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.

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:

[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander
sequentially in rapid succession as shown below:

SELF DIAGNOSTIC

Self-Diagnosis is screen display:

*: Note that this differs from entering the service mode

(volume +)

Since the diagnostic results displayed on the screen are
not automatically cleared, always check the self-
diagnostic screen.

After you have completed repairs, clear the result display
to “0”

[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.

Press

 button

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

Press

 button

(The “CLEAR” display change to red color.)

[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power
switch on the remote commander or the main unit.

+B overcurrent (OCP)

Occurs when excessive current flows through R6812.
The increase in voltage across Q6803 causes it to turn on which sends a high
signal to the micro.

+B overvoltage (OVP)

IC6801 detects +B OVP condition and Q6802.
This sends a high signal to the micro and also shuts down the AC relay.

V-STOP

Occurs when an absence of the vertical deflection pulse is detected by pin 56
of IC0404. (MG board)
Power supply will shut down when waveform interval exceeds 2 seconds.

While balance failure

If the RGB levels* do not balance within 2 seconds after the power is turned
on, this error will be detected by IC0401.
TV will stay on, but there will be no picture.

Low +B OCP/OVP

Occurs when set 5V is out.

Horizontal deflection stopped

Occurs when either:
1) a +B overcurrent is detected (Q6803), or
2) IC0401 (MG board) is damaged.
