Yesterday, I was just using my phone when the touchscreen suddenly stopped responding in one area. Its a bout a 2m wide strip running across the phone in portrait mode which does not respond. Originally I thought it might have been something to with the custom rom I installed last week so I completely wiped the phone and reset it to stock rom. I then ran the service test via *#*#7378423#*#* and ran a touchscreen test. This sowed me exactly where the digitiser was unresponsive.
The strange thing is that it sometimes works but more often than not there is a defined area where it just will not respond. Anyone know what the exact problem is?
By the sounds of it, you probably need to replace your digitizer. You could try taking it apart and try checking the digitizer's connection. Mine ended up getting loose, and the screen ended up being unresponsive unless it was tilted a specific way. If you need a guide on taking it apart, there are some fantastic guides on youtube detailing the disassembly process.
i am having the same problem..... replacing the flex cable will tell you if it works. Hold tight

Don't know if anyone else is experiencing this with their Play but as of a week or two ago the backlight started acting strange. The backlight will randomly stay off when I push the power button with the slider gamepad closed. Only way to make it come on is to pop out the slider. It seems to be random, and if I push on the slider edge slightly with my thumb with the slider closed the backlight randomly flickers, ranging from slight to severe.
The display is still working despite the backlight issues, I can open apps, and use the phone normally but the backlight flickers on and off. Makes it especially hard to use the phone in the dark.
Phone has never been dropped once.
I've replicated this problem with a variety of roms, both custom and stock. It's definitely not app related or even custom kernel related. It happens on a fresh wipe with stock rom with stock kernel. It happens on CM7 with custom kernel.
I'm curious if anybody else is experiencing this. It would tell me if it's just an isolated incident or if others are having this problem.
Sounds like a faulty connection to the backlight to me.
I had the same problem 2 days ago. Then I couldn't get my phone screen on at all!
I sent my phone back to Sony, even thought I bought it second hand. Phoned them up and talked to them. They asked what time of year I bought it so I said around August and then they gave me the address to send it to. Now I'm just waiting to see what happens next.
If your going to send your phone to Sony for repair then make sure you put the fresh firmware back on and un-root your phone as that breaks the warranty (unless they don't know about it)
Hope I helped you. If I did then click the thanks button
Sounds like a faulty ribbon cable to me. (cable that connects the screen to the rest of the phone)
You wouldn't need to drop it for that to go bad, It could just be a case of opening and closing the gamepad or lot.
Yeah good thoughts, most likely the ribbon. That really sucks because I've only had the phone for 7 months, and I've taken excellent care of it. Sounds like a major design oversight.
Mine is probably near complete failure at this point. It's taking a lot more effort to keep the screen on now. Fearing soon it won't work at all.
In hopes that this might help someone else down the line, I was able to fix my problem. Yesterday the screen pretty much quit and I had no choice but to try and solve it myself or buy a new phone.
Using this disassembly video as a visual aid I carefully pulled my phone apart: http://www.youtube.com/watch?v=-3n5ZfkqhzE
You'll need a torx T5 tool to pull out all the screws but they are cheap.
Underneath the phone and jammed into the screen ribbon was a rather thick hair just hanging out. Somehow it buried itself in there. I removed it, unplugged and replugged the screen ribbon and cleaned the dusty inside with a q-tip and reassembled it all together.
It works fine now, so hopefully this helps someone else avoid having to pony up for a new phone. For those under warranty probably best to send back but for those like me with no warranty it's worth the shot.
Hi guys. I know many of you have had touchscreen problems and whatnot, i searched but it seems like this one is a bit different from usual. Yesterday the phone was totally fine; i woke up this morning and it had a lot of touchscreen problems: at first it registered touches without me doing anything, but after a couple of reboots it was just unresponsive. After another reboot and some messagging, the problem reduced to a strip on the screen simply not working. The strip is located exactly where the first notification on the status bar is (like when you receive a message and you click on that notification). I have the trueancestor stats bar buttons, so that zone is a tad more down than usual. Anyway, all I did yesterday was a quick game. I think it may be the flex cable not working because of the sliding, but it happened all of a sudden, not gradually. I must say that some weeks ago I had the same "registers touches by itself" issue when typing, but a simple reboot was enough. I tried doing factory reset, but nothing so far. Also I can't use pc companion to flash everything stock back (I unlocked bootloader months ago, even though I relocked it; I dunno if it's locked or not right now), and I can't seem to find a working flashtool download link -_-. I don't think that would help much, it probably is a hardware problem, but who knows. I'm on true ancestor 1.6 LE, stock kernel.
Any help would be great, as I fear the phone will get refused in assistance because of bootloader unlocking.
Did your phone had contact with water? When my screen had contact with water it registered touches randomly.
it didn't. it has a screen protector anyway; but that's not the problem for sure. it doesn't register randomly, simply a strip doesn't work now...
Hardware problem. Could be flex cable or digitizer.
Today there were two moments it began to work again, but a few minutes after each one the problem came back. Sigh...
Mine does that when the screen is moist or my hands are too oily. Are you sure you're working in a dry environment?
mhh... exactly that? I dunno, my hands are dry and i think the screen is too; it has a quite thick screen protector (the skinomi one), so even if it got moist that shouldn't be a problem, right? I'm now living in a different town and that may have changed something, but the problem didn't show up until now, and it was sudden.
Also, I noticed that using gamekeyboard on a certain profile I had buttons placed on the strip, and pressing hardware keys mapped to those buttons actually works. This restricts the problem just to the actual finger-touch-detecting mechanism. Does anyone know anything about this?
Edit: lol I heated the phone up a bit with a hair dryer. It works now. I hope it will last and I'll not have to do this again over and over
Hi all.
My phone's display has been getting progressively worse and worse over the past couple weeks. Initially, when I flipped out the keyboard, the screen would get garbled. I could technically still interact with it (it still responded to stuff), but the display would start glitching out and move all over the place. It's like there's tons of scanlines and it repeats the same display again and again.
When I went back into portrait mode, things were fine. This was extremely awkward but I dealt with it because I had little choice.
However, over the past couple weeks, the problem's gotten progressively worse. Holding my phone a certain way would cause the screen to glitch up again. It came to a point where I had to flip out the screen and keep the flex cable positioned a certain way so I could see the screen. I'm using a dull edge to kinda poke that flex cable around and it helped me gain use of the phone, but today it's gotten so bad now it refuses to "undo" itself when it boots and no amount of poking and prodding of the flex cable will help.
It looks almost exactly like this guy's phone (not my video):

Luckily, I was able to get a VNC server installed on the thing, so if you guys think it's a software issue, I may be able to get it to do something, but I'm not going to be able to interact with the phone if I put it into Clockwork Recovery mode, so doing a hard reset is out of the question.
I'm having a flex cable come in and I'm going to get some local assistance disassembling and installing it, but before I do that, had anyone had this issue before? What did you do to fix it?
best guess is you need a new flex cable

So, initially I began having problems with "ghost touching", then, portions of my screen became unresponsive to touch in addition to the "ghost touching". I did the line drawing test multiple times. At times, it showed a dead space to the right (vertically only, horizontal was ok), other times, it was working fine. I was so focused on checking the right side of the screen, I didn't check the bottom. When I did, it showed an unresponsive area at the bottom as well. Almost as if the screen was off kilter. I did a factory reset through the normal phone menu and from TWRP and the ghost touching has seemed to resolve itself, however, the unresponsive screen is getting worse. Now a full 1/3 of the screen on the right is intermittently unresponsive.
I am hoping there is something I can flash on this phone that might assist the digitizer if it is software related. If not, could it be that the cable is not grounded properly or has possibly become partly unplugged? I know what a pain this phone is to take apart because I had to take my first M8 apart when I accidentally gave it a ride home in a cup of tea. (really tired after working one night, forgot the cup was in the cup holder). Turns out they really don't like that. My current M8 I bought from a private seller, so I have no warranty, no insurance and extremely limited funds at the moment for handling this problem. I've had this replacement phone for several months, so I know the phone wasn't defective when I got it.
I am rooted, running stock ROM, stock kernel and TWRP Recovery v2.7.0.2
Thank you in advance for any help.
The battery on my HTC 10 was completely shot and needed to be replaced. I'm a careful person by nature and this being my first phone repair, I bought an extra screen just in case something happened getting it apart. Followed a guide by jerryrigeverything on how to take apart the phone, got the battery replaced, everything seemed to go smoothly. When I went to test the display before screwing everything together, the new screen I installed lit up, but the right half of the display only showed as a repeating segment from the middle of the screen. Thinking the connector was loose, I disconnected and reconnected the display and made sure everything was tight: same problem. I reinstalled the original display, which I made sure had worked after cutting through the adhesive before I disconnected it, and now the old display is also showing the same issue.
The touch screen on the broken side of the display still works, I'm able to type PIN numbers and whatnot even though I can't see them properly. Only thing I can think of is maybe the connection actually got some debris or something inside of it? I don't think I damaged anything, as I was super careful, but it was also my first time opening up a phone.
Sorry for the inefficiently worded post. Any help would be really appreciated.
Did you resolve this?
I have exactly the same issue you describe after my screen replacement (with two new screens) Believing the first was a dud.
I have done many screens/batteries on my m7, m8's previously never having a problem.
I'm currently back to running my M8 and miss my 10!
Anyone reading this and has any suggestions they are all welcome!!
Thank you in advance
Exactly the same issue this guy has

I'm now wondering if it is just bad aftermarket screens?
Has anyone else replaced their screen successfully, if so where did you get the screen?
Thanks Rory
I have been having the same problem. I just tested screen number 4 that has the same exact problem. Is there a specific brand that is known to test well?
I dropped my 10 in water at work...believe it was a salty water at that. It stopped working completely. I opened the phone to check the internal components for damage and I broke the LCD doing so. I replaced the battery and the screen at almost the same time. I think it may have been a week or two apart.
The battery is still working. The screen worked initially but the phone kept getting really hot and the heat kills the phone. I tried keeping it cool at all times which kept it operational. It hasn't been activated since I quickly replaced the phone with another of my lines upgrades. I went back to the phone to check it out and try using it as a replacement for my daughter but the screen no longer works.
The battery charges just fine...the led light indicates that well. I've tried reinstalling it several times with no success getting the screen working again. I tried the original screen to check and I could see light and it was responding but its not usable so I'm stuck with a phone that has a new non-working display. I think the brand was called DIYRepair or similar.
If anyone has encountered this and has advice...I'd be happy to try anything.
