Welcome to the Roku Community, @Deadeyebubby!
Thanks for letting us know about this. We'd be happy to help you contact the right support.
This could be a hardware issue, and we highly recommend coordinating this with your TV manufacturer for further assistance, as Roku only supports its running software operating system.
You may reach them here: Sharp Support
We hope this will be sorted out soon.
Best regards,
Carly
