Hello @be1inda,
We're thrilled to have you here in the Roku Community!
Thank you for reaching out to us about your Onn Roku TV.
It looks like it will require some assistance from our friends at ONN to help diagnose your TV hardware. With this, we would highly recommend that you reach their support at 9 am – 9 pm EST daily (excluding holidays) by contacting them here.
We hope this gets sorted out soon.
Thanks,
Arjiemar
