Question about LG Televison & Video
You most likely have a week capacitor on the power board. When the TV warms up the cap stops working. Check for bulged or leaking caps and replace them.

Sounds like a overheating issue. Try facing a large fan blowing across the back of the unit and see if this changes anything. If it does, it might help to blow the back out with compressed air as dust might be helping it overheat.

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!
