Title |
| Sony Xperia Z4 LCD & Digitizer Replacement |
|
|
Introduction |
| Use this guide to remove a broken or defective LCD & Digitizer in your Sony Xperia Z4. | | | Due to the phone’s design, you must remove the lithium-ion battery in order to access the display cables. '''Do not re-use the battery once it is removed, as doing so is a potential safety hazard.''' | | | '''Before disassembling your phone, discharge the battery below 25%'''. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged. | | | '''Note''': This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide. | | | You’ll need '''replacement adhesive''' to reattach components when reassembling the device. |

Conclusion |
| The best way to secure the new screen is with a sheet of custom-cut double-sided tape. Apply the tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen and press it into place. | | | '''If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.''' | | | To reassemble your device, follow these instructions in reverse order. | | | Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler]]. | | | Repair didn’t go as planned?
