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.

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

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

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

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

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.

3-1. Beam Landing

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]

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. [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].

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

opening or closing the V.STAT magnet.

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).
