Huawei P9: P9 turns on but screen doesn't light on

Mon, 06 Dec 2021 04:00:39 -0700

So my phone has stopped "working". The last days that i could use the phone there were some errors ( apps closing and bugging). But one morning i waked up and the screen won't turn on.

But when you hit the powerbutton the phone vibrates and makes sound..

So what could be wrong?

The screen? but its strange because there are no breaks in the glass..

Thank you guys

Huawei P20 Pro: Microphone appears muffled and quiet

Wed, 03 Nov 2021 16:56:40 -0700

Hello all.

My P20 Pro has a problem since being repaired. My microphones appear to be muffled, and do not pick up sound well. They seem quiet but also extra sensitive to physical contact with the phone itself. Would this potentially be the result of dust build up? And is there a simple way to hopefully remove any blockages? Cheers.

Huawei P20 Pro: Screen not working correctly after battery replacement

Tue, 19 Oct 2021 14:13:09 -0700

I’ve just changed the battery of my P20 pro and at first everything seemed to be working fine. Now I’ve realized that the touchscreen is not working correctly anymore. It either registers no input or multiple inputs or inputs way from the initial touch.

Any ideas what may have caused this? Isopropyl maybe (it was only 70%)?

My Huawei P9 touch screen isnt working after screen and frame replacement. Everything lights up and the swipe to unlock kinda flashes. With random jabbing at the screen I can get to the unlock screen but little else. Any advice?

Huawei P Smart: Do I need to melt the adhesive before attempting to remove the back?

Fri, 25 Jun 2021 16:07:08 -0700

Various videos online show people just prying the back of the phone off with a spudger. I assumed I would need to use a heat gun or iopener or something similar to melt the adhesive first? Just want to make sure I do this right

Huawei P9 Lite: Problem with new screen

Thu, 04 Feb 2021 09:23:16 -0700

Hello,

I already replaced many LCD screens or batteries etc in phones, but today I experienced something strange:

I replaced the LCD of a Huawei P9 lite and afterwards everything worked fine. All parts have been working (touch, screen, cameras, finger sensor etc) and all software was fine.

Then after a while the touch was not working anymore. I did a restart and since then I got vertical stripes on my screen. I can still see the normal Huawei logo when powering on, but afterwards I immediately get white stripes…

I did not find any clue in the internet about what could have caused this. Can you help me please?

In the video you can see the stripes.

Thank you very much!!!

Huawei Y625: Huwawei Y6 Pro keeps shutting down.

Tue, 14 Apr 2020 22:43:50 -0700

Huwawei Y6 Pro - shows the battery at 1% even though it was charged to 80%, (give or take) with another phone. It keeps initiating a 10sec countdown to shutdown every time.

(just a short background) The owner brought the phone to me with empty battery and unable to charge. After probing, he also mentioned that he had possibly wet it, dropped it a few times, and had smelled faint burning plastic and gets quite warm while it is being charged. He further complained that it could only be charged when the charger is inserted in a certain way or when a specific charger was used.

Now I am beginning to be concerned at this point, thinking the fault might be in the battery’s “over discharge protection circuit” that’s telling the system the battery is too low and it needs to shut down. OR

if the main board as a whole is faulty (now replacing it isnt an option as it costs about same as the new unit).

how do I know it’s the over discharge protection circuit? If it is indeed the case, Can I bypass it either via software or a jumper wire?

What other possible issues have I missed?

Update:

I used another battery and connected it to the mainboard. It did work just fine and was able to game with it.

The issue though is that as soon as the battery is connected the board heats up hitting about 100°F or 50°C on the thermometer even when the device is turned off. The heat becomes uncomfortable within 15-30 mins.

but then again, the phone works and the battery isnt the issue.

Does someone know what could be wrong and if there’s a possible bypass required.

My Honor 8 won't turn on after drop. Only red LED lights while it is plugged in charger. Can you help me ? Phone is on first sight not damaged. Could it be display issue or some pins inside just disconnected? When I connect it to the PC it shows up and disconnect and this repeats.

Huawei P9 Lite: Bootloop because of fingerprint scanner?

Sun, 23 Jun 2019 10:15:53 -0700

So, they gave me a p9 lite to check as it was getting pretty hot and it's fingerprint scanner wasn't working. Opening it revealed a disconnected scanner and no thermal pad. I plugged it in and it started bootlooping. Cache clear, factory reset and flashing the proper rom from a sd card didn't solve the issue, what can i do besides getting a new motherboard?

Huawei Mate 9: Huawei Mate 9 PRO's screen is broken and looking for ways to replace

Wed, 10 Apr 2019 02:54:24 -0700

I am using Huawei Mate 9 PRO and the LCD screen was broken. Went to Huawei Customer Service Centre and realized that it was going to cost me RM841.60 which is relatively pricy. Here to ask for any ways to replace the LCD screen. Would it be cheaper to purchase the LCD screen through online? Which is the reliable website? Is LCD screen enough as I found some of the additional products needed such as touch screen digitizer and frame? Any answers are appreciated.
