7. Lamp error detection
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.
1 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.)
2 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
If the power has been turned off 5 times because of lamp error, hold down the unit's "INPUT" and "Volume
(–)" kye simultaneously and turn on the unit's power switch. The TV set gets back on power in the "K"
mode.
In this state, press the unit's "Volume (–)" and "P (Ù)" key simultaneously. The Adjustment Process mode
shows up.
This enables the operation check to detect errors in the lamp or lamp circuit.
Check whether "ERROR NO RESET" 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" of the adjustment process and set the number to 0 using the "LEFT" or "RIGHT" cursor key.
