I have had my big screen rear projection tv for 4 years or so. Just recently when I the tv on, the picture at the top of the screen is distorted with a "squigly" picture. It's like the picture hasn't lined up properly. After 10 minutes or so it goes to normal. It seems like it needs to "warm up" or something. Thanks for any help.
P.S. Could it have anything to do with cable box or dvd player on top of the tv?
