Pairing is for roku streamers and roku remotes. An aftermarket remote like xfinity might have a IR code that controls roku tv, it won't be a roku code, it'll be a tv code. What brand of Roku tv do you have?
I have a TCL ROKU TV. How do I pair my Xfinity remote?
Try tv codes under such brands as Admiral, Dynex, Insignia, and Sansui. For directions on actually entering the codes see you cable box manual. Or do google search for pdf of your remote model.
The codes affiliated with the ADMIRAL brand worked. I was able to pair volume and power buttons on the XFinity remote with the Roku TCL tv.
Thanks Admiral code worked for my TCL Roku TV.
I have an RCA Roku tv, does anyone know what the Xfinity code is to use the cable remote?
The Rca Roku tv uses the same code as Tcl Roku tv, so try the Admiral codes also.
Other Roku tv brands that will use the Admiral code include Insignia, Onn, Westinghouse, Magnavox, Jvc, Sanyo, Philips.
For sure the Hisense and Sharp Roku tv's do not use the Admiral, they use the Goldstar, LG, or Vizio code set.
the codes (TCL,Admiral, etc) didn't work for me, but this did (for volume, power, and input buttons) !
If it has a Setup button:
