How to return Nexus - Nexus 7 Q&A, Help & Troubleshooting

Ok, weird or what.
Bought my tablet, as new from Ebay, still has warranty etc.
Anyway.
Turned tjhe devices screen back on, had be using it fine for the past week or so, and suddenly the device was black with white lines down the center, like the lines on the digitizer.
I clearly have a screen defect, hasn't beem dropped. Fully charged, what tje hell is going on.
How do I return the device, more importantly, will I still be able to or should I go to sleep crying over what a waste of money it was?
Any help is appreciated.

Oh, well the device is working again, but cannot explain what happened. Any ideas?
It was a black screen but the centre have was showing vertical white lines, almost like the digitizer.

Managed to gt a pic of it, this is what has started happening. Doesn't happen constantly, but seems to change to this randomly.
Turning the device on, plugging to charge for 5minutes fixes.
Any ideas please?

White screen - is my Wizard dead.

my first for ages.
I recently purchased a wizard which looks to be virtually brand new.
now the other day I updated it the the o2 uk latest rom as it was running a really old rom.
and it has been running perfectly, i have not looked into running any other rom or performance upgrades etc.
now I was using the device in landscape and after closing the unit my screen went bright white and my pride and joy is now not usable.
I can still acept calls, the touch screen still works but the screen is pure white.
Ive contact a few places and they all say the screen has died and needs replacing
Does this sound right.
its a £80 fix if this is right. im so gutted.
any advice is great before i pack it up and send it off.
anyone please....
Can you put it into bootloader mode? If not i would say you have a loose connection on the screen to the mainboard i had the same problem with my old phone the screen disconnected for the main board so no display! If you cant get it replaced take it apart and carefully check the connections if still doesnt work i would try another screen or buy one.
even when i reset it, it stays whits so cant see anyhting on screen,
ive had someone take it apart and re-seat the cables and still just a white screen
so im off to purchase another one in hope this is all thats gone
as your phone is booting up press and hold the camera button, is the screen still white?
cant tell now. ive sent if off for repair.
Im gutted.

I had a similar issue, the keyboard sliding in and out must have worn out the switch that detects when it is open/closed. I had had my wizard a year and the screen started flickering, i dealt with it for a while, then the scree was stuck blank white unless if i pressed on the area of the phone that had the contact.
I had to send it back and got a refurb.
sounds like thats what happened to you too. Hopefully when you get it back it will be good as new
ive sent mine for a screen replacement tho not a repair.
now im worrying that its gonna come back in the same state.
Gulp
got my wizard back after having the screen replaced.
2 days later when ever i touch the bottom of the screen with pen, finger or even breath on it.
the screen goes off and the phone locks up and dies.
I have to take battery out and restart it and it then works great till i touch the bottom again.
Sound like a dodgy screen or something else.
Seems like a flexi strip(The one conecying the display to the mother board) sometimes if the strip develops a tear or is not properly connected this issue usually happens.
the shop doing the repair have said there is the following issues
1- padding issue on the screen (either too much or not enough)
2- Problems with the main board. (something on there is failling, hardware wise)
How the hell could this be happening on a device that was working perfectly
apart from the screen had died.
have they done more damage attempting the repair... I think so .!
I had the white screen 6 months ago. Luckily still under warranty period so got it repaired. It was the flexo-cable. since the fix no problem so far despites using the phone (also in landscape mode) daily.
when i got it back after the screen was replaced my xda worked great but as stated as soon as some preasure was applied to the bottom of the screen it would just die there and then.
I would have to take the battery out and then it would power on as normal
but again if i put presure on the bottom of the screen.. bang DEAD !
so sent it back to them and they told me what I stated above !
now waiting 2wks to hear what they are gonna do about it
not a happy bunny
still nothing back from the company thats doing the repair.
i dont know why they do this.
Im now thinking of getting my Xda back, selling it either on here or ebay and purchasing a new one.
Should i quit now or wait out for the miracle that they fix it completly.
Anyone in the uk reconmend a good repair company please im pulling my hair out.

Touchscreen Non Functional

For the past few weeks the touchscreen on my HD2 has been sporadically going haywire. It almost always occured after a hardware button was pressed or if the phone was put into standby. The touchscreen would stop registering any presses as if the digitizer had gone belly up. To get it to start working again, You either had to restart the phone or spend a few moments fiddling with the hardware buttons and tapping the screen.
A few hours ago I took the phone apart to see if I could discover the problem and now it does not work at all.
I have noticed that ever since this problem started sometimes the LCD would not display the correct colors. Almost as if it had Yellow and Blue but no Red. Oddly flexing the phone immediately fixed this problem.
What do you guys think the chances are that it is just the LCD/digitizer that is shot? I would like some reassurance before spending $100 on this part.

[Q] Black screen of death, then too bright with lines, now normal??

Hello,
I got the Galaxy S4 yesterday morning. Today around 9pm the screen was completely black. I could hear sounds and the buttons would light up but nothing worked. I pulled the battery and sim card as suggested via google search and still nothing. I got home and the screen came back on but it was really super bright with horizontal lines that were slightly shifted in one spot on top of each other. I plugged my usb from the charger into it a few times and eventually got a battery charging logo to come up. Had to do that a few more times before I got the screen back up. Now the screen appears normal but I'm scared that something happened to it. Either the screen is going to die soon or maybe it somehow over heated and that is why the screen was acting wierd. I just hope that since it seems normal now that I can get it replaced in store even though I can't duplicate the symptoms.
I'm curious as to what your take is on what's wrong with my phone? It had at least 75% charge before it started acting crazy. I don't want to keep it thinking it's fine and then after 15 days it goes out again and I'm stuck waiting for a repair to be shipped back to me.
Thanks
I just did a live chat with a Samsung Tech guy. He says it's because I installed an app or had a sd card inserted. He told me to uninstall Facebook and any ebook reading Apps and see if that fixes the problem. Do they think people fall for this? So incredible stupid if that's how they train their techs.
I was able to replicate the symptoms again. I bought the s view cover and when installing it had to press a little hard on the edges to snap into place. The screen went black again and did the same thing. Plugging to power then restarting fixed it. I found out that when I press the top right corner around where the time is, the screen flickers black and looks like I wants to cut out. Is there a sensor or digitizer located at that spot. If it's an issue when putting on a case, I see this is going to not bode well for the life of this phone. I went back to the dealer today and she gave me the number and location of a local samsung repair center. I'll have to give them a call tomorrow I suppose. Just be careful of any pressure being applied to the screen, even though mine has been acting up on it's own.
Just checked it now and it went totally black again and is not coming on. I've only had it a few days so not even enough time to load much stuff on it or customize it. I'm with Wind Mobile in Canada. It's getting boxed up and taken to the store asap tomorrow.

[Unsolved] Distorted greenish screen, black except for split second on boot

Last night I was busy using my S4 with it plugged into my PC.
It was resting on a flat hard surface. Nothing abnormal.
I was looking at the screen, not touching the phone and it suddenly turned a greenish tint colour with noisy coloured artifacts on the screen. I could still use the phone, but it looked odd. Everything was still visible at this point, just tinted green and with the artifacts.
I decided to power off the phone, and then power it on again to see what would happen.
Afterwards, the screen failed to turn on... somewhat. It's been doing the following behavior since:
When turning on, screen on black, following by a quick split second flash of the 'Galaxy S4' logo. Then black again. When charging the phone, I can see the battery 'loading' symbol flash too, or when going to download mode, I can see the 'warning' flash. When holding down the power button to force the phone to reboot, I can see the screen flicker too. It appears that I can see some flash when the screen first powers on... but it can't stay powered on(?)
The first time this happened, I could see a 1 pixel line on the top representing the colours of my boot animation, when booting but that only happened a few times. Now it does not.
I have opened the device, and checked the screen cable. Detached it, inspected it for dirt or dust. Gave the connectors a gentle blow with a hair dryer to remove any dust and re-attached to no avail.
I can still access the device via ADB and see it's screen via Android Screen Monitor.
The digitiser is working, as I can touch the phone and control it... it appears to be a problem with the GPU(?) or the LCD?
Can anyone make any recommendations? I really hope I don't have to spend lots of money on fixing this.
Thanks, all!
Shameless self bump. Merry Christmas! Santa threw a nice BRICK of coal (or phone) for me
I don't like to bump, but I am going to have to... sorry
I'm abroad, and Samsung said they can't fix it under warranty while abroad? I'll have to send it back home. Really? Bleh!
Has anyone else had this issue before? Is the problem just the LCD, or could it be something else?
One more bump... Anyone have any idea?

Are you also having the same issue?
If I get my Samsung looked at by a Samsung repair center overseas (outside my country of warranty) will that void my warranty?
Still haven't got an answer for my issue... so.... bump!

Black Screen But Phone Is Still Working??

Hey guys
Just bought my moto x play. And on the same day it screwed on me. So after i got the phone i updated to Marshmallow, And left it in my room to charge. On my way back I realized my phone was not turning on. I turned it off and turned it back on but nothing happened. I only felt the vibration of the phone and seeing the screen light up black pixels (no idea what the proper term is)?
I can still use the camera with the twist gesture and i can still hear the phone taking photos when i click the volume rocker. But the screen is black and i cannot ue touchscreen to take phtos. I also noticed that the LCD lights up black again if i lift my phone up. Just like moto display would do with notifications. I also hear notifications on my phone but nothing else. I have serached for a fix but nothing anyone else have this porblem?

Most likely it's a hardware issue.Are you able boot into bootloader mode with screen working?
boot into recovery and factory wipe it.

Most probably hardware issue. Get it checked in care center .

I faced similar issue with my previous droid maxx, phone was on but only the screen's backlight came up. It happened all of the sudden when I was watching youtube. I thought the LCD ribbon connection was loose so I disassembled the whole phone and put it back on but no success. I ended up leaving it on the desk and one day the screen woke up on its own. The battery was at 1%, not sure if that triggered anything that fixed the problem. Maybe you could leave the phone until it drains out the battery and see if it could work for you.
Another way is to get into fastboot or recovery and do a factory reset
Maybe the flex cable is loose or disconnected
Assuming you haven't unlocked the bootloader,ask for replacement.

Yea I am. I have to wait until Monday for a reply
Hi Danny_Cai. I'm currently experiencing the same issue with my Moto Z play smartphone. So I wanted to ask, did you just replaced the phone in the store? And what was an actual cause of this problem?
Possible solution Motorola X-Play Back light Problem
Hi Danny,
I had a similar problem with my phone. Not under warranty so took the back cover off using a T3 star bit.
Radio Shack probably has it also.

At the bottom of my phone, there are two spring contacts. One was sitting loose and must have been causing some kind of problem. It fell out, and I did not reattach it. Haven't had a problem since.

It may be something as small as that. Not sure what it was for but haven't noticed any difference in the phone.
Hope you find your solution.
