Prviously programmed + functional remote has stopped working, save for turning TV on/off to a singular channel and volume. Batteries changed. That's not the problem. The Remote is the Serial #1056B03 variety.
The "cable" button does not work to bring up the Guide, or in anyway to change channels.
I have a High Definition Digital PVR Box.
The Box itself and it's little remote "eye" is in clear view o the Controller.
Please help. It's been this way for weeks.
