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 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”.

Symptoms
• Power does not come on.
• No power is supplied to the

• AC power supply is faulty.
• Power does not come on.
• Load on power line is

• Power line is shorted or
power supply is stopped.
• No raster is generated.
• CRT cathode current

• Power is shut down shortly,
after this return 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.

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 possible to bring up past occurances of failure for confirmation on the screen:
[To Bring Up ScreenTest]
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 (mode volume [+]).

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] /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.
[White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.
