Ok, thanks, Predator864. I have just ordered the service manual for the CD780/00R, but I am still missing a service manual for the CDM-4/19 drive. Anyone here willing to share it with me? Thanks in advance.

The CD Player Service Manual also contains the CDM4 diagnostics.

Meanwhile I believe it would be best to start measuring at the flexband where it connects to the main PCB of the player. The reason for my assumption is that the V_DD of the TCA0372 drops from 5.6V to 4.5V whenever I connect the flexband of the CDM-4/19 to the main PCB. No good sign I believe.

Well, does anyone here own a service manual for the CDM-4/19 which he/she can share with me, please? I think it only makes sense continue measuring when I have understood how the speed control mechanism of the CDM-4/19 actually works. I mean, since the spindle motor is only connected with 2 wires, I assume the laser recognizes the RPM of the turntable and sends back that "tachometer" signal to the main PCB. And, to further understand that mechanism, a service manual for the CDM-4/19 would suit best now. Can anyone share, please? The service manual for the whole player (CD780/00R from Philips) is already ordered by me, but no service manual for the CDM-4/19 was available. And I assume Philips will not fully cover the CDM-4/19 in the service manual of the CD780/00R.

Thanks m8s for your help,
P.
