[Q] Nexu 7 (2013) Black Screen no backlight - Nexus 7 (2013) Q&A

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.

Mi sw3 not work

Hello.
I have a problem with my sw3, on Saturday the screen was left locked and not to touch either the case or the button, so it was an hour before the screen went blank.
I was on charge overnight and encendia.ayer not try it with the computer but I just recognized a second and disappears, look in Device Manager.
I plug in the pc and I have to take down the power button for 10 seconds for the second appears to me.
I've also had pressed the button 15,30 and 60 seconds to see if it's something and nothing.
nor would I detect the companion PC.
nor would I detect mobile via Bluetooth.
It may be that this power but with the screen locked and not this downloaded?
the day that tennis is 40% of battery block.
someone else has happened?
greetings.
1st thing: Never charge over night. Charge it before sleeping, then turn it off.
2nd thing: Happened to me too, just after charging, powered off. It was super hot, the sun was shining on it, I booted it, and it just froze. Let it power off (No more battery) , then charge it again. It may solve your case

Phone not turning on.

Hi. So after a long wait I got my Zenfone 2 ZE551ML today. The first thing I did was turning it on and it turned on normally, then I proceeded to make the initial setup (logging into google account, etc) without any problems. Then after about 10 minutes of use the phone suddenly turned off with the battery being at around 35% and didn't want to turn on again. I read that old firmware (like the one that comes default with the phone) had battery display errors so I thought the phone had run out of battery, so I charged it for 8 full hours and I unplugged it now. To my surprise the phone is not turning on either. The only way I can make the screen show something is by connecting it to the charger, it vibrates and displays a white battery icon, eventually changing to fully green (fully charged battery, the green led indicator also appears) only to disappear like 3 seconds after. Can't turn the phone on while charged and can't even make the phone show the battery icon again (unless I unplug and plug again, repeating the cycle). So, what can I do to turn it on?
Thanks in advance.

I have a feeling that you did not hold the power button long enough. Disconnect the charger first, and wait for about 10 seconds. Then, hold the power button for at least 6 seconds. The phone should then vibrate and then you may release the power button. Other reasons why your phone may not seem to be turning on at all might be due to the back cover not being fully locked in, thus not making any contact with the power on the motherboard itself.
Do report back the results.

I did. Doesn't work. I also removed the back cover and pressed the power button with nails with no results either. Personally I think there's something to do with the power button as it doesn't even responds while charging (pressing it should display the battery icon) and the only time I could use the phone it didn't work to wake up the phone or setting it to sleep, only double tapping worked. What is strange is that it worked the first time I turned on the phone though.
Are you able to get into FastBoot mode? If so please try performing a hardware reset including wipe cache partition. Please see the following:

Lg G3 Phone not working / not responding

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?

HTC 10 Unresponsive & Can't Restart But Alive

I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.

Screen Doesn't Appear to Work

I was on a phone call with a friend when I noticed that the screen wouldn't turn on anymore. After the call was done, I popped out the battery to shut it down.
When I take out the battery and plug the phone via usb charger, the screen turns on and is blacked out. When the battery is in, and I 'turn on' the phone, there is a very slight vibration, and after some time the phone blinks that red LED light like when I have a gmail waiting--it is as though the phone really is on and active, but the screen isn't getting signal.
I'm guessing that there's a loose connection somewhere.
Any suggestions?
I disassembled and reassembled. Didn't work initially.
Left my phone alone for 5 minutes after it booted with no screen signal, and then I press the power button, and it turned on.
So weird. Seems like I'd better back up my stuff while I can.
