Question about LG 37LG30 37 in. LCD HDTV

1 Answer

My 37" LG LCD TV will not turn on and it has a flashing red light on the front at the bottom. I cannot get onto LG's website and there is nothing in the manual that addresses this problem. Any suggestions??

    After checking the second paragraph below, pull the plug, wait at least 15 seconds, then plug it in and see if it will turn on. Sometimes this clears out a "soft error" and the set works again. Other times the set will work for a while, then the problem will show up again.

    The flashing light indicates something has failed in the set. Many models incorporate an error code in the light, like the "Check Engine" code in ODB I automobiles. Does it blink several times, pause and blink again? If so, how may flashes between pauses before the pattern repeats itself?

    Post back with the results and we'll try it from there.

    It still will not turn on after being unplugged. The red flashing light is continuous as long as the set is plugged in. When I unplugged it, it continued to flash for a few seconds and then stopped. Does this help??

Two possibilities: the better one is that some joker put the set in demo mode (which includes a flashing power light), then turned on the Key Lock feature and turned off the set.

To check for this (quoted from page 118 of the manual):
