Arrived with minor liquid damage on U7501 and Q7630 was severely burned. Replaced U7501 and Q7630 then discovered U7600 was getting very hot and replaced that as well.

When turned on power board is power cycling. PPBUS_G3H and PPBUS_S5_HS_COMPUTING_INSIS is steady 8.60V

Vcore pulses to 1.6V every few seconds.

What should be checked next?
