I just got a new Westinghouse 42" LCD (1080p). When it is hooked up with the Comcast DVR box through either DVI or component, on certain HD channels (NBC, ESPN, INHD, INHD2), there is a white vertical line at the very left edge. It does not happen on other HD channels (CBS, ABC, TNT, Discovery, etc).
Has anybody heard of this problem? Is it the DVR box or the display? Any thoughts?
