I have a issue that has perpetually got worse as time goes on. My screen will just black out for no reason, usually only comes back with a battery pull. Occasionally it will turn back on if I press the sides which made believe it was the connector so I took the back off and disconnected the screen cable and reconnected it. Problem still continues. Tried safe mode in case it was an app, still happening. BTW when this happens my lights on my buttons still light up but as the screen is unresponsive I end up having to pull the battery and usually that works (sometimes takes more then once to do it) Other then that the phone works fine. This happens minimum 3 times a day. And lastly if the screen needs to be replaced, what's that run cost wise? Or can just a cable be replaced?

Basically I've been having charging issues for a while. Have to let it sit for a while before I turn it on and charging is extremely slow.
I accidentally let the battery drain, and plugged my nexus back in, and now I'm just getting screen flickering every few seconds?
What I've tried so far:
1. There's nothing I can do in terms of getting into the bootloader or anything similar ..the screen is unresponsive in my attempts to hold the power down + volume
2. I've opened my device, removed the battery, and plugged everything back in. Still nothing
Any suggestions?
Update:
I left the tablet in the charger for about 3 hours, came back, and the screen was still flickering at the same pace. Still unable to turn the device on.
Disable.. I think it's nvidia prism, it's broken.

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.
Tonight, my turbo 2 started acting up. I pulled it out to make a call, and the top 1/2 inch of my screen was flickering purple. That went away after about an hour, but then the whole screen went black and unresponsive. After trying to shut it off and reboot for a bit, it just randomly started working again. Full battery. Everything works, except the top 1/2 inch of display is completely black, every now and then, it will be green. If the phone sleeps, even for a second, it won't come back on, for about an hour, then it will randomly start working again. Never got wet, or dropped. Any body had an issue like this?
There's a known issue with a green line on the screen, I believe the speculation is a bad batch of screens got out, you're gonna have to exchange it for a new phone.
I am currently having this same issue. Going to VZ today to see about resolving it, as really hard to do anything when its doing that. Top 1/2 or more of the screen is flickering purple, then the screen will not let you turn up the brightness, all programing in the back works, just a LED issue. Restarted and same thing, let it charge Off all night, and back to normal after a few minutes using it. Very odd, not sure what is going on.
I have a similar issue, and I am trying to recover some data from mine. It seems booting into bootloader mode and using ADB yields nothing
I also cannot use MTP, as when I plug my phone in it's not in MTP mode for some reason, and i Can't see how to turn it on (screen is black). Digitizer still works. Does anyone have any suggestions? Can someone here maybe take a video of themselves plugging the phone in via USB and then selecting MTP on the phone? perhaps I can do it blindly...
Really don't want to give this phone back to vz until I get my data off of it.
About eight hours of pissing and moaning and I finally figured out:
Using the replacement phone, I just mimicked every movement on the one with the dead screen. I hit the "cast" button on the notifications panel and casted the screen to my chromecast, which in turn allowed me to set up MTP mode and/or anything else I wanted.
Cheers, hope this helps someone
So about an hour after I got my phone I went to turn it off and charge it a bit to full.
Upon coming back to turn it on the screen is completely black but has reaction to touch.
Tried rebooting and all button combos still off.
About an hour later full charged my guess I noticed the screen still black but has a glitchy blink around the top part edges of the screen.
I've not installed any apps just took a few pics ran a benchmark.
Anyone else have this issue ? Luckily Verizon is replacing it immediately.
Sounds like nothing more than some faulty hardware...tough luck

Have had the phone for a while now but for some reason recently the phone will randomly shut off. Some times it will immediately start booting back up but more often then not it will just stay black. holding the power button does not turn it back on and some times even holding the power down and the power button doesn't work I just have to wait. I'm not sure whats going on.
The problem is this most recent time it did this and the light was solid blue. after a while a green light started to flash slowly while the blue was still illuminated but the phone would not power on no matter what I tried. I took the back glass off and got to the battery plug and unplugged it (thinking that it was just a hard freeze) now i have no lights and I can't power it on. I don't even get a battery or any lights when I plug the power in.
Has anyone seen anything like this or could give me any other troubleshooting steps I could try to follow? I've put the wireless charger and retainer and screws back in but haven't resealed the back glass in case I have to go back in.
Seems to me like the MMC (memory management controller) chip is dead.
That's a motherboard swap isn't it?
So I opened the phone as disconnected what I think was the screen and some other plug on the bottom left of the mobo maybe the touch synthosizer? I let it sit for about 15 20 mins charging. I plugged all the connectors back in and it booted properly.
Why did that work?
Now that it's up I did a factory reset put apps on one at a time and using Snapchat causes the phone to shut off.
