UI2L motherboard - Help to find short circuit

Hello,
I have this motherboard UI2L, DAUILMB60C0 REV: C.
On the forum I found only this schematic, https://vinafix.com/threads/quanta-ui2h-schematic.27034/, that refers to the UI2H version, can I refer to that schematic for mine or are they different?

I bought this card as used but it arrived not working.
After mounting it and connecting the power supply, the power supply was short-circuited. Check the DC port and it was short.
I checked the AON7403 mosfet (page 46 of the diagram) and it was short. I replaced it but the board didn't work anyway.
I tried to look for other possible damaged components and found two capacitors near the mosfet. I removed them, but there is still something in short.
Can someone help me locate the short?

Attached the part in question.
Thank you
