I will be watching tv or a movie and the screen will lock up but the sound will keep going then the tv shuts off and the red light blinks then it will come back on after a few minutes. It does it over and over, like it is going into some mode or having power or heat issues. I bought another one and it is hooked up exactly the same and it dosen't have a problem both are brand new.
I'm afraid this is going to be an expensive repair. The digital video board will need to be replaced. If you get service manual from www.samsungparts.com, and send me a copy, I can tell you what board is bad, but like I said, expensive. Most likely about 400 bucks or so for the digital board. Good Luck
