Welcome to the Roku Community, @Fairytailer210!
We'd be happy to share further information about this and help you contact the right support.
Please be informed that Roku only supports your TV's running software operating system, and this is most likely a hardware issue. We highly recommend coordinating this with your TV manufacturer for further advice.
You may reach them here: ONN Support
Best regards,
