You can test the internal MOSFET for shorts by checking the resistance between S (Source) and D (Drain) pin of the SMPS IC, look at the spec heet of the IC I attached in my post #5.
The resistance between D-pin and the 4 S-pins are all 30 ohm. So this means U1 is good and not the cause of the short circuit?
