Hi.
My LG G3 D850 have some hardware issue.It is working i can receive calls but showes blank screen .when i tap on screen it lights up but blank.
I have replaced screen but it seems its problem in the board,not in screen .
I am also 100 percent sure its not software issue .
Kindly if someone had this kind of problem then guide me which component of the board is causing this problem.
Hi,
Attached picture shows a blue screen not a blank screen : symptom of a dead motherboard (defective GPU connection : no repair)

Hi all,
I've recently replaced my N7105 screen assembly. I am able to turn the phone on, but the screen remains entirely blank. However, it responds to touch and appears to be working - only no image is displayed on the screen.
I suspect I've damaged a component on installation of the new screen, or have incorrectly connected it to the logic board. The replacement screen was from etradesupply and I imagine is almost definitely not an official Samsung component - is their any chance of driver incompatibility?
I've demonstrated the problem and displayed the connectors in this short video:
[Apparenlty I can't post links! Video is available by searching "N7105 Screen Problem" on YouTube]
If anyone has any suggestions, I'd be very grateful.
Best.

Recently, I've got an issue where the screen will randomly go dark, but not turn off. I have chekced this in a dark room and the screen remains on, but it no longers registers any touch inputs nor displays anything on the screen. The screen remains dark until I turn it off and turn it on again. I tried a screen recording app and checked the video afterwards. It seems that once the physical screen goes dark, the video shows that everything starts to run very slowly. From this, i'm guessing that the issue is either the CPU is having trouble or the GPU can't render the screen properly, although the recording seems to show that the screen is still there, but just not shown on the physical device. I checked the CPU usage though, and it doesn't seem to show issues as it is not running fully with about half of the memory free.
I have tried reflashing the stock rom with this

and the probelm persists. This also wiped root access and i have not yet restored it.
Could this be a problem with the CPU/GPU or would it be a physical problem with the hardware of the screen? If the issue is with the
I was updating the phone LS991 and after reboot, the display was distorted. I rebooted few times with a hope that would fix the screen but now there is no display at all. The phone boots fine, makes sound, i can swipe finger and can hear screen unlock sound, but there is no display. The backlight comes on i can see but screen remains black, just no display. On boot there is not even the LG logo.
Anyone can please help? it was on Marshmallow 6.

I have an international model but I had exactly the same problem. I send it for repair, and they changed the motherboard. It's all good now, everything working good. I had sn505 now the new motherboard is sn602. Which aerial number you have??

Just disassemble the phone yourself and see if the connectors are well connected,reconnecting got the job done on my case
I wake up today picked my phone and it was like that ( screen flicker / shake a bit from the top , much noticeable on white color ) I thought if I restart it might fix but didn't help . the flickering was also on when booting . when I first unlock the phone the shaking was on the whole screen but then after unlocking it disappeared and stayed on the top side like 20% of the display also it's less on the black color . didn't try to wipe or anything as I thought it won't do good so what is that actually ? and is there anyway to fix or maybe prevent it from spreading to the rest of the screen ? that is hardware issue right ?
edit : somehow I noticed that the issue is gone when I use chrome browser !!
