The roku tv in my daughters room is half dark and the other half normal picture. I've done factory reset 2wice today but nothing is working. I need help since support isn't available over phone. I have added a pictures as well.
It's possible that this may be a hardware issue. Have you tried contacting your Roku TV manufacturer 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.
