My CDR machine has developed a fault. When selecting the analogue input, it seems a DC voltage appears on the the input, but coming from the unit, not being put there. Recording level on the right channel is lower then left and there is an audible buzz on the recording.
Hopefully someone out there has a manual for this machine they could share….

I am looking for a computer cd rom/cd drive part with the same mechanism/loader inside than that one from the CDR753.
Concerning the burner I have find out this in the meantime.
In the attachment from the exploded view this is position 81 -
order code "4822 691 10737" CDR Loader CDL3610/01
The needed computer CD-ROM burner to get various parts is the CDD3610 - go for pictures to the URL
Philips CDD3610 / CDD 3610
Also for the CD Loader - position 131 from the same exploded view
order code "4822 691 10742" CD Loader Unit L1265/51
there must be at least one model of a computer CD drive model (not able to burn). Who know this model number?
I need this modell naming, because I need some parts individually from this L1265/51 loader like rubber suspensions for mechanism, clamper carrier, spring, tray and various gearwheel parts. Such computer cd drives is much more better to find than the CDR765 as used part.
Thank you for advices.

Missprint in the Service Manual from CDR765 - Vpp value of Eye-Pattern Signal ??
Service Manual from Philips CDR765 is here:
PHILIPS CDR765-00-11S-13S-17 SM Service Manual free download, schematics, eeprom, repair info for electronics
On page 13.3 there are two test points for the HF/RF (Eye-Pattern) signal.
1) At testpoint 1 (flex-connector 1001-4/C2103) there are to observe 0V6pp. In the service manual no value for Vpp is mentioned.
2) At testpoint 2 (pin 15, HFIN-SAA7372GP and R3117, 1K) there are to observe 2Vpp at two devices from me of this model. According this service manual the value must be 800mVpp.
Laser unit is the CDM12.4 and the laser diode is a hologram laser (LDGU) from Sharp, model LT0H30PA.
Who knows the values from real live?
And how I can calculate the correct value?
The correct value is of interest in case of an exactly adjust for the output power at the optical pickup - for pics go to

BTW - according SM Marantz CD7 the value for RF/HF signal is between 1Vss and 1V5ss
