You have to take the top of the Playstation completely off, and take off the guard protecting the disk. Then, you must leave this off and plug in the Playstation and push eject. Now, leaving the disk drive open, turn the power off. You should now see a white circular object. This adjusts the level of the lense of the laser. Turn CLOCKWISE until the laser hits its lowest point. Then put a cd in the drive and plug the system back up. You will need to check and see if it reads your disks. If not turn the power off and adjust the leveler again spinning it only CLOCKWISE. Once you have found the sweetspot, you should put the entire Playstation back together. And there you have it, it will play the disks of any kind. Except of course, computer disks. Brandon
