Whenever the power goes out, or if I have it hooked to computer and computer screen goes to sleep-when tv comes back on it will blink. It does not power off but just to sleep with computer and when I click on laptop the tv will wake up but now it blinks. I do not mean flickering but the screen will blink black then can see show then screen turns black, there is no interruption in the audio.

I was reading another thread about a different Samsung model and there was a known issue with that model and there was a jumper wire that missed getting cut at the manufacturer. I couldn't find anything about this model or what wire might need to be cut if that would fix my problem.

Last time this happen it took about 2 weeks to fix itself, it use to be alot shorter timeframe and strange as this sounds but seemed to fix quicker if if I turned the portable heater so it was facing the tv. That doesn't seem to work as good now.
