So here's my dilema. The transformer is on, I know cause I can plug it into my PC and it's detected and I can ADB into it. Only problem I have is the screen does not want to turn on. I've rebooted it and nothing, no asus logo no loading screen or anything. Is there anything that I can do or that it could be?
thanks
I had the very same problem, unfortunately it seems as though the only option is to r m a your tablet

Can you tell if the back light is on in your tablet? If it is, a cable has come loose, I wrote a quick guide a week ago, I'll try to find it, but search is disabled right now.
Edit: http://forum.xda-developers.com/showthread.php?t=1522637
what's the warranty length on the tablet? I'm approaching the 1 year mark.
No backlight, or flickering or anything. Just looking at the tablet is as if it's not charged/powered on. Only way of knowing anything is happening is when it gets detected by my computer.
Thanks for the replies.
It depends on your warranty card I think, correct me if I'm wrong, but they are usually one year. If you have an HD TV with an HDMI port, and you have an HDMI mini cable, try that as well. If it works, probably just a cable loose. Asus didn't do a good job of making sure nothing comes loose, and a drop from any height or any small bump could cause the tape on the display cable to slip. I've heard plenty of horror stories of Asus RMA as well.

About a month or so ago I started having trouble with my transformer. When I would try to charge it, it would take several attempts before it would indicate that it was charging at all. I assumed that it was either the wall charger was going bad (as quite a few people seemed to be experiencing that) or the USB cord itself. 2 weeks ago, it stopped charging altogether, or at least I thought so initially. But after A couple of days I realized that it it was charging but there was no indication of it doing so other than the screen brightening for a split second when it was first plugged to the wall. I also start plugging it into my Pc's (A windows 7 laptop and PC and an old XP PC) I get a little pop-up saying "USB device not recognized". Ok, so at this point i'm assuming that it's a USB cord issue as there are problems with connecting to the PC and wall charger. So, just get a new charger and USB cord, right? Right. So yesterday I finally located an office depot that sells them, got home super excited with my new charger, plug the cord in and..same issues. WHAT THE FRACK!??! So now I'm thinking its either a issue with the port on my eee pad or a software/firmware issue of some sort.
A couple more details, I think the issues started around the 3.1 android update, not to say that was the cause of it. Also, I've doing a factory restore, uninstalling the asus suite and drivers and re-installing them and I've also updated to 3.2 (yesterday) still, my issues persist. Sorry for the long post and if I've posted this in the wrong spot, I'm just at wits end. help me obi wan you're my only hope...

You had a good stare at the port on the tablet with a magnifying glass and a light to make sure nothing's in there? Could be something as simple as a bit of detritus causing this problem. Might not be, but worth a proper look.
Did you install the drivers for the TF on your PC?
Also, which store is selling the charger and USB cable?

That is my next step, gonna take a look at it this afternoon under a chem lad magnifying glass. thanks.
Yes I did, uninstalled and reinstalled a couple of times. But I don't even think it should matter, as the computers should automatically see it as a storage device at least.

Couldn't notice anything after looking at it under the magnifying glass.
So... My Transformer has a bit of a bug, where when I am charging it or the charger is plugged (separated or in the dock), the touchscreen would become unresponsive unless I also touch the metal of the Transformer with my hand simultaneously.
Now, that Tablet is about half a year old and it suddenly happened from one day to the other.
Naturally, I researched it first, and I found that a few people had similar problems. Suggestions ranged from completely discharging the battery to updating the Tablet - I tried them all, they all didn't work.
So, I send in a request to ASUS support - in the UK, and after a bit back and forth (like asking what version the Tablet was running at), I was referred to their exchange and repair-service.
So I contacted them, and it seemed to work out quite well. The tablet was collected and I included the charger as well as a description of the issue.
At some point I got an answer - in polish, for whatever reason - that told me the tablet was repaired and sent out. A bit weird that it was in polish, but oh well, I can deal with it.
So I finally get it back, wrapped up very nicely. With a little note (in English this time) saying that no issue was found. Awesome. Maybe you could've informed me via Mail before just... Sending it back with that note. Maybe I could've helped them to reproduce the error.
Needless to say, as soon as I plugged the tablet in, the error was back. They reset the Firmware tho. Nice guess.
So yeah, stupid support, not helpful at all. I will consider that in future purchases. -_-
Just to point out the obvious. How do you know it's not something YOU are doing?

I don't know what I COULD do to make this happen... I mean, there's not too much you can do wrong with plugging in a cable.
have you tried pluggin it in at a friends house?
It could be static build up. Perhaps your house has carpet that builds up static when the air gets dry from running the heater. Since the screen operates by capacitance from your fingers vs. pressure, this could be an issue if you are holding more than the expected charge. Do other people experience this issue with the device? How about if you use it in different locations?
My Nook Color will double or sometimes 10X enter a keypress when I use it when it is connected to the charger. The fix is to not use it on the charger.
Did you try to change the charger plugged in the wall socket ?
I mean turn around.
It sounds silly but I read about people get a little "shock" if they touch the tablet when the charger plugged in, depending how it is put in the wall socket.
Maybe you will see a difference.
I had to send mine after less than a month having it because something appeared between the backlight and the screen.
I got it back one week later with a dead pixel right in the center (and lightbleed) and left speaker not working.
I sent it back and got it back two weeks later with working screen and speaker but a lot of lightbleed.
I then gave up on sending it back again and learned to live with the backlight bleed which is present at least one third of the circonference of the screen.
So I mean yeah they will fix it to a degree but don't expect perfection...
So first off, i know that Android L is a developer preview and would have some issues here or there. some apps would crash and what not, I got that. i have had L on my Nexus 7 since day 2 with minimal problems at all. Last night at work i turned my tab on to find a static screen and nothing worked. i could hear it unlocking, but it was just static. after about an hour trying to get some of the screen, it came too but with all the colors off and running extremely slow. When I say slow, I mean i would press an app and it would take anywhere from 3-9 minutes to pop up if at all. I can't get it to go into the bootloader to get back to 4.4.3 or anything. As of right now, this Nexus is rendered useless to me and I HATE THAT!!!! if anyone has any insight for me i would appreciate it. Thanks

That is a loose ribbon cable that causes the static screen. You can remove the rear cover, using a fingernail, & disconnect the battery, press the ribbon cable into place, & then reconnect & reboot. You can check out the dismantling guide, or the "Possible touch screen fix" thread". No seals are broken & it is fairly simple to do. But that is how you know it is HW, not SW related. If it were SW, bootloader or recovery would work. I had this same issue along with touch screen issues, months ago & that's how I fixed both issues.
Oh awesome, I'll try that out when I get back home. Thanks for the quick response

you, my friend, just saved me from throwing my nexus through a window! it turned out that the gold ribbon cable, laying over the batter, came undone somehow. but it is now fixed and i can stick on L for a bit longer! THANKS AGAIN!
So I have an issue with a 2012 N7, warranty is long gone. I've tried all suggestions from billykxda's thread, but no luck thus far. I've also tried Google's official page on the topic as well.
I've left the device charging for many consecutive hours, both via AC power and USB, and I suspect my issue resides with the LCD screen. Also tried a hard battery pull. It's also important to note that I haven't undertaken any mods on the device at all, i.e. the bootloader is still locked and USB debugging is not enabled yet.
When I plug the device into my PC the Win7 driver notification bubble pops up, usually reporting either an Unknown Device or an "APX drivers not installed" message. I'm unable to get it to boot into Fastboot, Recovery, or Android OS. Plugging/unplugging the device via USB yields these driver messages over and over again, along with the Win7 sound notification, so the device isn't totally dead, but no amount of button combinations or 30-60+ second button holds are getting any response.
Has anyone else experienced these issues before? Do you think my device is totally dead?

Yes; I am also experiencing similar issues. Unfortunately, I have not reached a solution. I just replaced a broken screen for a friend. Once I got the screen in, I tried turning it on but didn't see anything happen. I began to research and thought I had the dead battery issue that most people get when leaving it unplugged for an extended period of time. I plugged it in using the wall adapter for a few hours, used the power+volume buttons and still didn't get any response. Finally, I decided to charge it with my PC. The PC recognized something was plugged in, installed drivers, and now I have a Nexus 7 in my connected devices list. While connected to my PC, I hold power+volume down and hear the USB disconnect, reconnect, and have an unrecognizable device attached. This leads me to believe that the Nexus 7 is working properly and the screen is not working. I have taken the entire device apart to re-seat all connections 3 different times and still cannot get it to work. I hope someone can shed some light on our issues!
Edit: I forgot to mention, I also tested the battery with a digital multimeter. It reads approximately 3.79 volts DC. I thought it may be important to state this in case the issue is battery related. I'm not certain what the correct value should be for it to work properly.
I am currently trying to diagnose this problem. Yesterday, I hopped on Craigslist and bought a working Nexus 7 for 50$. I am currently taking it apart to rob parts from it and figure out where the problem is. So far I have tested the battery. The battery reads approximately 3.78 volts DC so I can probably rule this out as my problem.
Also, I noticed something strange yesterday. I took the broken Nexus with me when I went to meet up with the man selling the used/working Nexus. While I was outside in very bright sunlight, I pushed the power button on the broken Nexus. I noticed that I could actually see the screen doing something. It was all fuzzy and had lines running every where, but you could in fact see it doing something. I think the replacement screen I received is bad, but I won't know until I start swapping parts.
AvidPhisherman, for now maybe try taking your Nexus out in very bright sunlight and see if you can see the screen do anything when you press the power button. Also, I'm not trying to hijack the thread. It seems that we have very similar issues. I hope to find something that fixes both of our problems.
Success.... kinda. I tried combining the broken Nexus 7 motherboard with the working Nexus 7 screen but it wouldn't fit since one is the 3G model, and the other is the Wifi only model. Next, I put everything back together on the broken N7, but this time I used the LCD ribbon cable from the good N7. Success!!! It powered up, and I can see the screen. My problem now, is that the screen is mostly unresponsive and acts like you are touching it in random spots, when you're not touching it at all. I'm taking it apart to re-seat the connections... again.

Hey redfox thanks for taking in interest in this! You're not hijacking the thread, your posts are very helpful. Good to know I'm not the only one experiencing these issues.
I'm just a hobbyist with an interest in fixing things, although I don't have much experience with DIY fixing. I didn't have a chance to try turning the screen on under direct sunlight, but yesterday I took both my non-working Nexus 7s (the first one I mentioned in my OP, the second one just has a bad/hollowed out USB port) in to a repair shop for a free diagnosis. I'm actually a business user, my company owns the tablets but I'm responsible for maintenance/tech troubleshooting.
Please keep me posted with updates as to how your progress is going. I'll post again once I get a report from the repair shop re: my issues.
Hi,
I have been having the same problem,
I bought my wife a used Nexus 7 and it worked just fine for almost a year then all of the sudden the screen would not function
there would be lines going through it but it remain dark.
thank you for researching the matter i will try to buy the part online and see if i can get it to work now!
if i understand it correctly there is no need for a new mother board but just a new LCD ribbon cable?

I cannot guarantee that it will fix your screen, but it is possible. When I had this one out in the sun, it did the same thing. The screen was super dark, and I could see crazy lines. Hopefully a new ribbon/cable will fix your problem. They are only a few dollars on Amazon.com

Hello fellow users! Quick update, I finally heard back from the repair shop.
Bad news - they tried swapping out the screen, then the battery, USB charging port, display cables, etc. etc. and nothing worked. Their diagnosis is that the tablet has a fried motherboard, and they're unable to repair and/or replace it
Good news - it cost me nothing to receive this diagnosis
Hopefully the outlook is not so grim for your respective N7s. Just wanted to post an update as to what I learned from this whole experience.
Hi guys, Reporting in.
Toke a while but i got the part AND found the stupid device!
After ALOT of fiddling, taking apart and putting back again i found out that the problem was the battery!
it looks like it was on its last leg and that caused all the strange screen stuff.
I dont have another battery to replace it so instead i hooked it up straight to a USB cable and into the socket and it works just fine
thanks for the tips and hopefully this helps someone else!
Hello, I have had my Axon 7 for just over a year and two days ago the screen went suddenly half static despite the touch still working perfectly. I looked up the issue and saw that this is pretty common and that my display connector was probably loose, so I opened up the phone to make sure the connector was fully connected. Well, I booted the phone and the static was still there, so I unplugged and reattached the connector, but that didn't help either.
Given that ZTE is bankrupt and my phone is out of warranty, is there anything else I can try at home to fix this or is my phone screen just dead? I'm in California, is there anyone who could possibly fix it in the state?
Thanks for your time!
Try pushing the connector down while it's booting and see if that fixes it.

Alright, I'll try that. If it needs constant pressure I'm probably going to need to glue it or something?

Tape could also work. I added tape to my back up Axon so it doesn't happen again. You could also add something so the frame can push against the connector.
Hey, unfortunately, pressing on the connector doesn't change anything with the screen. I even tried disconnecting it and cleaning out the contacts with a can of compressed air. None of this helped.
What are my next steps? I'd really love to get this phone working again.
Thanks!
Probably playing with the wrong connector, the half static screen is common problem, ZTE repaired mine a month ago as they are still actually operating. They said it was a connector and that they put something in there to make sure it doesn't move again.

Hey, that's possible, though when I unplug this connector the screen goes completely dead. Here's an annotated image of the connector I've been messing with and the foam pad that was installed on the back of the phone, I believe to keep it in place (my phone was bought in March 2017).
https://imgur.com/0d7C2xc <- That's an Imgur link to the photo, I can't seem to get it to show up as a hyperlink or embed it into the post.
Is this the wrong connector?
Thanks!
Yep that's the connector. I'm sorry to say but it looks like the screen is toast. I seen some Samsung Galaxy S7's that have the same issue but couldn't be fixed without a new screen. And since the Axon uses a Samsung screen, that might be the issue.

Is there a place to get Axon 7 parts? I am not planning on using it as my main phone again, but if I could get a working screen I think I'd use the phone for something else. Are there any other screens that use this connector?

Aliexpress has screens for sale, they came down in price the last time I checked.
