My LCD TV is not showing any cable channels while my other TVs are, what is the problem?

Question

I just recently set up the dish network for Greek shows for my other tvs, but not the LCD one, but I'm not getting any cable channels on there. It's a real mystery to me because this LCD TV was bought in Febuary and I think its too early to ruin on me. So what do you guys think?

Also, I have the high definition in back of the LCD T.V and I wonder if that has to do with anything in affecting the tv?

Answer 1

You mention dish network, which is satellite and not cable.

In any case, if the TV is connected directly to a cable via RF, go to the TV menu and do a channel scan.
If you use a set-top box, then the problem is with the set-top box, not the TV.
