Rotel's naming for service manuals in general is "Technical Manual"Hi!
I bought a Rotel RCD-865BX.It works perfectly,but no sound at the out analog and digital!
There is inside:
U101-TDA8809T
U103-TDA8808T
U107-MN4264P
U106-SAA7310GP
U102-TCA0372DP2
U108-ZC99685P(DIP40) ???
U109-NJM5534DD
U112-SAA7321GP
U111-SAA7220p/B
I need service manual? I not found description for ZC99685P?
Reads CDs, but no sound.
I also looking for a datasheet of ZC99685P (MCU-IC for servo and control) - especially for the software description "P110" (mask programmable version).
Same MCU is in use in Naim Audio's "CDI" - go to post #3 under
https://www.diyaudio.com/community/...cd-1-cds-only-impaired-skip-operation.207813/
P.S.: troubleshooting on working CD player devices without sound (without signal both on S/P-DIF and analog out) must actually be an easy task - because only the SAA7220P and it's peripheral parts and it's supply voltages are in question.

I am confused regarding the mentioned MCU's in the part list of service manual for CD630 on page 9-3.
There are three different versions according the service manual (go to attachment): 00R, 05R and 17R.
Each version use it's own software for the MCU
on page 9-3 is to read this:
1) Version 00R: IC 6530 - Part No 4822 209 60801 type MC68HC05C9P/SC409009
2) Version 05R: IC 6530 - Part No 4822 209 61428 type MC68HC05C9P/409010
3) Version 17R: nothing mentioned
I guess, there are various misprints:
a) instead of 409010 it should probably be called SC409010 for the MCU (Version 05R)
b) in case of used "MC68HC05C9P" there would have to be two different Pxxx numbers according the software version
c) which MCU's are used for the version 17R (maybe the ZC99702P as to see on the images under
https://www.dutchaudioclassics.nl/Philips_cd630_cdplayer/
and
https://insidehifi.blogspot.com/2013/11/philips-cd-630.html)
For answering this questions the associated service bulletin for the CD630 is necessary.
P.S.: according the images under
http://www.goldfinch-mod.eu/odtwarzacze-cd-2/marantz/marantz-cd-40/
the Marantz CD40 use as MCU the ZC99700P (not mentioned in the associated service manual, available by hifi engine)

When the CD is rotates, I hear the magnifier hitting the disc sometimes.Supply voltage is OK.
First of all I thank you for the large amount of details you have provided us which always makes a certain impression to read and from which we also may learn something.
However, please note that my reply was intended to be a starting point that necessarily needed to be explored further (by someone who, after all, had made a rather generic request) just as you in an appreciated way have elaborated.
I think that the one of the nice things of participating to the forum is also this, namely when two pieces of information (which if both correct enough are always better than just one) come together to provide useful guidance to the member who need informations.
Also, please note that I providently said "pretty sure", not "absolutely sure"...
