[Q] LG G2 often run into black screen but app still running - G2 Q&A, Help & Troubleshooting

Bought a refurb unit of LG G2 from ebay in latest deal, the black screen appears unregular ranging from webpage browsing to light gaming and youtube, when i tap on the screen i can still hear the sound, like the sound when i return from current app, or the youtube videos, when double tap to lock or unlock, but only completely restart the cellphone could solve the black screen problem.
on the very first hour when i open the cellphone , i had 2 times of black screen before i even install anything, on that very first day i had about 7 incidents like that. After that day and battery is charged, this problem did not appear so often, but still 2 to 3 times a day . I tried factory reset yesterday, but 2 hour after that, run into black screen again.
I love the screen and size but i found myself losing interest after days gone by because of this problem, is there anything i can do to detect and fix the issue before i send back the phone to QualityCellz

Screen goes Black - Stuck

I am having this problem for last 1 week or so. My Touch HD screen won't turn on, stays black but in the background it's working. it's responding to touch gestures. vibrates when i press call,end, home buttons. I have installed My Mobiler, so i can see the screen in my PC but it's all black in phone. Sometime it comes back in few minutes and sometime it takes hours. I have tried hard reset, different roms, stock rom, stock spl, updated radios but nothing so far. Is it a Software issue or is it hardware based?
Thanks in Advance.
anyone?.......

no i don't think i have ever dropped mine.
I have tried everything i can think of, it just started happening about 10 days ago. It's getting worse now, screen stays black for hours, even restarting the phone doesn't help.
This actually happened to mine as well, and I was very close to sending it back under warranty. However I removed the battery & SD Card overnight and tried phone again. This time it rebooted fine with screen working properly. Try this and see if it works.
The problem with the HD is its not very well put together and a number of people have had issues with motherboards & faulty/loose connections with the screen resulting in the symptoms you are experiencing.
If has since happed again and I decided I couldn't wait so I took device apart and fixed loose connections again.
Under no circumstances should you try this unless you are 100% comfortable and know what you are doing as opening up device will void your warranty

Htc Magic strange screen problem

This is my first post, so i want to say hello
sorry for my english, it isn't perfect but i hope you'll understand me.
I have strange screen problem. It has been staterd several days ago.
During normal usage (typing, surfing and etc) screen in my phone suddenly gets dark, but when i look on the screen in place where is strong light(for example near lamp) i can see that all stuff is still on the screen. It seems that this is the under screen LED problem.
Problem appears totally randomly, sometimes a few hours everything is ok, and after that screen suddenly gets dark, when i type red button two times(lock and unlock) the LED's are lighting,but only for two, three secounds after that screen is dark again. When i leave phone, after several minutes the screen turn on automatically.I tried several roms, old and new radio, problem still exist.I guess this is HW problem, but i just want to make sure before i take the phone to the service.am I right?

This happened two days ago with my wife's S7 Edge. She was using it to text me about dinner plans after work, her screen shut off, and it wouldn't work for several hours. The thing was getting very hot. When she was home and charging the phone the screen started working again for a little while, but with several green stripes down the right edge snd aa flashing horizontal band of grey near the top overlaying the screen image. Then when I tried plugging it into my computer to use Samsung's Smart Switch to roll back from the update she had accepted while at work the screen died again. It has not come on since, not even the stripes, and blue or red LED lights once in a wwhile at random. I managed to use Smart Switch to wipe the phone's memory. Then the program took several hours to download something very slowly and install that - a whole new OS update? That completed, and now the charging LED works correctly and the green stripes and grey band are back, flashing rapidly when powering on. Otherwise no screen function.
She is now trying to find a new phone, but definitely NOT a Samsung. This S7 Edge has already had the screen replaced once, just before the first year warranty ran out, as it did almost the same thing - in March the green striping (plus pink) appeared along one edge and the battery was running out very fast, the phone overheating so much that she found it uncomfortable to hold. We argued with Samsung a lot until they replaced the screen. Something is VERY wrong with this model. She's considering an LG. What a waste of money. One would expect a thousand dollar phone to last longer than this.
I am facing what I think to be the same issue with my son's phone. Green line down right side edge. Screen turns on for a second, then black screen. It's on, but can't do anything. Did you find a fix for this?
No. Today I gave up and took my wife's S7 Edge to the authorized repair centre. They say they'll run a diagnostic for $25, and if the screen needs to be replaced it will cost $385. Brilliant. If this thing gets fixed I will be running custom ROMs on the phone, probably an RR, as it seems Samsung's OTA updates kill phones.
Turned in out the authorized repair centre for our region, Acura in Surrey, BC, went ahead with the screen replacement without our authorization. I specifically said in a note given to them at the time that they were to ask first. But they didn't bother. My wife decided she liked the phone enough to pay over $400 to get it back. It's been working for a few weeks now. Hope it stays working. At this point I have a strong feeling that the S7 Edge was a poorly made device, at least some batches. The reports of these screen failures are just too common.
Check if your screen still alive or maybe connected correctly, here is a way to do it:
1- plug it in your computer then start smart switch
2- dail *#7353#
3- you can now test any thing in your phone
4- search for the TSP
5- try now to touch your device screen
If it display in the computer that mean the touch is working but the screen is not
If the toch is not working you have to check the cables if its connected correctly inside your phone
But if you have warranty don't waste your time and let them fix it, and don't forget to backup your files

V20 Black Screen

Woke up this morning and started using my phone, noticed that the screen became unresponsive for a few seconds at a time and then I saw some gray horizontal lines.
Did a battery pull and restarted the phone, however, the screen is completely black and I can still hear the boot sound.
It requires a pin to start completely and I can feel the vibration when I touch the location of the back button (the only navigation key available on the pin screen).
Since this started happening I have tried restarting several times and I have seen the "LG splash screen" once, it freezes, the boot sound plays and the screen goes black once again.
The phone is unrooted and has never been modified any at all. It is the US996 variant.
Has anyone ever faced this issue? Could it be the display itself and maybe a replacement LCD will fix the issuse?
UPDATE
Got past the pin screen and think the phone has fully booted, fingerprint scanner works, I can touch the navigation keys and get feedback and I am still getting notifications.
However, the main screen is still blank and the second screen shows the time surrounded by static surrounded. I have attached a photo.
Sounds like a hardware issue.

Hi Have you fixed the issue?
Hi
it looks like a corrupt bootloader,
Was it rooted? try to press with the phone off volume + and plug in the usb to enter in download mode, if you enter download mode go back to factory

Had to send it in to LG to have it repaired
Oddly enough once it was returned the problem reoccured a few weeks later after using an aukey quick charge3.0 charger that I had. Which was when it happened the first time but I didn't make the connection until the second time around
I got rid of the phone though
No more LGs for me, I haven't had much luck with them
Throw that charger seems like or the cable or the charger itself gone bad ,one charger killed 2 of my phones not diferent brands

Touch stop working after turning off and on the screen.

I've been using the PH-1 for a year and a half and its great, but a couple days ago i would unlock the phone via fingerprint (as ussual), it would unlock but the touch wont work, so i factory reset the phone and still the same, remove the case and the screen was loose (almost complete), but the cable was well connected on both sides so i got the screen glued, but still the same.
Im using Android Pie (from day 1) with March update (updated like a week ago), in order to use the phone beyond what Google assistant can do i have to reboot the phone (using power and volume buttons) to get the touch to work again and dont let the screen go off. Sometimes after rebooting the touch works even if i turn the screen off and on, but i think its just luck.
You guys think it might be a software issue? or hardware issue? because i don't live in the US or CA, so i would have to wait a couple weeks for the screen to get here and i would'nt be able to return it in case its not a screen malfunction.
I really don't wanna change my phone, i love the PH-1.
EDIT: i just replaced the screen with a new one from fixez.com and the problem persists, i think april's update broke something. is there something i can do to check the software? Pls help.
I rooted my phone and almost the same thing happens. I turn off the screen and turn it back on and the touch is unresponsive. Howver, ONLY the apps left on screen are unresponsive. I can still pull down from status bar its weird.
Update 1: I saw u mention fingerprinting. I removed mine and somehow it seems to have stopped. I'll use it for about another day or 2.
Update2: Well it doesn't. If my screen times out with an app open. The app is unresponsive upon waking.
