How to fix iPhone Screen Isn't Displaying After Screen Replacement

Introduction:

We’ve received feedback from technicians at phone repair shops about occasional screen malfunctions occurring after installing phone screens. (These issues can also emerge a few days after the screen replacement.)

After a meticulous inspection by our InScreenZone QC team, we’ve identified that these problems are primarily caused by damage to the phone screen assembly’s flex cables.

Despite their flexibility, these cables can develop significant creases, leading to cable damage as seen in the image below.

This situation often arises because the phone screen assembly isn’t properly folded and placed in the device’s groove during installation.

In the following sections, we will demonstrate the correct procedure for replacing a phone screen, using the iPhone X as an example.

Step-by-Step Guide:

  1. Before installing the phone screen assembly, consider gently bending and shaping the flex cables.

Tip: Ensure that the bending occurs at least 1mm away from the edges to avoid cable damage due to bracket pressure during rapid installations.

Note: Before snapping in place, verify that the bent portion of the cables aligns perfectly with the motherboard’s groove.
