Bad picture on only one tv? Cable problem?
I subscribe to cable and all my tvs have great pictures except for one. I never had a problem with it until recently. Now it has squiggly, snowy diagonal lines across the screen, no matter what channel. I've tried unhooking the cable wires, switching them out with other cable wires, unplugging the power cord on both the DVR and the TV and re-memorizing the channels but nothing works. Could this be a cable company problem? Any ideas or suggestions? I don't know if some of the settings may be incorrect??
