My Arris IPC1100 P2 STB no longer responds to all the commands from my P265V RC. I've reset the STB 2x, cleaned the remote and even bought a new one. Failures are the same on old and new remote: I can't see the full guide, I can't bring up the menu or the DVR, control forward or backward video. My other STB and the Media server all respond properly as they should. I also cannot power off the STB using the button on the box.
Is there anything else I should try or is it time to replace the STB?
