8. Lamp error detection
8-1. Functional description
This LCD color 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.)
8-2. Countermeasures
8-2-1. 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 4, page 1 of the adjustment process is 1 or more. If it is 1 or
more, it indicates the lamp error detection was executed.
8-2-2. 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 4, page 1 of the adjustment process and set the number to 0 using the "VOL (+)/(–)"
keys.
