JamieClaye I have the exact same problem with my TCL 50" Roku tv, if you look at the post directly above yours. It's due to something in the 11.5 firmware, and an older firmware voice remote. You only need to do a regular power-down with the remote power button, and wait about 1/2 hour. The RF voice remote will no longer work, until a full power cycle.
I bought this much newer model voice remote, and now it stays paired no matter what. I suggest you also try it. $20 isn't worth spending more time on, and I'm sure it'll work for you also:
Thanks! I missed the similar post and yes, a $20 remote certainly is hard to argue with in terms of time spent troubleshooting this.
I just hate having to replace functional hardware, grrrr.
Maybe they'll fix it. 🙂
Thanks again!
