Welcome to the Roku Community, darbywpd!
Thanks for letting us know about this. We'd love to help you contact the right support in cases like this.
Firstly, please be informed that Roku only supports your TVs running software operating systems, and this seems like a hardware issue. Have you tried directly pointing a flashlight at your TV screen to see if you can see anything?
If not, we highly recommend directly coordinating this with your TV manufacturer for further assistance and clarification. You may reach them here:
We hope this will be sorted out soon.
Best regards,
Carly
