Aurora Borealis on my LN52A650A1FXZA

Admittedly a total amateur with HDTV, I have a Comcast HD box ( DCT 6200) plugged directly into the TV, first using component cables and then with a new HDMI/DVI cable, makes no difference. We can't seem to get rid of these mostly horizontal, small, cloud storms that move around the screen among the intermediate tones of the scene. They are very distracting. Not sure what to do, any advice or similar experience?
Thanks

Robert Tiziani,

Welcome to the forum. Happy

Well, there are several ways to figure out if this is caused by the television itself (screen uniformity) or if it's your cable box - or it may be "dirty" electric power.

Does it happen with JUST the cable box? Or does it also happen with the DVD player or any game consoles you use?

It is also possible that it is the compression ratio that Comcast is using on there digital channels. Try hooking up a DVD player and see if they go away.
