[Q] s3 screen is blank, but is turned on - Galaxy S III Mini Q&A, Help & Troubleshooting

My s3 boots and volume is working, but the screen cuts on and off, mainly is blank, but if I press the power key, then the home button, it comes on for about two seconds, then goes blank again. The car app is on, and I can't turn it off because the screen wont stay on long enough for me to turn it off. Is this the problem or is it something deeper like a bad rooting attempt or hardware problem?

[Q] Boot Phone w/Broken Power Button w/o USB

I was wondering if there is a way to boot up the phone WITHOUT plugging into the usb i have tried taking the battery in and out and it doesn't work.
My phone sometimes shuts off randomly and my power button is broken so i can't just use the power button, this happens to me when i am away from home without my usb i usually just leave it alone and wait for it to turn its self back on but i'm afraid if it doesn't turn it self back on and really dont want to wait until i get home.
(I use Wake All to turn the screen on when it is already powered up and Screen off and lock to turn the screen of, i also have quickboot to turn the phone off.)
The best solution is: go to Motorola customer service and have the power button replaced.
Have a good day!

[Q] Couldn't turn on the screen

Sometimes, the screen couldn't be turned on even if I press the power button, it seemed to be dead, but if I long press the power button, the screen turned on, and the menu of restart and power displayed, I selected to restart the gear, and then all will be OK. It had happened 3 times, I wonder if it is a software bug or hardware problem.

HTC One Bricked - Turns on, but can't access fastboot or recovery

So my friend sold me his busted HTC One, telling me it wasn't turning on. I took it upon myself to get it fixed up.
It seemed completely dead, but after plugging it in to charge, and holding power + volume up + volume down, I got it to turn on to the HTC screen when charging, then turn off. I can access the bootloader screen by holding power + volume down, but the bootloader screen goes crazy.
The first option will keep selecting itself, then going back and loops like that. If I try scroll down, it instantly selects the thing I scroll to, which is either reboot or power off.
If I select recovery on the main screen, it boots to the HTC logo and turns off.
Not too bummed, as I only payed $35 AUD, but really would like to try get it fixed up.
Thanks!

Sounds like maybe the power button is stuck on. Hence the reason it is auto selecting everything. Also it would cause the device to force reboot.
When it boots to the HTC logo, are the Capacitive back and home buttons flashing at all?

Ahhh I thought that may be the case! Should be a fairly easy repair then. The back and home buttons do not flash at all.

Black Screen, won't do anything.

Hello,
I have a rooted and TWRP installed but otherwise stock 5.something T710 that I had worked on months ago. It's been great and my daughter had been using it to watch videos a couple days ago. I took the tablet from her at the end of our road trip and noticed it had about 63% battery left. I left it in the truck while we went to the movies(about 40 degrees f outsides) and then drove home without ever touching it until we got home. I went to use it when we got home and it would not turn on. I plugged it in to let it charge thinking it died for some reason, using the stock charger, though battery icon never appeared. The next morning I went to check it and it still would not turn on.
When I press the power button or plug in or unplug the charger the Recent and Back soft key lights will turn on for a second, then turn back off again.
I've tried:
Holding the power button down alone for over 3 minutes.
Held the power and volume up button for over a minute
Power and volume down for over a minute.
Home, volume down and power for over a minute
Home, volume up and power for over a minute.
I can connect it to my computer and it recognizes that my Tab S2 is connected but no files show as the default for the device was just charging mode and not the file modes.
Odin3 v3.10.7 recognizes it as connected. But fails to send the TWRP file again.
Any help?
Since the soft keys light up and the computer recognizes the device, it sounds like maybe the tab is still working but with no display? By any chance did you have adb working? I f so you could try rebooting, or booting into recovery to see if you see anything on the screen. It's possible that when you held the button combos, that it did boot into download and recovery but you couldn't see anything? In which case it could be a hardware problem. Hopefully it will fix itself! Sorry I can't be of more help..
Well adb shows the device as unauthorized. Reboot command says the same thing.
The home key is unresponsive to my finger print unlocks and no sound plays when I try to adjust the volume, like the ding sound it makes to hear if this is the volume level I want. There are never any of the capacitive touch vibrations or whatever its called to feel when you press a button on the screen.
I was wondering if it had something to do with hardware it's just strange that it would stop working from just being in my truck. From my knowledge it was never dropped or bumped heavily or anything, at least recently.
I guess it is possible something just burned up inside, that would be inconvenient, I've got to look up if its still in warranty. I love the size and performance of this thing.
Thanks for replying, hopefully more to come.
Still can't get it to work, same issues as above. I let the battery fully die which took about 2+weeks from the initial post. Which is to say that eventually the back and recent buttons stopped lighting up. I recharged it and after holding the power button for a few seconds the same condition repeated itself. If I touch the power button or home button the back and recent button back lights turn on for a moment and turn off again. There is no other indication of life. I would assume if it was just a dead screen then I should feel it try to turn on.
If I had to replace parts which ones should I look at first? Probably just the main board?
Buy a new one. Send yours in as defect. Done.

I see that is an old thread, but I having the same issue to a certain degree. The screen goes dark, but I can see the back light. If I play around enough times, (pressing the back and process button, before pressing the sensor button... Sometime, pressing the volume buttons and back button before pressing the sensor button), everything goes back to normal. Of course, it some random time, even when I am reading a web page or some other activity, it will go back to black.
So has anyone figured out what this issue actually might be? I thought maybe it was an issue with the ROM I was using, so I just moved over to LineageOS 16, but the problem still continues!

Power button doesnt wake up the phone.

Hi,
My note 8's screen got damaged a month ago, but
from past two days the power button seems to be
unresponsive.
I have to press it atleast 10-15 times for my screen
to wake up.
Even if the screen doesnt turn on by a single click,
the usual touchscreen functions still work.
Ex: I can still open the particular app by clicking the screen
on the specific area.
Kindly help.

There's nothing any of us can do to help you when it's a hardware issue like this. You need to open the back of the phone using a heat gun to loosen the glue and then take the power button out and replace it with a new one.. There's nothing else that can be done and I would suggest that you not shut the phone down or let the battery die out because then you may not be able to turn it back on until you get the power button taken care of!

Hi MrMike2182,
Thanks but let me elaborate the issue.
The power button seems to be working fine because it takes approximately 10 to 15 clicks to turn on the screen (sometimes 1 or 2 click)
Let's say that I click the power button and the screen doesn't turn on, the screen functions work fine despite showing black screen.
Ex:
1. If I click on screen location where samsung music is placed and open it, and if I and click on the location of the play button, it plays the music just fine.
2. If I click on the restart button when the screen is black (not turned on), the phone does restart. The Samsung logo lits up just fine. (Mensing to say, the bootup process is not affected)
Also, note that if I successfully manage to turn on the screen after clicking the power button 10-15 times and if I put it to sleep again. I can easily turn on if I click the power button immediately (within the span of 2 seconds).
The problem persists only if the phone is kept I'd for 5 to 10 minutes.

Ok based on what you said now I don't believe there's anything wrong with your power button and when you press it and the screen doesn't turn on, in reality it actually is on and it's possibly damaged which is why you can still use the screen functions with the black screen. Whatever type of damage you say happened to it could be causing the backlight to not work but the screens touch function is fine.. Try rebooting into recovery mode and select to clear the phone's cache only and see if it helped anything.. If it doesn't help anything it's pretty much a screen hardware problem and you'll still have to get into the phone's internals..

Thanks,
Unfortunately, even factory resetting the phone didn't work out.
Anyway, I will take for service.
Hopefully it might resolve the issue

Since the factory reset didn't work, then unfortunately it really is a hardware issue.. I think you need a new screen..
I have the official led cover case, just opening the case will turn the screen on... Just a temp fix until you can get it repaired maybe.
