Hello, sorry if this has been answered, i did a search for black screen and didn't find the same thing.
Basically my nook hd+ is about 2 months out of warranty. When i try to power it on, i can see the screen light up but nothing is displayed (its all black and dims slightly). When i was messing with it trying to reset it, it started to read aloud the applications i touched on or button i pressed. So the touch screen is still working even though it's not displaying anything. I tried to hard reset it, by holding down the buttons and pressing the n twice, but that didn't seem to work either. Anyone got ideas?
Don't know what that is -> "holding down the buttons and pressing the n twice".
But if I had this problem I would...
Hold down the power button for >10 seconds as this completely turns off the device, then attempt to turn it back on.
And if that failed to work... let it sit and run out of battery, then plug it in to the wall usb adapter, let it charge for an hour, then try powering it on with the power button.
And if that failed to work, since its outta warranty, buy something that works.
But that's only what I would do
The Mrs dropped the tablet and the touch function of the screen stopped working. No amount of cold boots helped so I decided to pop it open to see if I could see anything loose.
I could see that the cable towards the top left (by the power and volume buttons) was loose from the motherboard so I put everything back together.
Now the screen shows nothing... I can see the light come on but nothing is displayed
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!
Hi! Hope all of you are well
My problem is that about the title, I had to change upper motherboard because dead Power and +/- Volume buttons. Between my brother and I did the job, we put all in the same way the old mobo was, the phone charges until charge LED goes green as normal, the new Power button works because when I press it the phone does the typical boot vibration, but screen dead, it doesn't show nothing, even after waiting a few minutes until it fully boots the OS the Home, Menu, Back and Search buttons doesn't vibrate after pressing them
Any help and suggestions will be well received and appreciated
Thanks in advance!

Tab s2 8.
Was using practically fully charged tablet one minute, went to use again and screen black.
Back and task switch buttons still light up when press power or home. Plus volume up/down makes the louder/quieter beeps.
Power and volume down gives me the quickest flash of the samsung and android boot logos and then screen black again. Makes the email received notifications you get when restarting the tablet.
Is basically on but just no screen. But screen still functional enough to briefly show boot logos.
Any thoughts?
Update. After about 30 mins of faffing, magically returns to life. Any thoughts on common issues that might have caused? Indicator of something about to go wrong for good?
Put down gently today and the right side of the screen displaying flickering dark/black stripes. Left side of screen perfectly fine. Touch still works over the whole display. Any ideas? Internal cable come loose? Or something more terminal? How easy to check/fix?
