CAUTION
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.
Table 1
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 SUIT-
ABLE 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.

AE-6BA SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6BA 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.
Table 1
How to enter into Table 2
1.
Turn on the main power switch of the TV set.
2.
Program Remote Commander for Operation in Service
Mode. [See Page 22].

Remote Control Configuration for VCR or 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), the
remote control needs to be configured.
Additional Information
To do this:
• 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.
• Sony will endeavour to update the software according to market changes. Therefore, please
refer to the code table included with the remote control for latest code set.
• A small label is added inside the battery door to allow you to record your brand codes.
1
Press and hold the T button of the remote control for approximately 6
seconds until the green DVD and VCR light of the Media Selector starts
flashing (see fig. 1).
2
While the VCR and DVD lights are flashing, enter all three digits of the
code for your brand of VCR or DVD (see the list below) using the number
buttons on the remote control (see fig. 2).
If your selected code is entered correctly, the VCR or DVD green
light (according to your selection) will be lit momentarily (see fig.3),
otherwise repeat all the above steps.
3
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.
• Not all brands are covered and not all models of every brand may be covered.
4 Always remember to press the T or t button until the green light iluminates according to
the equipment you want to operate with this remote control: VCR, TV or DVD.

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 of the Anode-Cap
2-8. Picture Tube Removal
WARNING:
BEFORE REMOVING

High voltage remains in the CRT even
after the power is disconnected. To
avoid electric shock, discharge CRT
before attempting to remove the anode
cap. Short between anode and CRT

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

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.
Carry out the adjustments in the following order :
3-1.
Beam Landing.
3-2.
Convergence.
3-3.
Focus.
3-4.

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.

Note :
•
All capacitors are in µF unless otherwise noted.
•
pF : µµF 50WV or less are not indicated except for
electrolytic types.
•
Indication of resistance, which does not have one for
rating electrical power, is as follows.
Pitch : 5mm
Electrical power rating : 1/4W
•
Chip resistors are 1/10W
•
All resistors are in ohms.
k = 1000 ohms, M = 1000,000 ohms
•
: nonflammable resistor.
•
: fusible resistor.
•
: internal component.
•
: panel designation or adjustment for repair.
•
All variable and adjustable resistors have
characteristic curve B, unless otherwise noted.
•
All voltages are in Volts.
•
Readings are taken with a 10Mohm digital mutimeter.
•
Readings are taken with a color bar input signal.
•
Voltage variations may be noted due to normal production
tolerences.

Note :
Portions of the circuit contained within
the marked areas as shown have high
voltages present. Use care to prevent
electric shock during inspection or repair.
An Isolation Transformer must be used
during any Service work to avoid possible
shock hazard due to live chassis. The
chassis of this receiver is directly
connected to the power line.
