My iPhone 6 Display Nothing No Matter How We Operate It

Several days ago, we received an problematic iPhone 6 from a customer. He described the problem is that his iPhone 6 touch screen suddenly had no display during the normal use. Let’s do a troubleshooting for it.

First, we need to check iPhone 6 schematic diagram on WUXINJI Dongle, and find the iPhone 6 display socket circuit diagram.

And then, use Fluke 15B+ Digital Multimeter to measure the diode data of iPhone display touch socket. We find that the 26 Pin circuit is shorted, and the display screen shows positive 5.7V.

According to the iPhone schematic diagram, we know that this circuit is output by using iPhone display touch IC, there are 6 filter capacitors on this circuit line.

Based on previous repair experience, we can judge that the filter capacitors are damaged. Put iPhone motherboard under the Phone Repair 7–45X Trinocular Stereo Microscope, and then remove the filter capacitors one by one, when breaking into the third filter capacitor, the data measured is normal.

Install the iPhone, and then press iPhone power button to turn it on, the Apple logo appears on iPhone display screen smoothly. After get into IOS, the iPhone screen is always displaying normally. The problem is finally cleared.
