Did you fix your problem? If so, how?

I am having the same problem and at times it tells me my lamp is bad, which I know it is not because that is new.

Any ideas?

I can hear the sound but i can only see the picture in Video mode and PIP mode..... LG model # 52sx4d-ub


dcooper1288,

You have a bad mainboard.

They are available at http://www.encompass.com and are not that difficult to replace. This is a common problem with the LG units and don't be surprised if it takes a while to get a board.

Thanks for using FixYa and for the generous rating.

Tv Turns on then stops after a few minutes


This set uses a lamp and a bad lamp will cause this symptom. You should be able to get the lamp out yourself and get a part # off it.
