pioneer deh-p9400 cd eject problem

[ppia600]

A friend got a free deh-p9400 from a customer for removing all of his other stereo equipment. He tells me it won't eject cds sometimes so I checked it out. I notice it also cuts off and on when ejecting (cable flexing) so I think maybe its the cable and order it from pacparts and replace it. Imagine that... now it doesn't cut on and off but it plays hide and seek with the cd, lol. You hit eject and the cd will come out (at random distance) and trick you into trying to grab it. I'm thinking it may be one of the several limit switches, does anyone have experience with this happening? I don't want to replace every single tiny switch if its not necessary. Thanks for any help
