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...

Everything was absolutely fine earlier this afternoon (then the phone got a bit hot while riding in my car) and now, It is not being recognized by active sync or any power sources. The amber light doesn't light. It has happened before but then "fixed" itself. Anyone have any experience with this? This has happened both with the original ROM and the AP rom I am running, so I don't know that it is a software based problem. Any ideas? (Yes, I have it turned off, I have pulled the battery out as well, the USB feels no different than it did before).

Are you under warranty? Since this sounds like a recurring hardware issue I'd get it replaced. I've never had this issue, even when I left it on the dash of my car for an hour this summer, directly in the sun (by accident). The screen protector bubbled up and it was almost too hot to hold, but it started right up and hasn't had any problems.
Have you tried a hard reset?
Definitely no warranty (this is one that I did the screen replacement on and worked flawlessly for over a week with no problems. It did this before the screen was broken as well.) I noticed that it does feel a bit loose (the USB) so I am opening it up and going to check the solders. I know I'm crazy for doing this but it's out of warranty and it is already broken, so.... why not? And yes, I've done a hard reset and it still is giving me fits.
-Will
well....
All solder joints seem good, no inordinate resistance, nothing out of the ordinary... the problem is further up the stream I am guessing.... so right now, it looks like I'm down my Advantage. May just end up selling it off for parts and getting a Diamond or some such for a replacement (can't afford another X75xx series phone right now...)... Brand new screen on it, and everything worked fine for a week but I think something in my car fried it... because my S621 died the same way recently... and my Asus PND fried as well....and all of them had one common thread. Being plugged in to my car for recharging purposes most of the time.

I sent you a PM. interested in it for parts (I also posted a thread about looking for parts)
Hey.
I'm wondering if someone can lend me a hand here. I was rock climbing last weekend, left my phone in my jacket pocket, and I suspect someone may have stepped on / thrown my jacket.
In any case... it's not working right now. It doesn't start up, and there's no light when I plug it into the USB/wall chargers. Any hints on whether this thing is totally trashed? The phone was in its case the whole time, and its exterior looks completely undamaged as far as I can tell, with no scratches, etc. Another possibility is that it got rained on, but I highly doubt that the water penetrated the outside of the phone (especially given that it was in the case the whole time).
If anyone can help me getting my phone working again I would be eternally grateful.
you're kidding me,right? your phone doesn't start,no led comes on when you plug it in,and you want someone to tell you if it's trashed? did you check that the battery is properly seated?
hey whats going on? Heres what I suggest, take it to the tmobile store and tell them that the phone was charging and it started acting funky so you turned it off, and than it never came back on. From there they will switch out your battery, than if that dosent work they will just give you a new phone right there in the store. Long as no water damage which i dought it does. Just do that and you will be ok, I have done that many of times lol.
>did you check that the battery is properly seated?
Yes. I also wiped the contacts on the battery and the device.

Unfortunately it isn't quite that simple for me. I live in Canada; I purchased this phone several months ago basically new off eBay (it was used for a couple of weeks). Funnily enough, my iPod which was "naked" in the same pocket as my phone is also undamaged and continues to function normally. Are there any tests I can do to better determine the location of the problem?

You're gonna need some technical know how. Open the phone and check the mobo for any disconnected cable and/or water damage. There is really nothing you can do that you haven't already done from the outside of the phone. If possible, find a local repair shop and have them take a look at it.
Update: so basically I took out the battery, waited a day or so, put it back in, and all the buttons lit up on the phone (but the LCD remained blank and so did the charging light).
Took the battery back out, waited another day, put it back in, and the phone suddenly turned on and has been working fine since. Anyway, thank you everyone for your help.
Each time I dock my EEE PAD in the docking station I only have a 10% chance it will recognize the keyboard. Sometimes I get the keyboard only, sometime it recognizes the keyboard and the mouse (pad) but mostly it recognizes neither. Sometimes it says it is connected to the docking station and still doesn't recognize the keyboard but mostly it says it is not connected to the docking station after insertion.
I called ASUS support - they had me reset the transformer (Hold volume 'down' while hitting power) and also do the Factory Data Reset. Curiously while on the phone with them the keyboard just started generating 'd' keystrokes over and over! Finally they sent me instructions for updating the firmware, which I was to do myself. I did not research how to do this last step because I think it is completely unnecessary: the latest version is 8.4.4.5 and I already have that version. I called ASUS support back but they say their computers are down and call back tomorrow. However, the last thing he said was I will have to send it to their repair center in CA.
Basically, two questions: 1) Do you think I should download the firmware anyway? 2) Has anyone else experienced this issue?
I am not a genius but I would try reinstalling firmware. Maybe you got a bad firmware in your keyboard?
Fascinating is it not?
Not trying to be too simplistic but you might also make sure that the thing is really in there good too. The connection between my tablet and dock is pretty tough to get just right and the only way I really know for sure it's in there is to pull up on either side of the screen to make sure it's seated properly. I can imagine if one was more finicky then mine it might look like it's in there, latch slid and all, but still pop one side out if you tugged.
Just a thought based on my use.
I noticed the same thing...it's easy to think the dock is in correctly...it has to "click" and the little bar has to go ALL the way to the right side of the slot..otherwise it's not making 100% contact.
I had a broadly similar issue with mine. I eventually got the retailer to accept it back as faulty and ordered another [from a different supplier so it was from a different batch] and have had no issues with the new one... so far!
I am quite conscientious about docking the tablet solidly in the docking station. I use both hands (on each side of the tablet) and push firmly till I see the silver clasp pop completely over to the right. I have tried tugging it out afterward and neither side will budge upward.
Bottom-line is ASUS created an RMA # for me today. They want only the docking station, and not the tablet also. (My concern is what if the problem is the connector on the tablet?). One of the three main reasons I purchased ASUS was reliability, yet this is the first computer I have bought which failed out of the box! Anyway, it's nice to have prompt support and service. I called them 3 times and got through in less then 5 minutes all 3 times.

1.It can't hurt.
2.Nope, all is well here.
I bought this thing first off of Amazon, and it was backordered... So I canceled and ordered from Newegg. Fine, i have to pay for shipping, and wait longer, but whatever.
I get the tablet, so excited, and i notice first that the screen would switch orientation when it shouldn't have. Like if i have it in landscape, then lay it flat on it's back, it would go into portrait. This could be recreated every time, so it wasn't just a fluke. I installed Asphalt 8 Airbourn and tried to play. I held the tablet flat, then all of a sudden when the car took off, it took a sharp right and ran straight into a wall.
Great... the accelerometer is broke. Also i can see the backlight flickering a little bit.
I request an RMA from Newegg and they said it'd take probably about a week to get it back. Get it processed, about to go take it back and check their site to see if it's in stock still and it's sold out. I get on their chat to make sure and they said it's backordered, so i'd have to wait for it to come in or switch it to a refund. So i switched it to a refund and by that time, Microcenter in my area had them in stock so i dropped by and picked one up.
Go it home and it was acting fine, until i installed Asphalt again and then it ran the car into the wall again... Also, again, i can see the backlight flickering. Starting to get depressed, i contact Nvidia asking if this is a common problem and then they said it was the first they'd heard of it. They tried Riptide GP2 and said it worked fine on their test tablet. So i bought Riptide GP2 with my Google Opinion Rewards and tried it, the little water craft ran straight into the wall, just like the first tablet. They told me to try exchanging it again, and that they were sorry that i was having trouble.
I go back to microcenter, demonstrate what is happening, they give me a new tablet and tell me to install the game and test to see if this one does it before i leave with it. Their wifi was being crappy, so they gave me a USB Ethernet adapter and an OTG cable to connect to their Internet (it worked instantly, freaking awesome.)
Install updates, install app updates, install the game, it works... Finally have one that the Accelerometer works... I leave and go home, and the screen still flickers on this one too.... So thats the question part of this post, does anyone else have this tablet and notice the backlight flickering? It happens more often on darker brightness settings.
Other than the problems trying to get a working tablet, and the screen flickering, i love this tablet. The screen is really sensitive though, so when you're holding it and trying to hit edge of the screen, and you're barely touching somewhere else, it'll usually give you a hard time. The stylus is awesome, the screen can be very bright and easy to see out in the sun. The 1080p is a noticeable different over my 2013 N7 ( i can see the pixels in this tablet, i have very sensitive eyes and the ability to see very fine details) but it's still a great screen. the battery life at least for me is not as good as the 2013 N7, however it does make it through the day.
anyways... TL;DR: Love this tablet, had a pain in the ass of a time getting one that worked though. Also, does anyone notice the screen's backlight flickering like i do?
is it a continuous flicker or is it just slight changes in brightness when the screen content changes? there is a known "feature" called prism that does some kind of auto/dynamic brightness/contrast adjustment depending on whats showing on screen. there's a thread over at geforce.com about it. apparently it was introduced in a prior update on the other shield devices too so im hopeful its fixed. if its a true flicker and not just brightness changes, then its either defective or the backlight is pwm and you can see it. some people are sensitive to pwn backlights on regular computer monitors and can see the flicker. google pwm backlight if you're unfamiliar with the phenomenon.
It happens when the screen content changes, and i figured it'd be some kind of dynamic change.
it also happens when the screen has the content on screen constant. It's sort of like a pulse, sometimes it also gets bad for a split second. I don't really know how to explain it. it will be pulsing, then it will have a bad flicker then go back to pulsing. It gets worse the darker you make the brightness, and also when you turn on autobrightness (although im sure this makes it worse because it's trying to adjust the brightness in dark light).
I looked up the pwm backlight and it looks like it's mostly with LED backlights. Thats my guess of the backlight on this tablet. That makes sense though, because i can see a VERY VERY slight pluse on my work's Macbook Pro, and a slight pluse on my Nexus 5 too. I suppose that this might be the case.
I just don't see it being a defect because i've had three of them, from two different vendors and they've all done the exact same thing with the backlight.
I haven't noticed any screen flicker.
I am also comparing this forum with the N7 (2013) forum when it first came out.
Lots of people there seemed to have troubles getting a good one -- light leaks, touch screen issues (there were several firmware updates for this), dead pixels, etc.
At least so far, there seems to be fewer people (per captia) complaining here.
Speaking of touchscreen issues, I did notice something about my Shield Tablet...
I was using it in the evening, while connected to a charger. I suddenly had a terrible time typing. I had just installed Thumb Keyboard, so I thought that was the problem. Went back to the Google Keyboard. Still had trouble. Scrolling web pages was also slow/erratic. Reboot -- same thing.
The next day I took it to work -- lots of email, including lots of typing.. general usage, etc. --- all with no problem. Back at home in the evening, some games, Google+ (typing) -- no problem.
Later on I was surfing eBay, and again I could not type or scroll without a lot of problems.
I turned on Settings --> Developer options --> Show touches and --> Pointer location.
With my finger steady on the screen, it was showing lots of erratic movement, particularly in the vertical axis. Several mm of vertical error, and about 1mm horizontal. Sometimes clearly below the entire area my finger covered.
Then I realized that both times it happened I was connected to the charger (Travel Surge protector with 2 -- 2.1A(shared) USB outlets).
I disconnected the charger, and the problem went away.
Connected the charger, and after a few seconds, the problem returned.
I was using the included cable, and another 2.1A rated charger.
I changed to a different 2.1A rated charger, and did not have the problem.
Different cable, 1st charger -- No problem.
The problem is reproducible (although not always) only with the 2.1A travel surge protector, and the included NVidia cable.
I noticed that this thing will charge at nearly 2A. The included cable is quite long (as compared to the other cables I have laying around), but is not thinker. In fact it is thinner than other USB cables.
It's really too small a wire guage to run almost 2A for that length.
It is marked with the Shield symbol (Like the controller or the Shield Portable), and came wrapped in a thing that said "Use with", and the Shield controller symbol.
Was the wrong cable in my box?
How are other peoples cables marked?
Has anyone else noticed an erratic touch screen if you use it while charging?
Mine is marked the same as yours. I just notice the screen keeps poping on while it is charging for no reason.

Yeah, there are a lot of devices that will freak out when you're using different chargers. I was going to tell you to go back to the Nvidia cable and charger that were included with the device to see if that fixes it, but it looks like you've found out that the charger was the issue.
I'm still unable to tell if it's the PWM Backlighting method that was brought up earlier or not. I can't get anyone else to see it though, and after three devices, i'm starting to feel like it's something that is normal.

Same thing happens with mine. While charging the screen will frequently come back on and then go off again in a few seconds. I haven't noticed the behavior when it's not charging. It's almost like something is running in the background causing it to wake up when charging.

I've noticed it slightly in low brightness but not as bad as the Tegra3 based N7 and TF700t. I'm guessing it has to do with prism if that's the case.

Screen "Flicker" is the auto brightness, try changing to a manual brightness. I have noticed the orientation is very sensitive, sometimes when sitting down or moving a bit it will flip orientation on me, seems overly sensitive, whereas ive used other tablets that were not sensitive enough. Sounds like you may have had a few bad ones but the screen "issue" seems to be common, the light sensor seems to be overly sensitive (assuming changing to manual brightness resolves your case).

I haven't noticed any type of flickering on my TN7 or my new shield tablet. This could partially be because most of the time i have the brightness setting to manual. Its seems as when i have it on auto the screen is just a little too dim for me. Although, when using the tablet outside i usually have it on auto and the screen chooses the correct brightness so it can be best viewed.
As I mentioned, I haven't seen anything I would call a "flicker", but I am glad someone mentioned the auto brightness.
To me, the auto brightness seems a bit "hyper" -- too much gain.
A slight change in orientation to or away from room lighting causes a drastic change in screen brightness.
The same for a shadow from my thumb if I hold the tablet in landscape.
I guess it could cause a flicker, but it depends on the context of timing --- Kinda like "the dinosaurs died out quickly", vs. "the quark decayed quickly".
Also I want it to be clear that I am not complaining about my Shield Tablet. It's just that xda-forums are a place where things are discussed in minute detail. It is not a problem, issue or complaint.
I have no interest at all in using my Nexus 7 (2013) (or any other Tablet) since I got my Shield Tablet.
The weak wifi appears to be the priority focus Nvidia is now giving the tablet. Question is will they go into denial mode like Asus did with the T700, or address early and revise the design IF needed. Sales were badly impacted for the T700 and a high return rate, per Best Buy.
Hopefully a simple firmware fix, but weak wifi is almost always antenna related for devices like this.

Tell me about it. Its been like that since I first turned the tab on 3 days ago. Nvidia refuses to acknowledge my issue and insists I pay return shipping and a restocking fee. I don't understand why I should pay more than every other customer just to get a properly working device. Nvidia has pushed me away from sticking with this tablet.
The flickering when the content changes is probably Nvidia's PRISM at work. Basically, it tries to optimize brightness and colour so that power usage is reduced.
Instead of maxing the backlight and telling the pixels to display dark grey, it dims the backlight and tells the pixels to display light grey, saving power.
It is an advanced form of autobrightness, and I think it can be disabled. But a continuous flickering should not be caused by this. This should happen only when the screen is refreshed.. like new page or picture

That IS a probelm.. for some reason the bottom is getting clipped and being sent to the top.. send them a picture.
I don't have the flickering problem either...but the tablet used to wake up constantly when charging ...but after I did a factory reset everything is fine now .... My only complain is the poor WiFi performance
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!
