6. Special features
6.1. NORMAL STANDBY CAUSE (Page 1/30)
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 fi nding a problem when you repair the troubled set.
The cause of the last standby is recorded in EEPROM whenever it is possible.
Checking this code will be useful in fi nding a problem when you repair the troubled set.
6.2. EEP SAVE (Page 30/30)
Storage of EEP adjustment value.
6.3. EEP RECOVER (Page 30/30)
Retrieval of EEP adjustment value from storage area.
6.4. MONITOR ERR CAUSE (Page 1/30)
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 fi nding a problem when you repair the troubled set.
c
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)”.
d
The character depends on the way how to acquire Time Information.
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
In the case that Time information cannot be acquired, “B” is displayed
.
Example) In this example, it is shown that the error occurred 3 times.
1) 16 T07/01/01 12:03
Error code: 16 (lamp error)
It is latest Error.
Time : 07/01/01 12:03
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)
It is Error that happens ahead of “1)”.
Time : 07/01/01 04:07
Time is acquired from analogue broadcasting.
3) 16 B00000004:11
Error code: 16 (lamp error)
It is Error that happens ahead of “2)”.
Accumulation time : It is displayed that 4:11 have passed after Backlight driving.
4) 00 000000000No error (“00” shows that the error is not occurred.)
7. Lamp Error detection
7.1. Function
This LCD color TV set incorporates a Lamp error detection feature that automatically turns off the power for safety
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 fl ash 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 fl ashing on/off.)
7.2. 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 IC2002 ] is “High” by a trouble with the lamp and lamp
If Lamp Error detection pin [22pin of PD : P3801 / 19pin of IC2002 ] 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”.
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 “P (
s
)” keys on the set at once, plug in the AC power cord to turn on
the power.
After a central icon fl ash off, separate the fi ngers 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) Reseting the lamp error count
After the lamp and lamp circuit are improved from a trouble, reset 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)
1) Enter the adjustment process mode, referring to “2. Entering and exiting the adjustment process mode.”
2) Using the cursor (▲/▼) key, move to the cursor to [LAMP ERROR RESET], line 8 on adjustment process mode
2) Using the cursor (▲/▼) key, move to the cursor to [LAMP ERROR RESET], line 8 on adjustment process mode
service page 2.
3) 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.
8. Public Mode
8.1. 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 Password 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
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 Password is judged.
c) Check the Password by inputting three digits.
If the Password “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.
In another case, the screen is erased, and it operates in the ordinary mode.
