1970s Zenith All-in-one Stereo with record player issues

[Captainclock]

Seriously? No one's had this issue before?
Considering how problematic these later BSR Changers were I'd be surprised if anyone on here didn't have any issues with them if they've ever had a stereo with one in it, because I know for a fact that every single stereo I've ever encountered that had one of these old late model BSR Changers in them all had issues with them of some sort whether it was the power switch being stuck in the off position, a mistracking tonearm, or a malfunctioning changer mechanism, and even a malfunctioning tonearm drop mechanism (which is what I'm experiencing right now with this old Zenith).
Anyways it would be really nice if someone would give me some ideas of where to start looking and or troubleshooting as far as fixing this changer's issues goes.
