xbox one has been working absolutely great since launch day until yesterday,switched xbox on and had a black screen but could hear the tv? i tried going home using the controller and voice command and still just a black screen,i have since found if i switch the tv off and back on i can then see the picture or to play a game remove and reinsert the disc and it will play! if i try and go home or switch between tv and gaming etc i just get the black screen again. HELP microsoft or do i need my 360 set back up? What a joke.
