Just plug it in, a working PSU should just start up and provide 12V relative to GND.
Signals are irrelevant to PSU startup.

Would you be so kind to share the schematic? I also have a faulty supply i would like to fix.

I have just received a switch with the same power supply, of course it also has issues. Did you have any luck? Also, would you be so kind as to share the schematic as well. Thank you.
