I have a Samsung 2003 DPL/HDTV. Model #HLN507W; Serial #31DW600224Z. When turned on the picture is fine but after several minutes the image begins to shake and then freezes, the picture is now distorted. Can someone tell me what the problem is and how to fix it. I don't think that the problem is the cable box.

First unplug the input wire from the cable box and plug it directly in to the back of the TV to see if the problem still exists. You should be able to get about 72 analog channels this way. If the problem still exists, its your TV.
