SECTION 1
SELF DIAGNOSIS FUNCTION
The unit in this manual contain a self-diagnostic function. If any 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.
1-1. DIAGNOSTIC TEST INDICATORS
When any 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.
Result for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

Unless the result display is cleared to “0”, the self-diagnostic function will not be able to detect subsequent faults after comple-
tion of the repairs.
[Clearing the result display]
To clear the result display to “0”, press button on the remote commander sequentially as shown below when the diagnostic
screen is being displayed.
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

1-6. SELF-DIAGNOSTIC CIRCUIT
+B overcurrent (OCP) Occurs when an overcurrent on the +B (135 V) line is detected by
Q6504.
Then the voltage to pin 5 of IC001 goes UP. The unit will automatically
turn off.
+B overvoltage (OVP) Occurs when an overvoltage on the +B (135 V) line is detected by
IC6502.
Then the voltage to pin 8 of IC001 goes UP. The unit will automatically
turn off.
Vertical deflection failure Occurs when an absence of the vertical deflection pulse is detected by
Q8001 and D8001. Shut down the power supply.
White balance failure If the RGB levels do not balance or become low level within 5 seconds.
This error will be detected by IC4300.
TV will stay on, but there will be no picture.
High voltage or Horizontal Deflection Protect Occurs when an overvoltage of horizontal pulse is detected by D8038
and IC8006.
If the voltage of pin 1 of IC8006 goes to High, the voltage to pin 57 of
IC4300go to UP. The unit will automatically turn off.
Audio Protector If the Audio out lines become DC.This error will be detected by Q1211,
Q1209 and Q1210.
The unit will automatically turn off.

KG or KB of CR board, CG board and CB board.(Fig.3-2)
3. Adjust red, green and blue screen voltage to until retrace
line disappears with screen VR on the focus pack.
4. Supply DC 172 ± 0.5 V from external power supply to KR,
KG or KB of CR board, CG board and CB board.(Fig.3-3)
5. Confirm if retrance can be seen.
