bornach, The DC rails on this failed switching power supply from a wall wort AC adapter, were shorted together. It could be one of 4 components: 2 electrolytic capacitors, a surfacemount ceramic capacitor, or a surfacemount Schottky diode. Started desoldering each one and testing for the short. It cleared when the Schottky diode (SK26) was removed
I don't think I have a high current replacement diode in this form factor.
