Okay, just bought a PS2 slim clear case for my son on Ebay. Hooked it up, and some of the games will do a jerky spin, and others will spin normally right away. He's in the process of checking all his games, and so far has more that don't work than work. DVDs aren't working either. It doesn't matter what color the back of the disc is. What can we do?
Seems like you have a bad PS2. You may want to return it ASAP. Having to fix or rig your disk is totally unacceptable. This is not your fault nor is it the fault of your disks. If it does not work the way it was designed, return it as it is defective.
I hope it wasn't a used unit from somebody else's problem stock. Good luck.
