I have tried every single RCA tv code and nothing seems to be working to sync the xfinity remote with this model RCA TV. The guide and channel buttons work but the volume and Power button does not. Has anybody figured out a solution with this tv. I was on the phone with customer service for an hour and nothing seemed to work. Starting to think it’s just not possible for this remote to sync with this particular model RCA tv. I wrote RCA and still waiting for a response back. Any solutions would be greatly appreciated. I really would like one remote to control this television. Could a universal remote be a possible solution that’s not xfinity branded?
