shaped by an RC network which generates a saw wave.The sawtooth waveform is applied to Pin 2. When the audio input equals the voltage on thesaw wave ramp, Pin 1 will go High. This feeds the drivers, 7D06, 7D07, 7D08, and 7D09.They then drive the outputs in 7D10. During muting, the Mute line goes High turning 7D05On forcing 7D10 into saturation, blocking the drive signal.
The base and emitter of Transistor 7D12 is connected to Resistor 3D17. When the currentreaches the point where the base is 0.6 volts less than the emitter, the Transistor will turn On.This overcurrent condition will switch the CPROT line High causing the set to shut down.
Audio Protection (Figure 7B)
The audio circuits are protected against DC voltage on the outputs and overcurrent in theamplifier.
If a DC voltage appears on the speaker lines, positive or negative, the op-amps of 7DF7 willswitch On causing Pin 7 or 1 to go Low. This will cause Transistor 7DF3 to turn Off causingthe Audio_Port to go High. Transistor 7DF4 will turn On, latching the circuit. the High on theAudio_Prot line will cause the processor to shut the set down. When this circuit latches, it willstay latched until power is removed from the set.
A High on the CPROT line will turn Transistor 7DF0 On, turning 7DF11 Off. This will turn On7DF7 causing a shutdown latch as described above. As discussed before, the CPROT linewill go High if there is an overcurrent in either the left or right audio amplifiers.

Service Alignment Mode
The following lists some of the SAM highlights. Refer to Figure 12 to view the SAM menumap.
The service alignment mode allows the service technician to check errors, clear errors,change options, read operation hours and perform alignments. (Figure 8) The SAM proce-dure should never be given to thecustomer as changes could bemade which could make the setinoperable. To enter SAM, press0 6 2 5 9 6 Info on the remotecontrol. A customer warning willthen appear on the screen. Thechannel or AV input can bechanged while in this screen.After the Next button has beenpressed, no changes to the inputcan be made. Press the Red but-ton on the remote to continue.The remote must be from a EJ,BJ, BPBL, or EM1.1 type chassis.
Press the cursor down or cursorup buttons on the remote to selectthe item in the menu. The topline indicates the menu or submenu. General and whitepoint alignmentscan be made while in the SAM.
Figure 10 shows the personaloptions menu. The Virgin modecan be selected in this menuwhich puts the set in a new out ofthe box condition.
Feature options can be set individ-ually or by changing the optionnumbers. Changing the optionswill change the option numbers.
To change the option numbers,select option numbers in themenu, then cursor right.
FIGURE 8
FIGURE 9
FIGURE 10
page 24
Enter the Option number. (Figure11) After entering the last number,the numbers will be set. If thenumbers are changed withoutentering the last number, press theOK button on the remote afterentering all of the changes. If thenumbers are entered and the cur-sor is shifted to the Group selec-tion, the number will revert to theprevious number set. A label onthe chassis of each set lists thecorrect Option Codes. If theoption numbers have beenchanged or the SSB has been replaced, the option numbers should be changed to match theoption code label.
A screen diversity code is also shown on this label. If the option code has been changed, thescreen diversity code should be correct. Selection of a different screen diversity code willchange the option code.
Note: The Option Code on the label isthe one loaded at the factory when the set is shipped. Entering this code will place theset in the out of box (Virgin) mode when the set is turned Off and back On. Any changes in customer setting will cause the Option Code to change. For example, after entering the Option Code on the label, the set will be in the Virgin (out of box) mode. After auto-program-ming the channels, the Option Code will change. The Option Code should only be enteredif the SSB has been changed or if someone has entered the wrong code.
Changing the screen diversity code to one that is not compatible with the screen may cause ablank screen. In this case the correct screen diversity code can be entered by pressing 0 6 25 9 8 menu followed by the 3 digit screen diversity code. The set will then shut Off. Thecorrect screen diversity code will be loaded when the set is turned On.
FIGURE 11
page 25
After making any changes in the SAM, cursor left to the main SAM menu and select Storeand press OK.
For the SAM menu map, refer to Figure 12.
As already indicated, errors can be read using the Service Alignment Mode. There are alsoprotection errors which will cause the set to go into a protection shutdown mode which isindicated by a blinking red light on the set. If Protection + Error blinking as shown on theerror code chart shown below, the error can be read by counting the blinks. The first digit isindicated by a slow blink. If the error is greater than 9, the second digit is indicated by a fastblink.
If not picture is present, but the set is working the errors can be read by the CSM (Customer
Service Mode.
CSM
The Customer Service Mode is a read only mode which can be used by the service techni-cian or a Call Center agent to read error codes and some set settings. To activate CSM,enter 1 2 3 6 5 4 on the remote.
If the set is not displaying a picture, but does turn On, error codes can be read by insertingUSB drive in the set before entering CSM. Any error codes will be recorded on a file on theUSB.633333
