5. Special features
1. NORMAL STANDBY CAUSE (Page 1/20)
Display of a cause (code) of the last standby.
The cause of the last standby is recorded in EEPROM whenever it is possible.
Checking this code will be useful in finding a problem when you repair the troubled set.

2. EEP SAVE (Page 20/20)
Storage of EEP adjustment value.
3. EEP RECOVER (Page 20/20)
Retrieval of EEP adjustment value from storage area.
4. MONITOR ERR CAUSE (Page 1/20)
Display of a cause (code) of Error from Monitor microcomputer.
The cause of Error is recorded in EEPROM whenever it is possible.
Checking this code will be useful in finding a problem when you repair the troubled set.
1) This displays Error code and time when the error occurred.
The cause of Error is recorded in EEPROM whenever it is possible.
Checking this code will be useful in finding a problem when you repair the troubled set.
1) This displays Error code and time when the error occurred.
The latest error is displayed on “1)”.
The error that happens ahead of “1)” is displayed on “2)”.
The error that happens ahead of “1)” is displayed on “2)”.
2) The character depends on the way how to acquire Time Information.
Example) In this example, it is shown that the error occurred 3 times.
T: Time is acquired from digital broadcasting
This doesn’t contain “Time offset” which is considered a time difference and Daylight-Saving Time, etc. ...
U: Time is acquired from analog broadcasting (teletext)
B: Accumulation time of Backlight
B: Accumulation time of Backlight
In the case that Time information cannot be acquired, “B” is displayed.
1) 16 T07/01/01 12:03
Error code: 16 (lamp error)
Time: 07/01/01 12:03
* It is latest Error.
* Time is acquired from digital broadcasting.
* Time is UTC which doesn't have Time offset.
* Time is acquired from digital broadcasting.
* Time is UTC which doesn't have Time offset.
2) 16 U01/01/01 04:07
Error code: 16 (lamp error)
Time: 07/01/01 04:07
* It is Error that happens ahead of “1)”.
* Time is acquired from analogue broadcasting.
* Time is acquired from analogue broadcasting.
3) 16 B00000004:11

Accumulation time: It is displayed that 4:11 have passed after Backlight driving.
* It is Error that happens ahead of “2)”.
4) 00 0000000000000
No error (“00” shows that the error is not occurred.)

6. 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 rea-
son, the following will result.
1) The power is interrupted in about 500ms after it is turned on.
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, 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
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 (
While holding down the “VOL (-)” and “CH (
)” keys on the set at once, plug in the AC power cord to turn on the power.
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, referring to “4. Entering and exiting the adjustment process mode”.
b) Using the cursor ( / ) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/20.
c) With the cursor ( / ) keys, select the [LAMP ERROR RESET] value.
