Hello today a screen replacement i ordered in aliexpress arrived and i did change it carefully (i did this process 2 times 1 in my phone and another in a cousin mi a1. No problems).
The thing is... after this i turn on the phone and the screen turns on but only until rom starts to load and then it comes black as if it wasn't turn on. The screen turns on also in fastboot mode but instantly shutdown when entering to recovery mode or normal boot as i said. The phone is working properly the rom loads and there is notification sounds and touch is working too.
If anyone can help me please. The only thing i can thing of is that the screen came with some strange malfunction.
EDIT: I flashed stock rom with flash_all and got the screen and everything working fine. I then tried again to flash a custom rom as i had before and screen failed to turn on again. Then i flashed stock kernel just to try if was it the cause and after this screen worked fine again but i lost wifi and probably there is other issues because of the stock kernel on a custom rom. I don't know if it may be because a different display driver or a kernel setting that may cause this malfunction. Hope someone can help me to solve this as i really want to use a custom rom.

Hi,
I have a N4 that was new but the screen cracked on it and eventually the battery died as well (wouldent hold a charge). I got the battery and screen replaced but as soon as this happened I could not boot into any rom. I had twrp installed but everytime I tried to install a rom such as CM it would install but would stay stuck in the boot loader. I then used NRT to try and kick it out of bootloader and I tried several different stock firmwares, 5.01, 4.4.4, and 4.2. The only rom that was able to get past the boot animation was 4.2 it went to the welcome screen to choose a language but I could not select anything via touch screen. In that screen I could lower and raise the volume via the rockers and turn the screen on and off. I had twrp installed and the touchscreen worked fine in twrp. I also tried this: http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060 and it also let me get into the developer firmware but of course it is encrypted so I could do nothing. The phone has not had contact with water etc. Do I have any other options? Can I get some type of diagnostic such as logcat or something?
Thanks!
I messed up with my LG G2 D802 and i need help because i believe it's a software problem.
When i was installing the latest cm12.1 nightly, after trying a few other roms, i also installed, by mistake, an old jb bootloader/bootstack.
As result the phone entered in Bootloop, but not a normal bootloop, on the screen start appearing some crazy interferences and then the phone boot up, but the screen not. The phone made sounds and the touchscreen work, but the screen was black/off.
I've managed to solve the problem with an unbrick method, but now i have a huge problem: the screen, on the rigth side, from the top to the botton has 6/7 black lines. I have no idea how to solve this and if is a hardware problem ... I've read it's an kernel problem, not hardware, but don't know how to solve the problem :/

I feel your pain
Hi mate
Same thing happened to me.
Background info: I had successfully upgraded to CM12.1 , was running fine for a few days then I wanted to update my TWRP, updated the recovery and just went to check that I had OTG cable support then boom, boot loop.
It didnt just loop it just loaded loaded loaded, then the screen made some funny sounds. and then shut down. I hard reset to recovery and reinstalled CM12.1 and was able to successfully exit the loop. but damage to screen had occurred in the exact same place, and method right side of the screen.
Tried rinstalling original jellybean software from my backup. no success, and also flashing other versions of CM12.1 nothing.
After some research I saw that this is a manufacturing fault and that this occured quite often. it appears that the best solution is to buy a new screen as it is the actual hardware that is damaged in the screen digitizer. I might be wrong, and I pray that I am because I want to fix it too. in the end I just bought a new note 4 (not note 5 as i wanted SDcard storage). Phone was 2 years old and a new screen costs a fortune. But i miss my little G2 and its super fast speed and simpleness. :crying::crying:
If someone else has the solution to this problem on the forum we are all ears.
Hey,
I've been looking around here quite a while now to find a solution, but I can't find one. So that's why i made this post.
My N-910C was running Sweet Rom 17.1 and Googy Max Kernel, everything worked fine. But after 3 weeks my phone starts to crash immediately after locking my phone, or after it automatically turns its screen off.
I've tried flashing the stock rom, that didn't work, after flashing it's crashing when it says 'installing system update' and after a few times it says 'No command'. After that I flashed Googy Max Kernel back on my phone and it boots, but when my screen turns off my phone will crash again.. My options in recovery are limited due to the fact it reboots after a while without any reason.
Is there anyone here that knows how to fix this? Or is it possible to do something to get it fixed with warranty?
Thanks for your help
Update: Tried to flash stock rom with the newest firmware(N910CXXS2CPB3_N910COXA2COJ5_N910CXXU1COJ5_HOME.tar) with Odin 3.10.7(with Phone bootloader update on), passed, when rebooting it said 'Installing system update', but before it was finished it said 'Erasing...' aaand a reboot again. But than it showed the Samsung logo animation and it crashed at showing the first 4 letters. After that I flashed Philz 6.58.9 to flash Googy Max 2.0, the phone now works, but is still crashing when the sreen turns off.
Hello,
I've replaced the display of my Note 4x, but unfortunately, the screen only works until it goes into sleep. This means that the phone stays black and I have to completely reboot it.
In addition, the screen stays black while booting into the recovery mode (according to adb it is in recovery mode).
Does anybody know what can cause this problem?
Thanks in advance

I had that problem in a different device (umi super) although I didn't have custom recovery (mediatek chip, worst phone ever). My solution at that time was updating os to latest version.
My opinion to you is try to update firmware files or try using miui developer build.

Thank you for your reply.
After reflashing the phone to stock rom, everything works fine.

Ok, so a weird kind of problem has popped up.
Firstly my device was stuck at Mi logo. I quickly flashed fastboot ROM (MIUI 9) through edl as my device is locked. It booted up correctly but when I lock the device (screen lock), the screen never lights up again. I can hear all the sounds and adb is working fine too but the screen doesn't light up. I have to force restart the device now and then. I have tried flashing MiUI 7,8,9 but the problem still persists.
Any suggestions? Shall I try custom ROMs?
