Re: VP2030b Power Supply Problem
Try heating up that startup cap with hair dryer to see if the power supply will start running again, capacitor ESR goes down when heated. If the MOSEFT shorted out, it can also take out the Gate drive circuit inside the IC plus any diode and resistors connected to the Gate of the MOSFET.
