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.

Problem
Picture slanted
Noisy picture when viewing
a TV channel.
Remote control does not
function.
The standby indicator on
the TV flashes.
Solution
• Using the menu system, select the “Picture Rotation” option
in the “Detail Set Up” menu to correct the picture slant (see
page 16).
• Using the menu system, select the “Manual Programme
Preset” menu and adjust Fine Tuning (AFT) to obtain better
picture reception (see page 15).
• Using the menu system, select the “Noise Reduction” option
in the “Picture Adjustment” menu and select “Auto” to
reduce the noise in the picture (see page 19).
• Check that the Media Selector on the remote control is set to
the device you are using (VCR, TV or DVD).
• If the remote control does not operate the VCR or DVD even
when the Media Selector has been set correctly. Enter the
necessary code set as explained in the “Remote Control
Configuration for VCR/DVD” chapter of this instruction
manual (see page 22).
• Replace the batteries.

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.
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 :
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.
