[9] Initialization to factory settings
[10] Lamp error detection
1. Function 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 following 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.)
2. Countermeasures
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 “L ERROR RESET” on point 7, page 10/11 of the adjustment process is 1 or more. If it is 1 or more, it indicates the lamp error detec-
tion was executed. After confirming that the lamp or lamp circuit is normal, reset the lamp error counter pushing “OK” in the R/C. After resetting
counter the label “***OK***” appears on Screen.
3. Reset standby cause error list
