Top 1/4 of my 65" Roku screen just went dim compared to the rest of the TV. What happened and what's the fix?
Roku doesn't make the TVs, so you'd have to contact the manufacturer, but I hate to say that you might want to start shopping for a new TV unless you're capable of fixing it yourself. It's most likely a hardware failure within the TV. To start, unplug the power overnight and see if it's better in the morning.
