I'm new here and I'm not sure about the protocol but I've been unable to find what I need by searching.

I have the basic comcast remote (image)

The cable guy set it up and there's no manual. So it doesn't control my TV and I don't know how to program it. If I could program it for my Sharp TV/VCR Combo I would be eternally grateful. I really only need power and volume. Although it would be nice to get the menu functions I would consider that a non-essential.
