[VirtualLife]

I have water damaged iPhone 5 that has short to ground in PP_VCC_MAIN line.

Here a photos where water damage was and i cleaned it with ultrasonic cleaner and removed some of them that was really bad but nothing helped.

The red squares are the were water damage was.

Where should i check?

Inject voltage, must be shorted cap that heats up then.

Thanks! How much amp should i inject? The voltage is about 6 volts in the VCC main line.

How much is PP_VCC_MAIN voltage??

4V 2Amp is enough..... if you cant detect heat with this, you can go up in amps no in voltage and go slowly up....

Thanks! U7 was shorted to ground also from another line so its useless but still its good practice.
