Hi @Masemama
Thanks for reaching out here in the Community!
Have you tried contacting the TV manufacturer 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.
Here is the contact information for TCL support:

All the best,
