Hi classmom2,
I will be happy to help.
You have probably tried this but I will go over it anyway. If it dosn't work we will try something else.
From the video menu on the tv, select the tuning band of CABLE not AIR. Then do a Auto-Channel Search.
From what I gather you have basic cable without a cable box correct?
Let me know what you find and we will go from there.
