I connected my new roku premier and get nothing but black screens. I have tried all HDMI inputs and 2 different power cords. I reset my TV to its default settings. Still nothing
Thanks for the post.
How are you powering the device? Is it plugged into the TV USB port or plugged into a wall outlet? Have you tried switching out the HDMI cable to see if that resolves the issue?
If you are still unable to resolve the issue, please send me a PM with your Roku account email address, and include the serial number on the Roku device. I'll be able to assist you further from there.
it's being powered from a power strip
