additional to the normal manuals he can deliver also the Philips service bulletins, where standing informations about various upgrades include the reasons therefore so as very "hard to find" parts.
From there I have order most of vintage Philips mechanism serv. manuals.

after ordering the service manual check out the flow chart diagram for trouble shooting. You will find there all basic instructions ((e. g. goes lens 3x up and down ?? - yes (continue) or no (check out follow: ............) next step: laser light presently ?? yes (continue) or no (check out APC.....................) and so on)).
I don't recommend to carry out a troubleshooting without service manual except you have the complete necessary informations in your head.

An "Off topic" question: Why I read my first part of post #5 in post #6 ?? I have edit post #5 for adding informations but post #6 I haven't create.

The manuals will not help you locate a "Work Hardened" ribbon cable.

As far as the unit is concerned everything may be OK. It's just that the laser may be on a stiff "lead" and cannot accurately follow the positioning of the servo electronics.

This is just one of the components that a good enginner will keep in stock because it's impossible to test.

Does the lens perform a "focus search" operation at switch on by moving up/down a few times.
Is the laser diode drawing current ?

Yes, the focus search can up/down about 1 sec when switch on.

I have download the service manual yesterday,
then I follow the guiding of service manual to check the power supply voltage.

I found the -7V rise to -5.4V on IC NE532N.

I will check the reason why -7V rise to -5.4V tomorrow.

If you do have access to the service manual and a scope you might just see excessive drive voltages being produced by the servo electronics.

Who have philips cd200 service maunal in English?
Thank you very much!

according the site
http://www.marantzphilips.nl/philips_service_manuals/
there are only two languages available: German and Dutch (similar to German) and not english.
But Marantz CD73 (Marantz version of CD303) is in english but not so explicit than German instructions by CD303 SM.
You can the German text translate scan in in your computer, transform in "DOC"-file about Abbyy FineReader and upload here. Then any member can translate it for you (maybe even in your language from a member, who speak German and your language at the same time)

BTW - what tell you Mr. Heinrich Deppermann (go to post #6) ??
