Question about Mitsubishi WD73727 73" HDTV
Identify first if the lines are caused by interference, bad cable connection, loose cable ports or bad line. You can do this by attaching another TV to a signal source or trying out a different source such as a DVD player. This is to isolate the problem. If the problem is still present regardless of the source then the issue could be on the board. This might be brought about by soldering that had come loose or a bad IC. For know I would advise to have the TV disconnected overnight to reset it and see if the error is just within the TV's software. Proceed with the other steps once the problem still exists after.
