Measure the resistance of J4700_3# with Fluke 15B+ Digital Multimeter, it is normal. Put iPhone motherboard under the 3.5X-90X Stereo Zoom Microscope to check, we found the iPhone power IC was replaced by other phone repair man.

Based on our repair experience, mostly this failure is caused by damaged iPhone CPU, so replace the iPhone power IC is useless. 

BUTTON_VOL_UP_L lower voltage, it has no external pull resistance, it is pulled directly through the CPU internal. Borrow PP3V0_TRISTARUSB controller 3V string the resistance of 1K, so that the voltage is pulled up to 1.6V. 

Assemble the iPhone to test; now the iPhone volume up button can be used normally.
