samsung galaxy s4 mini gt-9195 no power on
 

hello guys

i have the s4 mini with no power on...

so im messuring the battery connector with my multimeter on diode mode and i have 1320 with + to + and - to -

also i have 385 with + to - and - to +

so i plug in my power supply and i have no power draw at 4 volts...after pressing the power button i have 60 mA draw..nothing else

so far i have test and messure capacitors and didnt find someone damaged.

what you think for my problem?

also i need the electronic schematic for this board

thanks in advance guys

1-check a heating ic and replace it

thank you for the replay

yea i have already look for this....

i feel power ic and emmc ic little hot but im not sure cause the current draw is only 60mA

Put the power supply voltage at 4.3v and check
Or you can as well use freeze spray 75 it will show you faster heating ic and components

My advice for you :
Software:
Flash a boot file
Hardware:
1- clean your motherboard with ultrasonic cleaner with tiner liquid
2- check input and output voltage for power ic (pmic) same as schematic
3-resolder power ic(pmic) using past not flux not a long duration cause past can not stand longer time like the flux and of course you know the difference between this two
4-use z3x jtage to repaire emmc
5-replace emmc

i have the same power draw at 4.3 so the heating procces is slow...

i really need the schematic to anderstand the current path and all that...or the schematis of the power ic atleast

thank you for your time my friend....

i have no schematic for power ic...can help me with this please?

hmm something whorng with the link?

Copy the link and past to yor browser it will open
