On my rear projection TV, when watching a DVD – pausing it while there is a black background – I see faint, very intermittent waves that pretty much run vertical or from top to bottom….there looks to be 8 to 10 of them and they kind of dance, moving left and right. I have narrowed it down to being my TV’s problem or my house (something electrical). I know I need to find out which is causing it, but does it sound like it’s grounding or something in the house causing it? These lines are noticeable on a pitch black picture or very dark scenes in movies. Also, they are visible on my DVD player’s screen saver. I have tried two different outlets on two different walls; two different DVD players, different cables, with and without my surge protector, but they are still present. Now, I did hook up a different TV – I didn’t see the waves, but the blackness looked less stable. Also, it was a different kind of tv (direct view). For some reason though, it sounds like a grounding. If you think so, how do I fix this? My house is new --- built last year.
