We go through a box with our cable co. Comcast and they said its not them. Everything is checked off right and turned on. So what could have happened? Can you tell us whatt it is and how to fix it?

My LG Flatron M2262D, about six months old, stopped working with the on screen message 'check signal cable'. I checked it by using it on another set, and it is perfect. Any ideas?

My HP LC4276N TV is 27 months old. A few days ago, the sound just ceased working. Of course, I checked the settings to ensure that "mute" was not activated and that the setting for speakers was "on". I then also tried connecting auxiliary speakers, but to no avail. Could this have been caused by a blown fuse? A bad capacitor? Or is there another likely cause? I would love any detail on how to check any of these potential problems, or any suggestions for repair. (I have no experience in t

I just switched over from cable to an HD antenna. Everything was working fine for about an hour, but now my SHARP LC-42D62U is stuck on channel 21.2 and none of the buttons on the TV work (including the power button).
