I just got my 16gb Nexus 7 from Staples and I plugged it in to charge as soon as I got home. I haven't even powered on the device and I can see that every few seconds while charging, the screen goes from dead black to slightly back-lit and back to dead black.
Does anyone else have this issue?

My nexus is on cleanrom 1.1 and somehow I've noticed that when I try to charge it, it usually turns itself off. After that the screen with charging icon appears but it doesn't charge at all. I have to turn it back on for it to start charging and then sometimes, it turns off again. Is it a hardware defect or a rom defect?
Hey guys, been using my Focus for about 2 years with no problems, last week it randomly shut off. I plugged it in to let it charge, I got the Samsung logo for about 4 seconds and then a black screen. Every now and then it would turn on and show a low battery screen for a few seconds, then shut off again.
Plugging it in and charging it did nothing, so I ordered a new battery
Swapped out batteries and nothing, same problem. Sometimes when I plug it in, I don't even get the Samsung logo. It's all very hit and miss. Not sure what to do here, seems like the phone is a goner but I'd figure I'd see if anyone here can help.
Cheers.
I was on my computer when i remembered i has something written in my tablet's notes that was important. I took it out of my bag and noticed it wouldn't turn on, it was out of battery (hadn't touched it for about a week). I just plugged it in the proper asus charger and put it down and went straight back on my computer.
I decide to check on it after 2 hours thinking it would be near or fully charged. I pick it up and noticed it was on a blank back lit screen. I unplugged it and then the screen turned straight off. Wondering if it didn't charge at all i re-plugged it in. There was no google logo (rooted), instead it turn on with a lit black screen and off and repeating a few times and then small thin artifact pixels run across the screen (red, blue and yellowy colours) and then stay at a black lit screen like when i first picked it up. I had just noticed a small buzzing sound while this was happening and still does so when stuck at the screen. I'm pretty sure it was buzzing when i had found it.
I redid what i had done (unplug, replug) and watch to see if it did the same thing. It did. I tried to power it off while it was at the black screen and it did, but then it would turn back on and etc. Same if i tried to enter boot loader or any key combinations.
I've tried disconnecting the battery and reconnecting and same effect (tried it without battery attached also)
I have a feeling it is dead now and i have no other ideas (checked many forums but got nothing).
Any help would be appreciated.

It's surely hardware failure, have take some humidity or something like that?
Try press power for 60 seconds, if you wont see any Google logo there's some hardware failure you need to RMA ( http://en.wikipedia.org/wiki/Return_merchandise_authorization )
found the fix
I found away to fix my nexus 7. You could be right how it might have a minor hardware fault, live in australia in the high hot tropics (high humidity). I decide just to plug it into my computer usb charger instead of the proper charger since it had a lower max amp output. Against my ear, a much fainter buzzing is still heard but this time, there was nothing. No power, no back lit black screen, just a very faint buzzing. Decided to let it sit just to see what happens. After an hour or so, i decided to press the power button and noticed there was a battery charging signal. To my delight, I'm sure it was in working order now so i powered it on and oh how relieved i was.
I determined that my device might have had a small hardware fault that made it draw to much power from the 2 amp original charger and thus why the tablet could not boot up properly (from battery depletion). Either that or my charger could be bugged to. But the thing is, since it charged to slow from the usb, i plugged in the proper charger and it worked fine. Just have to try not deplete my battery i guess.
Thanks.
My Nexus 7(2012) 16 gb appears dead. Was on CM11 with TWRP recovery.
Here's what happened :
I was using my N7, the screen froze for a second while scrolling on the browser.
After that a dead black line appeared permanently in the middle of the screen(horizontal).
I figured it might just be the case of dead pixels.
I continued using it like that only.
After a few weeks of usage, now the device won't power up at all.
When i connect to the wall charger, i just get a back light. No display. Nothing.
I tried booting into recovery, but nothing appears on the screen.
I kept it charging for few hours, but no luck.
It only flickers when connected to charger. Disconnecting the charger causes no activity what so ever on the device.
Nothing happens if i connect it to computer via usb.
Any solutions i can try?
Press & Hold the power button for at least 10 seconds while plugged into a power source. If no signs of life after completing the above step my first thought would be a faulty board..
Its just a black blank screen.

Well, I would hate to be the bearer of bad news but it appears your device had a critical failure and is now dead... Obvious answer right? HaHa
RIP Nexus :crying:
You can always try and leave it to charger for a day and see if you get some life to your nexus. I had similiar thing with my nexus, I was actually booting new ROM and then it did some flickering and got blacked out. After connecting to charger nothing happened, just random flickering. I was able to recover and get it back in bussiness when I woke up next morning (it had been charging over night). This was almost a year ago and atm I'm writing this with the same particular device. So give it a shot again, you might still get it back to work. Also you could try to boot the device to fastboot mode by pressing power+volume buttons at the same time for a while. Good luck, let me know if you were able to get it boot&work again!
You could also try popping the back off and make sure the ribbon cables for the display are seated properly. While your there check the battery cable.
Hi,
I've been using a Nexus 4 since 3.5 years and suddenly one day the phone started to misbehave. It started showing the charging sign without being connected to the charger and the next day it wasn't charging above 20%.
It isn't switching on now.
When I connect it with the charger, for a few seconds a very dim green led blinks and then goes off.
Sometimes the charging sign does show up but within a few minutes it goes off.
Once or twice I don't know how I reached the boot screen and came across the 'Android is optimizing' thing but the phone again switched off around optimizing app 150 of 173.
I purchased a new original battery from the LG service center but it also didn't help.
The reply I got from the service center was that they're unable to understand the issue with my phone.
Also,
I've noticed that the green led brightens up when I press the cable too hard but then automatically goes off or dims.
Please help me with this issue.
Thanks in advance.
