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

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

WARNINGS AND CAUTIONS
SELF-DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automatically begin to
flash. The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER lamp
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. DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem. If there
is more than one error, the lamp will identify the first of the problem areas.
Results for all of the following diagnostic items are displayed on screen. No error has occured if the the screen displays a "0" .
Note 1: If a +B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously.
The symptom that is diagnosed first by the microcontroller is displayed on the screen.
Note 2: Refer to Screen (G2) Adjustment in Section 3-4 of this manual.
Note 3: If standby lamp flashes 6 times, unplug unit and wait ten seconds before performing adjustment.

2. DISPLAY OF STANDBY/TIMER LIGHT FLASH COUNT
* One flash count is not used for self-diagnostic.
3. STOPPING THE STANDBY/TIMER FLASH
Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER lamp from flashing.
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 pos sible to bring up
past occurances of failure for confirmation on the screen:
[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:
Screen display
channel 5
Sound volume
Power ON
Note that this differs from entering the service mode (sound volume + ).
Self-Diagnostic screen display
5. 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 as shown below when the diagnostic screen is being
displayed.
Channel 8
ENTER
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
