"Hello,\n\nI'm experiencing an issue where after 15 minutes, the picture starts degrading and flickering on my DLP TV.  I can't post a video of it because this is my first post, but does this sort of symptom clue any of the experts on DLP issues?  If I get some more posts, I suppose I can post the video, but until then, I certainly could use some help.\n\nMy HD Comcast cable box is connected via component cables.  This happens from either of the two component connections in the back. \n\nThanks for any clues!"
