My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn't drop or hit by anything. i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life
GUI crashed. Press Power+Vol up+Home (for approx 20 sec).

I tried several times.. nothing happens... any other suggestion please
Power+voldown+home.
If this does not boot, you could try with usb dongle.
Or full run down to empty battery.
Next chance would require to open it.

It's not bricked so calm down. It just had a cyber stroke. It will be fine just let the power run out and recharge the battery so u can turn it on again. Same thing happened within days for getting mine.
yes... I am waiting for the battery to be completely dead. so far its on...taking calls and sms..I don't howmuch % of batter is left cause I can't see it.
I had the exact same problem once....and i had a hunch that the screen was fine, it turned out it was thankfully....but....im aware that on 100 percent battery in standby it can last a good week or so....i was too impatient...so i ran my fingers around the edge of the backing and slowly was able to pull out the back of tge case and unclip the battery...worked straight away when turned on.
But also what i discovered does reset the tablet forcefully is holding power, vol down and the center button at the same time....try it a few times for a minute each time...if successful you might get a message about being in download mode but then just do the same thing again but imidiatly release your fingers once you see the screen go off from download mode or it will just go bavk into it...good luck m8
Have you tried holding down the power button for awhile, like 30 seconds? This should shut your device off....Then take it from there.

Seriously on my tab right now i just held vol down, power and center button whilst on and after 25 seconds screen went black then gave the "are you sure you want to enter download mode." Then i tapped vol up......t805 as well.
Battery completely empty.. tab S turned off, i plugged in the charging cable (1 ) battery meter does not appear (2) Power+vol does not work for me.. if it does.. i can't see because of the dead screen...
i have 2 options now..
(1) send it back in warranty.. this will take a lot of time and they will only fix not replace.. i guess
(2) open it and fix the display.

Hello,
Did you finally got some result?
I have exactly the same problem with a Samsung Galaxy Tab S 10.5. The screen suddenly went black although the light leds (home, back) were on.
I tried different combinations of buttons, usb charging and nothing. The only difference is that now the light leds are off.
---------- Post added at 08:46 PM ---------- Previous post was at 08:32 PM ----------
I have achieved to boot up the device because I have heard the start up sound and some notifications. However, the display doesn't work at all: the screen is black and there is no response when touching it. In addition, the light leds of the buttons are off now even when I push the home button.
Volume keys are working (I hear the sound then touching them).
Hard reset is VOLUME DOWN(left side on a 10.5) + POWER. Hold until it restarts.

That doesn't work, as sarhn007 said the problem is that screen is dead:

But I can't figure how could this happen in a new (2 month) high-end product... I think that I will have to use the product warranty with the cost in time it involves.
This has happened to me twice during the last year. The last time was just ten minutes ago. I tried everything mentioned in this thread. VolUp+Home+Pwr for a looong time. Just PWR for a long time. I saw on my Wifi Router that the tablet was connected, but no screen. What helped me was to do a combination of everything mentioned here. What eventually got the screen on was 1. I turned of my router and 2. Home+VolDOWN+PWR for (what I believe was) 10-15 seconds. Then I got the choice to do a normal restart or a device reset. If you come this far, be sure to press VOL DN when asked. Otherwise your data will be lost. Obviously, I can't say if the router pwr off was necessary or not.
What's really weird is that my LG G3 went into a boot loop at about the same time (less than five minutes apart). They are not connected other than using the same router. I've had my LG G3 for exactly one year without ever experiencing a boot loop. The LG G3 is rooted, but my SM-T805 is not.

It's easy fix, most of the time due to loose LCD cable. If you can hear anything on the background but blank screen, 99% is loose cable.
Remove the back cover, disconnect and reconnect LCD cable, make sure it's fully inserted, then secure the connector with tapes. Test by plugin to charger, press the HOME button.
If you do correctly, the battery icon should show up on the screen. Then put back the cover, you're done.

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,
As I woke up this morning and booted my beloved G4 the screen went fully unresponsive. It runs boot normally apparently, but no touch is being registered after boot finishes at my normal unlock screen. No vibration even. No pattern swipe, no camera app, no emergency call. Battery went in and out several times, but it boots nicely again and I`m back where I was. No loop, it boots only once. Double-tap on screen functions perfectly tho, no prob there.
I tried a hard reset w back buttons but it captures a nice screenshot for me. (Funny story: when I pressed just the up and down volumes it boots normally as well.)
USB to PC doesn`t recognize cause unresponsive and locked. Fully stock, no mods, root or else...
I bought it last October on Amazon unlocked international version so it must`ve spend some time on a shelf probably.
Any ideas?
Galaxy A50, circle with lightning bolt (battery low icon) when trying to power on, with full load, is not connected to the load https: //youtu.be/h0lnht5kdew
with low load, is not connected to the load https: //youtu.be/kp7OQXETyXc
When the phone is shut down and i am trying to power on, This icon shows up first on long pressing the power buton. Then pressing the power button second time switches the phone on. Any idea? (Ps- showing this even when battery is charged. Basically on every boot)
I have already replaced the firmware It always appears,
Sorry My English
I have same thing with grey circle and lighting while powering on. Any ideas???
I have the exact same issue on my A50
I Have the exact same issue, did you solved it? Could this be a firmware bug or hardware issue? The phone has updated several times but the issue still persists
Thanks
You're Not Alone..
I Just Did A 14 Day Exchange With My Original Unit...
And It Literally Happened On The 14th Day...
It Got to the point where you needed to have it connected to a charger just to power it on...
That Should Get You Guys Going... :good:
But I now fear... this is a "Luck-Of-The-Draw" situation..
And may happen any time to any unit.. even though my New Replacement Unit seems just fine so far..
My Advice would be for everyone to shut your unit Off and On at least 50 times... to see if your device triggers this Horrific Issue..
Between this fear and the Bluetooth issue of Cutting In and Out... that also seems to persist on most units, I may do an upgrade to an S-Class Unit..
F.Y.I. My Unit is an Xfinity-Class A50u..
This is happening to several A50 users...
but there is no way to fix it :crying:

Shure it is. Return to Samsung service point.
im a samsung a50 user and the only ways i know to turn it on is. 1. turn on while charging 2. power on and volume down pressed together. i could say this malfunction started when i broke my fast chargin adapter and used another samsung non fast adapter.
samsung A50 problem with lighting bolt while turn it on
I have exactly the same problem while trying to turn it on. I complaines several times to the oficial service, they replaced it with a new one, as it was under quarantee, and from the first time I turned it off and on, the same thing happened. It takes 5-20 efforts before it turns on.
I complained again, to the Customer Service of Samsung this time, but they have done nothing so far.
Any ideas of solving it..?
I have a samsung A50.It worked fine for a year after I had purchased it.now my warranty period has been exceeded and it is showing the same issue as above.My fast charging adapter worked in good condition when I first encounter this issue.(when I pressed power button phone didn't turn on and there was the symbol of lighting bolt and the circle.)so I connected my phone to charger and pressed the power button.then phone switched on. But after that my phone didn't charge using the fast charging adapter.so I reset my phone too.every time I switch on my phone by pressing the power button same thing happens and phone isn't turning on.only way to turn on is connect to the charger(new fast charging adapter) and pressing the power button.if any one has a fix for this please reply....
