Lamp
Error detection
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 reason, the following will result.
1) The power is interrupted in about 500ms after it is turned on.
(A central icon on the front of the TV flash on and off.: ON for 400ms and OFF for 1600ms.)
2) If the above phenomenon 1) occurs 5 times, it becomes impossible to turn on the power.
(A central icon keep flashing on/off.)
Measures
1) Set the lamp error detection to OFF
Enter the adjustment process mode, referring to “2. Entering and exiting the adjustment process mode”. The adjustment process mode can ignore “5 times count”, so If the above phenomenon 1) occurs 1~4 times, the lamp will go out. If Lamp Error detection pin [4pin of PD: P9602/19pin of IC2001] is “High” by a trouble with the lamp and lamp circuit, it can boot-up by the adjustment process mode.
Please execute “Lamp Error detection off-mode”.
Unplug the AC power cord of running TV set to force off the power.
While holding down the “VOL (-)” and “CH (UP )” keys on the set at once, touch the power supply key on the set.
After a central icon flash off, separate the fingers from key on the set.
Then, you can check the operation to see if the lamp and lamp circuit are in trouble. If you fail boot-up, retry the procedure.
Resetting the lamp error count
After the lamp and lamp circuit are improved from a trouble, reset the lamp error count.
(Because the power cannot be turned on, if a lamp error is detected 5 consecutive times.)
a) Enter the adjustment process mode,
b) Using the cursor ( UP/DOWN ) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/20.
c) With the cursor ( LEFT/ RIGHT) keys, select the [LAMP ERROR RESET] value.
Finally press the cursor (OK)., the count is reset.
Check LAMP ERROR Count on adjustment process mode Page 2/20.

Operation
procedure
# The initial input position is the digit at the left end.
# For the numeric keys “0” to “9” of R/C, key input is accepted.
Input of the other keys is prohibited.
# Change “—” to “ ” by inputting the numeric key at the input position, and shift the input position rightward one digit.
# When three digits are completely input, the Pass Word is judged.
c) Check the Pass Word by inputting three digits.
If the Pass Word “3” “6” “9”, it shifts to the Copy Mode setting screen.
In another case, the screen is erased, and it operates in the ordinary mode.
2. Exiting the Copy Mode Setting screen
There is following way to exit the Copy Mode setting screen.
# Turn off the power. (Unplug the AC power cord from the outlet to forcibly turn off the power.)
