10. 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.
i)
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 250 ms and OFF for 1 sec).
ii)
If the above phenomenon i) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).
2. Measures
i)
Checking with lamp error detection OFF
Enter the adjustment process mode, referring to "3. 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.)
