I have a TCL Roku 50S423-CA TV and found that Comcast Cable (Xfinity) code 11756 worked for me. This was after trying 3 different XR11 remotes.

None of these solutions worked for me.  But I did eventually get it working.

I've discovered that the remote is a Comcast/Xfinity remote and you can use the instructions for that to program the remote.  The basic instructions here are not exactly correct.

First of all, you just need to press the TV button and then hold the Setup button until it blinks twice red and green. (about 5 to 10 seconds)

Then, you just enter the codes for the TCL set you have.

These are the possible codes I've found for TCL:

11756, 12434, 12290, 12292

• One of those should work for you.  I had to use the second one.
• By the way, if you start entering codes and it starts entering numbers on your tv set, you did something wrong and have to start over.

That gave me partial control. I can do volume, channel control and turn off and on BUT when I turn on the TV input does not work and I cannot use the cursor to navigate the Roku home screen.

The code 12434 worked for me! Have a brand new TCL 4-Series 55" 4K UHD HDR LED Android Smart TV (55S434-CA) -2021

Also, some of the instructions for inputting manual codes are wrong here. Found correct ones from Xfinity's site (bluecurve uses their platform). For the Xr11 remote Just press and hold the setup button for a few seconds until you see the red turn into a solid green light at the top. Then enter the 5 Digit code - the remote will only take 5 digits and then go back normal mode. After that try the volume keep to see if it worked. 

Thanks!
