Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
Set up of tv stopped while Roku was adding channels after an update on 58” Onn Tv. Screen with different shades of white/gray vertical lines are now the only thing projected on screen. Tried a reset after a period of time. Tv was out of box and functioning for 10 minutes and can’t get to home screen. Thank you.
Have you tried contacting Onn support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
