This spare parts CDX unit is now functional again. I say spare parts because I took all of the best looking parts from my two CDX units to make the first, good CDX player I completed earlier in this thread. The remaining parts were all there for a functional second unit except for the broken gear that Jacques sent me.
However, this second unit does have a couple of issues.
Cosmetically, the little holder for the CD is scratched up.
Mechanically, the eject side hinge of the CDX is not 100%. It is one that came broken and I had to repair. While the door opens and closes via the door motor okay, the door needs manual help on the eject side to actuate the mechanics that say the door is completely closed. I can press a little on the door (left side) and everything works. When I opened the CDX back up to study the problem, it appears related to the door hinge itself. I think it really needs a new hinge. But...the CDX is usable with this repaired hinge and will work fine in my shop where I intend to use it as a CD source.
Another mechanical (electro-mechanical) problem with this CDX is the touch buttons. I originally had problems with this unit. I had to arrange some spacers on the function posts so the touch pads would operate on some of the functions. That takes repeated opening and closing back up of the CDX in order to get everything adjusted. Right now, all of the control buttons work except the Display selection and the Reverse (<<) button. I tried getting that adjusted but haven't had success yet. I'm not going to spend anymore time right now to get those two things working as I have to move on to my next projects and this CDX is already playable in my shop.
Here is an old picture of the adjustment for the CDX touch buttons. I'm going to go listen to some CDs now.
