Oppo a37f died due to vph_pwr voltage

[DentaGsm]

oppo a37f early came dead

Plug the PC in no second
unloading test using ampere PS shows 0.008ma
suspect the system's working power can not provide voltage to the CPU / EMMC
unloading cans check terms of work
I guarantee check C related to VPH_PWR
because of this the input voltage for the IC power works
traking C related to vph_pwr voltage
vph_pwr should produce 3,8v teg
in the end we found C that leaked a little thank God done
below is a picture of Measrument Point Power Supply oppo a37
I include for educational reference material .
