I have a SM T520, 10.1 Tab Pro. I started having an issue with screen waking up.. When I tried to wake the screen up, buttons lit up. but screen stays dark, no matter what I do, I reset to default settings, I installed Cyanogenmod 12.1, whatever I do same result. Somebody says it is hardware failure. but when I reboot the screen is visible, it stays visible until OS darkens it, once darkened, the only way it comes alive is if tablet is rebooted.
Please help

So I bought my wife a new Tab Pro 10.1 model. It started doing this immediately out of the box. Screen works fine for a while. After you lock the device and the screen shuts off, it won't come back on. When you unlock the device everything works, except the screen stays black. Digitizer works, you can swipe to unlock, hear unlock sounds, and even the backlight keys work. Screen just stays off. If you hold power and reboot, the samsung logo shows up and all is good again, until you lock the device. I performed a factory reset, and even played with all settings I could think of. I don't want to flash a custom ROM to see if that's it, as I might need to send it in. Any ideas?

Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:
Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.
If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

My wife's phone looked completely dead this morning, so I pulled the battery and then rebooted. The led did its usual start up pulse but the screen remained black.
Double tapping to wake, then tapping the centre of the screen where login field is, then tapping where the keyboard is, results in haptic feedback, but the screen never turns on from black.
Tried holding down + power to boot into recovery, but no idea if it works. No response from the screen.
Anything I can try? :crying:

Its the faulty motherboard chipset issue, same as me.
Take the phone apart and place a piece of plastic or something on top of the display ribbon connector underneath the battery. That solved this problem for me.
Seems to occur because the board in the g3 has too much space to flex etc in general usage.

Hi folks!
I've got a very weird issue with my P-600!
Yesterday, I noticed a dark area in the left corner on the bottom of the screen.
At first, I thought a LED line was dead on the backlight panel. No surprises, it's a 10 years old device...
To confirm that, I rebooted the device expecting to get the same issue (dark corner anyway, anytime) but it became even more "bizarre": after getting into system again, the dark spot was gone but the device was unable to revive the screen after going into sleep mode.
No matter if the screen was put into sleep by inactivity time-out or by pressing the power button, when the screen became black, it stayed black.
But with apps still running in background: for exemple Spotify was still playing music.
The only way to get the screen on back again, was to force a reboot by keeping the power button pressed down.
After reading many posts here and on other sites, I found some talking about the "Android Black Screen Of Death" and some tutorials on how to fix it on Samsung devices. So I opened my Tab, unlocked all flat cables, waited 10 minutes or so and then reconnected everything.
Well, it did it but only partially: now I'm a in quite "mixed" and unexplainable situation.
The screen works again, I can put my Tab to sleep and get it on again just pushing the power buton.
BUT...
The dark area in the left corner comes back again, only after sleep mode!
If I reboot the device, the screen is perfectly enlighted in all its surface, but it will get again that dark spot in the corner after screen sleep. What the heck... ?
So it's not clear for me how to definitely fix it.
Should I replace the entire screen? The flat cables? The battery?
Any help to understand what's going on will be greatly appreciated!
