Help diagnosing 52-inch LCD problem

by divamac - 6/18/09 9:17 PM

I've documented an ongoing problem with my Samsung 52" LCD. I've had it about 18 months;about 4 months ago (of course, started happening after the warranty expires) it occasionally gave me static + sound when I turned it on. I would have to turn it off then on again and it would be OK. It started happening more often, often requiring that I turn it off and on several times in order to work. Today, I cannot get a picture no matter how many times I turn it off and on.

This is not the same problem I've seen with the 46" models (no picture, but has sound). This is a violent static + good sound. Link to a video of the problem is below. Any advice greatly appreciated. BTW, I've been contacting Samsung for service for 34 days and no response. Nice. Note, I don't know the exact model number offhand - the model number on the video may not be correct.

I have TimeWarner cable, connected through HDMI. The HDMI connection from the cable box has been a problem (lots of documentation online of bad HD cable boxes). Could the bad HDMI signal from the cable box have shorted out something in the TV?
