Board got liquid damage around U7410/20/30 and J8500.
Is there anyway to check if CPU is still fine?

Other damaged area is J5100, U3200, UB300.
5V 0A on charger.

Found short (0.003V in diode mode) on PPBUS_HS_CPU.
Started to remove U7410.. etc one by one and when U7430 was removed short gone.

Found short (0.002V in diode mode) on CPUGT_PHASE1/2/3

Any idea?

CPU got overvoltage through U7430.
Don't waste time with this board.
USB-C is also damaged and many chances T2 too.
