After checking, we found the area that was seriously damaged by water, there are 6 pieces capacitors on the left corner are corroded, directly remove it by the brush. Because they don’t affect the boot of the iPhone, so we don't need to deal with them now. Pic 2



Put iPhone under the Trinocular Integrated Microscope, we found these two capacitors also was burned, after testing, they all in short-circuit status. Open the ZXW Dongle to check iPhone schematic diagram, we know that the C4910 leads to the iPhone ringtone amplification U4900, and the C3310 leads to the iPhone charge tube U3300. Check these 2 ICs, there are no trace of water, possibly is these 2 ICs are damaged.  Pic 3



Take these capacitors out and test the iPhone motherboard, the iPhone layer board doesn't short, re-fill these capacitors, and then test it with DC power supply, the boot current tested is normal. After dry out the iPhone display screen, connect it to the iPhone, and then power on iPhone, the iPhone screen can be lit, but it turns darkness gradually.

Replace it with the new iPhone display screen, and test it again, now the iPhone screen works properly, and all functions tested are normal. Pic 4
