SECTION 1
SELF DIAGNOSIS FUNCTION
The unit 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.
1-1. DIAGNOSTIC TEST INDICATORS
When an errors 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”.

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:

1-5. 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 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.
Press “

(It will indicate “CLEAR” on the screen.)
Press “

+B overcurrent (OCP)
Occurs when an overcurrent on the +B (135 V) line is detected by Q6303.
If Q6303 go to ON, the voltage to pin 3 of IC002 go to UP. The unit will
automatically turn off.
+B overvoltage (OVP)
Occurs when an overvoltage on the +B (135 V) line is detected by D6318.
If D6318 go to ON, then voltage to pin 6 of IC002 go to UP. The unit will
automatically turn off.
Vertical deflection failure
Occurs when an absence of the vertical deflection pulse is detected by
Q5302, Q5303, and D5303. 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 IC4301.
TV will stay on, but there will be no picture.
High voltage protector of Horizontal Deflection
Occurs when an overvoltage of horizontal pulse is detected by D5115 and
IC5201.
If the voltage of pin 1 of IC5201 goes to High, the voltage to pin 20 of IC4301
go to UP. The unit will automatically turn off.
Audio Protector
If the Audio out lines become DC.This error will be detected by Q1202,
Q1204 and Q1203.
The unit will automatically turn off.
