new samsung tv - can't program remote

Thanks for your reply. I already tried all those steps multiple times. All buttons on the Xfinity remote work except the volume and on/off button. Funny thing is that the channel button on the Samsung remote doesn't work now and the power button on that remote turns off both the tv and the Xfinity box.

I also tried an XR15 remote - same result.

Thank you for trying all of that already. We can assist you further from here if you can send me a direct message with the full name and complete address for your service.
