PS1 Spindle motor not spinning

I have a SCPH-1001 model PS1 with a PU-8 board (later model). I have not been able to find a schematic for this version. The problem is the spindle motor is not spinning. The laser moves back and forth on the rails fine and attempts to focus when power is applied but the spindle does not move. I have used a 9V battery and the spindle motor spins up fine that way. I believe it is the IC722 chip but I’m not entirely sure. anyone have a schematic or suggestion for this board?

Answer this question I have this problem too

Is this a good question?

Hi!

First of all, I would get a new laser deck and replace

It.

Guide: PlayStation Optical Drive Replacement

Can you try that first and see how it goes?

Thanks!
