Ok. Had this problem come up yesterday. Chat with online CSR told me to power cycle the remote box. That didn't do the trick. Did not get any instruction regarding entering 987 (or whatever that code was). Power cycling didn't work. Was told to exchange the box which I did. Same problem. Thinking back to my troubleshooting days, I now believed the problem is NOT with the remote box, but, rather, with the main box. I power cycled the main box then the remote box. Miracles or miracles... The remote box was now responding to the remote. So - If this happens to you, give a power cycle to the Main box!
