Xbox One Black Screen

My screen goes to the green loading screen and then turns pixelated and after that I get a black screen and nothing. I let it run for about 20 minutes like that. Nothing happened so I recycled it and now I can't even get a green screen.

 

Check your AV cable

Turn off your console.

Unplug your AV cable from the back of your console, and then plug it back in again.

Turn your console on and check for the display problem.

If the problem still happens, make sure you’re using the correct AV cable and console display settings.

Try to change the screen resolution

Press the Guide button on your controller, go to Settings, and then select System Settings.

Select Console Settings.

Select Display.

Select HDTV Settings.

Select the appropriate screen resolution for your TV or monitor.

Try to improve color quality

Many HDTVs display better color if more color information is provided. The Xbox 360 console can send additional color data to your HDTV to optimize your picture.

Press the Guide button on your controller, go to Settings, and select System Settings.

Select Console Settings.

Select Display.

Select Reference Levels.

Select the option that works best for your TV or monitor.
