Program Optik Remote for TCL 55S421

[IanD]

My Optik remote no longer control the volume on my Optik cable box.

For some reason, everything else works on the remote, except for changing the volume on the Optik box.

If this cannot be resolved, I wish to link the Slimline Remote 2 to my TCL 55S421 television. This does not seem to be working.

Is there any way I can fix this ?

Did you recently change out your equipment for any reason? Not sure why it'd suddenly stop working. If you're aware of how to sync remotes, our TCL codes for you to try are as follows:
