iPhone X Unresponsive Touchscreen Repair
Duration: 45 minutes
Steps: 3 Steps
Step 1
- Hit the power button to wake the phone up. It boots up fine, but the touchscreen isn't playing along and stays unresponsive.
- Power down the phone and carefully open it up. Disconnect the battery and take out the display assembly.
- Next, remove the motherboard. First order of business: check the Touch ID FPC connector J5800. Use diode mode to measure J5800. Pin 22 reads OL, which means the circuit tied to Pin 22 is open and needs attention.
Step 2
- Alright, folks! We've got an inductor, FL5893, on the circuit. Let's kick things off with FL5893.
- First up, carefully grab those tweezers and remove the sponge around J5800. Now, let's do some detective work! Switch to diode mode and measure the voltage between Pin 1 and Pin 2 of FL5893. If you see a reading of 0, great news—FL5893 is in tip-top shape!
- Next, we notice that the circuit runs over to the third space PCB. Time to take apart the motherboard for a closer look at that PCB. Gently place the motherboard on the specialized Heating Platform. Once the temperature hits a cozy 160℃, use those tweezers to lift the upper layer. You've got this!
Step 3
- It looks like we've got a situation here! A bunch of solder joints on the third space PCB have decided to take a permanent vacation, and the motherboard is sporting some serious warping. Given these unfortunate circumstances, it seems like the motherboard is beyond repair. But don't worry, if you need help, you can always schedule a repair.
