I've had a weird problem pop up - suddenly on two of my TVs (a Panasonic 53WX42 projection and a Toshiba 27inch direct view set) I've noticed "wavy lines" - not really distorting the image but parallel lines on about a 45% angle. They are most prevalent/visible in areas of solid color particularly reds and greens. It does seem to come and go so I am wondering if I've got a device somewhere that is kicking on and causing the problems but I haven't been able to track anything down yet. It just started recently and our third tv doesn't have any signs of it (well in the few minutes I've checked). Oh and the tvs in question are on opposite sides of the house so they would be on different circuit breakers.... If you have any suggestions please let me know! Thanks!
