IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUIT-ABLE FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULDBE CUT OFF AND AN APPROPRIATE PLUG FITTED. THE PLUGSEVERED FROM THE MAINS LEAD MUST BE DESTROYED AS APLUG WITH BARED WIRES IS DANGEROUS IF ENGAGED IN ALIVE SOCKET.

When an alternative type of plug is used, it should be fitted with a5 AMP FUSE, otherwise the circuit should be protected by a 5 AMPFUSE at the distribution board.

How to replace the fuse.Open the fuse compartment witha screwdriver blade and replacethe fuse.

FE-2 SELF DIAGNOSTIC SOFTWARE

The identification of errors within the FE-2 chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the eventof one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flashingLED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device numberwill be displayed through the LED (Series of flashes which must be counted) See table 1., non fatal errors are reported using this method.Each time the software detects an error it is stored within the NVM. See Table 2.

Flash Timing Example : e.g. error number 3

SECTION 2 DISASSEMBLY

2-1. Rear Cover Removal

Release the mains power cable from its securing posts.Remove the rear cover fixing screws indicated. Pull the rearcover away from the front beznet. Take care when removingthe rear cover not to damage the speaker cables as speakersare fitted inside the rear cover.

2-2. Speaker Connector Disconnection

Before completely removing the rear cover disconnect thespeaker connectors which are located on the inside base ofthebeznet.

2-3. Chassis Removal and Refitting

To remove lift the main bracket rear slightly and slide thechassis away from the beznet. Ensure that theinterconnecting leads are released from their purse locks toprevent damage being caused.

When refitting the chassis ensure that the main bracket islocated in the beznet guide slots before sliding the chassisforwards. Refit the interconnecting leads in their respectivepurse locks.

Screw.

Release the 5 securing clips located at the side and front of thechassis and slide the PWB clear of the bracket.

Place the A Board PWB in the position indicated to carry outservicing.

Remove the two screws fixing the user control module to theside of the set. The control module can then be removed bysliding it towards the rear of the set allowing access to theH2 Board.

How to handle the Anode-Cap

1. To prevent damaging the surface of the anode-cap do not usesharp materials.

2. Do not apply too great a pressure on the rubber, as this may causedamage to the anode connector.

3. A metal fitting called a shatter hook terminal is fitted inside therubber cap.

4. Do not turn the rubber foot over excessively, this may causedamage if the shatter hook sticks out.

Removal of the Anode-Cap

2-8. Picture Tube Removal

WARNING:BEFORE REMOVING

THE ANODE CAP

High voltage remains in the CRT evenafter the power is disconnected. Toavoid electric shock, discharge CRTbefore attempting to remove the anodecap. Short between anode and CRTcoated earth ground strap.

1. Discharge the anode of the CRT and remove the anode cap.2. Release the EHT lead from its CRT support bracket.3. Unplug all interconnecting leads from the Deflection yoke,

degaussing coils, Rotation coil and CRT grounding strap.4. Remove the C Board from the CRT.5. Loosen the VM Block fixing screw and remove.6. Remove the chassis assembly.7. Loosen the Deflection yoke fixing screw and remove.8. Remove the Degaussing Coil holders.9. Place the set with the CRT face down on a cushion.10. Unscrew the four CRT fixing screws [ located on each CRT

Preparation:1. In order to reduce the influence of geomagnetism on the

set’s picture tube, face it in an easterly or westerly direction.2. Switch on the set’s power and degauss with the degausser.

1. Input an all white signal from the pattern generator. Set theContrast and Brightness to normal.

2. Set the pattern generator raster signal to Red.3. Move the deflection yoke forward and adjust with the

purity control so that the Red is at the centre and the Blueand Green take up equally sized areas on each side of thescreen. [See Fig.3-1 - 3-3].

4. Move the deflection yoke backwards and adjust so that theentire screen becomes Red. [See Fig.3-1]

5. Switch the raster signal to Blue, then to Green and verifythe condition.

6. When the position of the deflection yoke has beendetermined, fasten the deflection yoke with the screws.

7. If the beam does not land correctly in all the corners, use amagnet to correct it. [See Fig.3-4]

• When complete readjustment is necessary or a new picturetube is installed, carry out the following adjustments.

• Unless there are specific instructions to the contrary, carryout these adjustments with the rated power supply.

• Unless there are specific instructions to the contrary, set thecontrols and switches to the following settings :

Contrast .................... 80% [or remote control normal]

Brightness ................... 50%

Carry out the adjustments in the following order :3-1. Beam Landing.3-2. Convergence.3-3. Focus.3-4. White Balance.

Note : Test equipment required.1. Color bar/pattern generator.2. Degausser.3. Oscilloscope.4. Digital multimeter.

Caution :

High voltages are present on the Deflection yoke terminals- take care when handling the Deflection yoke whilst carryingout adjustments.

4. If the V.STAT magnet is moved in the direction of the (a)and (b) arrows, the Red, Green and Blue points move as

indicated below.

1. [Moving horizontally], adjust the H.STAT control so thatthe Red, Green and Blue points are on top of each other atthe centre of the screen.

2. [Moving vertically], adjust the V.STAT magnet so that theRed, Green and Blue points are on top of each other at thecentre of the screen.

3. If the H.STAT variable resistor is unable to bring the Red,Green and Blue points together at the centre of the screen,adjust the horizontal convergence with the H.STAT variableresistor and the V.STAT magnet in the manner indicatedbelow.[In this case, the H.STAT variable resistor and the V.STATmagnet influence each other].

The movement of the magnets interact with each other and sothe respective dot position should be monitored while carryingout this adjustment.Use the H.STAT VR to adjust the Red, Green and Blue dots sothat they coincide at the centre of the screen(by moving the dots in the horizontal direction).

Printed in U.K.© 2001.4

A new TV Repair Assistance Tool that combines ease of use and powerful PC software tools toallow you to save valuable time during many TV repairs.

The TRACE interface connects to the PC's serial port. It providesconnection to the TV's I2C bus and can be provided with an InfraRedtransmitter (optional).

The interface is powered by a standard 9 V PP3 battery for portableuse, and can also be powered by an external 9V/25mA DC powersupply.

The TRACE software that is supplied with the interface allows you to:

With the optional IR Add-on kit, the following features can be added:

Additional features such as Adjustments and Troubleshooting areavailable in chassis-dependent software modules. Please contact yourlocal Sony Service organisation for the latest information.

•••

Read, restore and compare NVM contents via the I2C busAcknowledge check of all I2C devices in the TV setRead Error Codes (emulation of the Error Reader tool)

Remote Commander emulationUser programmable Functional Check through InfraredFast and documented Test Mode setting of all Sony TV chassis

•••

Partnumbers: TRACE Starter Kit (TRACE interface + software): 9-948-320-70TRACE Software (for users of the I2C Link interface): 9-948-340-80TRACE IR Add-on (IR interface + Remote Commander software): 9-948-320-80

PC requirements: IBM-compatible PC with operating system Windows95, Windows98, or WindowsNT*.

* WindowsNT only supported with TRACE interface

Note: For workshops already using the existing I2C Link parallel port interface (9-948-320-30), this software can be used as well, replacing theTV Data Handling software (9-948-340-50), but Error Reader and IR functions can only be accessed with the TRACE interface.
