[Q] Touchscreen not responding - XPERIA X10 Q&A, Help & Troubleshooting

Hi folks
Just inherited a very worn out one year old Xperia X10 from my son. Been trying to resurrect it.
About 2 or 3 months ago the touchscreen started to become non-responsive occasionally. Admittedly, I didn't look at it for him at the time. Then he dropped it down the loo (think - hope! - there was only water in it at the time). We dried it out in the hotpress and it worked ok but still with intermittent touchscreen not working.
He got a Blackberry from Santa, so a couple of weeks ago I inherited the Xperia. The screen was cracked in several places and totally non-responsive. Rather than chuck it in the bin, I thought I'd try and fix it up. So I bought a new screen on ebay and the other night I dismantled it and fitted the new screen. Touchscreen is still totally non-responsive. There was a slight rust on the perforated metal plate at the back of the screen which I carefully cleaned with WD40. All the connections and circuits look ok. I've updated it successfully on both PC Companion and SEUS.. I've also tried flashing using instructions from this forum but cannot get it right (most flashtool symbols greyed out). I have a feeling that it's a simple problem but just can't get there. The screen display is fine, I can get the camera and the keyboard up using the buttons. But damned if I can get the touchscreen to work. I feel the problem harks back to when the screen was intermittent - it still worked after the water/screenbreak, but not that well.
Anybody got any ideas or should I bin it? (Can't seem to get any worthwhile advice on the WWW - happened upon this forum while searching and thought - "This is my MAN". (One suggestion I saw on the web was to try a new battery - can't see how this would make a difference, present battery working fine. Also, I wondered if the proximity sensor could be on all the time?)

Erratic touch screen? Please help!

I have a T-Mobile Pocket Phone Edition,
It's had a rough life but as kept going for over 3 years now.
For the last year I would have to realign the screen 2 or 3
times a week but over the last few months it keeps getting worse.
Sometimes the screen won't respond to anything anywhere,
then after I tap it a few times boom works fine.
Sometimes I'll tap on the “Ok” and the “Start menu” will activate.
Sometimes drawing a line up the center of the screen will end up
shooting all over the screen.
And sometime it will work perfectly!
I thought the problems were to erratic to be hardware so
I hard set after awhile it started again,
So I hard set and installed a different ROM after a coupe hours
the problem was back.
Also sometimes the align program will get stuck in a
loop that doesn't end.
I've searched but can't find an answer? Anyone have an idea?
I've already taken it a part once but couldn't see how to get
any further after I toke the back panel off? Please help!
WOW nobody? So no one was heard of this problem before?
Can anyone direct me to directions on taking apart the Wallaby?
Thanks <><
It's a problem with touch screen. You should check (and fix) it.
Maybe it is necessary to press well screen to the motherboard. (Sorry my english).
Ok, Can you tell me where that connection is?
Thanks
Toke everything apart, found the connection, cleaned everything (w/ screen wipe)
put it all back together. Still have the touch problem and now the backlight won't work!
I've found if I press the unit in my hand the touch panel works right,
I don't think it's a lose connection to the main board so I think it must be
one on the main board.
If anybody thinks they want it for parts let me know! :?

[Q] Oh my poor Aria! (Screen Replacement issues. A little help please?)

Well I did it... Broke the screen a couple of weekends ago. Ordered and received a new one. (No problem and not too bad price-wise) Then I ordered the correct screwdriver. That came in yesterday and I followed a couple of tutorials online to take the thing apart. Not too bad despite the teeny-tiny parts. I got it back together and lo-it worked! Actually it took a couple of tries and I reflashed it but then it booted right up. All the apps seemed responsive and life was good once again...
Until I tried to make a call. Then the screen went dark and it appeared that the phone froze up. Called myself from the house phone and discovered that the Aria was dialing, connecting, and sending voice but that I couldn't hear anything on the Aria.
Disassembled, re-set the earpiece, reassembled, called myself again, and I could hear. The screen came on and stayed on, but the touchscreen would not function.
Disassembled, checked all the connections, and reassembled again. The phone appears to work correctly in all aspects until I try to make or receive calls. At that point the screen shuts down and the only way to disconnect a call (or get the screen back) is to pull the battery and reboot.
I tried reflashing the ROM and that didn't work. I'm afraid the transceiver is shorting the screen out somehow but have reached the limits of my expertise.
Any suggestions?
Thanks,
Jerry
I have never had to replace my digitizer so only speaking from what i have read but it sounds like the very small rubber piece that covers the proximity sensor. I have read that if missing or not placed correctly people have had the same problem as you. Just my thoughts
I've replaced my digitizer and I have had the exact same problem. E.Cardo is correct, it is the small rubber piece on the proximity sensor not positioned correctly or not present at all.
Thanks to both of you. The proximity sensor is supposed to be right behind the ATT logo, correct?
I can't wait to get home and try this. I really don't like the backup Cliq Xt... I'll post once I've messed with it.

It's hard to see them exactly so I took a picture to show exactly where they are:

It's actually just above the & in the at&t logo, although if you have a replacement digitizer, it might not have the at&t logo on it. If you have trouble seeing it, try looking at it in the sunlight.
To add to what drumist said there as small black rubber piece that goes around the proximity sensor that prevents light seepage and allot of people discard it by mistake when disassembling the phone.

Why did you have to reflash? The new screen didn't worked?.
My aria's screen is broken too. I boutgh a new one but It doesn't work. Do you resolve this reflashing? (that's mean applying the new rom version from ATT)
Thanks for your response.

The screen or digitizer are hardware they should have nothing to do with the rom. The op only tried flashing the phone to illuminate it is a possible source of the problem. It sounds like you did not install the new screen or digitizer correctly you may need to disassemble and make sure everything is connected correctly and securely. Flashing your phone will most likely not correct your problem.

Maybe, just maybe, there are new drivers for the touchscreen included in the rom. I am using cyanogen 7.0.3 without problems, and it works nice with the old screen.
Or the new screen is defective.
I am pretty sure I installed correctly the new screen. Of course the old one is working fine right now.
I requested a new screen so I will wait...
Thanks again.

[Q] Rare Touchscreen Issue: Faulty Horizontal Line

Hey guys,
My screen woes just won't go away. I dropped my phone a few weeks back and cracked the screen. Ordered a new one from eBay (Item number: 260818538062) with the faceplate and everything. Had it installed but then started noticing that SWYPE wasn't working as well because my words would start breaking midway. Installed Yet Another Multi Touch Test and when trying to paint realized that there is a very evident line on my screen that isn't working as well. That was one continuous movement of slow up and down jestures but as you can see, the touch sensitivity is much weaker as well as the screen sensing a second touch at some point.
What can I do? I will gladly take the thing apart and clean the connectors.. if that will help. But somehow am inclined to believe that the issue lies with the screen. Is there a software recalibration fix that exists perhaps? Anyone experienced the same thing and walked away with a working solution?
Please help and thank you in advance.
(EDIT) I've added a second attachment where I started going around the outer edges working my way in, there's definitely one faulty line in my screen!
(EDIT2) Found a native Android touchscreen test (white and green) thanks to a member named BryanNL in a different post. Basically had to dial *#0*# and chose it from a menu. This test claimed that I passed but you can see that it is not made to tackle an issue like mine.
Bumping.. Anyone please.

[Q] [Xperia U] My touchscreen seems broken / acts very strange

I have got a (most likely) hardware related issue with the touchscreen of my Xperia U.
Some parts of the screen are not or barely responsive, which is very annoying when typing. I have to tap some letters twice before they actually work. (It's especially around the 'i', 'n' and 'e' when I have my keyboard open by the way.)
I was running stock Android GB and I'm now running stock Android ICS, after I updated my phone the problem was still there which is why I assume it's hardware related. There does seem to be a slight improvement though, but that's probably because ICS feels a bit faster (so far).
Like five minutes ago I noticed something very strange, when I put my finger near the 'N' on the keyboard, but not touching the screen itself, it kept touching it like 10 times a second, sometimes holding the touch so it would result in a ';', but that's not really relevant I guess. It stopped doing that after I turned the screen off and on again by the way.
Now I've downloaded a drawing app on my phone, to see if the phone would skip the parts that were responding bad, but that wasn't the case.
(I would send a picture, but I'm not allowed to send outside links as I'm a new user, sorry. )
There is a chance that this problem is caused by a kind of overpowered charger I had been using last summer, because when I plugged that in, the phone started doing the same, only waay worse. I haven't used it for almost 3 months though, and the problem occurred just a few days ago, which is pretty weird.
I can probably get a replacement touch screen for free because my brother had this phone too and he bought a new phone because the glass of his screen broke.
But I hope I don't have to use that, haha :angel:
Is there any solution to this without taking it to a service center or replacing it?
Thanks!

Lots of touchsscreen thread in the forum, search and see what they did

Line on keyboard off calibration after screen replacement.

I just got done replacing my broken screen on my LG G3. I replaced the whole front panel and just transfered the guts. Everything checked out fine after replacement until i typed my first text message. row A-L will not goto screen unless I touch nearly inbetween the middle of the row beneath it. q-p work fine as well as z-m. What really has me boggled is that the screen accepts touches there in virtually every other app/drawing. Just the keyboards aren't allowing touch in that specfic row. any suggestion?
Found a few more bad section.. Pulled the back loudspeaker back out and tried reseating the cables and still had same issue. They're sending a replacement for free.
This was my first screen replacement, but not my first time dealing with small ribbon cables. All cameras function fine, hoping it was a defect in screen and not my screen changing abilities.. Any tips for the next one would be appreciated. Would like to have a fully functioning phone again sometime. This is nearly more frustrating than the broken screen.
I am having same Issue

Hey just curious if your issue has been resolved.... I am having same issue, but i took mine to a computer store i have been dealing with for years. about a year ago they started doing cell phone repairs as well. I had them replace my cracked screen on my LG G3 and that same row of text if off for me and there are a few other spots i have noticed are off as well .... very frustrating... Anyway the place I took it to has replaced 3 screens hoping they were getting defective parts.... they just called to tell me I can come get it but they were unable to repair the dead spots without going further into replacing boards or something.... I dont know... It is weird though cause you can get the dead spots to work sometimes by very lightly touching or just touching it in just the right spots like a calibration if off....

A review on G3 LCD's on Amazon reports the same problem "I installed the screen and immediately my wife mentioned that it seemed to have "dead spots" when she was texting / playing games. I noticed it myself when I tried texting myself as a test. Several of the letters on the keyboard just wouldn't register very well. She went into the settings and ran the "motion sensor calibration" test under general settings>gestures. This has resolved the touch screen issues. "
I don't see how that would fix it but I guess it's worth a shot.
