Unit: Samsung J600g
Problem: Received the unit dead, owner says the phone sometimes charge but most of the time it does not.

Initial Inspection: Corroded charging pin.

1st attempt:
- Replaced charging pin but still the same problem

2nd attempt:
- Replace S2MU005X03 charging i.c still the same.

3rd attemp:
- Line trace and Voltage testing finally done.



Upon checking capacitor C5110 positive line should have 5 volts reading when charger is connected..



This unit i'm repairing does not have 5 volts. The perfect solution for this is to replace KTS1681 surge protection i.c but since I do not have it, I just bypassed the 5v line to VBUS_5V_CON




After jumping the line, the unit is able to charge properly..





Hope it helps...
