1. Function

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 rea-
son,  the following will result.

1) 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).

2) If the above phenomenon 1) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).

2. Measures

1) 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.

2) Resetting the lamp error count

After the lamp and lamp circuit are found out of trouble, reset the lamp error count.

Using the (UP/DOWN) key, move to the cursor to "ERROR NO RESET", line 3 on adjustment process mode service page 1.

With the (LEFT/RIGHT) keys,  select the "ERROR NO RESET" value. 

Finally press the (OK) keys to reset the value to "0".

3) Method of other resets

If a lamp error is detected five consecutive times,  the power cannot be turned on.

In this case,  while pressing "CH DOWN" key and "VOL (+)" key at the same time, MAIN power supply SW enters.

Or, Please let it blink as the above-mentioned  for three minutes or more. Then, it is reset in "0".
