Lead Free Soldered Boards

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.

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

AE-6B SELF DIAGNOSTIC SOFTWARE

The identification of errors within the AE-6B 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.

option and press . Next press

or to adjust the fine tuning between -15 and +15.

Finally press OK twice to store.

d)

Skip any unwanted programme numbers when they are selected with the PROG +/-

buttons.

Remote Control Configuration for VCR/DVD

In it’s default condition this remote control will operate the basic functions of this Sony TV, Sony
DVDs and most Sony VCRs. To control VCRs and DVDs of other manufacturers (and some Sony
VCR models), please complete the following steps:

Before you start, look up the 3 digit code for your brand of DVD or VCR from the list

below. On those brands that have more than one code, enter the first code number.

1

Press the Media Selector button on the remote control repeatedly until the
required green light (VCR or DVD) is lit.

If Media Selector is on TV position, code numbers will not be stored.

2

Before the green light goes out, press and hold the yellow button for
approximately 6 seconds until the green light starts flashing.

3

Whilst the green light is flashing, enter all three digits of the code for your
brand of VCR or DVD using the number buttons on the remote control.

If your selected code is entered correctly, all three green lights will be lit

momentarily.

4

Turn on your VCR or DVD and check that the main functions work.

• If your device is not working or some of the functions do not work
please check that you entered the correct code set or try the next code
listed against the brand.

• Your brand codes may be lost if weak batteries are not replaced within
a few minutes. To reset your brand of DVD or VCR please repeat the
above steps. A small label is added inside the battery door to allow you
to record your brand codes.

• Not all brands are covered and not all models of every brand may be
covered.

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.

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET
BOTTOM PLATES.

For safety reasons, on no account should the plates be removed
and not refitted after servicing.

(1) REMOVING THE PLATES

In the event of servicing being required to the solder side of the printed wiring boards, 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.

- 17 -

(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.

SECTION 3 SET-UP ADJUSTMENTS

• 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 .................................. normal

Brightness .................................. normal

3-1. Beam Landing

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 TV set’s power and degauss with a degausser.

(1) Adjustment of Correction Magnet for Y-Splitting Axis.

1. Input a crosshatch signal from the pattern generator.

2. Set the Picture control to minimum and confirm that the
Brightness control is set to normal.

3. Position the neck assembly as indicated in Fig.3-2.

4. Loosen the deflection yoke fixing screw.

5. Move the deflection yoke as far forward as is possible.

6. Adjust the upper and lower pin symmetrically by opening or
closing the Y-splitting axis correction magnets located on the
neck assembly. [See Fig 3-3]

7. Return the deflection yoke to its original position and re-tighten
its fixing screw.

Fig.3-1

Y-splitting axis correction magnet

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.

(2) Landing

Note : Before carrying out the following adjustments adjust the

magnets as indicated [See Fig.3-4].

1. Input a crosshatch signal from the signal generator.

2. Rough-adjust the focus and horizontal convergence.

3. Switch from the crosshatch pattern to an all-red pattern.

4. Move the deflection yoke backwards and adjust with the purity
magnet so that the red is at the centre and it aligns
symmetrically [See Fig.3-5].

5. Move the deflection yoke forward to the point where the entire
screen just becomes red [Mark its position].

6. Move the deflection yoke further forward until the screen just
changes colour at the edges. [Mark its position]

7. Position the deflection yoke between the two marks indicated
above.

8. Input a crosshatch pattern from the pattern generator and rotate
the deflection yoke so that the horizontal lines are parallel with
the top and bottom of the screen.

9. When the position of the deflection yoke has been determined,
fasten it with its fixing screw.

10. Switch the pattern generator to green then blue and confirm the
purity.

11. If the beam does not land correctly in all the corners of the
screen, use disk magnets to correct it. [Confirm the corner
landing forgreen and blue]

Caution :

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