I can tell you what is marked on the MOSFET, this: 10N03L I049
By the way, yes I'm 99% sure that ot's mechanical damage, ther is no sign of
the component exploding and it is positioned right where the screwdriver
goes in the heatsink clip. Plus the owner of the board (not me) has a
history of this sort of thing, in fact I've just spotted another component
with similar damage, marked L24 on the pcb, this is a smaller component,
looks very like a SMT resistor.
