1. Function description
This LCD colour television has a function (lamp error detection) to be turned OFF automatically for safety when the lamp or lamp circuit is abnormal.
If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed, the following occur.
1- The main unit of television is turned OFF 5 seconds after it is turned ON. (The power LED on the front side of TV turns from green to red.)
2 - If the situation “1” happens 5 times sequentially, the power is turned on (relay is turned ON).
However, the backlight is not turned on, and then the relay is turned OFF after 5 to 6 seconds. (The power LED turns from green to red.)
