简介
使用本指南更换损坏的或损坏的华为 P20 LCD 屏幕和数字触控器。
'“注意”':本指南指导你仅更换屏幕,而将原始框架和母板留在原处。但是,此手机的某些替换屏幕已预先安装在新的机架(也称为机架)中,这需要非常不同的过程。
在开始本指南之前,请确保配件正确。打开华为P20会损坏设备上的防溅和防尘密封圈。如果你不更换粘性密封圈,则手机可以正常工作,但会“失去保护”。
由于手机的设计原因,我们建议你卸下锂离子电池,以便卸下屏幕并更方便地使用部件。但是,可以在不取出电池的情况下取出屏幕。'''在强行卸下变形的电池后,可能会造成安全隐患。在这种情况下,请更换新电池。
''在拆卸手机之前,请将电池放电至25%以下”'。如果电池被意外刺穿,可能会着火和/或爆炸,但如果放电,则发生的可能性要低得多。重新组装设备时,你需要使用“新的粘合剂”来重新连接组件。
你所需要的
-
-
在左下角插入第三个空位。
-
从手机的左下角开始滑动三角撬片的尖端,以切掉粘合剂。
-
将三角撬片留在左上角,以防止胶粘剂重新密封。
Davor auch aufpassen da ist das Flexkabel des powerbuttons
Hi Maximilian,
danke für deinen Hinweis. Du hast vollkommen Recht und ich habe den Warnhinweis entsprechend ergänzt.

用镊子将后置摄像头旁边的黑色胶带从主板盖上撕下。
Do I have to conserve that tape?
Hi Belén,
the tape is more of a protective film and doesn’t have a function which would affect the phone when not reapplied.

将显示屏柔性电缆穿过中框的间隙,然后卸下显示屏。
What size replacement adhesive tape do you use when reapplying?
Hi Tim,
for the left and right edge you should use 1 mm, for top and bottom it can be a bit wider. Or can use the Precut Adhesive Card.

如有可能, 把你的手机开机,并且在重新涂抹粘合剂之前 测试你的维修 。
以逆序来重组你的设备。
确保新屏幕的最佳方法是用custom-cut双面胶带纸。将胶带粘贴到屏幕背面,然后小心地将显示屏电缆穿过框架。对准屏幕,然后将其按入到位。

What size tape do you use to reapply?
Hi Astrodoge,
that‘s right. However due to the phone’s design, we recommend removing the lithium-ion battery in order to remove the screen and have better access to the components. We mention this in the introduction of this guide.
Hi guys fingerprint sensor on my Huawei p20 Pro stopped working but I didnt want to attempt screen removal as the chances of damaging the screen were high, but what if I could remove and replace the sensor without removing the screen at £6.00 a pop on ebay for a replacement sensor against a ton plus for a new screen, I opted to take a chance with the sensor, so I removed battery cover glass then all removable parts in the sensor area, once removed I could see a big enough gap to feed the sensor through, now the tricky part I smeared vaseline on the area of the sensor ribbon that fitted between frame and screen and carefully slid it between the frame and screen, now all that was left was to connect the sensor to the connector, there was no way that I could see to slide the ribbon under the frame to connect it so I laid it over that part of frame and connected it to the screen, before I replaced the sensor the phone wouldn't recognise it at all so I was relieved that it detected it now. Works perfectly.
