You have to remember that the channel numbers shown on the cable box can be completely different than those you tune on a TV directly connected. So the first thing I would do is look around. Channels get moved all the time and the box is "remapped" to still show the same numbers and that's what's shown on the guide channels.

Then analog channels get removed and put on a digital QAM channel along with up to 9 others. The box will still show the old channel number but you may have a problem finding it.

I really doubt that this is a wiring problem, but why not have them look at it.?
