Does anyone know how to fix that. Or if not anyone that I could call in Denver, CO?

Did the cable fitting on TV get ripped off, or did cable separate from fitting.
Worse case, may be able to solder short piece of coax to break inside, and drill hole in back, and install barrel connector.

It was the whole piece that came off.

Your TV cable will have a connector on the end, called an F-Type connector. Is this part that was *pulled* off from the cable?

Is this part still attached to the TV? If it is you will need to unscrew it from the TV and put it aside.

Now, you will have a TV cable with a bare end. (i.e. no connector).

You can go to a hardware store and ask them for a twist-on type F-connector. Simply twist this connector back onto the bare end of the TV cable. Now connect the cable to the TV.

Just thinking on a whole other tangent, does your TV have RCA cables or whatever their called (the red, white and yellow ones) if so just run the cable through that by putting the coax into a vcr or switch, or if you have digital cable it should have the RCA connectors also.

Thanks, actually I did this when the threads on the back of my TV co-ax connector stripped off, actually the video quality was quite noticeably better.

Thank you very much
