Is anyone else getting red,blue, or green lines when watching some programs on cbs hd? Off and on there will be a single line on the left of the screen which will appear for a few seconds and then disappear. One day its red, the next blue,etc. It does not appear to be on of the shows that are live,ie the superbowl, but I see it everytime I watch csi or any other hd programming on cbs. It does not show up on any other channels. I have a 6200 box and am in new lenox.
