Microsoft Surface Pro 5 1796 Short in Super IO/SAM M22J9VDC
Hi, I am repairing a Microsoft Surface Pro 5. I did some troubleshooting and found that resistor PR5575 feels hot. This resistor bridges +3P3VAS_REG to +3P3VAS.
I then searched for the component that draws all the current from +3P3VAS and found the problem lies with the SAM/Super IO component U3600 (M22J9VDC/Kinetis K22F MK22FN512VDC12). By removing PR3605, I can confirm that this component is drawing all the current through pin L10 (Vdd).
Can this component (M22J9VDC/MK22FN512VDC12) be replaced? I googled all day and found almost no discussion about replacing this MCU (read/write/program/flash, etc.). There is a store in my city that sells this component, but it is an empty/unprogrammed MCU.
Here I also include the schematic and boardview. I really appreciate your help
