How to repair iPhone 6S can not be charged
If the phone can't be charged, it feels bad. Have you experienced this situation? We received an iPhone 6S and it can't be charged.
We found that the iPhone 6S motherboard had a slight water phenomenon, which caused the iPhone 6S to fail to boot. After the repair, the iPhone 6S can be opened normally. However, the iPhone 6S does not charge, the charger does not respond when inserted, there is no sign of charging, the iPhone can be connected to the computer. What should we do to repair it?
Frist ,we use Stereo Zoom Microscope to observe the iPhone charge circuit, there are no visible signs of water damage on iPhone tail plugs.
Considering that the upper part of the iPhone motherboard has water damage，and the iPhone can be connected to the computer, according to the previously repair experience, we should focus on the water damage circuit of the iPhone motherboard. Check it carefully, we find the resistor R4510 is corroded by water.
After check iPhone 6S schematic diagram on WUXINJI Dongle, we know that this circuit for iPhone main power that output to the USB control signal TRistat_USB.
Now, we found the faulty part, so, clean the corroded area and replace the resistor by using QUICK 861DW hot air rework station and Titanium Alloy Tweezers.
Install the iPhone and test it, all functions works normally.
