Liquid damage on U9000, J3300_CWR
Tested with board only.
No shorts on big coils.
When charger switch from 5V to 20V so first couple of seconds it takes 0.26A-0.31A and then drop to 0.041A and stays at 0.041A.
PPBUS_G3H - 12.60V
PP3V3_G3H - 3.38V
PP5V_S5 - 5.15V
PP3V3_S5 - 0V - 0.335V in diode mode
PP3V3_G3H_PMU_VDDMAIN - 3.35V
PPBUS_HS_CPU - 12.58V
PPVIN_S0_PRIM1V8 - 12.59V
PPVIN_G3H_P5VG3S - 12.59V
PPVIN_G3H_P3V3G3H - 12.60V
PPVIN_G3H_P3V3G3HRTC - 12.59V
PPBUS_G3H_SSD0 - 12.58V
PP5V_G3S - 5.13V
PP5V_S5_LDO - 5.14V
PP3V3_G3H_RTC - 3.38V
PP3V3_G3H_SSD0 - 3.30V
PP3V3_G3S - 3.37V
It goes into DFU but a few seconds after 'revive' it reboot.
Any idea?
