Black screen problem - Galaxy S3 Neo Q&A, Help & Troubleshooting

Hello, I have a problem with my S3 Neo. I haven't used it in a while and when I boot it up, it just shows a black screen, but I've discovered that you can see something on the screen when you're in total darkness, it lights up just a bit and shows a barely readable b&w image. All of the functions work fine, I've even managed to access the camera and take some shots with it. I have tried the method where you pull out the battery, hold the power button for 2 minutes and then put the battery back in after 10 mins, and it didn't work? My warranty has expired so should I look for a new screen or is it a problem with the graphics module of the phone?

Have you tried to adjust the brightness?
May be brightness is too low.
Otherwise it can be a hardware problem.

Of course I've tried that, but it just makes it a bit brighter, it's unreadable anyway. I've also tried flashing it with the stock rom and it didn't help. Do you think it's a screen problem or something on the mainboard?

Hmmm. I think it's a very little problem. May be the strip is damaged. But may be screen is not good anymore.
You have to take it to a repairing shop or to a Samsung franchise.
If you don't have warranty then they will charge you if they have permission to do so.

Display stays black after turning on and slowly fades to gray?

Hi
I noticed this two times now and sadly I did not make a photo of it. I will try to describe it:
The phone is in standby, I press the power button and the display stays black. Over 10 seconds, the black slowly faded to a sort of gray blur. It somehow looked like a can of white wall paint was spilled over the black display. Another buttonpress turned it off again and then it worked normal again. So the phone was still working in the background, not crashed. This also happened one time while I booted the phone, right at the google logo.
What is this?? Is it a defect, or just software bug??
Thanks!

Flash the stock Nexus 4 image, and if it still happens, get an RMA
I can do that, although I am still on stock and unrooted. Only applied ota 4.2.1 update. But I will give it a try!
edit: found two people on german forum who also witnessed this! so more possibly a software problem?
edit2: Got RMA

PLEASE Help!!!! NookColor Screen Is Green

I gave a NookColor to my oldest son 1 year ago, which was rooted & had CyanogenMod7 on it. The other day he said he was booting it & he pushed some buttons while it booted & when he did the screen turned green. It has never been dropped & he has never had a problem with it before this. You can see the icons, fonts & it still functions properly in all other respects...the screen is just green. The screen is also green during the CyanogenMod startup screen, then it goes black, then is green again during the CyanogenMod boot animation. I can tell that the screen is working normal, as it is lit up & black when it is switching between the boot screens.
I have spent many hours searching the net & cannot find this problem ever happening before. How can I change the background back to normal? Is this a hardware or firmware problem??? I have taken it apart & unplugged & reseated the video connector, just to be sure that that wasn't the issue & I've tried putting different Roms on it, including the new CyanogenMod10 for NookColor & it still has a green screen. I even restored it back to Stock & the screen looks almost normal, but when I played the Introduction video, the video doesn't look like the colors are right or something.
Does anyone know how to fix this or if it is even fixable?
Someone...PLEASE help!
Thanks!
Similar Problem here, except half of screen is green.

I have a similar problem, except only half of my screen is green. The half that is green remains in the same place, regardless of orientation, so I am guessing this is a hardware problem.

My experience is similar, except obviously I have half a screen of odd looking video and half normal. I also tried reverting to the stock rom, but with no success. Fortunately when reading books, i.e. just black text on a white background, the effect is not very noticeable, so the NC is currently back to being an ebook reader.
Still I'd love to know how to fix it. I see powerbookmedic (I have no connection to, or experience of, them) sells used parts for the NC, but is this a display problem, which seems likely, or a logic board problem? Buying both would be more than the whole thing is worth.

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$.

S5 GM900V Screen Flickering

I've read a lot about the screen flickering issue, suggestions range from changing options in developer options, removing your SD, squeezing certain parts of the phone, slapping it, replacing the screen etc. I was rooted on lollipop using this method: http://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370 and after the root the screen returned to normal for about 20 minutes. Over about a month or so after this the problem got worse, I'd have to press the power button 20 or more times to get the screen to come one and as of 3 days ago I haven't been able to use the phone at all. Today I was messing with it and found that if I reboot the phone holding the power and volume down buttons, the screen flickers and I see the yellow triangle with an exclamation point briefly, and flickers out again until the samsung boot screen, every time I do this, the phone stays on. I have USB stayawake on and if plugged in the phone will stay awake for hours until I push the power button to turn off screen, and then repeat the reboot process. Just in case there was a software issue I upgraded to the latest update by using odin, I'm now on 6.0.1 and the phone was working perfectly for an hour before it returned again. If the issue is the flex/ribbon cable that connects the screen or other hardware issue, I don't see how rebooting would help, but if its a software issue, I don't understand why its only after I turn off the screen. Regardless, even when the phone was working it would still flicker on the lowest brightness, but at least the power button would work. Anyone have any ideas?
I've been in this type of your situation believe me all those solutions you mentioned above non of them really work, infact i nearly got my phone twisted because of one stupid yellow flickers. As of now the only perfectly working solution according to my extensive research is first of all never put it in auto brightness, you can reduce the brightness to a minimum, this happens on many samsung devices like s4,note 3 and even some s6 due to the amoled screens you'll notice when you reduce your brightness to the lowest it start immediately. I only got one report on this same issue damaging a s5 but it rear so dont be scared of loosing your phone. I'll upload a sreenshot of my minimum brightness to give an ldea.

The not using auto brightness does stop the screen from flickering so if I have to turn it down, I turn it down to just below where it starts happening but I still have the issue of the screen not coming on with the power button consistently, it flashes on for a second then back off, not nearly long enough for me to unlock the phone, except for when I restart it using power+vol down
EDIT: I see now this probably should've gone in the help and troubleshooting sub-forum, if any mod sees this, please move it for me.
It worked perfectly for me except your is getting worse by the week. Never mind i just got a new way may be it'll work on your phone, move your brightness tray to the highest or at the middle, keep using it as normal for every day use for at least a week. It worked for my indian friend as he told me. Keep in touch.

The first day it didn't seem to make a difference but I didn't check on it a lot, after that I've checked a few times and it does seem to make a difference it comes on much more frequently now, almost every time, but what could be the cause of the issue then? When I thought it was the ribbon cable connecting the screen I wasn't opposed to replacing it if I have to, but now I'm not sure how to go about fixing this or if I even can other than just leaving brightness up
Just to update, keeping it on max brightness did a lot to solve the issues, but it was still under warranty through Samsung so I sent it in, its on its way back, but according to the report they replaced the LCD

TMobile S8 works fine, except the screen won't turn on

My brothers TMobile S8 screen randomly stopped working. It has no signs of damage anywhere as well. Weirdly, I managed to get the screen to go on one time by pressing some button combos to try to follow a guide to get it into recovery to factory reset it. Upon the phone booting, the battery had 3% and when I went to show him, it was dead. Now after letting it charge, the screen does not work once again and I can't seem to get it to come on in the same way it did before, the bright blue recovery screen.
Is there any software I can use to just attach the phone to it and factory reset it? I mean, I've seen bad phone screens before that have still had images show up on them, even if heavily damaged physically or it no longer responding to touch and showing dim lights. But this one simply doesn't turn on, except the one random time it did, and it was perfectly fine, showed no sign of damage. Any thoughts would be greatly helpful
Is the battery known to be good?
If not replace it. The system will not boot if there's not enough current. It takes a fair amount of power to boot up. A charger can't provide enough to do so...
It boots up fine, I can hear the initial TMobile boot audio as well as the notification sound the phone makes when it gets to the lock screen. I also had it stop charging @80% not too long after buying the phone on release, with some custom ROM I installed. Ofc its a possibility its battery related, since I can't see anything on it, but it was taken care than the average person I am sure
With a custom rom all bets are off. Makes troubleshooting much harder. Possible rootkit.
Firmware and malware aside if it's booting but no display, possible loose ribbon connector, failed display or mobo. That's assuming the battery is good...
Well I did disable/uninstall Superuser from the phone, and I used it for a couple years before giving it to my brother to use. That is a good point about the cable, I will search for images, maybe I can squeeze a few spots to just see what happens

Sometimes just reseting a connector is all it takes. Those are low voltage lines and a perfect contact is needed.
If the battery is more then 2-3 yo it's probably at the end of its usable service life.
Thanks for the input, I will open it up if nothing else works and I will report back if it helps
