Lamp error detection
This LCD color TV set incorporates a lamp error detection feature that automatically turns off the power for safety under abnormal lamp or lamp circuit conditions. If by any chance anything is wrong with the lamp or lamp circuit or if the lamp error detection feature is activated for some reason, the following will result.
i) The power is interrupted in about 6 seconds after it is turned on.
(The power LED on the front of the TV set turns red from green and keeps blinking in red: ON for 250 ms and OFF for 1 sec). ii) If the above phenomenon i) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).
Measures
i) Checking with lamp error detection OFF
Enter the adjustment process mode, referring to "3. Entering and exiting the adjustment process mode."
If there is a problem with the lamp or lamp circuit, the lamp will go out. (The power LED is green.)
Then, you can check the operation to see if the lamp and lamp circuit are in trouble.
ii) Resetting the lamp error count
After the lamp and lamp circuit are found out of trouble, reset the lamp error count. If a lamp error is detected five consecutive times, the power cannot be turned on. Using the cursor (UP/DOWN) key, move to the cursor to [L ERR RESET], Line 6 on adjustment process mode service page 10/13. With the cursor (LEFT/RIGHT) keys, select the [L ERR RESET] value. Finally press the cursor (OK) keys to reset the value to "0". Reset to "0 "
