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-2D SELF DIAGNOSTIC SOFTWARE

The identification of errors within the FE-2D 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.

the familiar information that analogue (conventional) text services provide but with

the look and feel of a graphically rich website.

The appearance, content and navigation methods of all digital text services are

decided by the broadcaster. For example, digital text from the BBC may look

different from digital text from ITV. Most of the digital text services currently

available use simple navigation methods based on the following buttons:

Viewing digital text

There are two ways to view digital text, either while watching a digital channel or by

accessing a dedicated digital text channel.

SECTION 2 DISASSEMBLY

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).

Fig.3-5

• Tilt the V.STAT magnet and adjust the static convergence by

opening or closing the V.STAT magnet.

Tilt Direction

If you are unable to adjust the corner convergence properly,
this can be corrected with the use of permalloy magnets.

HTIL correction can be performed by adding

one TLH

correction assembly to the Deflection yoke.

HTIL Adjustment

YCH Adjustment

TLV Adjustment

Geometry Adjustment.

Preparation:

Before starting this adjustment, adjust the horizontal and
vertical static convergence.

1. Remove the deflection yoke spacer.

2. Tilt the deflection yoke as indicated in the figure below and

optimise the geometry.
Tilting the DY Up and Down a small amount will balance
the upper and lower pin adjustment.

3. Re-install the deflection yoke spacers. Ensure 4 DY spacers are

reinserted

4. The H-Trap and T-B Pin may not achieve a good level due
to a small tilt allowance on the square DY. Keep the DY in
a straight position and adjust H-Trap pot (See diagram for
HTIL Adjustment) and Y-Mg for T-B Pin, as below.

• APH Convergence parameter is electrically controlled. For this
reason a TLH piece may not be required.
