Hi @KarleyFire
Welcome to the Roku Community!
Have you tried contacting the TV manufacturer - TCL to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS. In addition, Roku TV remotes are solely manufactured by TCL. They'll be the best ones to help regarding your issue.
You can contact them here: TCL Support or call them at 1-877-300-8837.
Please keep us posted on what you find out.
Warm Regards,
Lianna
