Hi Richard
I have obtained the repair manual from a company here in the UK and
have recently tried to re-align the trays.
Firstly the manual although helpful in listing the various parts etc.it
loses a lot in the translation from Japanese to English. I think you
are absolutely correct in your assumption that the trays are arranged.
It is probably necessary to fully dismantle the CD assembly from the
rest of the unit first before any realistic repairs can be carried out.
I have a copy of those instructions if you require one. My problem
was that the initial snarl up was because of one of the two spring
mechanisms that elevate the disc in the drive position had itself
miss-aligned due to a small part of the plastic breaking. This I
repaired and after quite some time I managed to understand the
'Carousel' action of the mechanism. By rotating the small bevel gear
(the white one that drops loose when the unit is disasembled) 5
complete turns the first tray (Tray 2) is made to traverse from the
rear to the front of the unit. Place tray 1 into the rear of the unit
and turn the gear a further 5 turns and it should travel from the rear
to the front as did the first tray, at the same time the first tray is
elevated up to the top front position. the tray will need a little
assistance during this operation since it normally works the other way
up and relies on gravity to lift (drop) the tray into position. a
similar operation is followed by tray 3 so allowing tray 2 to take over
the drive position. I also found that the gears didn't rotate fully five
times the second time but jammed causing the whole mechanism to foul up.
I managed to cure this by disassembling the whole gear mechanism and
turning the 'black gears' to a slightly different position from where I
was then able to rotate the whole mechanism freely. Although it
appeared to work when operated by hand, once I had reassembled the
whole unit it refused to operate fully under power. Thats where I
stand at the moment. No longer jamming but not yet fully aligned. I
will crack the problem yet.!!!
Let me know how you do. I will copy the written procedure if you
require it.

Hi Norman
I have the Denon UD M50. Not having the cd changer problem, but am
having a laser problem - it skips for no apparent reason. Have tried
various CDs, cleaned them all thoroughly, but it still happens. Just
wondered if the repair manual would help. Do you have a link where I
could get a copy of the repair manual? Thanks!!
