WARNINGS AND CAUTIONS
CAUTION
Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield, or carbon painted on the CRT,
after removing the anode.
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!!
Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for
safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements
published by Sony. Circuit adjustments that are critical for safe operation are identified in this manual.Follow these procedures
whenever critical components are replaced or improper operation is suspected.
ATTENTION!!
Apres avoir deconnecte le cap de l’anode, court-circuiter l’anode du tube cathodique et celui de l’anode du cap au chassis metallique
de l’appareil, ou la couche de carbone peinte sur le tube cathodique ou au blindage du tube cathodique.
Afin d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout
dépannage.Le chássis de ce récepteur est directement raccordé à l’alimentation du secteur.

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 B+ and HV to see if they are speciÞed values. Make sure
your instruments are accurate; be suspicious of your HV meter if sets
always have low HV.
8. 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).

Stopping the STANDBY/i.LINK STANDBY LED Flash
Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/i.LINK STANDBY LAMP from flashing.
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 on the screen for confirmation.
The units in this manual contain a self-diagnostic function.If an error occurs, the STANDBY/i.LINK 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/i.LINK 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.
DiagnosticTest Indicators
When an error occurs, the STANDBY/i.LINK 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.
Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

Handling of Self-Diagnostic Screen Display
Since the diagnostic results displayed on the screen are not
automatically cleared, always check the self-diagnostic screen
during repairs. When you have completed the repairs, clear the
result display to “0”. Unless the result display is cleared to “0”, the
self-diagnostic function will not be able to detect subsequent faults after completion of the repairs.
Clearing the Result Display
To clear the result display to “0”, press buttons on the Remote Commander sequentially when the diagnostic screen is displayed, as shown below:
ENTERChannel 8
Quitting the Self-Diagnostic Screen
To quit the entire self-diagnostic screen, turn off the power switch on the Remote Commander or the main unit.
Self-Diagnostic Circuit
+B overcurrent (OCP)
Occurs when an overcurrent (more
than 6A) on the +B (135V) line
is detected by R6598/R6591.It will
cause Q6520 to turn on and force the
AC relay to turn off through Q6532
and Q6530.
+B overvoltage (OVP)
Occurs when 1) overvoltage (more
than +140V) on the +B (135V) line
is detected by IC6505, or 2) an
overvoltage (more than 7.5 V) on the
unreg 7V line is detected by D6014.
The AC relay will turn off through
Q6532 and Q6530.
Vertical Deflection Stopped
Occurs when an absence of the
Vertical deflection pulse is detected by
IC201. Power supply will shut down
when waveform interval exceeds 2
seconds.
White Balance Failure
If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC201.TV will stay on, but there
will be no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Low B OCP/OVP
Occurs when set 5V is out.
Horizontal Deflection Stopped
Occurs when either: 1) a +B overcurrent is detected (IC5007), or 2) overheating is detected (Thermistor TH5002).
To Bring Up ScreenTest
In standby mode, press buttons on the Remote Commander

**Note: Typically, adjustments will be made to this unit while it
is in its normal position in a customer’s home. Any
directional references made in this manual should only
be followed when the unit is being serviced elsewhere
(e.g. in a shop).
PROCEDURE:
1. Turn on power to the set and make sure that the degauss circuit is in
working order (a brief hum will sound from the degauss coils).
2. Loosen the deflection yoke mounting screw, and set the purity
magnet adjustment tabs to the center as shown below:
Purity Magnet Adjustment Tabs
3. Input a green raster from the pattern generator.
4. Move the deflection yoke backwards, and adjust the purity ring
magnets so that the center of the screen is green, and the red and
blue areas on either side of the screen are approximately the same
size as shown in the figure below:
Blue Red
Green
5. Move the deflection yoke forward until the entire screen becomes
green.
6. Confirm the purity for both the red and blue rasters.
7. Tighten the deflection yoke mounting screw just enough to keep the
yoke from moving forward or backward, but not too tight as to keep
it from rotating.
8. Input a crosshatch pattern from the generator. Rotate the yoke so
that the crosshatch’s top and bottom lines are as even with the
bezel as possible. Secure the deflection yoke by fully tightening the
mounting screw.
9. Use a DY Spacer (p/n: 4-053-005-01) between the deflection yoke
and the CRT in order to maintain the yoke position in each axis.
10.Add disk magnets (p/n: 1-452-032-00) to the back of the CRT as

SECTION 4. PICTURE SIZE AND GEOMETRY ADJUSTMENTS
Perform these adjustments when any of the following are replaced: CRT, deflection yoke, D-board, and whenever touch-ups are required.
REQUIRED EQUIPMENT:
NTSC generator with monoscope pattern and cross-hatch pattern. (In lieu of the monoscope pattern, the cross-hatch pattern will suffice. However,
to correctly size the picture you must be able to calculate what percentage of the generator’s full pattern is being displayed due to the over-scanning
of the CRT.)
NOTE:Throughout these adjustment procedures you will be instructed to “Write the data to memory”. To do this, follow this procedure:
1. Press the “MUTE” button (“WRITE”appears in green letters at the top right corner of the screen).
2. Press the “ENTER” button (“WRITE”changes from green to red, then “WRITE”changes to “SERVICE”).
