2] Reset your Xbox One to Factory Defaults If this doesn’t help, move to the next fix. Your machine will reboot in a while if there is no severe issue and you might not see the green screen again.
To hard reset your Xbox One, press and hold the Power button of your console for about at least seconds. If the green screen is due to some temporary glitch, a hard reset will certainly resolve the problem. This is the first thing you should try before heading to the other fixes.
