I think there was a thread about this a while back, but it's not there anymore, and I don't know if the issue got resolved or not. Here goes: Every once in awhile, the picture just disappears for maybe a second or so. Th tv indicates that it has no signal during that time. The sound goes on normally, no interruption. This has happened while watching a Bluray, playing a game from disc, and playing a game from hard drive (so no disc layer change!). What could be the cause of this? How do I fix it? It doesn't really happen often, but it's somewhat annoying.
