Cant find any liquid on board.

PPBUS_AON (pin 2/F5200) got 0V (.473 in diode mode)
PP3V8_AON 0V and .340 in diode mode

FF200/1 both got 5V on both sides.
PP3V3_UPC0/1_LDO correct diode mode and voltage when charger connected
PP1V5_UPC0/1_LDO_CORE correct diode mode and voltage when charger connected
PPVBUS_USBC0/1 got 5V

Wont go into DFU mode.

Replaced just in case both CD3217 and still the same issue.

Any idea?

C5250 had 0V.
Checked input voltage on U5200 and there was 5V so replaced U5200 and all working fine now.
Thanks for help.

Keep the fuse out.
Then post U5200 basic voltages: P_IN, AUX_DET, SMC_RST_IN, VDDA/P, IRQ*, EN_MVR, AUX_OK, A/BMON.
