SERVICE MODE AND SOFTWARE UPDATE ADJUSTMENTS
ADJUSTMENT
ADJUSTMENT PROCEDURE
Entering and exiting the adjustment process mode
1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.2) While holding down the “VOL (–)” and “INPUT” keys at a time, plug in the AC cord of the main unit to turn on the power.
The letter “<K>” appears on the screen.
3) Next, hold down the “VOL (–)” and “CH ( V )” keys at a time.
(The “VOL (–)” and “CH ( V )” keys should be pressed and held until the display appears.)
Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode. When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.
4) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)
CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the settings are tampered in this mode, unrecoverable system damage may result.

Lamp Error detection
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 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.)
2. Measures
1) Set the lamp error detection to OFF
Enter the adjustment process mode

2. Measures
1) Set the lamp error detection to OFF
Enter 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.

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.
2) 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. Entering and exiting 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.
