I was playing around with a 16V output AC adaptor and I unfortunately shorted the output VCC and GND by mistake. A spark occured at the end of the wires. Since then, the output voltage is around 0.3 V. I was wondering if there is a common component failure that would explain this regulator failure (which part of a regulator is most likely to fail when the outputs are shorted?). I opened up the device, but there are no signs of component damage anywhere.
Edit: I should have mentioned it is a wall AC-DC adapter and regulator (for a camera I believe, looks like any laptop regulator though) so inputs 120V AC and outputs 16V DC
Hopefully photos can help determine the functionality of the circuit. I really haven't a lot of experience with AC PSUs yet... Hopefully I can learn a bit from this.
So the spark was seen at the end of the wire, but it seems it as destroyed an onboard component... I find this strange.
