Hello, I was having my Mobile phone in my pocket (SK17i). I took it out and suddenly it touch screen stopped working.
I was having MIUI 3 on my mobile with Extended Xperia Kernel.
I just want to know, what has occured, I mean if it is Software problem, or a hardware problem as there is no damage to mobile screen, not a scratch. The touch button, i.e. back button and menu button work properly, just the touchscreen is not responding.
I have tried to change the ROM to original one. Changed the Kernel too. Still no response.
Kindly help me. Please
Sorry mate, but all indicates hardware malfunction.
I got a similar problem with a different phone wen it spilled some cafe on it (very little).
I opened, cleaned and everything worked except touchscreen.
Could it be some humidity on the phone?
(hope you didn't pissed your pants )
Anyway, for this phone you can order a new LCD + Touch from the ebay and assemble yourself with a tutorial on FixIt (google it).
If it still has warranty just send it back

Hi guys,
I bought a second hand mini pro, and flashed (rooted, unlocked bootloader)it with the help of one of the several guides. with Simplexity and MiniCM7
It seemed to work fine at first, but now something odd happens.
I can only turn the device on (working) when I keep the keyboard slided out. When I start up with it slided in, The screen is turned on but no image appears: It stays black.
When it is turned on (slided out) I can use the phone normally. But when I slide it back in, the screen is frozen and won't react to touches.
Putting the phone in and out of standby (slided out) will have two possible outcomes: Either its usable as normal. Or it simply won't come out of standby at all. The phone seems to react (sounds) to pressing the buttons on the keyboard though.
I used Seus and manual methods to reflash to stock, try other kernels, but the problems remain.
I think it's the hardware that's failing but maybe this can be caused by the flashing as well?
Are there any methods to rule out one or the other?

I'm responding to the thread's title : It's a hardware failure.Brick means you can't even power it on/flash mode.If I helped click the "Thanks" button.Also,try using nAa-11 my and x10man's ROM called XMP Rom and tell us if you still have this problem.I understand that you posted this here (If you post it in questions section almost no one will respond )so I won't tell about that.
(Oh, my bad. Mods feel free to move my thread)
I was afraid of that. I'll try your ROM as well, but I'm afraid its the hardware too.
Thankfully I only paid 30 euros for it
I think the flex cable is gone bad, i have the same problem here. My mobile doesnt respond to any touches. First it happened only when i would slide the keyboard. But now its dead as a whole

The XMP rom didn't fix it, so I guess you're right. Would a flex cable (those are the flat orange ones right?) be expensive?

This is the cable we are having a problem with, i have given my mobile for replacing this stuff as i couldnt get this locally. This board houses the LCD and the digitizer and the buttons connect to this. The black cable goes to the motherboard. Its pretty simple to take apart the phone, but take care while doing so. Another thing its that, when you are opening the display panel, its better to use a guitar pick instead of a screwdriver and open it at the latches, that would avoid damage to the outer plastics.

Hi boys,
yeasterday I changed digitizer on my Xperia PRO mk16i, which was broken, but still fully functional.
Now I have problem with this new - in the middle of LCD it´s don´t read my touchs. In the top and bottom of LCD is situation better - it is almost functional.
I found some recalibration functions, but it´s no possible via standard phone menu. So I tested change firmware with Flash tool. I tested A 2.3.4 and 4.0, but everything is bad - I cannot found any calibration function. (When I bought my phone, first thing which I must do was calibration).
Please, can you help me? What I must need for run calibration process?
Many thanks,
Petr
Wow, I've never heard about touch calibration on capacitive devices. I'm pretty sure your new digitizer is defective. Happens to the best of us hehe.
I have similar problem with this guy. Middle of the screen doesn't read my touch, I'm using mini pro. My case I hold my phone with wet hands, then the day after, it happens. Flashed to stock didn't help. It seems your digitizer is defective as said. Take the phone to where you changed the digitizer and ask for warranty.

Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
Hey Guys,
I am having a big problem with my device. The touch is not working. I have been flashing various roms on my phone and after playing with many roms, i finally flashed stock rom into my phone and flashed a stock ics based rom. Everything was working fine until one day my touch was not working well. I switched off the phone and turned it on and the touch was right back on. Again, things were smooth until this issue happened quite frequently. The problem was solved after turning off the phone and powering it off. After some time, the problem again started to come. At this point, the touch was not working COMPLETELY.
I was scared and immedaitly flashed the stock rom. During the initial boot, everything was working fine. But, when i locked the screen and tried to use the phone after some time, the same problem occured again.
So friends, my question is, Is this a software related problem or a hardware related problem. If this is a h/w related problem, is there any point in touch working during some time and not working later? ( Now, touch stopeed working completely). Will any tutorial on this forum about bricked touchscreen (after flashing wrong rom, which i am sure i didn't) will help me solve this problem?
I am awaiting for your valued input as this is the phone that i use for all my communication needs.
Kindly help me
Thanks
Well, if stock didn't solve it, there's a chance it's a hw issue. If you look closely, "touchscreen brick" guides are meant for the mini and the lww (touch digitizer separated from display), not the mini pro (touch digitizer and display as one assembly).
And yes, there are situations where your touch digitizer might cease to function for a few seconds then respond after a while, and sometimes it stops working completely after the next reboot (or forever). It happened to me with a deffective replacement part.

Thanks for your reply.......
I guess it is indeed an hardware issue. My phone used to reboot when i slide my keyboard out fast. The screen gets dimmed out and the phone immediatly restarts. Last few days before the problem worsened it was overheating also.
Can you suggest me which hardware part i should change to rectify the touch issue? Awaiting for your reply
Thanks a lot
Ok your problem seems to be worse than expected. A faulty touchscreen shouldn't cause sudden reboots. I'd say it's a flex ribbon issue.
Try to get a replacement flex ribbon and test it extensively before installing it on your phone. Replacing the flex might be enough to solve all of your problems. If any of the problems persist with a new flex, you'll need a new screen assembly (quite expensive at 35~50 bucks).
I have an Xperia Ray Running on LX CM13.1.
One day capacitive touch buttons started showing ghost touch continuously. I then restarted and capacitive buttons stopped working.
I then activated onscreen buttons and some days later they started showing ghost touch continuously. I then restarted device and that part of screen also stopped working.
With in a fews days ghot touch spreaded up and finally bottom half part of touchscreen stopped working.
I tried hard formatting and even I flashed stock firmware but didnt fix the issue.
As I know it is a hardware issue, Will I have to replace my entire display?
Display part is working properly but touch is irresponsive.
Thanks
It seems like the Ray has the display stuck to the glass/digitizer with LOCA adhesive, so yeah, you need to replace the complete assembly, unless you find some service center where... Nah it's not worth the hastle lol.
I replaced my Mini Pro's display a bunch of times. It's sad to see a perfectly working LCD display go just because of a broken glass/digitizer.
