How to Fix the "open tray" problem on your XBox 360
This video is for XBox owners who are experience the "open tray" problem. This is when you insert the disc, a few seconds later, it'll ask you to open tray again, and then it won't even acknowledge that there's a disc in the tray. Assuming you know how to open up your XBox, you'll be able to see the parts of the disc drive. It consists of two parts, the part where the disc spins on, and the laser, which reads the disc and it sits just a little bit away from the middle of the drive. The problem occurs when the laser shifts out of position and sits near the outer edge of the disc drive. To fix it, simply just move the laser back to its original position and it will work again. Avoid touching the top of the laser because that is where it comes in contact with the disc and reads the data.
