Servo PCB for L1210/65 (CDM12.1/VAM1202) from Daisy -where in use by Marantz (Schema)

[tiefbassuebertr]

I need a schematic for the Servo/Decoder PCB, which is in use in the loader L1210/65 from Daisylaser (for mechanism CDM12.1, VAM1201 and VAM1202) - go to
pictures
Daisy call this PCB as follow:
"New CD7 II (SAA7327) servo-decoder for improved playability and reliability"

I read follow numberings on the PCB from Daisy (have a look to the PDF images):
1) HECD-019A
2) DN24A533

there are additional informations, mostly unfortunately in french language.

are to find the predecessor of this servo boards at a CD722 from Philips (scroll down).

There was produced several top class cd player in very small amount, where this PCB is in use. AVI (lab Series), RESTEK (Mini Pla), Northstar and various models from Micromega are examples.
Here some links of such brands:

Unfortunately this PCB isn't in use in Philips/Marantz CD Players like CD710, CD722, CD63 or CD67. Thus the service manuals are not helpful.

Who knows brands, which have produced cd player in large amount where this servo board is inside (like Marantz) ??

Such brands must actually publish the schematics (in opposite to DaisyLaser).

Thank you very much for advices

Hello, yes - this is the servo-board used in the AVI lab series CD-Player ... here are 2 better pics - the green side is modified by AVI.

An externally hosted image should be here but it was not working when we last tested it.

HECD-019A

I am tearing my hair out trying to identify transistors T905/904/906 & 907 on this PCB. It is out of a Cyrus CD6 CD player. Also require a schematic. Can anyone help me? There is no DC on the tray motor when given the open/close command.
David.

Thank you for this helpfull information. My friend who owns the Cyrus CD6 player has decided to send it to the service agents in Sydney (Aus). So that's one more problem I don't have to worry about. But your helpfull info was much appreciated.

Hi all, who can help me?
I have a CD player using 1) HECD-019A 2) DN24A533 is spoilt.
Where can I buy it? I contacted Daisy, but no reply.
Your help is appreciated.
Thanks

I'm looking for a circuit of the HECD -019A servo board. Its used by Cyrus in their CD6 and CD8 series CD players.
I have tried Cyrus who wont help.
Daisy , got no reply

Did anyone have any sucess in getting a circuit ?

Unfortunately no success until now.
The actually question is an other:
In which Philips/Marantz models (both CD Players , burners, ghetto blasters and Hifi systems) the same boards are in use?
If I know this, it is easy to get schematics and service manuals.
Maybe Cyrus and AVI know this - try to call and ask this question. My english is too bad for a call by phone.

 

[Ianmac]

Thanks for your reply
You will find Cyrus less than helpful on any technical matters.
I think your advice to search out which Philips /Marantz models used the same board is relevant.
I will try and do this.
If I get anywhere i'll report back

I know it's not helping much, but found this same Servo/Decoder PCB with loader L1210/65 in a Sugden CD21

I see that this servo was use on Shanling CD-T100 . Look at the link: http://lampizator.eu/lampizator/references/SHANLING T100/CD-T100_Schematic Diagram.pdf

Hello everyone.
I am working on this Philips servo mechanics.
I am going to copy the servo board.
can i kindly know what this P87C58 chip is for, it would look like an eprom.
unfortunately there is no wiring diagram on the network.
