00165 won't load macOS after liquid damage

Hi!

I've got a 00165 board which got liquid damaged. I've attached screenshots of the main places I found corrosion
Thing is, after cleaning up the corrosion in these areas and putting the board through ultrasonic, it power up just fine but will crash when loading macOS, showing a black screen with the backlight still on for a while before shutting down completely
Unfortunately, in verbose mode it seems to crash right when switching from the wall of text to the Apple logo, so I don't really get any useful info from that.
I've tried flashing a clean BIOS, and even replacing the SMC from another 00165 board, but I get the same exact behaviour.
Funny enough, when booting High Sierra I never get to the login screen, whereas on Catalina it seems to sometimes get to the login screen or desktop and then crash a minute later.

At first I thought this might be an iGPU problem, but I installed Windows, including the Intel HD6000 driver from Windows update, and I can run Heaven for long times without a single crash.
I've also completed multiple runs of memtest86 without any errors.

Kind of running out of ideas on this one after checking it over for a few days, so would love to know if anyone has some advice?

Thank you
 
Tried SMC bypass and get the same thing, will try safe mode
I've been testing with my external macOS SSD but it does the same with a known good internal drive
 
Got the same behaviour when booting in safe mode(shift held down)
Laptop will show apple logo and loading bar but eventually go to a black screen with backlight still on, then later powers off completely.

Any way that I can find some sort of log of what is happening? Again, laptop crashes after verbose boot changes to apple logo which is no help

Thanks

I had similar problem with 3437 and 00165 nproblem; not fixed.
There is something wrong with Intel Management Engine.
May need to change CPU.
