Was using it when all of a sudden the screen turned off, rebooted and I could hear the booting sound but no screen was not showing anything. Gave it to a repair shop but they said that the screen was broken. Is there any way to fix it. I read somewhere that the screen's cable may be loose from the power. and if I plug it back in it might work. Please help.
Tried going to recovery mode, download mode. but not working. tried connecting to computer. I tried everything.
I don't know how to get into the N7, perhaps a Google search.
But once you are in, you will see ribbon cables laying flat and going into small plastic blocks. Push the connector with a fingernail on any cables you can access. Especially look for any cables going to the screen.
Sorry can't help anymore than that.

I'm not sure how the repair shop determined the screen was broken if they don't have a replacement part to test. But the screen is certainly the most expensive part, and you can see why they want to replace it. Here's the thread that shows you how to take it apart and reconnect if your cables happen to be loose. But first, shine a flashlight on it in a dark room while turned on. If you can see the display from the flashlight, the back light is faulty. Second, if you have a slimport adapter, get it connected to a TV (newer models). If the page shows up there, at least you know the GPU is still good.

I watched a disassembly video and managed to open it. And removed and plugged in all the ribbon cables plugged them back in. and rebooted. Still not fixed.

Tried everything you said. Cant see any light from the screen. I think the screen has died. Touchscreen, speaker everything working fine. Only the screen is broken. You said I could connect it to an external display. What cable do I need? I only have a data cable. I'll have to buy the cable. Also can I use external display without doing settings on the phone first?
Thanks.

You flash a light on it to see if the screen has any display. You're not looking for any light, but the regular display of icons, etc... The back light is what illuminates the screen. Without it, you can't see anything unless you shine some light on it in a dark room. If the screen has died and you see nothing,how do you know the touchscreen still works?
The device is called slimport. If you plug it into the charging port, and connect it through an HDMI cable to your tv, it'll show without your having to do anything. Keep in mind that older LCD tvs might not work.

Scenario 1hone unplugged (meaning not connected to usb cord).
Battery icon on the notification bar shows that it is charging but it isn't. Since the status frequently changes from charging to not charging, the LCD screen won't turn off. And when I turn off the the phone, it shows the battery icon (the one that shows up when you charge the phone while it is turned off). The phone is not even connected to the charger, so why is it showing that?
Scenario 2hone plugged (connected to usb cord and charger)
Battery icon on the notification bar shows that it is charging. Since it sticks to that status (charging status, i mean), the LCD screen now ables to turn off. It also properly charges it self.
I thought that maybe the problem is with the ROM i'm using. So I wiped data and cache and installed a different ROM. It seems that the problem is not with ROM but probably the hardware. Can anybody please help? I already searched the forum regarding this issue but there's none like mine.
The phone is more than a year old so no use on the warranty. This is the first time this happened on the phone. Please help. Thanks. T_T

Most likely there is something wrong with your usb port. So more a hardware than a software problem.

This seems to be a common issue in the S2 threads as well...in almost every case it's been solved by replacing the usb board....having replaced this board in my wifes S2, I have *some* practical experience of this (yes I know that my experience is with the S2 and not the W). I'll look into it and see what I can find out. .....

Ok...so as this video shows.......
https://www.youtube.com/watch?v=ZjcucJDzfmk&feature=youtube_gdata_player
it's going to be way more expensive to replace the usb socket on the W than it is on the S2 due to the fact that the W's usb socket is attached directly to the main board instead of being separate to it (as in the S2)......
Sorry to be the bearer of bad news.....but unless you're prepared to unsolder the socket from the main board and replace it yourself, all you can do is replace the whole main board.....muchas deneros

Yes. This will be very hard to repair and the chances are high to cause more demage while trying to replace it or to solder broken wires.
As long this is because of broken wires on the PCB and the micro USB plug is in good condition I found the following solution to work best. First make sure the usb plug dosn´t move on the pcb. Else use some superglue to fix this, but be carefull the glue doesn´t flow inside the plug. Secound use some fine sandpaper to remove the layer of isulation paint where the wires are broken. Then use some conductive silverpaint to connect them again. After the paint is hardened use a needle to remove the paint "between" the wires, so there is just paint where it has to be to connect the broken wires. Use a DMM to check the connections and to make sure there are no connections beteen all the other wires. When you are done check if the USB plug is working again like expected.
My phone won't turn on. I own a samsung galaxy nexus (verizon). I've had it for 16 months. I was talking on my phone then ended the call. Had it charging to the wall. Set my alarm for the morning. When I woke up my phone was off. I tried to turn it on. No luck. I did the 10 second volume down plus power button. Still nothing. I pulled the battery and did the wall charger no luck. I plugged it into my computer with the usb. It doesn't register it. The phone has no lights on it. The screen doesn't light up notifying me of it charging. The little flasher light on the bottom doesn't light up. Please help I'm out of options. I called verizon and they said i'm off warranty. I have no other options that I know of besides to get a new phone. I love my phone. I unlocked and rooted it. I have everything on it. I need to get it back on. Any and every idea will be tried. Thank you!!!!

Question: Did you use the same USB cable from the wall charger to the computer?
Could be a couple of things...if the answer is YES, I would change USB cables and see if that fixes it.
If the answer is NO, you could try to clean out the microUSB port. It's possible that some dust got into it, causing a small shunt or keeping the pins from connecting. I know my previous Galaxy Nexus had this issue...found out I had a piece of lint that somehow got into the MicroUSB port and kept the USB plug from seating correctly.

tkirton,
I used a different charger than the micro usb cable. in fact i used multiple different chargers. I also blew out my usb ports and cable. I tried again and again, using different usb ports as well. it didn't work. My computer just doesn't seem to identify the cable or phone like it use to.

If you have exhausted all possible means then the last resort for you is to try the USB jig. Usually it can wake the device up and put it to ODIN mode. If that fails too, then its a possible major hardware failure.

Question , when you connect the charger, does it light up the battery symbol ?
Have u tryed to "center "the phone usb port with a needle or something like that ??
if not plz try this :
1) turn the phone off and take the battery out
2) take a toothpick, knife , pin or whatever will fit into the micro USB slot of the galaxy nexus.
3) VERY VERY slowly make it so that the little shelf like connector is in the middle.
4) connect ur phone and hope it gets back to life

When i connect my charger i get nothing. no symbol no lights no response. and the centering of the usb charger didn't work either. my phone has such a tight fit i couldn't even fit a thumb tack pin into it.
I've done lots or research on the USB jig. I'm going to try it. or find someone that has one. wish me luck!

Good luck. USB Jig might be your last resort before you send it to repair.
A few days the phone stopped being able to charge while on/off from both wall/USB. Suspected it was due to the flex. Ordered one off of Ebay and when it came it looked identical to the one in the phone. Phone is about 14 months old so no more warranty (got it at IO 2012)
I did the standard instructions of removing the 6 screws with the battery and SIM card. Prying off the back cover, removing the screw for the bottom module along with the ribbon.
Disconnect the antenna, screen ribbon cable and the ribbon cable to the flex from mainboard. Replaced the flex underneath the vibration module and closed it all back up making sure to connect the 2 ribbon cables, the antenna and the cable from the bottom module to the flex but it still won't charge.
I can get it to be recognized in computer as a MTP/PTP device but it still won't charge from computer or wall while on or off. Is there anything else I can do or is this gone forever. Tried a factory reset as well but still won't charge, it was originally just running stock 4.3. Thanks.
EDIT: Battery under Settings says charging at the bottom but not at the top...

Get yourself a wall charger and 2 batteries. Rotate them.
For files you can use bluetooth, NFC, drop box, drive, copy , flicker, box, etc...
Edit: never mind. It connects just doesn't charge.

Yea to clarify before I changed the flex, the phone couldnt connect be recognized by computer on USB. Now I have at least that but nothing else.
I have the same problem but my nexus is already in warranty, so I try to resolve this problem with samsung!
my problema is backwards
After replaced the USB flat i can charge the phone, but the computer not recognizing
I have the exact same problem. Replaced flex cable, still no charge. My pc recognized it with the old and new charge port as well. I had to re-activate my OG Droid until either the new HTC and G5 phones come out...sigh
long shot, but clean-up gold phone contact points for better conductivity?
Same Here
I think it happened after flashing 4.4.2 roms, i tried to flash different roms different cables, wall,pc,ps..nothing worked if it is on.When i turn off the gnex it is charging..Anyone?
I think i have solved mine
Well it was getting really weird like discharging while it is connected(turned off). So i thought it is not related to rom. So i wiped dalvik cache and now it looks ok
Any news on this topic? I've got the same problem, swapped the USB flex cable and it still isn't charging. I can connect via ADB though and in the battery details menu it says "charging" at the bottom, although it obviously isn't.
Before everyone starts accusing me of not running a simple search, take it easy, been done. And yet, nothing to help me on the matter.
So here's the thing:
Her phone won't charge. Not when plugged into the wall, BUT when I plug her phone into the computer it is recognized and allows file transfer and everything, but just that - it still won't charge.
Here's what I've found out so far:
- Not a problem with the charger: I'm using the original charger, and it works flawlessly on my own Gnex running PA 4.4
- Nothing wrong with the battery: swap batteries between phones, my phone works fine with her battery, her phone still won't charge.
- When her phone is completely OFF and I plug it in to my PC, it plays the sound of connecting and disconnecting a device, and prompts that it doesn't recognize the USB device. If I tap the power button for a second while it's off (not holding it long enough for it to turn on), it does the same thing connecting-then-disconnecting sounds and "doesn't recognize the USB device".
So - has anyone ever run into this problem before? Know how to fix it? I know the chances are it's just a hardware malfunction, but it's weird because of the ability to transfer files- usually the problem is the reverse.
In the meantime we're using my phone as a charger for both batteries untill we get the spares and wall charger we ordered, but it's a real pain.
Just trying to find a better solution than taking apart the phone and try and fix it or just ordering a new Nexus 5 (which is tempting, but don't really have the money to spend on it...)

Its the micro USB port the pins are bent homie.
Some pins allow charging some allow data transfer. The ones for charging are damaged in your case.

Yup. Just this moment after a really really really close examination of the port and comparing it to my own phone, one tiny half a millimeter peice of metal is bent out of place and broken. Gotta order a new port ASAP and try and change it.
Thanks mate!
But hey, look at the bright side... a fun home project to immerse myself in instead of prepare for my finals! :laugh:

Back with worse news. Just replaced my wife's micro USB port on her i9250 GNex, and.... same thing. Still won't charge, computer recognizes it. Now I'm completely baffled. Thought for a moment that maybe I had been such a fool as to have put back in the old port, but unfortunately, it wasn't my stupidity.
Ideas, anyone?
Saturday night I had my phone on the charger overnight. When I woke up, it was still low and had not charged. I played with the cable and got it to start charging, but not properly. I figured it was probably a bad cable or charger, not sure why though. So I used a zero lemon case that worked fine. My charger in the car worked okay too. Fast forward to this morning and the phone now displays as being plugged into usb and charging something - see attached. Plugging in any other chargers changes nothing. Powering off will show a charging icon. I doubt it's a software issue but it could be I suppose, but I suspect I have a bad charging port. It's currently wireless charging, but still displaying the message in the status bar. Stock ROM, custom kernel. Any ideas? I will probably try a reflash tonight to see if it changes anything. Edit: not a kernel issue, switched kernels and same issue. I'm almost certain this is a bad usb port but I've never experienced a bad one before.
Is it still attached to the Zero Lemon case? It looks like the phone is charging it. If nothing is attached, then the port might be goofed. Did you try cleaning any lint out of it? Use a toothpick or plastic dental flosser. DO NOT use a paperclip or anything else metal as it could damage the port.

Have you tried a different wall charger, reversing the cable, same cable different charging block, etc? Does the notification persist all the time, only after it's plugged in, does rebooting remove it?

I have, three different chargers, all with different cords. One of them is the same cord I used to connect it to a PC a minute ago, and USB and charging work when connected to a PC. Reboot does nothing, the notification persists until it's plugged into a PC.
I had this issue too, was freaking out. Cleaned the USB c port with a dental pick and got some lint out, still no good.
So...I powered off the device. Wrapped a thin layer of iso alcohol wipe on the dental stick and cleaned as good as I could. After a few seconds of drying, used a aerosol duster to blow out the port.
Been fine for months now.
An update, in the usb preferences screen, if I select USB controlled by this device, it will charge normally. Seems more like a software issue, but if it's acting weird when off, would it be? When off it would indicate a firmware or hardware issue. At least I would think.
Had the same thing happen to me, its a faulty use port. Contacted support and they got me a new phone. The only bad part is you gotta have a credit card to have them send it out

Please don't use a toothpick to clean USB ports. I did that some time ago and broke some pins, just slightly, so it sometimes worked, sometimes it didn't. Replacing the jack (was a different waterproof phone) was a pain and cost a quite a bit of money.
Try to wash it down with alcohol and blow it lightly with compressed air, several times.

I had to RMA my P2XL and I did the option where you send it in then they send the replacement. I think they send the replacement once they see the original has been shipped. I dropped mine off at UPS and the next day I got an email saying my replacement was being sent out.
