HELP!!! My moto g4 plus starts but the screen remains black. - Moto G4 Plus Questions & Answers

Hello, I need your help, my smartphone g4 plus broke the screen and changed the whole including the frame but when mounted the phone starts (vibrates and you hear the tone of Motorola) and the screen remains black.
The problem is that I have data to recover and I can not access the inside of the phone via pc, I do not see the bootloader menu.
The funny thing is that you change only the screen (without the frame) and without finishing installing it if it started perfectly as shown in the video but when you finish sticking it on the frame and finish the assembly does the same.
video test.

please help! hermes white screen (not normal)

my htc hermes (herm100) does the occasional white screen here and there, but i dropped it (like a foot away from the floor) and it almost always white screens, the phone will come on, the ATT logo (like the bios thing) will load up and everything, but as soon as its about to play the 3g animation, the screen fades to white, but everything works, the 3g sound plays, the screen responds to touch, etc. the screen also displays perfectly when i start to do a hard reset, the screen comes up to press r and all that, then space to boot, then the screen goes white again. i've taken the phone apart, checked everything out, made sure the ribbon cables and such were set properly, everything. If this helps, my camera had stopped working the night before...when i would click the camera button or started it from programs, it would say somethin along the lines of "the camera could not be started. initialization of camera failed" and i was actually gunna be asking about that right now til it uber white screened. Any help is appreciated.

Update: Took Hermes apart nad reseated the d-pad ribbon, everything seems ok. Thanks to Mike channon for the Disassembly manuals. Hope this helps other people.

Display gone blank, touch and sound working fine, vibrations are fine

Hi,
It would be very kind of you if I can get some help here.
My Yu Yureka got a little wet in the rain but was working fine. A little while later when I wasn't in the rain any more I tried to use my phone. The display flickered for a minute or so before it went blank. I dried off the phone and tied restarting the device but I saw a vertical bluish strip before it went blank again. Now whatever I do, the display doesn't show a thing. I can receive calls, listen to all sorts of sounds the phone makes in general, feel the vibrations and even unlock the device while the screen is completely blank.
Could anyone suggest a solution to this? I would be very grateful.
Regards
SM
Your display is dead. There is no reviving it. You have to get a new display assembly.

LG G2 802, New Display and Front Body,Phone call screen gets black

Hi there,

Problem after the screen change

I changed the display , the touchscreen of my one plus. The screen is a lcd and not amoled but works perfectly. After 3/4 days by using it , it started to give me some problems and the only way to fix it is going on the twrp and go back on the old backup. The duration of the problem is not the same but change. This problem comes up when i try to open an application, unblock the screen or after ending a call. The screen just go off and doesn't turn on again, if it gets restarted it will work again but once i get the pin screen it only show it for 1 second and then the phone just turn off auto.

Click to collapse
Could be proximity sensor getting blocked. My friend also replaced his screen with an LCD panel. This problem occurs when he calls anyone, so to restored back he uses power button and screen switches on again.
