sorry 360
it powers on flashes 4 green lights and then goes to a solid green light, but nothing on the screen
Does an xbox require a controller to be inserted in order for it to boot up.. I have just aquired an xbox 360 and it boots up onto a solid green, but nothing is on screen. I haven't got any controllers at the moment.
no, it needs to be on before you can link any controllers to it
Have you tried resetting the display settings?
