Chinese 1390 130 watt troubleshooting manual

Anyone know where I can download a schematic and troubleshooting manual for my Chinese 1390 130 watt laser, using a RDC6442S-B controller?

No, they are generic.

Yes you can find this easily with a google search

All I can find with Google search is the RDC6442G Controller, which appears to have less components, and is wired differently.

I changed out the RDC6442S-B (EC) controller, and now my screen flashes continuosly, and LEDs 15, 12,and 1 flashes. Any ideas?

I’ll give you some websites that you can just download,
