| Huawei P40 Pro Screen Replacement |
|
|
Introduction |
| Use this guide to remove or replace the screen on your Huawei P40 Pro. | | | If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure. | | | Due to the device’s design, you must remove the lithium-ion battery to access the display cables. If the battery was deformed during removal replace it with a new one—reusing a deformed battery is a potential safety hazard. | | | Before disassembling your device, ***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 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. | | | Before you begin this procedure, be sure to have a set of replacement adhesives for both the back panel and the screen. |

Conclusion |
| If possible, turn on your device and test your repair before installing new adhesive and resealing. | | | Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing. | | | ***To reassemble your device, follow these instructions in reverse order.*** | | | Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%). | | | The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen. | | | Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]]. | | | Repair didn’t go as planned?
