Probably a generic DVD mechanics question.
One motor for sledge , optical deck up/down and drawer open/close.
Transported by courier and would not accept DVD when received at the other
end - box must have been jarred. Try pushing the drawer in and it knocks the
spinner motor assembly which is in the up / play position. The repair manual
only says replace the DVD unit in this situation. Removed this sub-unit,
N78E3CBN no info found. Delatched the drawer and removed , turned cogs and Z
track etc until only the drawer motion cog moved with no movement of sledge
or Z-rack and reintroduced the tray and optical unit in eject position. Is
this a standard approach to this symptom for direct coupled ie no drive
bands? Seems to work now - but just temporary or fixed proper for normal
use? No cracked /broken cogs/racks or free-floating pieces found.
The drawer seems very flimsey, I assume it flexed and a guide peg got on the
wrong side of a rail. Common problem? with a recognised correction of
beefing up somehow?

looks as though the optical deck jolted from eject to play position , in
transit. Then first use after , nasty scraping noise of drawer sliding over
the spinner.

are not familiar with the manufacturer's recommended starting positions for
the gears and deck, then the method that you adopted is as good a starting
point as any. As a general rule of thumb, if it closes and opens without
catching or graunching on anything when you've finished, then you have the
timing correct. Incidentally, your 'spinner motor' is more correctly known
as the spindle motor, and the little platter on the top, as the turntable.

This looked more like a button rather than motor and platter, it was so
tiny.
At one time with CD decks there were transit screws like vinyl decks. Did
some change do away with that requirement for CD and presumably DVD decks.
Was it just a change of suspension? originally great floppy springy things
and then somone realised you only needed to stop audio feedback, so in came
little soft grommet like things .
