Black screen but phone working - Galaxy S 5 Q&A, Help & Troubleshooting

Hello, i have a Samsung GS5 with a problem.
When i boot the phone, it shows the android screen for 5-10 sec. then it REBOOTS, make a VIBRATION, wait 1 second, make ONE OTHER VIBRATION and phone BOOTS but without LCD on. Phone works (i see button lights, sounds, touch is working),
What i have to do? I even tried to pull out battery and press power button for 1 min and then put battery but nothing.
Thanks

UP!

Install a different ROM. Like lineage os. That's a pretty big bug in your software.

[Q] Power button stop working

Hello, recently my phone has been having issues. The power button stopped work, it started first when I would unlock my phone, it would give me the power down screen then a few seconds later it would shut off.
Now it wont turn on... I have to pull the battery out and then put it back in then it shows the samsung logo and shuts off. To get pass the samsung logo I held the volume up button and then it will start up. I can only use my phone when I unlock with the camera which is very annoying.
I have tried just about everything and I have scoured the web to look for any sort of solution. I have hard rest, and I even tried flashing it with a rom. But the phone just shuts down.
I hate being a pain, but is there any solution?

Sounds like a hardware problem. Are you under warranty?
unfortunately, no I am not...

Luckily, I think the button is easy to change and it's cheap. But I'd go to a phone shop to confirm first (like this one in US - no affiliation, found via search).

Hi im actually getting the exact same symptom. Did you ever get to fix yours??

[Black Screen] S3 neo, READ and suggestions are welcome.

Hello everyone,
I have an S3 neo, it's 6 months old. About 2 months ago i started checking in this forums, and then i flashed cm12, and started adding custom roms to my phone. Everything was well, phone was working fine, and so on.
One morning i woke up and my phone went off, and when i turn it on, it's black screen. I restarted few times, took out memory card, and poof it worked. Was all good.
I left it like that and next morning it happened again. And since then i tried all the ways, like take out battery, hold power button 1 min then try to turn it on after few minutes, and so on. Nothing worked. Pulling out memmory card or sim card didn't work either. It's like this for almost 2 weeks i can't use the phone.
I cant get in download mode or custom recovery i i don't know why it won't react on that. It turns on each time like normally, led notifiaction works, the lights on home and back button works, only screen is black. I can unlock it, and such things but cant see anything.
I even succesfully did a factory reset over play store from pc, but that didn't help either..
Biggest problem is that its under warranty but since custom rom i can't take it to service unless i have money to pay... which i dont
I have NEVER DROPPED it, it was never in water, and so on. Doesn't have a scratch at all.
It even has sound, and everything. Just freaking black screen ....
So what i am asking is if anyone here knows how to remove custom rom and custom recovery over pc,is it possible, without the screen? Any way to do it so i can get warranty back ? All i need is a freaking stock rom and stock recovery and a binary reset i guess. Just freaking would need screen to work for 5 mins eh....
If anyone has any ideas please post them, thanks..

I think you can boot to download mode or revovery. The LED notifi and backlight buttons won't turn on if you boot to download mode or recovery.
Just try to boot to...
1. download mode. Just press and hold for 2-3 seconds power + home + volume down
2. then wait 3 seconds. After that press volume up.
3. Connect your phone to pc, open odin and check if a device is connected.
4. If a device was found by odin - flash a ROM (stock or something else) and hope that this will fix the black screen problem.
Good luck!!
Hi, thanks for ur reply but... My phone turns on when i click home + volume down + power button. I hear sound, blue led notification and so on.......
But when turned on, when i connect to usb odin recognizes it, says connected, and when i try to install the rom i it takes really long and on the end i get fail..*attached the screenshot of fail) I guess because its not in download mode. Any other suggestions how i could get in download mode more?
More suggestions please?thanks
Anyone has any ideas ?
So what all i tried is
Remove battery, hold power button for 1-2 mins, let phone for few mins and turn it on. didn't work
I tried with adb,but usb debugging not on so cmd cant find my device
Only thing left i guess if someone has idea how to get in download mode in some other way or some program that doesnt reguire download mode but can flash rom and etc.
@Crazeh
Take it back to the nearest service center and act the dumb ("I don't know what is wrong with it")
I have done that many times
They are prob gonna call me and tell me to pay for fix
No one has any idea what else should i try ?
try link2sd app form play store. it has the option to boot to download mode. I think titanium backup has the feature also.
My screen is black so i can't do anything on it.....
try to disable ambient screen. report if problem persist
How should i disable ambient screen ? While i can't see anything on phone cause of black screen ?thanks for reply Rox
Anyone?

ok so i think your problem isn't due to any rom but hardware problem
power off your phone remove the back , look on the left you see a little trap , open it , now you see connector it is the one of the screen try to see if you can disconnect and reconnect it
power on your phone and see if it work :fingers-crossed:
Where is that little trap?
btw if i do this will i loose my warranty completely ?

If Odin recognizes it, it means it's in Download mode. The device has different interaction with the host over USB when it's not in Download mode.
I don't see the screenshot of the failure. It may be that something got broken in your hardware, so the flashing fails. There's a known issue with the S3 called "Sudden death syndrome", I don't know if it applies also to the S3 Neo, where some of the memory of the ROM fails suddenly. If that is the case (I'm not saying it is, but it might be), there's no fix other than replacing the hardware.
Odin doesnt go over setup connection. cant post screenshot bc im new to the site. btw im sure the phone is on but recognized in odin...

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$.

Phone vibrates but wont show screen?

So after i had sucessfuly rooted my galaxy, unlocked the bootloader and installed cm13 2-3 hrs later cm 13, starts to turn off the screen but stays working since i had it connected to pc and i was able to move files back and forth... now since i couldnt get it to stay working i decided to restore using twrp but after slidingto confirm the restore the phone immediately shuttled its self down, so i decided to flash stock rom which it did flash but with screen off while odin was doing its thing.... now when i turn it on i can hear sound but no image and for the screen to work i have to connected it to a power sourse first then turn it on but stays stuck on verizon screen loading!! so i flashed stock rom again but again same thing!! EDIT now afer it went past verizon screen it said set up wizard stopped working.... i have flashed stock rom like 5 times now..
Current status of phone: phone will turn on sometimes with visuals but most of the time you can listen to it booting with no visuals untill it reaches verizon and just hangs there, last time booted some kind of accecibility feature that telling me what the phone was doing at all times, just right after the verizon logo saying " set up wizard stopped working"
- i can access download mode and recovery mode sometimes with screen working and other times without it working so i might just be soft bricked maybe bootloader brick?
Flash stock firmware with Odin and immediately after flashing, wipe data/factory reset in recovery. Then reboot

This actually worked and booted the phone thanks man... however i dropped the phone and now when the screen do turns on but after couple of minets of usage like 3 minets the screen shuts off but the phone stays fully working, does this means that replacing the LCD will fix this? or maybe something inside is loose as a result of the drop?
Edit: actually after screen shuts down and i leave alone the phone shuts down completely and restarts when i attempt to push power or home buttons and after it restarts the screen is not visible anymore... so to get the screen to show again i have to remove the battery and wait couple of minets to put back on and sometimes this gets the screen to show but some times it doesn't... if i remove the battery and immediately put it back on this wont work i should mention

OnePlus 2 not responsive after turning off the screen

Hi All,
My OPO2 becomes not responsive at all after keeping the screen off for more than 1-2 seconds.
Turning on and off the screen fast works well.
It is not really powered off because:
1. I can call to it, but there is no ring and no option to answer.
2. In order to turn it back on, I must long press the power button.
If I keep the screen on the phone works just fine for long hours.
I've tried factory reset, and even switched the stock OS with CM - and the issue reoccurred.
Happening only when unplugged.
Any ideas what else I can try?
Appreciate very much the help.
Same happened with my other Android device it would go unresponsive after I lock the screen I think it is a hardware related may be your proximity sensor is faulty check with service center.

Full wipe and try reflashing stock oxygen os 3.0.2 it may solve ur problam
Solved!
Hi,
Actually I had the capacitive buttons and the home button not working at all either,
so in this case it came into my mind that they may cause this issue to happen.
I have simply disconnected them both from the motherboard and the problem solved!
Obviously, replacing them is an additional option.
Thank you everyone for the help
