I am new to the world of rear screen projection TVs. I've always been a die-hard SONY guy, but they just don't seem to be up to par when I look at a wall of TVs.
I recently purchased a JVC AV48P776. The picture seems to be fine, except when the TV is on for long periods of time. First the very bottom of the screen begins to shake... then, the shaking gradually spreads upward, until its basically unviewable. I can't even read my DirecTV guide, it's jumping so bad.
