I have a 53" Panasonic HDTV widescreen. Has anyone experienced a "popping" comming from their TV? I've had the TV for about a month, and it has happend only twice. It's a scary...kinda loud. I'll be watching a movie, and then it's kinda like a "pop" and then it's fine, so it's not really doing anything to the TV, or at least I think. I'm wondering if it's some kind of anjustment. The DVD player is a Toshiba Progressive scan and hooked up with component video cables. Anyone else ever heard of this? The Tv is fine and is woking w/no probs, but that pop scared the carp out of me.
