Hello!
The problem appeared suddenly. I had been using Ultimate HD ROM for over a year with no problems. Few days ago when sliding out the keyboard, the screen went blank. Backlight was on, keylights were on. Typing on that small phone without HW keyboard is absolute rubbish.
Some moment, it just got into bootloop after it crashed while I stopped bluetooth tethering. Flashed the phone with Flashtool, with .587 stock firmware. Issue remained. Opened PC Companion and proceeded to "repair phone". It installed .587 stock firmware again (i guess it's that factory restore thingy). Result? Nothing!
Rooted the phone, installed recovery and Revolution HD ROM. Nothing. Tried to install that "keyboard zip file" while in recovery. Install succeeded, but the problem still remained!
Here is the video of phone and the issue itself:
htt***ps://ww**w.youtube.com/watch?v=mArrpkR1vR4&feature=youtu.be (remove the *** from the link)
Is it a firmware issue or hardware? What could be done?

From your description it seems like the flex ribbon acting up. Swap with a new flex and you're good to go

Thanks for your reply!
I used a plastic card to put some pressure on that flex. Nothing happened. If flex ribbon would be damaged, why does the screen work in "closed" form? Or it's just matter of time when the whole screen will stop functioning?
eBay shows price 10£ for the flex, with shipping. I would like to be sure it's the flex ribbon thats's causing the issues. As it seems to me, replacing the flex isn't really a nice job either.

Yes it's just a matter of time until the whole phone(yes, phone) stop functioning. I had the same symptom, it was working for a few weeks then bam. I tried to reboot but it doesn't boot, not even recovery. Ordered a new flex (~$15, free shipping), replace the old one, then it comes back to life.
Your mileage may vary, but it should be similar. Look the other thread, they already discussed this there

Okay, now I at least know it is matter of time when it dies. Phone itself is 2.5 years old and been constantly used. So I guess it's no wonder that the flex is worn out.
Is there any point trying to change the flex cable on my own? By seeing Youtube tutorials about disassembly, it seems there's too much hassle and it might be better to order whole frame with flex already. I am concerned about the transportation also. If the flex is already installed to frame, then it might actually work.
Or it would be easier to drop it to nearest service center?

If you have trusted place I think it's better to drop to nearest service center. It took myself(inexperienced) a few hours to separate the screen assembly........ AND the proximity sensor is broken. Flex ribbon got no warranty from the place I bought it [emoji23]
The flex ribbon consists of front cam, notification LED, proximity and light sensor.
Test them right away before leaving service center to claim for warranty.

Thank you!
I will probably drop it to nearest service center. I will not try to change the flex on my own. Too much hassle with glue.
Thanks for pointing out critical spots in changing the flex.
I guess the topic can be marked, as solved. Will use the phone till it dies and then going to drop it to nearest service center.

well i have an odd problem, one one section of my screen doesn't pick up touches, only the area where the "C" is on the keyboard...its annoying due to thats where the OK buttons are...
i can still navigate sense i can use the track ball..
anyone else have this issue, or something similar?
Try wiping back to factory if stock or reflash the rom if rooted?
I had a weird issue with the touch screen on condemned 18.3 where on the lockscreen trying to drawdown the slider and then draw the pattern, it would freak out and glitch and not follow my finger at all and take several tries to get the pattern correct.
I then wiped and flashed the latest 4.0 GSB and haven't had any issues since.
That's not quite a touch screen failure as yours is, but I thought it would help as an example as something gone wrong and how I was able to remedy it.
i've tried flashing a few different roms, went from cs18.3 to a 2.1 sense rom, back to the latest gsb. it appears its must be a problem with the digitizer...
really sucks, i have to wait to april to upgrade this phone...
might be on craigslist looking for a cheap droid 1...
Ah man, that's unfortunate. Probably wouldn't be worth it to try to replace the screen/digitizer either. Yeah, that's probably your best bet, looking to get another phone. That's how I got my Eris, from craigslist. Great way to go about doing so.
Good luck to ya.
I actually have the same problem and something leads me to believe that an update is causing this. I had it bad a few weeks ago (can't press C, V or X - though I can swipe to the keys sometimes) and then I got a few market updates for Handcent, SuperUser, and something else which then cleared it up for a few days. Then I got more updates and it's back to the failing keyboard!
I really don't know how to pin point it and I haven't done any resetting or testing yet, but I have like gut feeling something is wrong with the software, not the touchscreen since someone else is having this problem.
Mine has been failing little by little. Im now down to the top right corner, bottom left, and bottom middle not responding. It hard to even get the apps drawer to open. It all started with the letter C with me too. Just gets worse.
****, my whole qwerty row doesn't work, neither does the trackball. Upgraded to a SGS2, but I still tinker with the ol' eris.
mine moved, it started working fine for a few days, then just a smaller section to the left of C doesn't work, only really effects when i have an "OK" to press...but track ball still works and typing is so much easier now.
my wife thinks its because i dropped my phone that it started working again
I know this thread is a couple of months old, but...
There's an area on mine at the top right below the notification pull-down that appears to be dead. I'm thinking it's because I've dropped it about 10 times, but nothing looks wrong with the screen otherwise. I've thought about buying a replacement screen for about 15 bucks, but I'll be able to upgrade at the end of March, so I'm really just thinking about holding off (though if the new screen/digitizer worked, it'd make for a good mp3 player with the wifi script).
Digitizer is going bad. Same exact problem happened to mine. I replaced it myself and it works perfect. I found how to videos on youtube and bought a digitizer for about $37 online. Only took a half hour to tear apart and replace. On the difficulty level, I'd give it a 6 or 7.

YMMV.
Someone gave me an Eris that had digitizer problems along the lower left side of the screen (in portrait orientation). I bought a replacement digitizer ($22 iirc), installed it, and it worked perfectly - for about the first 30 minutes. Then, the problem re-appeared in exactly the same location with the new digitizer.
Same behavior for a variety of stock or developer ROMs, so highly doubtful that it was a "software problem". Very very odd - the chip that does the capacitive sensing is on the flex circuit attached to the digitizer, so it gets replaced when you replace the digitizer; I suppose that the signals that come off the mini-connector between the digitizer assembly and the phone's mobo are only power, ground, and I2C signals.
But there you go; taken all those observations together, I'd suspect that I had a problem on the phone's motherboard which was thermally dependent.
Despite my (negative) experience, the odds are still in favor that a digitizer replacement will fix the problem; but there is an outside chance that it won't.
just sayin',

So, after cracking my digitizer a few wks ago- I decided to drop the 65 bucks to have my digitizer professionally replaced. This is the first time I've ever had one replaced. Last few days I've noticed things like random screen unresponsiveness and capacative buttons not working until phone is put to sleep and woke back up. Do these seem like side effects of this being a botched repair job? At first I thought it was the rom I was on, but I switched back to sense, and now it's still doing it. Totally random, sometimes I can go hours without it screwing up.

sounds like its not getting a good enough ground and hence the spottyness. i would take it back to who did it for you and have them fix it.

I had similar issues on my Asus Transformer after I took it apart and put it back together. It ended up being simple: the ribbon cable going from the digitizer to the main board was seated slightly crooked, causing it to occasionally malfunction from either poor contact or shorting two neighboring pins every now and then. Re-seating the ribbon cable into the connector seemed to fix the issue.
It seems likely that whatever is causing your issue would be a similar connection problem between the digitizer and the board. It is also possible that the replacement digitizer is simply defective. Either way, sounds like you need to talk to the company that replaced it for you and see what they can do to fix it.

Thanks for the replies. I talked to them, and get this.. They're ordering me another rezound.. I guess it's such a PITA for him to take back apart, that he'd rather just eat the charge of a new phone (at least it better f'ing be new!).. Supposed to be in on weds.. Didn't I read somewhere that they were out of rezounds?

that was a temp thing for VZW returns. they have a bunch now. lol
So now that I know I'm going to have a new rezound tomorrow- I'm re-doing my homework on getting it unlocked/s-off.. The jbear instructions have d/l's for ics leak fw, do I really have to be on that leak, or does it work if I immediately ruu to the latest 4.03.605.2 and install a custom rom w/ root?
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.

But digitizer and screen are one unit and not intended to be separated. Maybe that's the problem!

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,
My friend has problems with her SGS3. It's about 1 year old and it started restarting and turning off itself. Sometimes it's on a keypress, sometimes while charging and something it just went off without touching anything. She sent it to repair and they said that there is some damage on motherboard from water (but it was never wet so it's weird) and it's glass is broken (it felt on the floor and broke a few days after buying), but the screen and touch digitizer work fine.
Since the repair is more expensive than new device, she wants to check if there is some software problems before giving it to someone who can try to fix it. The phone is not rooted, so is there any easy way to check its logs (some app or something)? Is it even possible without rooting?
In case of hardware problems, what should she do now? If the mainboard is broken and the glass is broken too, it's almost impossible to sell it for parts because only battery and soem minor parts are usable. Is it worth repairing the motherboard?

Isn't that the USB port? Looks like it's already fried. From the looks of it, the service center is right it's a hardware problem and for them to say that the motherboard is broken probably means other components are also fried. In my opinion it's better to buy a new phone as a repairing it outside warranty is much more costly than buying of a new phone.

Yes, it looks like USB port. Maybe something is fried, but the phone works so all chips and electronics must be okay. They said that there is corrosion on the motherboard. The phone was never wet but it can be due to condensation or humidity. I have a friend who told me that he can fix it if there is only little corrosion, but before trying, I would like to take a look on logs if there is some software problems. Another friend told me to wipe and flash original kernel and ROM from fresh, but I don't think that this is a smart move since the port could be broken and we could brick the device if it lose connection during flashing.

I see... so the phone still works. That type of damage is probabaly because of humidity like what you suspect. In my opinion further use of the phone with an existing hardware problem can lead to a more bigger problem so no logs can be of help here. That fried usb port can also hinder on flashing a new rom like what you said as it may fail during the flash that can corrupt the internal memory of the phone. I think your friend's options are only two. Have it repaired or just buy a new one.
Yes it works but it's barely usable. It's blocking (getting stuck) and restarting all the time. Do you know maybe how to read those logs? I never used logs so I don't know. I was googling about it but I didn't understand it well. It seems that the phone has to be rooted.
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 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.

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?

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.
