Hi,
I have this board from an A1706 which is not turning on.
I do get 20V from the charger.
Checking power rails and big coils on the board, I can see that I'm not getting PP5V_S4_T_USBC and PP5V_S4_X_USBC (enable signal is driven low by CD3215s)
Also PPVCCEDRAM_S0_CPU is not present (created from PPVCCIO_S0_CPU which is present, but enable signal coming from CPU CPU_ZVM_L is low).
And obviously, missing VCore: PPVCC_S0_CPU and PPVCCGT_S0_CPU are not present.
No sign of liquid. CPU gets warm but not hot.
