Question about LG Televison & Video

1 Answer

What is most likely cause of an LG 60PA6550 plasma TV shutting itself off (standby light comes on)after anywhere from 15 minutes to 2 hours after powering up?

Wait just a few (3-5) minutes to try powering up again and may get sound only and then picture comes back a few minutes after that. Wait for an hour or so to power back up, comes on with good picture and sound but may auto power off again around an hour later. Runs longer with back off and pretty much non-stop with a large fan blowing on the center of the exposed back.

The light is blinking a code. The code will be a series of blinks, a pause and the blinks again. Phone Sony service and give them this code. They will be able to advise you as to the problem.

Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the case..you have the above problem!

Picture goes off


A temporary solution is to unplug the TV for a few minutes, remove static from the glass with your hand. It is important to unplug rather than turn off. If you have a degauss button you can also press that before unplugging. Wait several minutes or an hour. Then plug it back in. If you have Picture in Picture it may be an issue with that and to permanently solve may need a repair person. The unplugging may get you by for a few days at a time. That's at least better than an hour.
