Plasma tv takes time to start then picture flickers really badly then picture returns as normaal for a few hours then goes black but still has sound i turn off tv for a number of hours & repeat the same process to get tv to work again any idea what the problem could be

This tv seem to have two problems.The problems that the tv take a long time the tv to turn on,the tv power supply board have dying capacitors most likely.That the board where the power a/c cord plug into it.The picture flickers badly this problems is harder to determine because this causes by two backlight buffers boards X,Z buffers boards could be either one it is dying.This tv should get an estamate by a shop or shops and repair it by them,bcause the tv must have to be doing replacing x munbers capacitors components to the tv power supply board and alot more work to trouble shoot and to detrmine which of the buffers boards it is the causes of to the picture screen to be badly flickers and replacing it.

32'' LG Plasma has a problem turning on,the infra red light turns green to red several times before the picture comes on ,any solutions . Tony
