Hmm, I got into trying to fix my pile-o-components with problems this week.
So far it's been a sweet run: CDP-991 now keeps its tray closed thanks to a new belt and is as good as ever, DVP-S7700 now reads 99% of DVDs again, LD-S9, after 5 years dormant, appears to have fixed itself and doesn't freak out on CLV discs! Anyway, next on my list is my MDP-650. It's not the best for picture but it does have karaoke function which I'm lacking.
Basic problem is the tray won't come out anymore and the gear is messed up. There is a metal plate that has come loose and I can't figure out how its supposed to oriented or how tight its supposed to be (tried multiple ways and tried turning on and ejecting but it just grinds and nothing happens:
I've been looking for a service manual but can't find one (US model MDP-650) There's an Aus model called MDP-650-D that is a totally different player and the manual for that is everywhere. Would anyone here possibly have a link to a service manual? Any advice on positioning the metal plate would be helpful too, thanks.
