This thing is a month old and I really hope I can find a way to fix it. It is rooted so I doubt I can get a replacement...
I've seen other people with screen malfunctions where it shows weird colors after booting, but mine shows nothing. The Samsung boot animation doesn't show, nor does the ATT boot logo (although the sound plays). I can still use my phone by guessing where to touch and everything works fine.
Are there apps that can (with super user access) somehow disable the screen?
Is there a way to factory reset without being able to see what is on the screen? I tried the "Volume Up + Volume Down + Home", but the screen doesn't show anything.
Finally, is there a way to reset the ATT Galaxy S4 via Kies? I haven't been able to find one.
I'm guessing this has to be hardware since the boot logo doesn't show. Surely even if an app disabled the screen, it wouldn't be running before the logo appeared.

If the boot logo doesn't show (not the boot animation, but the very first logo when you first power on and it vibrates) then it's hardware. If the screen goes out after that like at the boot animation, then it could be that you messed up or something messed up a system file. This happened to me when I didn't set the permissions on my build.prop, it gave me black screen with blue LED and simply fixing the permissions in Safestrap fixed it.

So as the title says i currently have MIUI 1.6.10 demonSPEED v1.1 ROM and it is not booting, just completely unresponsive to everything i could think of. Im just throwing this out there to see if this has happened to anyone before or if there is a way of fixing this issue. I don't believe it has anything to do with thederekjay's rom just some unfortunate event. Anyway i fear it is possibly bricked and that i am gonna have to shell out the $150 to get a new mt4g from the insurance. Details follow...
So have had this rom for about a week now and has been working great. However this morning i was on the browser reading the news and it became unresponsive. After i let its display turn off (i just left it alone) i used the track pad to wake it. It was slow but it did show me the lock screen. When i attempted to unlock with a swipe down i felt the vibrations but the slide lock didn't budge. I then tapped the power button to turn the display off and tapped the power button once again to turn it on but nothing, just stayed black. I tried a soft reset by removing the battery, placing it back in, and powering back up. When i did so the t-mobile mytouch 4g boot image w/ the white background came on then went to an android image (lighting up a through d, looping) but then it just remained at the android image for five minutes! So i tried a soft reset again but the same thing would happen, act like it was gonna boot up completely but then gets stuck at the android image. So then i tried removing the battery and booting into recovery (via power, vol down, trackpad) that time the t-mobile mytouch 4g image would appear but after that the screen went black and after that every attempt with either the soft reset or boot into recovery wouldn't do anything at all, just a black screen as if the battery wasn't in at all. Its been like that all day and i can't figure it out so if anyone knows some info i would greatly appreciate it thanx
Recently purchased S4 SGH-I337M locked to Bell. Before I paid for the phone I installed CPU-Z and Genuine Galaxy apps just to make sure it is not fake S4. Both apps showed the phone is genuine S4. The phone looks genuine inside (I checked the motherboard, camera, etc) and outside (thin frame, power light far from the speaker, etc). The phone is running offical ROM.
However, I can't put the phone in download mode using buttons. Tried all possible combinations so many times. I can put the phone in download mode using ADB but even then there is nothing on the screen. I was able to flash the latest official Bell firmware via ADB hoping the new flash will enable download mode. No luck. Still no download mode. When holding volume down, home and power buttons the phone vibrates, I let the power button go and after that nothing happens. The screen stays black. I tried the combination without home button, just volume down and power button. Still nothing. When using the phone all buttons work properly. I am able to put the phone into recovery mode no problem. Recovery mode displays late (I need to wait for 7-10 seconds) but it looks and works just fine.
One other thing that is also strange - there is no "Samsung Galaxy S4" logo when the phone boots up. The phone stays black and the first thing it shows is the Samsung booting animation.
Just wondering if anyone has seen something like this before?
What could be the issue here?
Thanks in advance for any help/suggestion/advice.
I apologize if I posted this in a wrong category.
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$.

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.

hi there everyone, i have verizon variant of the s7 edge. yesterday my screen started to shutter when in an app and the eventually would go black, although the phone would still be on because the back and recent apps buttons on the bottom would still be lit. ive read on line and watched videos saying to do a hard reboot, didnt work. as of now it is completey black nothing will show. the lcd still works becasue the boot animation will still show. i am not able to get into recovery more or download mode. but i am able to get into maintance mode, ive tried a factory reset through maintance mode and didnt work the phone would just boot into the black screen. the phone is completely stock, no root or anything. Any help is appreciated.
Try to use smart switch and do an emergency software recovery.
Also, what does it do when you try to get into download mode?
When i try to get into download mode by using volume down, home button, and power, nothing happens its another black screen. Was hoping I could get into download mode to try to reflash the stock firmware. Also I can't use smart switch app because the screen is completely black when I turn it on.
