Welcome to the Roku Community, @Why7.
Thanks for reaching out. We'd be happy to help you determine the cause and find you the best resolution possible.
Before proceeding, kindly provide us with additional information such as follows:
- When did you start experiencing this issue?
- Did your ONN Roku TV recently receive any software updates prior to this happening that might have triggered the issue?
- Have you tried plugging it on a different power outlet to see if this makes any difference?
We'll be looking forward to your response.
Best regards,
