Lg g3 screen stays black after reboot, but responds to touch - G3 Q&A, Help & Troubleshooting

My wife's phone looked completely dead this morning, so I pulled the battery and then rebooted. The led did its usual start up pulse but the screen remained black.
Double tapping to wake, then tapping the centre of the screen where login field is, then tapping where the keyboard is, results in haptic feedback, but the screen never turns on from black.
Tried holding down + power to boot into recovery, but no idea if it works. No response from the screen.
Anything I can try? :crying:

Its the faulty motherboard chipset issue, same as me.

Take the phone apart and place a piece of plastic or something on top of the display ribbon connector underneath the battery. That solved this problem for me.
Seems to occur because the board in the g3 has too much space to flex etc in general usage.

[Q] Screen wont turn on after it turns off. ATT Tilt 2

Everytime I boot my phone up, it works fine up until when the screen goes into sleep mode. Once it goes into sleep mode I cannot turn the screen back on, it stays black. The keyboard, end and answer key lights show up when I press the power button but the screen just stays black no matter what button I press.
I end up having to either take the battery out or using the stick to press the reset button on the side in order to get the phone to where I can see the screen again. I have adjusted the settings to where the screen doesnt go into sleep mode and the screen just stays on but that drains my battery. I want to be able to have my screen go off so I can save power but if it goes off it wont come on again until I reboot.
I have done a hard reset. This problem started happening to me when I started using the Energy Rom but I've even flashed different Roms and the problem still exist.
Somebody please tell me what's wrong! I need help! This is a big annoying problem to have. Thanks.
is this problem occurring when you slide the keyboard out?
i had the t-mobile touch pro2 with this problem.
the screen would die when the keyboard was out and not come back.
if this is the case, what i did was...
well. obviously not open the keyboard fully.
but if i accidentally had.
instead of pulling out the battery, i waited...
till the screen 'naturally' went to sleep.
than i would pull out the stylus or press power button
and the screen would come on.

Yes the problem still exist even when I slide the keyboard out. Once the screen goes off, that's it....pressing the power button to get it out of sleep mode, sliding the keyboard, I press all buttons and nothing works. The only thing that "works" to get the screen back on is removing the battery or using the stylus to press the reset button.
When sliding the keyboard out the keys light up but the screen doesn't come on, also pressing the power button lights up the end and answer keys without the screen coming on.

so. whenever the screen goes out, period, you cant get it back?
or the screen goes out and cant get it back once you slide the keyboard out?
if it is only when sliding out the keyboard...
try not opening the keyboard fully on the right side.
on my rhodium, after that point, the screen goes out.

Yes, period. Also, you know when you put your face to the phone during a call and the screen goes off so your face wont press anything on the screen? It doesn't come back on from that either once I end the phone call, it just stays black. I'm assuming you don't have any other suggestions. This Sucks

This has to be a software issue but I don't know where to start. I'm surprised nobody else has encountered this problem. I've grown frustrated of this issue because I don't understand why it's doing this. I have had the phone for almost 6 months only dropping it once 4 months ago and it wasn't a strong damaging drop that would affect anything inside. I guess I'll just have to go last resort and call warranty to swap the phone out. Thanks for the help.
Same problem

My phone also dos not come back on, when I put it in out the sreen with the power button on top, or when the phone goes to sleep. Nothing can put it back on(opening te keyboard, pulling out the stylis, presing the answer-, windows-, back- and end button). I and up using a music players too keep the phone busy what's makes it operational. Cant really remember when this started happening exactly. My phone is at the moment loaded with a standard ROM. I used too have a custom ROM.
My TP2 does this too, although I only encounter the problem sometimes when someone calls. I answer and put the phone next to my ear, the screen goes black as it should and the phone just dies. I can't hear what the other person is saying and the screen wont turn on anymore. I have to take out the battery to reboot.
set light sensor to manual in settings. You have some bad or fragmented code causing the problem. Pretty common actually, many different reasons, but usually either a bad light or proximity sensor or software issue. Setting the sensor to manual should do it, if not, hard reset and allow the phone to fully set up before touching it, to allow full customization process to complete. Search my posts on SOD (sleep of death) for more information.
Funny this was brought up. Now im worried I just dropped 250.00 and have a new one coming.
Mine started with the ear piece quit working. couldnt hear anything except on speaker.
Anyway I started having the screen issue over a month ago, only way to get it back was soft reset with the stylus. Also when the screen was lit, I couldn't hit the power button to turn the screen off. At times the screen would be on 24/7 and I just dealt with it. The times when it decieded to go to sleep was when I needed the soft reset. Well long story short I forgot my charger one day at work and the battery died. after pressing the power button for hours with no response, moving the screen in all diffrent directions as I pressed the button.It came on once after hrs of messing with it. Well today it died again and I am fed up with it so out came the tools. Once I opened it up I noticed the ribbon that feeds the screen from the mother board was worn and torn. the ribbon slides everytime the keyboard is slid out and it rubs on both sides of the phone. I thought maybe mine was just a fluke and was installed wrong considering the phone being 10 months old but now I read this and see maybe its a common problem. The cheapest I could find the Ribbon was 56.00 so I didnt want to chance it not being the issue.

[Q] Frozen Screen

My LG Nitro will boot up, but the touch screen is not functioning. The power button turns it on, the lock screen appears, and notifications pop up in the upper corner, but it will not react to any touch.
It happened a couple of times before but a few battery removals did the trick...not any more...
It will not unlock...What do I do?
I searched around and it doesn't seem like anyone else is having this problem. Thanks!
Did you try a factory data reset?

[Q] Often unable to unlock phone as screen won't turn on when I try to wake the Play?

I've had this phone for 12 months (Typical! Just out of warranty! ), and I'm still running the initial stock ROM, however, all of a sudden last week whenever I took it out of my pocket and tried to unlock it, the screen stayed blank. Regardless of whether I use the power button or press Home, (or slide the gamepad out) it very often won't display the lock screen so I can unlock it. Occasionally it will display the unlock screen fine, but increasingly often it won't.
The phone is definitely still on, as if I press the volume keys I can hear it "Beep-BEep-BEEp-BEEP" as I push the volume at the side to turn it up. Occasionally after lots of trying it might come back and display the screen for me to slide-unlock, but most times I end up just taking the battery out.
Any ideas regarding what has caused this and what could maybe fix this? I've never dropped it, spilled water on it, or done anything other than it was intended so it's really puzzling and I'm concerned that when I receive phone calls I will be unable to answer them as a result.
Thanks in advance!
I guess it's the flex cable damaged.

Is there a way to tell for certain before I attempt to replace this? I just got a phone call and was able to answer it by dragging my finger across the screen, however the screen was off. So the touch screen is still functioning. It's not the backlight as the screen is definitely still "asleep" and under light you still couldn't see any pixels. It's as if the display is asleep and isn't waking up. I have a feeling it's to do with the phone's ability to slide open, but I'm not sure.
Thanks.
Touch screen still working so means the screen or the flex cable is damaged. But most probably is the flex cable because of the design, lots of people having this issue.
As the above poster said might be the flex but the whole LCD might be dameged hold it under intense light and and watch the LCD power on when the phone turns on if not well...

Note 5 with serious issues: Screen dim (Almost unreadable), battery icon center

I was given a Note 5 to fix. I do not know the history of the device. If a Android update was attempted or why it is needing to be fixed. It presented with a very dim (almost unreadable, except in completely dark room) screen. I have wiped cache and master reset the device. I can see that the powered off battery icon is center screen all the time and it is solid black. I cannot power it off via the normal power button but I can power it on. I can power it off using the power button + volume down. The touchscreen is responsive and not cracked or broken at all. The back, multi and home buttons react normally to touch and light up. When plugged into power or PC, it does charge and will show a red LED when charging and a green LED when battery is full. The sounds are normal as far as I can tell. I cannot get the screen to change when I swipe or press a center button. I was able to get a picture of a begrizzled man peering closely at the phone trying to figure out what the hell the problem is. So, softwarewise, some of it seems to be working. But, I cannot figure out the dim screen. Like I said earlier, there no cracks or even scratches in either glass, front or back. The bottom portion of the stylus is broken, but I was able to use a tiny phillips head to stick up in the open area and it working. I get a sound and vibration when it is removed and inserted.
Any ideas?

For some reason when the phone detects that the battery is under 5%, it will forcibly dim the screen until it is charged above 5% or plugged in. Maybe the phone thinks that the battery is at or below 5%. Have you tried plugging it into a power source to see if the screen lights up?

Update #1 - Somehow, without knowing how, I managed to turn on an Accessibility option for the phone to tell me what buttons or actions I have taken. Unfortunately for it is in Spanish. I guess I should have taken Spanish in high school...

Yes, I have plugged it to the wall, I have plugged it to my PC and I have wireless charged it. It seems to charge to full as the red LED turns green.

Dark area on screen ONLY after sleep

Hi folks!
I've got a very weird issue with my P-600!
Yesterday, I noticed a dark area in the left corner on the bottom of the screen.
At first, I thought a LED line was dead on the backlight panel. No surprises, it's a 10 years old device...
To confirm that, I rebooted the device expecting to get the same issue (dark corner anyway, anytime) but it became even more "bizarre": after getting into system again, the dark spot was gone but the device was unable to revive the screen after going into sleep mode.
No matter if the screen was put into sleep by inactivity time-out or by pressing the power button, when the screen became black, it stayed black.
But with apps still running in background: for exemple Spotify was still playing music.
The only way to get the screen on back again, was to force a reboot by keeping the power button pressed down.
After reading many posts here and on other sites, I found some talking about the "Android Black Screen Of Death" and some tutorials on how to fix it on Samsung devices. So I opened my Tab, unlocked all flat cables, waited 10 minutes or so and then reconnected everything.
Well, it did it but only partially: now I'm a in quite "mixed" and unexplainable situation.
The screen works again, I can put my Tab to sleep and get it on again just pushing the power buton.
BUT...
The dark area in the left corner comes back again, only after sleep mode!
If I reboot the device, the screen is perfectly enlighted in all its surface, but it will get again that dark spot in the corner after screen sleep. What the heck... ?
So it's not clear for me how to definitely fix it.
Should I replace the entire screen? The flat cables? The battery?
Any help to understand what's going on will be greatly appreciated!
