What happens when you point the motorola cable box remote directly at the cable box and CHANNEL UP? Does that work? If so you know your cable box is good.

I would move the wires in the cabinet containing the cable box and it would work again. When the system was professionally installed, it worked perfectly.Ībout 3 months ago, I noticed that I was not able to get a signal all the time. The IR receiver is on my LCD TV in another room and the IR emitter is located on the cable box where i should be able to recieve a signal. The problem I'm having is that my repeater does not seem to be able to change the channels on my cable box.
