I checked out a few other threads, on a couple forums and dont think anyone has been stupid enough to do this so far...
about 4 months ago, I was lost and my phone was dead, having bodged a car charger together I plugged it in.
The phone turned on, booted up and I got the SatNav software running, but before I could drive off it started flashing.. screen, lights, like a tiny disco....
Then it smoked, quite a lot for a second or two, by this time I'd took battery out and dis-connected the charger but it was too late, the phone was dead.
I got home, put the battery in a desktop charger til it was full and the phone has remained at it's current condition since.
So; it won't turn on, vibrate or flash any lights. The ONLY thing it does, is power up the right hand side bottom white light between the home key and back button.
I've been Ebaying since the day I killed it for a spares one, tried buying a main board but no joy anywhere without paying over £70 (and that's for a complete but knackered handset).
My dad's good with phones, his mate better also both of which said i've burnt out some chips. Some do kinda, have small 'holes' in, and I wiped a 2GB card too, wont work in anything else.
Without spending silly amounts on a new phone can I not do anything with this? Apparently everything except the main board should work (screen, digitizer etc)..
Help anyone please? -ta.
I suggest that you contact your local support team because I think this is something that needs to be examined at a repair center.

I dropped my X10a, and cracked the screen/digitizer. Is it easier to replace the whole housing or just the digitizer? Any suggestions on which company supplies OEM parts at the best prices?

ruh roh. Did this behavior just start on its own randomly? Sounds very similar to what mine was doing due to a failed USB port. I think there is at least one, maybe a couple more, other users on the forums here who also experienced USB port hardware failure. ended up doing a warranty replacement for mine.

Ya it completely started happening on its own.
Definitely seems to be the usb port.
Thanks for the heads up, gonna be contacting att in the morning

Yea that's a common problem. USB port defect.

I've already brought back 2 of these because of the same exact problem. I'm really starting to think it's because there is no cover/door over the USB port. Loved the slider on the cappy. Need a case that covers the port

There's a few threads on this. I personally started one. Best thing to do is just take it back to att.

While I certainly can't argue that covering the USB port is a bad thing, I carried an HTC aria (same port location, same type of case, same pocket) in a construction environment for more than a year with no USB port problems. While it certainly could be caused by lack of protection (pocket lint was my first thought when mine happened) I suspect a bad batch of Ports made it into the assembly line, due to the number of reports I've seen here. My bad one was purchased on launch day - anyone else have one go bad on a significantly more recent purchase?

Mine was doing the same thing, as well as going into "car mode" randomly and freezing up completely. I found a thread that suggested swabbing out the port with rubbing alcohol and a small paint brush. I did that and it cured the problem, but I also bought a case that covers the usb port (otterbox).
This all went down about three weeks ago and it hasn't happened since.

Seems like a common problem from a specific batch of them, so shouldn't be an issue to get a replacement.
Good luck!

Got my first one on black Friday, second one two weeks later, third one, a week or so after that. First two were a 1108, and 1110 builds from what I recall. Not sure what my latest build is, but I got this one at a different best buy (first two from the same best buy) so hopefully if it was a bad batch it won't happen to me with this new one. Knock on wood. This time I got best buy insurance. Seems good, $9.99 a month, no copay for replacement.

same usb problems
I am having some of the same problems. My phone thinks it is always charging, the fully charged notification is almost always up, and my computer cannot recognize the phone. I would send my phone in for a replacement, however the water indicator sticker is red (it got slightly wet).
Does anyone have any idea on what to do. Has anyone else had the rubbing alcohol method work?
I just went through this same issue, but I managed to fix mine on my own. I don't have the phone insurance through ATT, and the overseas warranty support center did everything that they could to deny service. Every time that I would call, they would repeat the steps that we had already been through in troubleshooting. I knew from reading here and other sites that the usb connector, or usb board was my problem. I started out cleaning it with alcohol and that seemed to help a little bit. The ultimate answer was to bend the pins in the middle of the USB connector in the direction of my screen, just a little bit. I have been three months now with no problem whatsoever. I didn't tell ATT that I did this, but I wanted to get a new phone, thinking that this fix would eventually cause the port to break altogether.
This ordeal was extremely frustrating for me, because I have been into phone hacks/flashing roms since the WinMo days. They tried to tell me on one of the calls that they had pushed an update to my phone that would fix it. I promptly told the lady on the phone that she was full of @#$#, as I knew the phone had obviously not been flashed or updated by her text message. She finally backpedaled and admitted that she was lying. It was hard to deal with this conversation without admitting what I knew about these phones. The sad fact is that at this time, my phone wasn't even rooted yet.
In the end, I did get a new, factory battery out of the deal. These idiots thought that a new battery would resolve the issue, even though I told them exactly what the problem was.
I was really pissed about the service I received. I am over an IT helpdesk for a software company. If any of my employees treated our customers like I was treated, they would be looking for work. I expect that they are just doing their jobs as supportbots, just like ATT wants them to.
I decided that if I ended up having to replace the USB board on my own dime, I was going to fix it, root it, unlock it and fleabay the thing. I was going to use the proceeds to pay the early termination fee and say goodbye to ATT forever.
I know that this was longwinded, but I have been holding this in for a while now. I posted this in one of the earlier threads, but then deleted it, thinking that I might need to reference the thread to show ATT that the USB issue was a known problem.
I don't have this issue, but a friend does. What would one do if this happened while their phone was rooted? How would you get back to stock with a dead port?
I had this issue a few weeks ago. About 100 times a day the phone would chime, thinking it had just been plugged in/unplugged. I cleaned out the USB port very well with rubbing alcohol (used a small paintbrush), as well as the internal battery contacts. I also stopped taking the phone in the bathroom while I showered, thinking that perhaps steam from the shower could be causing the problem. I'm not sure if the alcohol or keeping it out of the bathroom did it, but within a day or two the problem stopped, and hasn't repeated itself for 3 weeks or so.

I had the same issue and I manage to get to stock usingh Mobile odin, I went to the DSC or how ever is spell The repair center for att. and the guy took it tried to fix it but was no good, so he gave me a new one. And as the chatter kept going he said they would still take them even if there rooted becouse Samsung can just restore them back to stock much easier than we can. Maybe he was blowing smoke but sounded kinda true.
he said mine hjad some sort of corrosion on the USB port that made it think it was connected that's why it showed that.
I am currently having the same issue. I have an SGH-S959g, which is Straight Talk/Net 10's S II. I'm posting here because my phone is physically identical to the AT&T S II. At the suggestion of multiple forums, I've tried cleaning it out with rubbing alcohol. I even took apart the phone and cleaned the soldered connections to the logic board. There was virtually no corrosion on any of the port. I tried bending the pins slightly forward as well, because that has helped with other phones (Samsung and otherwise). None of this is solving my problem and, unfortunately, my month-to-month service means I have no option of being sent another phone. Any help would be immensely appreciated (especially if it contains a new idea or two to try).
Thanks in advance.

Had same issue, fixed it with ebay item 270993875674. I can't post links so you will have to search. I bought my S2 in fall of 2011, tried a different board it did not work. The Q&A forum led me to this ebay item to fix it. It's an easy fix, takes maybe 15-20 mins if you are being ultra careful.
I recently took apart my galaxy note to replace the power jack. After i put it all together, the screen will not come on. The phone is on and will be recognized my a computer. The capacitive touch lights come on and haptic feedback functions when they are used. But the screen wont come on.
Were do i go from here.
You will likely need to take the device apart again, and re-trace your steps...
Chances are, you have a bad connection to the digitizer screen, and as you know, those connections are "very" small, and are easily damaged or connected improperly.
There really is no other choice, than to inspect the areas you worked on....g

A little more information, I have the device apart right now.
I bought a used Note off of craigslist that had a broken screen and a bad SIM card slot. I transplanted that motherboard into my phone and the screen powers on. But with my motherboard it does not.
What should I look for specifically when inspecting the ribbon connections
That they are connected completely.
rangercaptain said:

Checked,
Phone reassembled completely, still nothing on screen.
Now what.
UPDATE: Motherboard wont power either screen. The bad motherboard will power both.
What is the defect, on the board that powers both screens ?
It's beginning to sound as if you now have two bad mother boards ?
Or at least, a partially working board.
Either way, the device is still broken....ouch
It may come down to taking the device for repair, or trying to find yet another board.
At this point, getting a complete and working device may be in order, as risking more time and money on devices for parts, isn't working out ..
I'm sorry, I don't have any further advice for you at this point ....g
First, you need to differentiate what you mean by "bad" motherboard, cuz it sounds like both motherboards are "bad" in some way.
Your first motherboard is not powering screen, but everything else works. Correct?
Your second motherboard, bought online with bad SIM slot, powers screen, but cannot be used with the bad SIM slot. Correct?
It sounds like your first MB has issues for screen, which is obvious, because the screen works with the second MB.
Then, you may try to replace the SIM slot on the second MB. I think figuring out the problem with the first MB will be exponentially harder, let alone fixing it.
Or, just sell EVERYTHING you have and pony up some cash and buy a working phone, instead of trying to fix this thing. Since your MB is recognized by PC, you can still save all your data.
Agreed ..g

Yes, I apologize. Let me clarify.
Motherboard #1: Does not power screen, but works fine otherwise.
Motherboard #2: Will not read SIM or microSD cards, but powers screens just fine.
I looked into what replacing the SIM and microSD system on the motherboard. Its very difficult.
On the sell EVERYTHING front. I recently sold a set of Rims I had for my car. By some miracle, I was eligible for an upgrade with AT&T. Galaxy Note II ordered.
But, if I can get a spare phone working. Id still like to fix this one.
In my opinion ....
Dump them as parts devices ....
In another few months, these devices will be selling cheap ....imho
Note 3 is already being developed, and the 1 will be rolling off the back end by August/September 2013.
I saw one for sale in Utah today for $125.00
So it's already begun ....IMHO ....g

Hello all
This is my first post here so let's hope I do everything correctly here
I have a Sony xperia Live with walkman (wt19i) which I dropped unfortunately and decided to replace it after a while because I was annoyed by all the cracks and was up for an experiment.
After a long search, I came up with this:
amazon.com/gp/product/B006MQFFZQ/ref=cm_cr_ryp_prd_ttl_hst_1
I also posted my findings there already to help other people who might want or need to replace their digitizer as well.
But the bottomline is that the screen sometimes just locks up or starts acting weird... then I have to lock/unlock and it is all OK again for a while.
At least once a day I have to take out the battery because the trick I explained above doesn't work anymore at all.
The hardware buttons do.
I have the idea that when I keep playing a game for too long; it locks up faster, so the device warms up.
I guess I already know the answer but I was hoping that someone had any idea's how to fix this as I already did the installment of the digitizer over again without much luck.
Thnx in advance!

Hello! I was facing the same trouble with my Xperia Mini Pro which unfortunately expired yesterday.
I had to replace the digitizer+Lcd whichI bought off eBay (money wasted). One thing that you should see is what you use for sticking the screen unit to the phone (I am assuming that it was stuch to the phone using some kind of adhesive as this is the case in Xperias and maybe others too).
When I replaced mine, it was working fine until I used (very carefully) quick drying adhesive on the edges. My guess is that some of that got between the digitizer and the lcd by seeping in because after that, I started to experience the SAME issues as you. For me sometimes, rebooting would be the only thing to make it work again.
I hope it gets fixed for you soon. It only went downhill for me though

Hi there and thx for your reply.
Sorry to hear that you are experiencing the same kind of problems.
Unfortunately I've had this problem from the beginning, when I unpacked it, I could already see that it wasn't an original part under bright light.
I've used 1mm Wide Double Sided Layer Adhesive Sticky Tape Sticker for Mobile Phone, which I also bought on Amazon, despite of how hard it was to apply, it the replacement went fine with it.
The second time I took apart my phone just to see if I did connect everything well, I also re-applied the sticky dual sided tape.
But that did't really help.
But so i've someone has some knowledge or knows some tricks I can experiment with, that would be nice
I read something about heating up the phone like this thread here for example: http://forum.xda-developers.com/showthread.php?t=1041943
I'm willing to try that if there is really no other option
But as I said, it's probably just a badly constructed digitizer I got from China.

Yes, I've read that here before, but my mind cannot really get around the why... ?
It wasn't like they were stuck together that I could damage the other when replacing it.
Neither were the parts sold together.
The screen still works and the digitizer as well, it's not like it's not working at all.
The digitizer just stops working after a while and when I lock/unlock again it works fine again.
As far as I remember I also had do connect the digitizer to the mainboard, not the display itself.
It isn't an easy issue, that's for sure
Hello.
So to make a veeeery long story short, the phone leaked water in a lake at about 0.5 meters depth after a minute or two with flaps definitely closed (checked 5-10 times before submersion). The screen then flickered and died.
Phone gets sent away to a service center, tested and results unsurprisingly say its watertight so must be user fault. Sony and service provider refuse to help me in any way to fix the broken phone, so basically they say i have to pay it as normal (it was 4 weeks old at time of damage).
I received the phone back after countless phone calls to sony and service provider trying to get them to take responsibility, especially sony, but to no avail.
So now im trying to fix it myself. I took the phone apart, and the screen connector at the bottom was fried as expected. I bought a new screen and flex connector cable but still my screen wont show. The touchscreen works perfect, and so does the phone. When i connect it to my tv via MHL it works flawlessly. Every function including the new touchscreen works perfect, just that the screen is black on the device.
Am i missing something?? I really want to get this working so i can say IN YOUR FACE to this stupid company SONY. Im thinking the only thing it could be now is some faulty component on the mainboard regarding screen output, seems strange though that everything works perfect via MHL, especially the touchscreen.
Anybody have any ideas? Would be greatly appreciated if anyone can share similar experiences!
Cheers, Vincent from Sweden.

Hello.
The phone has booted ever since it got water damaged, even with the bad screen. Yes the touch panel works perfect but no display, and i can see and use everything on the phonebon my tv via mhl cable. I even updated firmware whilst using mhl to see if it would help but still no picture on the device.
I have replaced the touch screen and the flex ribbon cable that connects screen to mainboard. I have also removed mainboard and cleaned it with 95% alcohol incase some water or dirt causing a short circuit somewhere.
The mainboard looks fine, and everything works apart from the visual screen. Nothing is overheating. Im really baffled as to what could be wrong, but it surely must be something on the mainboard?

I got same issue on Galaxy S4 but that wasn't water proof so this type of damage was normal for it.
have u tried ur display on another board?
- as Sony said it was user fault... after phone get wet have u tried to dry it with heat?
+ as i read the warranty agreements when u open phone by urself or others (non official center) it will void the warranty.
anyway If ur display not working with another board so thr is problem in display panel and not anything on board.
Please Inform me if u got any info or result of this damage
Thanks

Yes the phone is thoroughly dried out. I only opened the phone after i had received it back from sony service. They said it wasnt covered by warranty because it was water damaged and was caused by the user (even though both water indicators behind the 2 flaps are still white and not been exposed to water), and they said that they never repair water damaged phones.
Thats why i decided to open it and try to fix it myself, i had nothing (more) to lose!
I havent tried the new display on another board, thats exactly what i want to do but cant get hold of a new board. I've even been taking apart previous smartphones to see if the display can be connected to it somehow just so i can confirm it works. But the probability is that it does work, as the first "broken" screen worked in the same way as this one, touchscreen fine but no display. Thats why i changed the flex cable also, i thought it must be that when the mainboard seems to be doing everything else perfectly.
Does the problem have to be in one of those 3 components? Screen, flex cable, mainboard, or have i missed something?
Thanks

Yes, it should be those factors. From what you have stated, its most probably the connector on the main board. Before you make more purchases, try to take it to a shop and ask them to test the screen on another phone, so you can see if its the screen or not. It MIGHT be a faulty flex cable that you just purchased, hopefully, since its the cheaper solution. I actually bought one in ebay that was water damaged, changed the screen, middle frame and flex cable, and have a brand new refurbished Z2, good for me the main board was intact. I would take the board out, wash it with 95% alcohol again with a soft toothbrush to brush impurities off the connector piece. Then spray it a little with electrical spray and leave it in rice to thoroughly dry out overnight and try all the connections again. Look through the main board with a magnifying glass and see if anything obvious burned out, the smallest connection can cause problems.
If all fails, then take it to a shop to test the screen or the main board, hopefully they are friendly enough to do it.
Good luck buddy. :good:

Sounds like good advice elbello
Good to know that you have managed to fix a water damaged Z2 using the same mainboard, hopefully i can have the same luck.
So you think it could be the flex cable? Are they known to break easily?
I have already cleaned the board twice with alcohol, maybe using electrical spray might help, and i will check it with a magnifying glass aswell.
Hopefully i can find a shop that will test the screen for me, but this is Sweden, the place where no favours are done, and where everything has to be sent away and fixed by professionals!
Thanks for the replys guys
I have just checked the whole mainboard with a magnifier, and found no oxidation anywhere. I found quite a bit of dirt in some places, and i have once again cleaned the screen connector with 95% alcohol and also the other side of the board behind the screen connector. I dont have any electrical spray at this time so cant test with that.
Another thing i have realised is that there is visual damage to two contact points that are located at the bottom of the phone, very close to where the flex cable connects to the lcd screen. What are these two contacts for, and could they be causing the problem? I will attach an image of them.
Thanks.

From that picture, I dont think that affects the screen at all. Bad thing is you cant try the two pieces you bought with another board so you can narrow the problem down.
I doubt the electrical spray will make wonders, it just good to clean dirt and make the contacts react better after oxidation, but if you state they are clean...
Think your only options is to consider it a loss, sell it in ebay for parts and stuff, or try getting a new flex and see if it was that, but if it wasnt, its like throwing money away. I would say the same for the screen, but those go for $100+ easily.

Yea i was thinking about selling it for parts, but its not really worth much without a working mainboard. I will probably just keep it and wait till i can get hold of a new board. How much do you think a new board would cost? I cant find one anywhere at the moment when searching on ebay/google.
Wish i had access to a working board for testing
Hello,
I have the same problem ... black screen on the tv works perfectly, xperia z2 also drowned after 10 seconds under water .... someone back to life solved the screen, that you have replaced?
best regard.

Hello,
I'm now in the exact same position.
Water damaged, Touchscreen is still working I can enter recovery any press stuff but no display only shows black.
Had my screen replaced in a shop here but same problem prevails.
They told me to replace Mainboard 3500 THB.
But they didnt have one right then.
He could fix it?

he could you solve your problem? It happens to me the same with a z2 . I board bought new eh and the problem persists . you could help me?
Thinking of buying a used z2 with intermittent touchscreen issues. It works but seems to be intermittent it either takes multiple taps to work or it goes mad like your pressing the keys could this be down to water damage or possibly just a software issue and need re-flashing a ftf by clean install it's a totally stock z2 in mint condition for £50

It's probably hardware problem. Trust me, ghost touches make people go crazy,so don't buy it.

Ghost touches are a digitizer problem right?
You can buy a new one for about 30-50$

Probably yes, but replacing it isn't so easy these days.
