My opo goes to a blank screen after the oneplus logo appears during startup. I've tried flashing COS/color. However, when I try to reboot it just goes back to the blank screen after the oneplus logo, as though nothing has changed. What can I do? is it a proximity sensor issue?
I can boot into FASTBOOT but when i try to boot into recovery same black screen.
Some background info:
sometimes the the display turns on for a few minutes but again goes back to black screen.
I've been unable to power off the phone completely for a couple of weeks. Powering off the phone with the power button always resulted in an automatic restart.
i am able to interact with the screen the gestures work but i am not able to see any thing.
I've have tries fully draining the battery and charging again but same issue.
this started about 3 weeks ago.
Thanks in advance for the help.
Have you tried re-flashing modem adequate to your software?
Anyway I think you should contact RMA with this issue

Yes i have flashed the appropriate modem. i read somewhere that cleaning proximity sensor solves the issue, i'll try it and update here.
I want to keep RMA as the last resort, its takes too much time.

ok, weird issue.
Yesterday I came back to my TF having left it inmy bag for the day, and it would not turn on at all.
I tried various things and then decided that the battery must be totally dead.
I left it to charge over night, and come the morning was able to watch it booting.
However once It finished boot it goes to black screen. Pressing the power button sometimes gives a flicker of backlight and then goes blank again. sometimes it even gives a glimpse of the screen.
Plugging in the power sometimes gives a longer blink of the booted ROM.
I have tried a cold boot, a full data wipe and I have used NV flash to fully reinstall the ROM (Prime 1.8)
After the full reinstall I go through the Google initial setup process without a problem, as soon as the rom boots I am back to the flicker of screen going off..
Does anyone have any ideas??
Still got the problem, does this sound like hardware to anyone else?
if the screen doesnt work during boot it is hardware problem. flash ur rom again or wipe it

Screen works fine during boot
Done both of your suggestions unfortunately, as I stated in my original posting.
I am going to try going back to Stock, and assuming its an app NOT restore any during the rebuild process.
Hi all !!! Sorry for my English but I need your help
I commented what is happening with my phone N5 (which for good and evil is always stock without root or anything, with corresponding OTA updates.)
1- Yesterday afternoon at lunchtime while reading a book in playbooks, I notice that suddenly disappears one line and then appeared intermittently. I close the app and noticed the same thing happening on the screen menu. I shut down the cell and turn on again and I thought it must be an application be kidding. But still does.
2 Also yesterday I happened to change the security on the phone screen. After a while of normal operation, try to turn it on the screen with the button, nothing, the screen goes "black", with light and retrolight turned on but no picture no nothing .
Called the cell to see if it works or is turned off and the phone rings but the screen nothing. Try turning it off and on again by holding the on / off / lock button and the phone restarts, but the screen nothing. In one such attempt to do the above it is seen that managed to turn it off. And I get it on and do a normal boot, except that the picture of my screen is changed to the original. Change the lock screen which was previously using (slip). And it seemed that out or some conflict with the lock. In one of those again pressed the ON / OFF / lock as would normally and it starts all over again.
After I magically back to life, I want to make a full wipe as I think it should be an app that is doing some conflict or something. BUT ....
3I turn off the phone and then press the keys VOLUME UP / DOWN and ON / OFF is normally off, squeezed the first screen with the options but options RECOVERY / BOOTLOADER appears in red I choose RECOVERY give the ok with the key and .... andriod robot appears with the legend below that says something (I do not remember well) without or without controls options appears. So its seems thatI dont have recovery.
After that keep pressing the key ON / OFF and the phone turns off and / or reboot normally. All this I did it again to see if the error reappears and looks that I do not have recovery.
The failure of the screen is increasing. I dont know if they are separate problems or is it all the same problem.
Sorry if I was too long but I need the help of you.
UPDATE Now it seems that the screen died, since I do not achieve to turn it on as before, the light and the retrolight its ok. The phone receives calls and notifications but the screen stills black.
Thanks all.

sometimes things just "derp". itll happen more often if you dont reboot your phone often. also, your phone will be a little bit more responsive if it gets reboot once a day or two.
RMA or fastboot it back to stock, if the screen doesnt turn on afterwards then it looks like a hardware issue, open device and reconnect the display.

I think too that its a hardware issue. I already see on you tube problems like mine.

Hello! I have a stock Android Lollipop 5.0.1 Nexus 5 and for the past week or so I have been experiencing a weird issue.
The device randomly crashes. By "crashes" I mean the screen goes black, but the backlight is still on (it's a lighted black). I can push the power button and it will turn completely black (locked) and if I push it once more it turns lighted black again.
To get the device back into usable state I have to keep the power button pressed until the phone resets. Sometimes I keep it pushed for a full minute and nothing happens, sometimes 10 seconds are enough. Sometimes it will go through the "Google" logo and then stay in the lighted black state until I finally manage to reboot it again. Sometimes it crashes again right after it boots up.
It's weird because a lot of the times it's ok throughout the day and then when I go out in the evening, I take it out of the pocket and I see it crashed. Sometimes it crashes while I actually use it.
Last night it started doing something else: instead of lighted black, the screen is filled with static noise. It doesn't move or anything, it's a still image. Today, when a crash like that occurred, the screen glitched first (random lines on the screen, some parts got moved, really weird). I will get some photos if it happens again.
The problem is that I can't identify what's causing it. There is no particular app or action that I do / use that triggers this. It also doesn't seem to be movement-based, as it sometimes happens while it's sitting still on a table.
I updated to 5.0.1 about a day before this started happening, but I'm still not sure if it's software or hardware-based.
I tried a factory reset and booting into safe mode, none of these helped. I will only consider flashing a custom ROM as a final resort, because I'm not sure if it voids the warranty.
PS: the device is still under warranty, but I'm away for the holidays and will be until the beginning of the next year. And I'd like to have a usable device, especially while I'll be on the road.

I have none of your issues, try booting the device in safe mode and see if the problems still occure. It must be a or multiple downloaded apps that are causing your issues. Or try a data factory reset and restore/download your apps one by one amd try to identify the culpritt.

I said in the post that I tried both of those things. The crash occurred seconds after booting in safe mode and factory reset did not help either.

Flashing the 5.0.1 factory image in fastboot should fix your issues. Or try flashing system.img first, maybe thats enough.
Same issues with my Nexus 5

I am experiencing SAME exactly issues in my N5 with 5.01 and 5.1 . EXACTLY... you are not alone
Seems a software problem (third party app ?) , started in 5.01 and now is in 5.1 , of course system and boot images where flashed with fastboot, so no solution using
Stock, Rooted, using Nova Launcher - Smartwatch 2 - Google Cardboard - Chromecast and many apps.
But started ..if memory helps .. after installing Cardboard 3D apps.

My phone had an issue with the screen. I went to the LG service and they replaced the screen entirely, so that's that.
again and again...
i'm in the same case... I don't have any clues or solutions, i'm just wainting like a dumb... I don't know what to do, i always have to make the thing with the power button and the lower sound button to make it show the boot screen, but it glitch after few seconds... PLS HALP
Greetings.
I've recently been struggling with a problem with my Galaxy S6 and I've searched far and wide on the interwebs for a solution, with no avail.
You see, whenever I turn my phone on, or wake it up from the lock screen, the screen flickers one or two times, but doesn't always turn on.
They keys are active, touchscreen is active, but no image.
Sometimes I have to try and unlock my screen two or three times to get an image, sometimes it turns on after the first flicker.
An example of what I am experiencing is at https://www.youtube.com/watch?v=CyiDgpUSkaE
[edit] Another example is this: when switching the display brightness, the screen goes to crap and starts flickering like crazy, and at minimum brightness text goes unreadable and small (video) https://www.youtube.com/watch?v=HIMFaCy_KVY
I am not rooted, everything is stock FW, I had android 6 stock and recently upgraded to 7 stock OTA and the same issue persists.
I cannot access download mode or recovery because the screen won't turn on. Only time it turns on is when Android is booted. Even when booting, the blue led flashes because the device is booting but I have no image.
Please contribute with some ideas, I cannot wipe cache from recovery because I can't see anything even if I try to boot recovery (or download).
Thank you in advance!
Did you resolve this issue? If so, how? Mine started to do the same after a short fall. My initial thought was hardware but I can get into recovery and the screen functions just fine there.
It is the second time this happened. Last time it fixed itself after half an hour.
The screen is always pitch black and the device stays warm.
Most of the time it is boot looping with a black screen, the 5G led on the back keeps blinking in different colours. When connected to a PC, in Device Manager I can see two "LG-V500N", then it disappears after a minute, and comes back, repeat.
Sometimes the device boots and stay booted with a black screen, I can tell the device is on because it is listed in "adb devices". Unfortunately I don't have any authorized device to connect to it via adb.
I am not sure what I can try, I have pressed and hold power + vol down many times but the screen remains black.
I also have trouble switching off the device, it seems to either stay on or boot loop.
After letting it rest for a few hours, switching it on shows this screen, with a white/gray line at the top of the screen, and after 5 seconds it switches itself off again.

Get into download mode by powering off the phone and pressing volume up while having it plugged into a PC. Then find a guide to flash a kdz lgup. You will probably lose data or have already lost it

It seems the phone will not stay in download mode for more than 5 seconds, it powers off after showing the big download mode screen for 5 seconds.
I will try to leave my phone on the charger for some time and then try again.

I managed to get the device to enter and stay in download mode, however the screen stays pitch black and I am not sure if I should continue flashing.
Would you go ahead and flash it if you were me?
The device is currently on Pie, I will probably try flashing a Pie KDZ first, before an Android 10 KDZ.
Sometimes there is a brief moment where the screen comes on, that's when the LG V50 logo shows before entering download mode.
Did an UPGRADE with V500N11r_00_KT_KR_OP_1017.kdz, which should be the same firmware that the device is already on, it flashed successfully, didn't seem to help, screen remains pitch black.
Did a REFURBISH with the same kdz, didn't seem to help either.
The phone seems to continue to boot loop after the REFURBISH flash. When connected to PC, LG-V500N shows up and then disappears repeatedly. Sometimes I can hear a sound effect being played from the phone, sounds like it has booted and the sound probably came from the initial setup screen.
Seems the phone has stopped boot looping, it is on the initial setup screen. The screen remains pitch black but it responds to touch.
Not sure where I can go from here.
Edited:
The screen has come on briefly once for a few seconds, it is on the initial setup screen. I only had time to switch the language to English, then the screen went black and the device seem to have crashed (no longer makes sound or vibrate as I randomly tap on the screen)

I think it's some faulty hardware at this point. You've tried everything possible as of now.

Hi! I bought an LG V50 and exactly the same things you described happens to me, the screen starts, it shows the logo, but then it goes completely black, but phone starts, sounds are heard and the touch screen work. But not image, screen is black. Could you find out what hardware defect it is? It's the display module, or will it be the motherboard? Thanks
Nope, I have sold the phone as parts.

I got a samsung Note 10 doing this! Took it to local shop! he sprayed some liquid near the proximity sensor area and I saw my phones screen came back to life ;while hiding it he was Telling me if he can repair the screen without changing it he"ll need 20$.. I laughed and told him not interested to repair....
