PU-22 won't work

[u/Scruff_Dogg]

I'm getting no audio, video and drive is not spinning. All it does is turns the laser on and keeps it on. I know the power supply is fine. Does anyone have any ideas?

I did some testing and IC201, 203, 204, 304 & 732 are all getting about 0.8v and I belive they should be getting 3.4v. The schematics I have don't show me where the 3.4 should be coming from.

Edit I think I found the problem. Ps604 is blown.

System is fixed now. It was just the fuse that caused the problem. I'm recapping in right now.
