7-1. Functional description

This LCD colour television has a function (lamp error detection) to be turned OFF automatically for safety
when the lamp or lamp circuit is abnormal.
If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed,
the followings occur.

The main unit of television is turned OFF 5 seconds after it is turned ON. (The power LED on the front
side of TV turns from green to red.)

If the situation 

1

 happens 5 times sequentially, television can not be turned ON. (The power LED remains

red.)

7-2. Countermeasures
7-2-1. Check when turning OFF the lamp error detection

When television is turned OFF by the lamp error detection mentioned above, it enters the adjustment
process with the power LED red. Entering the adjustment process turns OFF the error detection and turns
ON TV.
This enables the operation check to detect errors in the lamp or lamp circuit.
Check whether "ERROR NO RESET" on line 3, page 1 of the adjustment process is 1 or more. If it is 1 or
more, it indicates the lamp error detection was executed.

7-2-2. Resetting of the lamp error count

After confirming that the lamp or lamp circuit is normal, reset the lamp error count. Select "ERROR NO
RESET" on line 3, page 1 of the adjustment process and set the number to 0 using the volume button.
