I totally bungled the disassembly for a rough 5085 I picked up and the keys have these springs attached at the bottom. I wasn't paying enough attention and can't figure out where they go to and how to put the door/key piece back together. They are different sizes across, it looks like the first 3 attach to the small black tabs on the end of the mechanism part but the other 3 are too long and need to activate the play/pause/stop mech. Any help would be appreciated. I think I broke some plastic on the door but at this point I just want the unit to function. My Rx-5050s are so much easier to work on...
