Best Fix water-damaged iPhone 6 won’t turn on issue

A water-damaged iPhone 6 won't turn on, how to fix it? As we know, if the iPhone fell into water, even you dry it quickly, but the iPhone motherboard is still very likely to be damaged, such as short circuit. Now, here is the best fix.

Put iPhone on the WL Aluminum Alloy Pad, and use phone opening tools to disassemble iPhone, take off the iPhone motherboard, no obvious scar.

Measure the iPhone motherboard with DC power supply, when supply power to measure the iPhone motherboard,the current is normal.

Press the iPhone power button, the current stuck on 200mA. Obviously, a load on the iPhone power IC is short-circuited.

Use multimeter to measure the resistance of each output grounded on the iPhone power IC, when the PP1V8_SDRAM circuit is measured, we found the problem, the PP1V8_SDRAM circuit is shorted, because the data for C1243 is too small.

Put iPhone motherboard under the Phone Repair 7-45X Trinocular Stereo Microscope, and then apply some rosin on motherboard, and then use Quick 861DW hot air rework station to smoke it, till the motherboard turns white. Increase the voltage in the C1243, after a while, we found a capacitor is shorted.

Use QUICK 861DW hot air rework station and Precision Titanium Alloy Tweezers to remove this capacitor , and then measure it again, now the data is normal.

Assemble the iPhone to test; now the iPhone 6 can be turned on smoothly.

The repairs end!
