6. Special features
1. NORMAL STANDBY CAUSE (Page 1/21)
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 21/21)
Storage of EEP adjustment value.
3. EEP RECOVER (Page 21/21)
Retrieval of EEP adjustment value from storage area.
4. MONITOR ERR CAUSE (Page 1/21)
Display of a cause (code) of Error from Monitor microprocessor.
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)”. 
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 
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.
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.
3) 16 B00000004:11
Error code: 16 (lamp error) 
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.)

7. 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.
(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 [22pin of PD: P3801/19pin of IC2004] 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 (
)” 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.
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 “2. 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 2/21.
c) With the cursor ( / ) 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 2/21.

8. Public Mode
1. Starting the Public Mode
1)  Method of needing password
a) While holding down the  "INPUT"  and   "Volume UP"  keys on the set at once, plug in the AC power cord to turn on the power.
b) Display the Pass Word input screen.
After a while, value of Enter password appears on the screen.
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 “0” “2” “7”, it shifts to the PUBLIC Mode setting screen.
In another case, the screen is erased, and it operates in the ordinary mode.
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.
