Hi, @kristin11.
Greetings from the Roku Community, @kristin11!
Thanks for reaching out. We'd be happy to help you contact the right support.
This seems to be a hardware issue, and it would be highly recommended to directly coordinate this with your TV manufacturer, which is ONN Support, as Roku only supports your TV's running software operating system.
You may reach them here: ONN Support
We hope this will be sorted out soon.
Best regards,
Carly
