Disassemble the iPhone 6 Plus by phone opening tools, remove the iPhone motherboard to check it, the U3200 chip had traces of moldy by water.

With the help of QUICK 861DW and Precision Titanium Alloy Tweezers, we remove the chip smoothly and quickly. And then we found out that the U3200 chip 4-pin pp_vcc_main powered pin had corroded.

Measure the diode data of this pin with Fluke 15B+ Digital Multimeter, it is infinitely large. Check the iPhone schematic diagram found that PP_VCC_MAIN is through the FL3202 inductance input to the U3200 chip 4 pin. The FL3202 inductance has been corroded under the VGA Camera 7-45X Trinocular Stereo Microscope observation.
