Wish my LongWei PS-301 was that easy to fix. No short on output and red light off but it wont start up. No voltage/current shown on LED display and green voltage light pulses once every 2 sec and fan tries to start and stops each time. I have 330V DC from mains rectification. Had this prob occasionally from new but now its almost permanent. No sign of physical damaged components.
@@lmorrison17 yeh, it's a temperamental power supply When it does start up correctly, all functions work perfect to max load and voltage. The initial kick start is tge problem. Did you ever get a schematic circuit diagram for it?

@@mikebloodworth9258 I would start testing fets and transistors.

Thanks.
A nice simple fix and it's ready to die another day lol .
Your right, these things are not very robust.🥲
