The circuit boards listed below [Table 1] used in these models may
have been processed using Lead Free Solder. The boards are
identified by the LF logo located close to the board designation e.g.
F1, H1 etc [ see examples ]. The servicing of these boards requires
special precautions to be taken as outlined below.
Table 1
CAUTION
Lead Free Soldered Boards
example 1
example 2
It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder is
available under the following part numbers :
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires
soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
For more information on the use of Lead Free Solder, please refer to http://www.sony-training.com

How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.
FUSE
WARNING (UK Models only)
The flexible mains lead is supplied connected to a B.S. 1363 fused
plug having a fuse of 5 AMP rating. Should the fuse need to be
replaced, use a 5AMP FUSE approved by ASTA to BS 1362, ie one
that carries the
ASA
T
mark.
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD
BE CUT OFF AND AN APPROPRIATE PLUG FITTED. THE PLUG
SEVERED FROM THE MAINS LEAD MUST BE DESTROYED AS A
PLUG WITH BARED WIRES IS DANGEROUS IF ENGAGED IN A
LIVE SOCKET.
When an alternative type of plug is used, it should be fitted with a
5 AMP FUSE, otherwise the circuit should be protected by a 5AMP
FUSE at the distribution board.

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 event
of 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 flashing
LED) 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 number
will 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

14:9: Compromise between 4:3 and 16:9 pict ure size.
Zoom: W idescreen format for letterbox movies.
Wide: For 16:9 broadcast. Full picture information.
Note: In “Smart”, “Zoom” and “14:9” modes, parts of the top and bottom of the
screen are cut off. Press
or to adjust the position of the image on the screen
(e.g. to read subtitles).

AV2 OUTPUT
The “AV2 Output” option in the “Detail Set Up” menu allows you to select the
source to be output from the Scart connector
2/
in order you can
record from this Scart any signal coming from the TV or from external
equipment connected to the Scart connector
1/
or front connectors
3 and 3.
If your VCR supports SmartLink, this procedure is not necessary.
To do this: after selecting the option, press . Then press or to select
the desired output signal: TV, AV1, AV3 or AUTO.
Notes:
If you select “AUTO”, the output signal will alw ays be the same one that is displayed
on the screen.
If you have connected a decoder to the scart connector
2/
or to a VCR
connected to this scar t, please remember to change back the “ AV2 Output” to
“AUTO” or “TV” for correct unscrambling.
RGB CENTRING
When connecting an RGB source, such as a “PlayStation”, you may need to
readjust the horizontal position of the picture. In that case, you can readjust
it through the “RGB Centring” option in the “Detail Set Up”.
To do this: while watching an RGB source select the “RGB Centring” option
and press . Then press or to adjust the centre of the picture
between –10 and +10. Finally press OK to confirm and store.
PICTURE ROTATION
Because of the earth’s magnetism, the picture may slant. In this case, you
can correct the picture slant by using the option “Picture Rotation” in the
“Detail Set Up” menu.
To do this: after selecting the option, press . Then press or to
correct any slant of the picture between -5 and +5 and finally press OK to
store.

To remove lift the main bracket rear slightly and slide the
chassis away from the beznet. Ensure that the interconnecting
leads are released from their purse locks to prevent damage
being caused.
When refitting the chassis ensure that the main
bracket is located in the beznet guide slots before
sliding the chassis forwards. Refit the
interconnecting leads in their respective purse locks.

How to handle the Anode-Cap
1. To prevent damaging the surface of the anode-cap do not use
sharp materials.
2. Do not apply too great a pressure on the rubber, as this may cause
damage to the anode connector.
3. A metal fitting called a shatter hook terminal is fitted inside the
rubber cap.
4. Do not turn the rubber foot over excessively, this may cause
damage if the shatter hook sticks out.

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET
BOTTOM PLATES.
(1) REMOVING THE PLATES
In the event of servicing being required to the solder side of the A Board printed wiring board, the
bottom plates fitted to the main chassis bracket require to be removed.
This is performed by cutting the gates with a sharp wire cutter at the locations indicated by the
arrows.
Note : There are 2 plates fitted to the main bracket.
Only remove the necessary plate to gain access to the printed wiring board.
(2) REFITTING THE PLATES
Because the plates differ in size it is important that the correct plates are refitted in their original
location.
Please note that the plates need to be rotated 180 degrees from their cut position to allow the tabs to
be fitted into their catch positions.
For safety reasons, on no account should the plates be re-
moved and not refitted after servicing.

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 the
Contrast 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 Blue
and Green take up equally sized areas on each side of the
screen. [See Fig.3-1 - 3-3].
4. Move the deflection yoke backwards and adjust so that the
entire screen becomes Red. [See Fig.3-1]
5. Switch the raster signal to Blue, then to Green and verify
the condition.
6. When the position of the deflection yoke has been
determined, fasten the deflection yoke with the screws.
7. If the beam does not land correctly in all the corners, use a
magnet to correct it. [See Fig.3-4]
• When complete readjustment is necessary or a new picture
tube is installed, carry out the following adjustments.
• Unless there are specific instructions to the contrary, carry
out these adjustments with the rated power supply.
• Unless there are specific instructions to the contrary, set the
controls 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 carrying
out 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 that
the Red, Green and Blue points are on top of each other at
the centre of the screen.
2. [Moving vertically], adjust the V.STAT magnet so that the
Red, Green and Blue points are on top of each other at the
centre 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 variable
resistor and the V.STAT magnet in the manner indicated
below.
[In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other].
The movement of the magnets interact with each other and so
the respective dot position should be monitored while carrying
out this adjustment.
Use the H.STAT VR to adjust the Red, Green and Blue dots so
that they coincide at the centre of the screen
(by moving the dots in the horizontal direction).
