6. Special features
1. NORMAL STANDBY CAUSE (Page 1/16)
Display of a cause (code) of the last standby.
The cause of the last standby is recorded in EEPROM whenever possible.
Checking this code will be useful in finding a problem when you repair the troubled set.
2. EEP SAVE (Page 16/16)
Storage of EEP adjustment value
3. EEP RECOVER (Page 16/16)
Retrieval of EEP adjustment value from storage area.
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 6 seconds after it is turned on.
(The power LED on the front of the TV set turns red from green and keeps blinking in red: ON for 300ms and OFF for 1500ms.).
2) If the above phenomenon 1) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).
2. Measures
1) Checking with lamp error detection OFF
Enter the adjustment process mode, referring to 2. Entering and exiting the adjustment process mode.
If there is a problem with the lamp or lamp circuit, the lamp will go out. (The power LED is green.)
Then, you can check the operation to see if the lamp and lamp circuit are in trouble.
2) Resetting the lamp error count
After the lamp and lamp circuit are found out of trouble, reset the lamp error count. If a lamp error is detected five consecutive times, the power
cannot be turned on. Using the cursor (
/
) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode ser-
vice page 2/16. With the cursor (</>) keys, select the [LAMP ERROR RESET] value. Finally press the cursor (OK) eys to reset the value to “0”.
