samsung picture problem

[Davezeek]

Hi
I have a samsung plasma 50' PS50c96hd about 5 years old and just lately after the tv has been on for about 2 hours or so the picture goes off and on intermittently, but I still have sound. I have checked for loses cables etc, and all looks fine in that regard.
I was wondering if would be some kind of heat related problem, any advice would be great

Regards

Dave

Tab bonds possibly, try taking each top corner of the set in your hands and gently flexing the tv while switched on... does it reproduce the fault?

Re: samsung picture problem

Personally I wouldn't try to flex a plasma, glass is inherently brittle so you could end up cracking the screen. To me this sounds like Y-sus board issue, I've fixed a similar issue before by changing some bad diodes but I'm certainly not qualified to give good advice so I'd wait till someone comes along who know's their stuff, Tom66 is a good example.

I meant very gently... I have done it many times without ever breaking a panel

The warming up period is what makes me think panel... bonds warm and break contact.

Tom66 is one to listen to mindya, knows his stuff!

Re: samsung picture problem

First off lets get rid of some confusion. this us a plasma tv the op has. Is there still sound when this happens? You said it does so im thinking possible sustain board issue or control board. Going to have to take the back cover off for testing.
