Only major liquid damage was on the max77812 area. I’ve replaced the max77812 with new on but I only shows 1st NINTENDO logo then go black/shut-off. If press power button(if charger plugged-in it will do auto restart 1st logo loop) it will do the same thing. PI3usb and M92T36 replaced but make not difference.
Possibly destroyed one on the list:
MAX77620AEWJ+T
MAX77621AEWI
STM32F38C6T6
Try to reflow Tegra SoC and eMMC
