Does anyone have the manual for repairing a Delta DPS-180AB?

Hi, have you measured the voltage on the +5VSB line yet? Is there no signal there either? Delta makes high-quality circuit boards, so the problem may lie in small details, such as a blown diode or failed optocoupler in the feedback loop. I usually get the documentation from manualmachine.com . I work at a service center that repairs office equipment, and we regularly deal with these power supplies because they’re often found in HP or Dell systems. Just last week, I looked there for the pinout of the connectors for a similar module because the contact pitch is sometimes non-standard.
