LN52A850 when i turn on the tv the screen is a little dark in the center and the right half side of screen is scrambled looking. after a few minutes the picture finally goes back to normal or if i tap on the back of the tv sometimes this will make it normal looking again. TV is a little over 2 years old.

It does sound a lot like a buffer board problem, Just which one is the question. Sometimes it is in fact a connection issue. But 1/2 of the screen missing sounds like maybe connection between the 2 buffer boards. It could possibly be the panel. If that is the case. ITs over for that set. But i would suggest first calling samsung and asking them to extend the warranty for 90 days or so. Sometimes they will do this for nice customer such as yourself. 1-800-SAMSUNG. Let me know how this turns out first then we can proceed further if needed. Good luck and keep me posted. Sincerely Jay

I have the same problem of the set turning off and on by itself. There is a circuit in Samsung TVs that would shut it down if a very loud noise occurs in the program being watched, but I have not noticed that correlation. My problem is solved by vacuuming the back panels of the set. They do not seem to have any significant dust on them, but I think the vacuum sucks somewhat inside of the TV and does some good with the fan that is supposed to be cooling the bulb and the mirror. It seems to work for months on end and when the problem recurrs, I vacuum again.

The first place to start is with the Main bd. The second cause would be the T-con bd. Have a trained Samsung tech troubleshoot to find out and repair the set.

The problem is most likely in the image processor area, or the backplane circuitry on the screen itself.
The service rep would be equipped to properly service your set. You should call LG to find out who in your area is able to service your set.
If the set is out of warranty it could be fairly expensive to service.
