(Thought I'd make a new thread to avoid derailing the original.)

This is an issue with the same Samsung HLN437W TV as before. Recently, the screen has been locking up in a weird, all black and white (two-tone, not grayscale!) screen. Sound and controls still work, and the only way to fix the problem is to restart the TV. I have been unable to figure out anything I or the set have been doing that might trigger it. Some days the set will run for hours and hours with no problems at all; tonight, the screen froze before it was running for five minutes.

Attached is a photo of the condition.
