I can get sat and dvd o.k. just not cable.
I checked the signal by unplugging from this t.v. and connecting to another t.v. and it worked great. Could the imput area stop working there is no other way to plug in cable with out going through other devices...............
Ok you hook up dvd to what input... you hooked up sat on what =input.. do you have old vcr around.. try hooking cable to vcr and in a sense use its tuner to tune with . this will tell you if your tv has a bad tuner... just hook the vcr to the same input the sat or dvd player is on
