Huawei Mate 20 lite: Replaced LCD and touch is not working

Tue, 04 Mar 2025 01:37:51 -0700

Hi guys, quick question. I have tried to replace an LCD to a broken Mate 20 Lite and after replacement the touch is not working. Thought that is was a detective replacement and had shipped another one , tried the next replacement and realised that it does the same. Initially I thought that there was a slight chance that I might have damaged the LCD on reassembly but the second one I tried it without putting anything back together and it does the same. Am I missing something? The original broken screen was heavily shattered but the touch was working fine. What am I missing?

Huawei Mate 20 lite: Display only working for a fraction of a second

Sun, 15 May 2022 10:21:33 -0700

Hi,

I just replaced the display for my Huawei mate 20 lite, however, upon reboot the screen appears to not work properly. When I turn the phone on, the android logo and text display correctly, and whenever I turn the display on it also works for a fraction of a second. Then the display only shows vertical lines. I have attached a couple of videos to show the problem. Does anyone know if I installed the display wrong or the software prevents swapping displays or maybe the several drops damaged something?

Thanks!

Huawei Mate 20 lite: Ghost touches and ghost burn in to black screen

Wed, 03 Feb 2021 08:23:32 -0700

Hello,

For months I saw very little “ghost burn ins” on my mate 20lite lcd, but I did not bothered me much.

One day it started making ghost touches in many parts of the screen. I have managed to turn on visualisation of touch so it was making line. And ghost burn ins intensified, screen colors became not so solid. After lock/unlock phone for couple of seconds ghost touches fixed.

Then it went to black screen with backlight working. I have restarted couple of times , then lcd was back to showing things with big burn ins. some vertical lines appeared but then disappeared. I have left it to battery to die over night with youtube video. Next morning it was dead black screen with backlight working.

I opened and found one red water indicator near charging port, but it was never wet moderately, maybe few small drops. Left it open in silica gel for a weekend ,after weekend turned it on, and screen was alive for like 30sec with touch working.

Then it went black again. Phone is vibrating when restarting but not making any sounds, and is recognized by computer. Charging led is ok, sometimes after many restarts backlight blinks 3 times. But that is it.

I know it is a long and very abstract read but I have an opportunity to buy motherboard cheaply, and screen is about same on chinese store. I dont want to buy both. Any suggestions?

Huawei Mate 20 lite: Mate 20 lite no backlight / display issue

Mon, 04 May 2020 02:33:32 -0700

I noticed that in very low light situations, mostly at night (so with low screen brightness and very dark environnement), my screen does not seem to display true black. Basically I can tell if the screen is powered on or not when a true black image is being displayed. It's almost like the backlight of a LCD display. I tried to replicate the issue in the day but to no avail. What can I do?
