I've got a Sperry Portable (rebadged Corona Data Systems/Cordata PPC-400), and the power supply is clicking and cycling about once per second, regardless of what is plugged into the PS board. Clicking slows down when power is removed.
There's no documentation I can find, and I do not have the skills to troubleshoot an SMPS, even if I did have documentation.
My thinking is to pull that board and replace it with something new.
Does anyone have the pinouts for this board? Or a better idea?
Thanks!
