CAUTION
These  servicing  instructions  are  for  use  by  qualified  service
personnel only.
To reduce the risk of electric shock, do not perform any servicing
other than that contained in the operating instructions unless you
are qualified to do so.
WARNING!!
An  isolation  transformer  should  be  used  during  any  service  to
avoid possible shock hazard, because of live chassis.
The chassis of this receiver is directly connected to the ac power
line.

SAFETY-RELATED COMPONENT
WARNING!!
Replace  all  components  with  Sony  parts  whose  part  numbers
appear as shown in this manual or in supplements
published by Sony.
WARNINGS AND CAUTIONS
SAFETY-RELATED COMPONENT
WARNING
It is essential that all critical parts be replaced only with the part
number  specified  in  the  electrical  parts  list  to  prevent  electric
shock, fire, or other hazard.
NOTE: Do  not  modify  the  original  design  without  obtaining
written  permission  from  the  manufacturer  or  you  will
void the original parts and labor guarantee.
USE CAUTION WHEN HANDLING THE LCD PANEL
When  repairing  the  LCD  panel,  be  sure  you  are  grounded  by
using a wrist band.
When repairing the LCD panel on the wall, the LCD panel must
be secured using the 4 mounting holes on the rear cover.
1) Do not press on the panel or frame edge to avoid the risk of
electric shock.
2) Do not scratch or press on the panel with any sharp objects.
3) Do not leave the module in high temperatures or in areas of
high humidity for an extended period of time.
4) Do not expose the LCD panel to direct sunlight.
5) Avoid contact with water. It may cause a short circuit within
the module.
6) Disconnect the AC power when replacing the backlight (CCFL)
or inverter circuit.
(High voltage occurs at the inverter circuit at 650Vrms.)
7) Always clean the LCD panel with a soft cloth material.
8) Use care when handling the wires or connectors of the inverter
circuit. Damaging the wires may cause a short.
9) Protect the panel from ESD to avoid damaging the electronic
circuit (C-MOS).

SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly
soldered connections. Check the entire board surface for
solder splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
leakage. Check leakage as described below.
Leakage Test
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part
having a return to chassis, must not exceed 0.5 mA (500
microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
use these instructions.
2. A battery-operated AC milliampmeter. The Data Precision
245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit”
indication is 0.75 V, so analog meters must have an accurate
low voltage scale.
The Simpson’s 250 and Sanwa SH-63TRD are examples of
passive VOMs that are suitable. Nearly all battery-operated
digital multimeters that have a 2 VAC range are suitable (see
Figure A).
How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-plate
retaining screw on most AC outlet boxes is also at earth ground.
If the retaining screw is to be used as your earth ground, verify
that it is at ground by measuring the resistance between it and a
cold-water pipe with an ohmmeter. The reading should be zero
ohms.
If a cold-water pipe is not accessible, connect a 60- to 100-watt
trouble- light (not a neon lamp) between the hot side of the
receptacle and the retaining screw. Try both slots, if necessary,
to locate the hot side on the line; the lamp should light at normal
brilliance if the screw is at ground potential (see Figure B).

The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED will automatically begin to flash.
The number of times the LED flashes translates to a probable source of the problem.
A definition of the STANDBY LED flash indicators is listed in the instruction manual for the user’s knowledge and reference.
If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to
reveal past problems and how often these problems occur.
1-1. DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY LED will flash a set number of times to indicate the possible cause of the problem.
If there is more than one error, the LED will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen.
If the screen displays a “0”, no error has occurred .

1-4. SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to
bring up past occurrences of failure for confirmation on the screen.
1-4-1. To Bring Up Screen Test
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen
After you have completed the repairs, clear the result display to “0”.
1-5. Quitting Self-diagnostic screen
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
