Does it only happen when you?re watching broadcast television content? Or is it happening with other signals, such as DVD, Blu-Ray, games, etc?
I recently purchased a Samsung 4665F from Circuit City, 46" LCD TV. Took it home, hooked it up to HD/DVR cable box, DVD player, and Onkyo surround sound system, all via component cables. I have been having an issue on HD channels. Whenever there is a bright flash of white light in the program (scene changes mainly), the TV will flash to "Searching for signal" for about 1/2 second. The sound continues as normal, and the TV kicks back on. Any idea what could cause this, or what I can do to correct it?
