We're runing out of possibilities. I think at this point our only hope is that the remote has one of the RCA Combo protocol setup codes. Please check if you get 2 blinks for any of the following setup codes. If you do, then we can try entering individual buttonm codes, looking for the correct device number.

If none of these are in the remote, then I think you're out of luck with this particular remote.
