This video shows you how to fix the annoying "Open Tray" error that you will occasionally get when you turn on your XBox 360 console. You turn your system on and even though the tray is shut and has a disc in it, it says you left it open. This is easily fixed though. Start by turning on your XBox 360 console, and wait for it to load. Then start to gently knock on the top of your system, if you have it laying down, and eventually it should start to load your disc. If this doesn't work, either open the tray and shut it again, or try restarting your system.
