Help! My iPhone fell into the water!
Did your phone fall into the water? How do you do it? Do you know how to fix it? We received an iPhone 6S. He once dropped the iPhone into the water. It could not be turned on. After observation, we found that the power IC was partially corroded. We have to repair it immediately.
After cleaning the corroded part, it still won't turn on. The leakage is 6 Ma and the starting current is 50 ma by measuring with DC power supply.
Due to the fact that IC is more likely to cause this failure, we are going to remove it to retest, the problem is solved now. Then replace the display IC and install to test function.
All functions are normal, but it can not charge and also can not connect to the computer now, after replacing U2 u2300, fault still exists, then remove the shield cover, measuring its IC side circuit, we found that the end of the capacitor c2300 corrosion blackened.
After checking the drawing on the WUXINJI dongle, it was found that the capacitor could not be removed because it is not a grounding protection capacitor but a coupling capacitor on the TIGRIS-BOOT circuit.
Finally, replace an old iPhone 6s motherboard with a good capacitor and replace it again, the problem is finally solved now.
