I opened my onn Roku tv four days ago but now my screen won’t turn on. It makes the noises but the screen is just lit up a faint blue. I’ve tried resetting it and unplugging it, but nothing happens. How do I get the screen to start working again.
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.
