Thank you for your answer!
I've already tried AON7200 (8mOhms 40A) and got distorted images on screen. I was thinking that maybe the mosfet couldn't handle the current required for the CPU (or I have a bad CPU).
BTW, I guess the real code is "I" I6, since the low side mosfet is an J5, Couldn't find any info about the mosfet anyway (better pictures attached).
I don't have the P0903BEA, but I'll try to find some equivalent.
High side:
Low Side:
