Handle iPhone 6S Touch Panel Fault Effectively

In some case, we try our best to avoid repairing again. But we can't refuse what we received,  customer is God. But as a professional repair man, no matter what met, we also need to check it carefully, to avoid this phenomenon happens again.

We got a iPhone 6S, question Phone, from one of our client. They DIY it by himself, but it seems the process didn't get a good result. Okay, let us start it.

Following the detail fix process:

Disassemble the iPhone by phone opening tools, remove the iPhone motherboard, and then measure the diode data for iPhone touch screen with Fluke 15B+ Digital Multimeter, we found the iPhone touch screen synchronized pin is short circuit. A capacitive filter on the side of the socket, a capacitor directly connect to CPU, we can check iPhone schematic diagram on WUXINJI Dongle.

Now, we need to remove the capacitor with Precision Titanium Alloy Tweezers, after movement, measure it again, it still is short circuit. Now, we need to remove inductance,

Use QUICK 861DW hot air rework station to remove the inductance, and then measure it again with multimeter, short circuit phenomenon still exists.

The socket is short circuit, the capacitor is short circuit, and the inductance also is short circuit, we can't fix it by borrowing power from other place.

So there just existing one way to fix it, dangling touch, we test it and found it can work normally, it is amazing, thanks for our ever experience.
