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.

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
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).
Hey guys, a friend of mine give me his moto e cause he had soft bricked it. Reading through the forum I could reinstall the firmware (4.4.4 latam) and now it's working fine, but there are 5 spot in a vertical line that doesn't register my touches, these spots are aligned in the middle of the screen, one is at the y position of the keyboard, and the others are separated 1cm each other (1 is under the y and the other 3 are above). Could this be a software related problem or I just have to replace the touchscreen? (I've tried factory reset two times but I've not reflashed the firm again) thanks in advance and sorry about my English.
First take a try with Screen tester app die playstore, and change rom once, if didn't helped, you can replace screen assembly at low cost on local markets.
Well, i've reflashed the stock 4.4.4 firmware and it's still the same, i guess i'll have to replace the touchscreen. I dont know how the touchscreen works in this phone but it's a little strange that certain isolated areas in the middle of the screen doesnt work..

I had the exact same problem. I had 4 such huge spots on the left side of the screen where touch didn't work. ROM reflashes don't help. Yeah it's really strange. First I thought it might be cuz of water spilled over the screen but later on found out that the display assembly is completely sealed and water can't get in. Yeah it's really strange how display suddenly stopped working that way..even touches of local phones don't get magically spoiled like this, dunno what's up with moto. I got it replaced from local market for 1300. I would say the quality of the display, touch, brightness, contrast, everything is same as that of the original display. The only thing I suspect is that the glass is not gorilla I guess.

I have a sony Xperia z2. Bought it a year ago, everything worked fine for 11 months. One day i was using my phone and suddenly the screen went haywire. On further inquiring i realized it suffers from ghost toughes. I enabled the show touches option to give me the exact idea where the ghost touches appear on screen. There's something strange about it, only 2 ghost touches appear on the top right side of the screen, BUT WHEN I SWITCH OFF MY SCREEN AND SWITCH IT BACK ON THE SCREEN BECOMES RESPONSIVE FOR 5-6 SECONDS. Then ghost touches appear again. I have TRIED everything, formated, restarted, changed screen guard, cleaned the screen, changed the charger, did a software repair procedure suggested by sony. I really really really need help, I'd really appreciate it if someone tells me how to fix this issu. Thank you.
