We have one remote that won’t work out of the 4 in the house. Yes, we checked batteries and when we try to use a different one on that tv, it changes channels in multiple room. Any suggestions?
press setup button on remote until the remote's LED changes from red to green. press 981. the remote is now reset back to factory fresh programming. press and hold setup while in front of the TV you wish to pair the remote (if you wish to make that remote operate just one TV) and press the Xfinity button, and enter the 3-digit number that appears on that TV screen.
