Help configuring Roku device settings, using Roku OS features such as screen mirroring, adjusting display type and audio settings, using Guest Mode, and assistance with software updates.
I have a Roku Premiere+. It has been working forever. Tonight when I went to turn it on the Roku letters come on and bounce. Then the tv goes black (it does say 720) then a screen pops up that says Incompatible Video Signal. I have unplugged and replugged both the HDMI and the power. Many times. No luck. Can anyone help?
