Hi @Alisha89,
Welcome to the Roku 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.
You can reach them here: Onn Support or call 1-844-334-2355.
Please let us know if there is anything else we can assist you with.
Regards,
Nimfa
