Hello, I have the exact same problem that everybody here has. TV screen is black, good sound. If you turn it off and back on you get picture for a split second. I paid alot of money for this TV and now I have to replace it after 2 years. I had my old TV for many years and it still works as it always did. I am going to have to replace it and I will NOT ever buy Samsung again. EVER. I would be happy to join a class action suit. And in reading this forum it is very apparent that the Samsung rep on here is working hard to cover up the issue and point fingers at everything but the TV itself. Come on Samsung!
