LAMP ERROR DETECTION
This LCD color television has a function (lamp error
detection) to be turned OFF the TV set automatically for safety criteria 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 occurs:
- The TV set is turned OFF automatically 20 seconds after it is turned ON by the user. (The power LED on the front side of TV turns from green to red)
- If the situation “stated above.” happens 5 times sequentially, it becomes impossible to turn on the power. (The power LED turns from green to red and keeps blinking in red).
COUNTERMEASURES
- Checking with [L Error Check Off]. Repair the problem that produces the LAMP ERROR. The TV remains with power LED blinking until K mode is forced by local keyboard, in order to disable the LAMP ERROR detection. To disable the LAMP ERROR feature is necessary enter in K mode by pressing “VOL DOWN” and “à[ ]” keys at same time when the AC cord is plugged in.
- Resetting the LAMP ERROR counter. After the lamp and lamp circuit are found out of trouble, the LAMP ERROR counter should be reset. If a LAMP ERROR is detected five consecutive times, the power cannot be turned on.
Method 1: Using the cursor (UP/DOWN) key, move to the cursor
to [L Error Reset] on Line 6 of ETC Menu. With the cursor (LEFT/RIGHT) keys
reset the value to “0”.
Method 2: In the case the TV is not blocked (less than
5 consecutive errors), switch on the Set. After 30 minutes working, the LAMP
ERROR counter will be reset automatically.
