Hey guys,
I purchased my Xperia X8 back in October 2010 and have been using it to date. I think its a wonderful phone .. One problem, my USB connector seems to be faulty. It wont recognize my phone as connected unless I push the USB cable towards me, and have to keep holding it or have to put a book over the USB so it charges. I'm wondering does anyone else have that problem, and is there a quick fix to it? I'm going to mess with it for a while to see what exactly is the problem. Feel free to reply ..

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.
Hey everybody,
about 2 weeks ago I had to change the USB port on my nexus 4 because It wasn't charging. I went to a professional place and they replaced it. everything worked fine but I did notice a significant battery drain. poking around with several battery apps revealed that the culprit is "slimport wake lock". further digging around revealed that what probably happened is that during the replacement of the USB port, something now malfunctions with the slimport chip/connection and it stays constantly on.
I of course plan on taking the device to the laboratory and have the guy there take a look at it. unfortunately there's very little on the subject wherever i looked and I was wondering if any of you had something similar that can help me point the guy there. Also, I was wondering if there's any way to SHUT DOWN the slimport option (as I don't even use it) via the OS, developer options, some app or something else.
any help would be appreciated

Did u manage to solve this issue mate?

slimport is to connect to an external display via usb like MHL cable, i read that the usb hardware can be the reason, the guy replaced the usb port again in the links below.
make a cwm backup, and flash android again install betterbatterystats and see if the wakelock continues if so you should replace the usb port.
theory, the slimport pin is touching another?

Part is copy/faulty, see if they'll change it for another for you.
USB port was changed again, also did:
-Factory Reset
-updated to 4.4.3(and yesterday - 4.4.4)
-Battery change
No dice. I gave up and bought myself a Moto G.
Though, if anyone comes across a solution - do tell.
Seems to me like broken USB port or pinout not compatible. Possibly they did short-circuit on one circuit on PCB. What I can advise is go back to people who changed USB port and ask them to re-solder everything by using compatible parts.
Kind regards,
I have the solution guys... Though its hard to explain, its not very hard to accomplish.
I took my n4 for another try in a different lab. The technician from the start suspected it's not something in the charging port itself, so he asked me to leave the phone for him for a few days.
After 4 days of trying and learning, he managed to find that the problem is in the socket on the board itself is causing the problems, along with the charging port, in my case.
He replaced the port on the board itself and the problem is solved.
Eventually, I paid 40€ for this problem, not very high, beats the other option (buying a new phone)
Try it guys.

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!
My friend has recently started having problems with his G2. The problem is that the screen goes gray (you know, like old tv's when they didnt have any signal) when waking the phone up and couple of smacks against the wall seems to fix the problem mostly. The interesting thing is that the phone works perfectly while the screen is gray, he connected it to his laptop and was able to use it with somekinda program. But this is getting really annoying because its happening more and more often. What could be the problem? Broken screen, bad connection? Any help will be appreciated.
I have also been having this issue recently with my G2. I disassembled the phone and tried re-seating the video connectors. The phone did not exhibit the behavior for the remainder of that day, which was nice... but it started doing it again the next morning. My guess is the connectors are working themselves loose over time. Anybody have a suggestion on how to make the connections a little more stable?
