I have been using Nexus 7 (2013) 9 months.
no physical damage occured, i had never dropped this device.
I rooted this device last week and it function well.
last night i charged my device the whole night (from 12:00 to 8:30) when battery is 30%
But this morning I am using Facebook app on this device and i ligt it on the table and make some chat with my friend fo 15 minutes
when i came back black Screen appear and i can't do anything with this device.
Although screen is black
1. if i connect it to computer i can see this device and can access all file and folder from it .
2. i can hear unlock sound when i swipe black screen. (may be touch sensor function well)
i had tried hard restart. remove back cover, unplugged and replugged battery.
but tablet is still black screen. and nothing appeared.
it also not appear google logo and backlight.
what should i do?
I was going to suggest holding down the power button for 30 seconds, to force it to turn off, but you said you pulled out the battery. How long did you leave it out? Try 5 minutes, then do not turn it on, but plug it into the charger and see if the display shows the charging indicator.
If there's still no display, a chip may have burned out, or there's a bad connection to the display. You could send it in for repair, but the problem is that if Asus sees that you opened the back, they may blame you and deny the warranty.
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.

Hi,
Really need some help with my LG G3 phone.
Bit of background
My phone network is O2, my kid was watching a you tube video and all he did was hit skip ad and my phone shut down. My phone at the time of shut had around 95% battery.
The phone does not switch on now, when I insert the charger no lights appear stating it charging nor does the screen come on. The phone has not been rooted or anything like that.
When I remove the battery and put the phone on charge the screen displays an image which states no battery is included but when I insert the battery back in the phone displays just goes dead again and nothing occurs
What I have done
I have bought a new battery and still no joy with that
I have held Volume Button down and Power button and no joy
When no battery is in and the above process is followed the screen flickers after around 13-15 seconds but then still shows that no battery is present
Last night the phone did show a little sign of life. I left it all day by itself and then just switched pressed the power button for 3 seconds or so and the LG boot up screen kicked in but then after 10 seconds it switched off. It has not replicated this again though.
Does anyone have any ideas of what i could try next?
Hi All,
I have an LG G3 and have had no problems for the last 21 months with it, however suddenly the phone screen will not power up. it appears the phone is getting power as when connected to the computer it is recognised as a USB device intermittently.
If I remove the battery and put it back in then power on it will begin to boot but then black screen.
the screen is working as when there is no battery but a usb cable plugged in the no battery icon appears clearly.
Ordered a brand new battery which has not fixed the issue.
I have tried to hard reset but the phone simply turns off after about 10 seconds.
any ideas?
Very strange problem. I have a LG G3 D855 for 1 and a half years now(rooted)
My phone was at a very low percentage, and I heared it go out. Happens to everybody, nothing strange so far.
I connected it to the charger and I turned it on, i heared the startup noise, but nothing happened. No pincode screen or unlock screen. Stuck at LG life is good screen. I actually was able to take a screenshot, i heared that sound when pressing power and volume down key. I know it is just right away from the main screen, but why is my screen freezing at startup logo? Tried to hard reset and clear all data, then I get a secure confirmation (verify) error. then my led starts to flash red and blue. Battery taking out and still no success.
How to fix this? Also screen is recognizing touch at the startup screen (when it fades away i click on it and it turns brighter)
EDIT: I blindly went into whatsapp and i am able to type and answer calls blindly wtf. Now I got a blue screen, everything is operational, the screen is blue now
Phone is functional, the screen is stuck on boot (life is good screen or blue screen)
How to fix?
Lol, the day after I hit my phone on the screen and restarted it and it worked again! I really dont know how it works again, but lmao! Also my secure boot sector is not working, that problem has nothing too do with this fixed one.
