I just bought a used (thats my problem) Yamaha CDC-585 CD player and it worked good the first couple times I used it, but now the disc tray won't go in all the way. It gets stuck out about a half inch and just sits there until you open it again. Anyone have any idea what would cause this or if this is a known problem on these players or anything? I am going to take the cover off today and see if maybe I can see something. Thanks....
