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

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.

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.
Check LAMP ERROR Count on adjustment process mode Page 2/20.

Public Mode
1. Starting the Public Mode
# There are two following ways to display the PUBLIC Mode setting screen.
1) Turn off the power, and turn it on again, pressing the “CHANNEL UP” and “Volume UP” keys of the main unit at the same time.
Please separate the finger from the power supply key when boot-up is confirmed with lighting of a central icon etc.
After a while, value of Enter password appears on the screen.
a) Turn off the power, refer to “3. Method of shuts down for Power supply”.
b) While holding down the “INPUT” and “Volume (+)” keys on the set at once, touch the power supply key on the set.
Please separate the finger from the power supply key when boot-up is confirmed with lighting of a central icon etc.
After a while, value of Enter password appears on the screen.
c) Display the Pass Word input screen.

2. Exiting the Public Mode Setting screen
# There are two following ways to exit the Public Mode setting screen.
1) Turn off the power.
2) Select “Execution” in the PUBLIC_Mode to execute it.
Activate the restart under the set content.
Here, the START input SOURCE setting is excluded since this item is referred to only when the power is turned on.

3. Set value of the Public Mode
# When the shipment setting is done, a set each value in Public Mode is initialized.
(PUBLIC MODE in the process mode Setting of a flag is also initialized)
# Separately, the shipment beginnings when all except for each set value in Public Mode is initialized are provided for a process mode.
(INDUSTRY INIT (-Public))
# Only when turning on the PUBLIC MODE item, each setting is effective.
# After it decides it with EXECUTE, it AC OFF/ON it to reflect a set value.
