The units in this manual contain a self-diagnostic function. If an error occurs, the STANBY/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 STANBY/
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 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 occured if the screen displays a “0”.

back to normal.
• Detect Micro latch up.
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.

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 con-
firmed, it is possible 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:

5. HANDLINGOF 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] /0
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
6. SELF-DIAGNOSTIC CIRCUIT
[+BovercurrentªOCPº] Occurs when an overcurrent on the +B(135) line is detected by Q604. If Q604 go to
ON and the voltage to pin 18 of IC301 should go down when V.SYNC is more than
seven verticals in a period, the unit will automatically turn off.
[Verticaldeflectionstopped] Occurs when an absence of the vertical deflection pulse is detected by Q509 and
IC001 shut down the power supply.
[Verticaldeflectionovercurrent] Occurs when an overcurrent on V drive line is detected by Q507. Power supply will
be shut down when detect this by IC001.
[ hitebalancefailure] If the RGB levels* do not balance or become low level within 5 seconds, this error
will be detected by IC301. TV will stay on, but there will be no picture.
