Arrived with liquid damage on C5008 C5007 C5002 U3710 and Q1920. Replaced everything and board was fully booting into OS. Appeared to be fixed.

After running OS for a bit board suddenly died. Now when trying to turn on the fan spins on and off twice but nothing else happens, not the normal on and off 3 times. Vcore present at 1.7V

Tried known good bios with no change.

Should should be checked next???

Did you try SMC bypass mode?

Check all SPI Bus Series Termination resistors and traces.
Clean/remove J6100.

Just in case, reball SMC and heat CPU to 180-200 degrees.
