Would it be too much to ask for a silkscreen view of the PCB (4510-9600-0002)?
Sorry, the schematic is all that I have.
A few years ago, I obtained a service manual for a Tenma 72-8340A switch-mode power supply. The manual turned out to be a Manson document that covered their NPR-2050, 3630 and 6016 power supplies. If you can identify a re-branded version of your power supply, then a service manual might be available from a supplier of an alternative brand.
