It could be a stuck button on the set. check to make sure they all feel the same.. If one don't feel right try to free it .. If a button is stuck it wont let any of the others work or the remote.

This unit needs to be tested in a service center because it has problems with the operation of the video card. This could be caused by a loss of voltage supplying the video card from the power supply card. Or a failure on the video card itself. You can purchase parts for unit from Best Buy Parts at !-888-237-8289 and get customer service at 1-877-467-8289. You should get an estimate from the service center, That should tell you which parts are bad and then you can proceed from there. If the prices seem too high for parts and labor from the service center, try buying the parts yourself and have them install them for you. You should try to check the prices on the parts , just to make sure you are getting a fair deal.You can do this by getting the part numbers, you should ask the service center to provide the part numbers needed if they need to replace the power supply board or video board and with your model number of television check out the prices and availability at the Best Buy Parts website.Of course if the television is still under warranty send it in for warranty service. Hope this helps you with your problem.

I received no replies to my request. I guest I stumped 2 million techs. I'll just buy a new TV with a 5 yr warranty. No thanks to joining your service, I can do bad all by myself.
