Sega CD Model 2 disc drive PCB schematics? (torn pads)

Post by bobrocks95 »

Does anyone know where I can find these? From what I saw the service manual for the CD Model 2 that is pretty commonly shared just included info on the mainboard, and really I need more circuit details than I think it provided. I was recapping my system with a new desoldering station and it did great on the mainboard but tore some traces on the disc drive's board. It's an odd little single-sided PCB that clearly could not handle the minimum heat setting on the station- I can do some bodge wires but it's not super clear where some capacitor leads are supposed to go.

I have the Sony disc drive, and will be adding some pictures to this tomorrow.

What's missing?

Maybe I'm just completely overlooking it? I want a board schematic that shows the full PCB layout so I know what the capacitors are supposed to connect to, specifically for a Sony disc drive PCB.

Here's the power circuitry for a CD model 1, not sure where it's from though

EDIT: All circuit diagrams seem to be for the Funai CD model 2. The board I need a schematic for is the KSK-1310A and I don't think it's out there. I think my only option is if someone probed theirs and let me know what connects to what?
