Strange problem

Ok so last night my battery died, so I plugged it in over night and in the morning my alarm goes of, I try to open up my screen to stop it but my screen just stays black!
Everything else worked, the 4 buttons responded, the volume rocker responded, etc but my screen just stays black! no matter how many times I press the unlock button(which does respond because my 4 buttons lit up when pressing,
Anyone else here that had a similar problem?
I never really overclocked or not recently
I have nightly Cyanogenmod 7 build

Screen stay black even with repeated pushes of the power button, or opening the keyboard? Try pulling the battery and rebooting.
Did you charge overnight on USB, or the wall charger. Try charging on the wall charger overnight, if you haven't already.

Thanks for your reply,
Yes even when opening the keyboard or pushing the power button numerous times, and I charged the phone with a wallcharger overnight. The phone is on actually it's the screen that just isn't working, I can push the 4 buttons(also lit up) and it vibrates, the volume rocker gives me the preview sound level thingie. Sometimes It even vibrates when I touch the screen.
It's really strange because I didn't drop him or anything.
EDIT:
Ok so suddenly, i unlock him after the 100000st reboot, and i got this, and the lines keep changing very fast... hard to explain... as there is some interference
And this happens when I press the powerbutton, then do my normal unlock gesture. If that might help for anything

No one that has any clue?

Looking like a hardware problem to me...

What's his name?

Something could have happened to the flex cable that is where the hinge is. I'd take it to a local store to get it repaired under warranty.

Help!! Nexus 10 don´t charge, don´t boot

I´m on Paranoid Android, last version. I was whaching a movie with less than 4% battery, and It powered off. Problem is that It doesn´t boot and It doesn´t charge either.
Please please Help!!!
Sorry for my english

Hopefully your up by now after letting the device charge for a while. If not I'll throw this fix out in case it's a software problem. I have no idea, but: The Nexus 7 has a similar situation of not accepting charge after the battery runs dead. Maybe the same fix will work? With the charger plugged in, hold your power/vol button combo to boot into bootloader/recovery. From there select power off. Then the tablet "should" accept charge. It's the first idea I thought of, but I thought that was an Asus problem.

The problem is that you can´t boot into bootloader/recovery. Tablet doesn´t respond. When charger plugged in, It shows icon of battery when pressing power button but it dissappears in a second....

Hold power button 15-20 seconds until it vibrates & release. If no boot then, unplug and try it. I had this problem once also. Mine finally booted when unplugged for some reason (after being on a wall charger for a couple hours). Someone told me during my ordeal to first plug into a computer for the 1st hour, then go to the wall charger. I think holding until vibrate was the key for me, or so it seemed.

It seems to be charger´s fault. I can confirm it in one hour...
Edit: It was the charger...

Stupid stupid mistake!

I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:

you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken display” units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.

I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.

Not charging and screen wont boot up

Okay...Im trying to rescue my sister's data on her Note 3. We've replaced the phone but some important stuff remains on this one. Ive been messing with it for quite some time...replaced the charger port, power button and vibrator flex cable. No luck...except Ive noticed a couple of times after it has sat for a couple days if i plug it in it will display the battery with the charging volt and shortly after the red charging light will cime on. However, as soon as I touch the power button again (to try to boot it) the charging light gies out and im back to square one. Any ideas? Really need to get that data! Thanks in advance.

Dumb question...have you tried a different battery?

Yes..2 brand new ones

Let it sit overnight (or at least an hour or two) with the charging light on. Beyond that...I'm thinking you have a motherboard (or component on it) that's failed, thus kind of SOL on the data.

Nexus 4 - Black Screen and Red LED

Hi,
my nexus 4 stops working in just a day.
In the morning it was fully loaded and after pulling out the charging cable the smartphone shutsdown immediately.
If i try to power on the smartphone nothing happens. not even blinking red led. Even if i press power on or power on + volume down for long time.
If i connect an usb power and press press power on or power on + volume down for long time the smartphone led blinks in red.
I also measured the battery voltage. its about 4,2Volts. So nearly fully charged. Is also tried another battery which didn't help niether....
I have read many theads about this problem and i have tried many tutorials but nothing helped. I can't get the nexus 4 to get to the booting screen.
Maybe motherboard total damage?
Cheers
Christoph

How old is the battery? I suspect it could still be a battery issue.

The battery is about 2 years old.
What i have done now, i have bought a used nexus 4 with a cracked display.
Then i used my old case with display and battery and assembled it with the bought motherboard.
Problem solved now but i have no clue why the old motherboard keeps stop working...
