sounds like ground loop hum. I'm not totally up on the fixes for this problem, but I believe that the cable coming into your house isn't grounded properly. Could try calling the cable co to check that out, or get a ground loop isolator.

You may have a bad patch cable comming from the Cable box to your reciever. Swap the cord and see if that corrects it. jonny
