Re: bn44-00604F No Secondary Power
You don't understand, When the mosfet shorted the source resistor went OPEN. Now ALL the 300 volts will appear at the mosfet source. R101 is connected between the mosfet SOURCE and the ic OCP pin. If you think that ic's ocp input handled that, then there is no convincing you otherwise.

Then saw the power resistor right next to the MOSFET was bad and did not show any value. Bypassed it as well considering it was providing GND to the source of MOSFET
