Phone screen is black, but phone still "works".. Cannot get screen to come back on!

Phone screen is black, but phone still "works".. Cannot get screen to come back on!
I have no idea what happened, 5 minutes after being in my pocket I pulled it out and the screen was un-responsive.
The notification light is still on, power light, etc. The power button works, I can push and hold and reboot and the two bottom buttons on the phone light up. I was able to "swipe" my password and it vibrated and accepted it, I am getting vibrate notifications too. I just have a black screen and I can't figure out what to do!
I am rooted, but I haven't had any changes to the phone in a few weeks since I had rooted. I tried using http://forum.xda-developers.com/showthread.php?t=2786395 but I cannot figure out how to get the device to show up in the program to use.
I am at a loss on what to do...

No Samsung logo if you remove the battery for 30 seconds, replace it and power on normally?

Nope, no nothing. No logos, no screen flicker, no colors of any sort - just black. The LED goes blue as it boots up, etc, so I know it does power up.. and once it is done I can even swipe my password and it gives the feedback vibrate..
Just in case this was an issue with the root and whatnot I flashed the stock with Odin and I still am getting black screened.
I contacted VZW support last night, and the chat rep told me they would have to just replace the phone. I am guessing this may be a hardware issue.

Yea if there is no logo whatsoever when you first turn it on, it sounds like a hardware issue, not a ROM issue
I forget exactly which logo shows first (S5 I think) that isn't part of the ROM afaik, the Samsung animated logo is the ROM, so if you don't even get the one before the Samsung animation, doesn't sound good
Is it the G900F? If yes, the only thing I can think that might possibly work, is this

Don't use unless it's the G900F

I don't believe it's G9000F... and I am fairly certain now that it isn't a software issue since everything else 'loads', just not my damn screen.. lol.
Thanks for your help though

The reason I posted that link, is, if the bootloader has corrupted, it is possible you won't get any logo at all, and that debrick image basically tricks the phone into using the MicroSD card to boot into download mode from, where you can recover the main storage
It should tell you under the battery which model S5 it is
If the screen doesn't even light up, then it sounds more like hardware
See if this gives you access

It is connector issue.
Either connector is slight loose or if not then need to Change the connector.
My one has same problem.
Solved for less than 10$.

D802 screen not showing anything

Hello, I have D802 16gb phone and just started acting very wierd.... Firstly I do not drop it or drop to water or so ever, I protecting my phones. So, one day screen just go black, like went to sleep but blacklight working I can see, but nothing showing up, when touching I can hear touch sounds its like screen started not working or disconnected something. After a little time its started show again but after a few minutes of useage again screen went black, again backlight was working... So done hardreset, then tried unbricking it with flash tools and ksz files. But even when I power up phone, sometimes I can see LG logo, sometimes I cant, it booted after setup and I can hear with beeps of touch thats it gives me first time setup... I have another LG G2, so I know where to press, but nothing appears, just black screen with backlight... any solutions? I can try dissasemble phone if anyone can lead me through what to look for :/

I tried little bit dissasembly, reconnected displays connectors but no luck I cant believe that screen can just die on useage...

intresting thing... when I press vol Down and power button I got LG logo, but then nothing, just going straight to booting... Cant even go to do hard reset...

Can you get into downloa mode . VOL UP and connect usb cable.

I think so, because I tried reflash stock from ksz file with flashtool. Flash OK boots to first user setup but no image, just backlight... Tried holding very long power button or cleaning connector , just googled it, but no luck... now sometime with voldown and powerbutton holding I can get LG logo first, but then nothing, but it also does not appear everytime.... its like I have to wait some time when phone turned off to see at least LG logo :/

Samsung s5 black screen

Question 1. This just happened right now my s5 is starting up and sometimes it shows the s5 startup powered by android sometimes not after that it proceeds in starting up with the usual sound effects but the problem is the screen is just plain black. Now i believe my phone is proceeding to the homescreen cause i tried to ring it and it did plus my ringtone music played. I tried pulling the battery multiple times and start the phone but still same result. I also tried the taking the battery off and pressing the power button for a minute. also tried the safe mode, but none of them worked. What do you think? is it a firmware or a hardware issue?
Question 2. Im still not sure the cause of the problem. Because of the black screen issue i I wanted to backup my files saved in the phones memory. However my phone is locked through my fingerprint and I guess because of that when I connect my phone to the pc im unable to access my files. Is there anyway I can access my files through a pc and unlock it using my phone's fingerprint alternative password?
TIA

If the initial logo sometimes won't show up, it sounds more like hardware as that is not part of the ROM
If your phone is secured by fingerprint, wait for it to boot, press the home or power key to wake it up, then swipe like normal, if it's just a faulty screen, the fingerprint swipe should still work

hey thanks alot swiping the through the black screen unlocked my phone. so do you think it is a hardware issue I assume its the LCD?
but if ever the LCD is broken , the finger scanner should also not be functional? or im wrong?

The finger scanner is a separate button (Home button)
There are two parts to the screen iirc, the digitizer (Touch) and the panel itself for displaying, could be just the panel if the digitizer is still working
You can use this to control your phone without a screen, might help

i'm experiencing the same problem again. Before I guess after 40-50 restart I was able to open my s5 with a screen, but now it happened again and the difference is that when I boot it the "Samsung s5 powered by android" rarely shows and it will proceed until the home screen with a black screen?
i have already removed the battery, charged it, changed battery, boot it in recovery and safe mode but still all i'm getting is a black screen.
Any idea how to fix this? Is this a hardware issue already

Hi kenchii17
As you didn't provide answer to @*Detection* 's suggestion for backup, here comes another:
[TOOL] Tickle My Android
To get rid of all this inconvenience, I would suggest a complete reinstall. Clear everything through Recovery and then flash a new Stock ROM via ODIN.
Nice regards.

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

H870DS Stuck on Boot Screen, not Rooted

Hi guys,
Yesterday my G6 started acting weird yesterday. I pulled it out of my pocket and it was just on the boot screen (reads: LG G6 Thinq). I waited a little bit, but the phone did not finish booting. When I do a soft reset nothing happens just returns to that screen, and I also cannot factory reset because the phone freezes after clicking yes. I've downloaded both bridge and up, but neither detects the phone. I put my phone in download and it doesn't show up in the comm ports. I really don't know what to do at this point, and I could really use some help. I don't really know what else to try.
Thanks.
