I picked up a used PS1 today at a thrift, but it does not seem to be working. When turned on the Sony intro screen comes on and then it displays a menu (purple back bround) with Memory Card and CD Player. This menu even comes up when a game is in the system. Some times a Playstation Screen comes up and then sites there forever. If I put in a Music CD it works fine.

I have no experence with PS1's so I was wondering if this is a common failure for PS1s? I would think if it was going to fail the CD player would go out, since that is where the moving parts are.

Thanks
