The t.v. in my mother's room is hooked up to cable. It was working fine last night. Today when she turned it on, the channels will change but they show the same distorted picture. i.e. Whether she puts it on channel 3 or 20 or 30, it shows a fuzzy picture of the same station. I checked the cable wires and the cable input itself and they both are working fine. Are we being told that it's time to put our hand into our pocketbook and go shopping? I'm hoping not. Any suggestions? TIA
