Chosen Solution

Good evening everyone, I’m currently writing this because I haven’t found anyone that has the same issue as I have. Briefly, I cracked my P9’s display 2 months ago and since nobody fixes Huawei’s products where I live, I decided to fix it myself by buying a new display on the internet. At first, I didn’t recognise that the display I recived wasn’t the right one, the cable was black so it was supposed to be for the Lite version of P9 (great sellers…). As soon as I connected anything I turned it on but I could see pretty much nothing. Then I finally realized it was not compatible with my phone, then I ordered a new brand one once again, this time from another seller though. I was so happy that I could finally fix it and be sure it was going to be compatible (in fact it is compatible): same problem, I can hear every single sound, everything works but the display doesn’t show up. Now, I can see the screen with a lamp on it and the touch works perfectly, so surely the problem is the backlight that doesn’t turn on at all. Is it possible that I broke something on the mobo or the display that wasn’t compatible messed up the display connector? I’m not trying to buy a new display because I’m mad at this and I won’t waste a single penny on it furthermore. Thank you in advance. P.S. The displays are both Huawei original brand.

I’m surprised people are blowing up backlight circuits for Huawei P9 screen replacement. Did you guys forget to unplug the battery first?

Hi, have the same problem, I think the backlight diode is not working but I don’t know when is it placed on the mobo and how to replace. There is many issue on iPhone 6 but nothing on any Huawei

Has anyone already found a solution? I think I screwed up the backlight circuit indeed. I did see the post on the jumper for a p9 lite.. but haven’t found a similar diagram for the p9.

So I had the same issue, I was able to fix it by following something i found on a forum that was mentioned here. See this diagram

any solution?? I have the same problem, my screen broke and I changed it by a new one that worked for an hour, but after that the screen turned off but operating system is still turned on, I have tried 2 screens and nothing, what is the problem??

Also looking for a solution to this. Unplugged battery as always before changing screen. 2 screens no backlight. Anyone know where the backlight diode is?

I have probably the same problem. I have changed two LCDs the backlight I think isn’t working correct because the lightning did not increase at all and some times the screen is flickering. I have changed and the battery but nothing. Any thoughts?

I have the same problem the diagram given before is different than for Huawei P9 EVA-L09

The solution here aren’t for p9, I’m still finding it difficult to rectify this problem.
