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 off” that cannot be confirmed, 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:

[Screen display] / channel [5] / Sound volume [-] / Power ON

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.

[+B overcurrent ªOCPº]

Occurs when an overcurrent on the +B(135) line is detected by Q6610
and Q6609.
If Q6610 and Q6609 go to ON, the voltage to the pin3 of IC001 go to UP.
The unit will automatically turn off.

[+B overvoltage ªOVPº]

Occurs when an overvoltage on the +B(135) line is detected by D6635
and Q6611. If Q6611 go to ON, the voltage to pin6 of IC001 go to UP. The
unit will automatically turn off.

[Vertical deflection failure]

Occurs when an absence of the vertical deflection pulse is detected by
Q6819 and R6832. 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 D6809 and
IC6801.
If the voltage of anode D6830, Q6800 and D6825 goes to High, the
voltage to pin34 of IC4301 go to UP. The unit will automatically turn off.
