    Model DX-C320.
    PROB #1 The underside of white gear wheel engages the track on the laser carriage allowing it to travel as it reads media. It's skipping/teeth not engaging, just rubbing on each other and making a racket. Carriage won't move on it's own any more. The noise used to happen a little for years, but no failure til now. Fix? Parts?
    PROB #2 Small black gear wheel at rear spins the carousel. Mysteriously, this quit when the other problem appeared. Related? I'm clueless but do have it torn-down. Case/housing off. Thank for any advice, ya'll!
    See pics attached...hope this works....

    Can you move the slide manually?

    If the slide is stuck, the gears will thrash.

    This is a Sony mechanism. You may be able to find another one on E-bay. Look at the metal plate, it should have KSM-something stamped on it. That's the part number, Google it.
    Examine the gears closely. If the teeth are undamaged they may have popped out of place. The white gear snaps into place and is held by a little piece on the bottom which sometimes breaks.
    The belts probably need to be replaced.

    It's a sony ksm2401aan. I found one on E-Bay but it's missing the white gear. Check the condition of the teeth on the gears. I've never seen one with a bad gear, only with the white gear popped up out of place.

    Thx Cap n Doc. Laser carriage does move on the guide rail w minor effort because it's driving the gears/motor...and then zip!...it skips past 3 or 8 teth and settles back in and travels to the end. Harder to get it started at either end of the carriage rail, but I have no reason to think it as stuck. Light dab o wht lithium, maybe? I simply suspect wear and tear.

    Now (see above). What aboot PROB #2 ...when you get a chance?

    Thanks, gents!

    Also, when you power down the unit, the laser assy returns to its resting/off position, right? Wherever that is. When you turn unit on it gets to skipping gear teeth pretty quick w no start/stop or intermittancy (new word?) in the pattern...that is, once it starts slapping gear teeth it will continue nonstop til unit realises error and stops it.

    Also, also...if white gear is popped loose, should I be able to remove it? And wouldn't it be disengaged ALL the time and not spin when testing by hand?

    Check ... the...teeth...on...the...gears! If the gear is loose it will make intermittent contact. All you have to do is push down on it to check it, it will snap into place. From your picture it looks like it is sitting high.

    Ok, ok, ok! If in proper place - snapped/locked/etc.....then?...look for the replacement laser carriage unit as mentioned above? You get gears with that? Or is it the enitire changer tray assy? Have not looked yet. May be rhetorical once I do. TBD. Thx!

    Well, magically, randomly I go out to eat tonight (off-work) and decide to kill time and do a few errands and hit the local Essex Bargain Hunt 5 minutes away. It's a junk store unless you're a picker :) If you've been, you know. So I see an Onkyo DX-C390 6-disc CD changer in-box with remote, with batteries, with cables, with manuals, manufactured Feb 2018...and literally flawless. Think about it, grab it, and head to checkout and plunk down the $90 (after confirming FULL refund policy!). Lady scans it and says, os there a price tag on your side? Yes, $90. Oh, well one on my side says $30. And it was the correct sticker, too! Doofy updating pricing didn't do both sides and I never saw it! Oh, and since it was Yellow-Tag sale (xtra 20%-off Yellow Tag Sale, ended at close that day)...$24 plus tax...and so far...AWESOME! No glitch, nothing. Waaaay highly reviewed by Amazon and Bestbuy (1500+ 4+ Star reviews on both, and recently too) And that's my risk at a useless post/spam, but had to share out of joy. Still want to fix the predecessor (28 yrs old) and will post updates if they don't close the thread. Thanks, ya'll

    Awesome! I have been nothing but impressed with the Onkyo and Integra gear I have heard and owned.

    Congrats on the deal.

    Props and thx Dude. Might have to chunk the broken relic, though there weren't many variants updates in-between. Have too much other sellable, profit-wise, stuff to waste time on. Dam! I'm just way too nostalgic about having/keeping my own personal time capsule of the Glory Days!...Cue the music!....

    Ditched the original. Looks like they didn't fall all over themselves making a new model every year and much stuff can you stuff into a 6-cd carousel for under $200? Thanks!

    NOW.....my matching 1990 Onkyo dual tape deck turns on...and then shortly after, switches off, think after trying to rewind, etc. (long time). Methinks SMPS. Worth fixing?

    Those Onkyo dual decks were actually pretty decent, although I frown on dual decks in general because the manufacturer can't make a deck with 2 good mechanisms in it for the price of a single deck without serious corner cutting. It's better to get 2 nice single non reversable decks if you want to copy tapes.
    Anyway, check the position of the switches on the deck. AMSS should be off, turn the repeat off. It might be that the motion sensor isn't working, maybe there is a tape counter belt that is slipping.

    Mind you this is vintage 1991 and premium for it's time, I paid good money and Onkyo, Denon, Harmon Kardon was top-notch and harder to find. It was tip-top until it got put aside for a handfull of years and then reconnected 6 yrs ago. So, no prior indications...and not very much use in the many years prior due to CDS. Not a trend. Very curious as to final thoughts.
