[Q] Touchscreen stopped working after CM9 latest nightly build update - TouchPad Q&A, Help & Troubleshooting

So heres what happened. I had a perfectly working touchpad with CM9 and webOS dual-installed. In October it was dropped and the screen shattered. I ordered a replacement digitizer screen for a Chinese Ebay seller. It arrived last week. I swapped out the screen(which was a pain with all the glue and the shattered pieces stuck on it). Anyway after swap and charging the tablet was working great.
I decided to download the latest Cm9 nightly build and installed it from recovery. reboot and now screen would not respond. First I thought maybe the connectors have come loose, but opened it and everything is intact. When I jiggle the connectors I see movement on the screen, so something is going on.
I want to reboot but I cant figure out a way to hit the reboot on the screen after I press the power button. All physical buttons are working fine. Is there another way to reboot this device?

Hold down power and home buttons at same time for 20-30 seconds and it should reboot. If that fails, try holding down power button and tapping the home button repeatedly, maybe 20-30 times or more. Good luck!

I was able to reboot but touchscreen still does not work. probably do a tradein or just throw it in the trash.

Does anybody know if an unreponsive touchscreen would be counted as in good condition or fair condition for tradein?

I would say of course not, it is called a Touchpad if touch doesn't work then its not fit for use.

I'd exhaust all other possible fixes before tossing it completely. And even after it was pretty clear the TP wasn't operable, you may find others who would buy it to get some of the parts that may still be good.

Segment of touchscreen on Milestone not working?

Hello,
I'm not really sure if anyone encountered this before..
Suddenly today in the morning, I notice my Milestone's touchscreen is acting up.
I can't reach the menu button at the bottom of the screen. It always chooses Phone or Web Browser button instead :/
I use search to get to Dev Tools and Pointer Locations, and I realize there's a segment, about 1 third of the touchscreen, in the middle, unresponsive to touch.
I tried cleaning the screen, clearing cache, rebooting, it made it work temporarily, but then it returned again. I changed to stock 2.1 SBF, still no change. And now, its stuck in this state, I can't get it to work even temporarily..
I really dont want to send it to Customer Service, is there anyway to solve this?
Thanks!

Same with me, i can't reach from menu in a bottom side to upper side, maybe 10mm dead space + 7mm right side from bottom side to upper side.
Please help me!!
Sorry my english is not good
It happen to me last 2 weeks while helping out a friend's Milestone. After i flashed a kernel, the whole screen is not working. Trying to flash back to stock ROM,custom ROM,etc but still the same.
By accident i press and hold both BACK key(the bottom left) and SEARCH key( bottom right) and ON the phone. I let go of the the two,BACK and SEARCH key after the phone is completely ON. To my surprise, it works!!! Until now the phone has no problem with the touchscreen.
I hope you guys can try this out or is it an coincidence,I don't know..

thanks but no fix it for my phone
I had the same problem sometime last year, which I eventually fixed by clearing cache partition and rebooting a bunch of times.
Unfortunately, the problem re-appeared today. So far, rebooting and clearing cache hasn't worked.
By any chance, have any of you installed the WiiMote Controller App? I was convinced that was what was doing it to my phone. (maybe not, as I never re-installed it though)
I'm about to flash the sbf file, but as Lesiroth said, that might not work
i believe u r having GHOST TOUCHSCREEN syndrome
my touchscreen sometime do not response to my touch
it just went berserk!
the notification bar keep sliding up and down
if im in the menu, it goes up and down too!
sometime i cant unlock the screen bcos it do not respon
however, some chinese users found that this could be due to ripped/ torn ribbon
just google it
it is widely reported too!
I just want to say that I have fixed my Droid's touchscreen problem (or maybe it will re-appear in another six months).
Anyway, I just set the screen brightness to max and screen timeout to 30min and let the battery drain. I took the battery out for a second and then charged the phone with the USB that came with the phone over the wall socket.
I think the USB wire is the culprit (I was using a BB one for a while).

my problem seemed to be disappeared after i soft reset n use stock rom
i tot launcher pro was the culprit but it is not
so i re-install LP n use for 1 day
d only problem i had was when i went for a jog, i tucked it on my waist (no in the pocket).
after that the screen stop working at all, i have to reboot by taking the battery a few time.
after 30 min or more, the problem was gone.
tis could be due to the stress applied to the screen when im joggin (as it it as "touched" while im jogging).
however, i removed beautiful widget n its addon too, dat could the source of the problem as well.
SOLUTION: soft reset, use stock rom / launcher for 1 day
if it still persist, it could a hardware problem

I am glad that you solved your problem. Unfortuntely the past week or so has been a really busy time for me, I could not focus on this problem. I will try your solution, although I still think it is a broken digitizer on my part.
maybe the problem is the digitizer..
try to change rom or wipe it first..
if the problem still persist i think its the digitizer..
use only the original charger..
OMFG that worked on my phone!!!

thanks in advance

problem with replacement LCD+digitizer

Hello,
I know a lot of us are having problems with displays and digitizers and im wondering if anyone else has this problem. Yesterday i replced my screen because it had a dead zone. I booted up the phone and everything worked great until i locked the screen. When i pressed the power button to unlock it there was just a black screen with lots of white lines forming. Without fail the phone will do this. I restart and its fine but when i lock it, it gets screwy. I really need to get this working since i dont even have a backup phone right now. By the way the display is not oem its a knockoff.
Since you change your LCD....it might be a different panel from your original. Check your kernel or flash the kernel again.

Same thing happen to me about a month ago during my G2 screen repair. I bought mine on ebay from a seller that had sold hundreds of them, figured I couldn't go wrong. Unfortunatly I never figuered out why it was failing and just ended up returning it for a refund. The second screen I bought was from etradesupply and it worked perfectly. Hopefully someone has a fix for this weird issue.
I had that exct thing happen to me, well rainbow colored lines. I shattered the screen on a corner drop. I took it to Gopher Mods, they replaced the screen and within a few minutes it happened. They replaced it 2 more times and eventually the last time the screen popped out a little bit since they did not add enough glue/sticky tape inside and the lines dissapeared. They also gave me a full refund, with which I got another G2. So two working phones now lol.
Basically the screen might be pressed in too tightly causing the cable inside to be kinked too much. Its very easy to damage the video cable in this phone mind you.

Try installi mg dorimanx's kernel which detects your panel type of search the thread for a kernel swap flashable. Your new panel may be of a different type causing the white lines.

Power/lock button doesn't always work

Hi everyone, my Nexus 6 has been behaving weirdly from a week or so, I had the same problem months ago but it stopped happening and now it's back again: sometimes the power/lock button stops working. Like right now I'm typing this and I can't lock the phone by pressing the button but I've to wait 1 minute so it locks automatically, I can't keep reproduce the problem it just happens randomly. Another thing I noticed is that once it locks automatically it starts working again.
I'm on chroma rom, lean kernel and flashed viper4android and xposed.
Any way to troubleshoot this when it happens again? Are there any logs which could tell what the problem is when it happens again?
I think the first thing to do would be to diagnose whether it is a hardware or software issue. If you are willing, you could try flashing back to pure stock and see if it still happens. Then you will know whether it is a hardware or software problem.
Happened to me several times on an older version of Chroma. Two versions ago I think. I haven't had it happen since updating to the latest version.

I guess it's a software issue as you're using custom ROM. I'll recommend you to flash stock firmware and see if the issue continues or not. If continues then ask for a replacement
It stopped happening by flashing the latest Chroma build.
Nevermind it still happens from time to time.. I really don't know what is causing this
Which logs could give me an int?

I have this same problem with mine. I thought maybe it was the case... And removing it seemed to help but it would still do it without the case. Its very rare. My gut instinct tells me its software. If it were hardware I think it would be more pronounced.
I will continue to monitor and update this thread.

My own stock based ROM. I think its a firmware flaw.
Only happens rarely.
I had gotten rid of it for a while with a fresh install of chroma but I had to restore the phone to stock and then reinstalled the largest version of Chroma and its back with a vengeance. Seems every time I wake my phone from deep sleep there is a couple second delay before the power button turns the phone on.
Disabling ambient display altogether seems to have fixed my issue.
You could try MeanPop too, he actually designed the ROM so it doesn't deep sleep just turns down the CPU max frequency and some other stuff.
Check the ribbon connection
Check the ribbon connection from the power and volume buttons.
I had the same issue, but with the volume down button. Tried cleaning the button connection, etc, no success. Then I noticed when I had the back off that the power and volume up buttons would stop working when I wiggled the ribbon. On closer inspection of the TINY ribbon latch, I discovered that the top of the latch was loose, and one of the microscopic metal connection prongs was missing. Pressing the ribbon down on the bottom metal prong from the top with tweezers resulted in a perfectly functioning button. So I carefully bent the prong on the far right slightly to the left to cover the spot where the prong was missing, covered it with thermal putty tape, and reattached the back. So far, so good.
You don't have to remove any screws to do this, but make sure you heat the back cover with a heat gun or blow dryer before trying to remove the back, or you'll likely rip the top of this ribbon latch clean off, because it is in contact with the adhesive on the back cover.

@MZO that's might be the solution. At first, my volume key down wasn't working properly and after dropping it, the power also isn't working. Ribbon cable design is awkward and I am sure it's loose.

Replacement screen doesn't work

Hey guys,
I've searched and tried seemingly everything, but can't find a solution to this problem. A few months ago, my cousin dropped her Z3C on the floor; the screen cracked and stopped working. I got and installed a replacement screen, but it doesn't work. When I first turned it on (after charging the phone for several hours), the display was off, but I could touch the screen and I would get haptic feedback.
When I do a soft reset (Vol Up + Power), it vibrates 3 times, but the screen still doesn't display anything. I've pressed the little yellow reset button next to the SD slot, which also causes it to vibrate, but the screen still doesn't work. When I connect it to a PC, it is identified, though no folders are shown in the device. After I used the repair function of the Sony Xperia Companion, I now no longer receive haptic feedback when touching the screen. I also tried using flashtool, but to no avail.
Can anyone point me in a direction with how I should proceed?
Thanks!
It may be a motherboard issue now,try taking the phone apart and reconnecting the screen,but don't close it fully just connect it and see if anything happens,if it still doesn't work it could be a motherboard issue or you got a DOA screen
Make jumper on fuze like I did on 2nd picture and should be fine. Pictures here.

Unfortunately, soldering for me isn't an option.
I've looked into the price of a motherboard for the Z3C and it's pricier than I expected. I might just cut my losses and try to sell it as is.
Thanks for all of the suggestions, guys!

touch screen sensitivity?

Anyone having touchscreen sensitivity issues? I'm having ghost swipes galore while trying to scroll up and down a page like Google now or Facebook. Try swiping left and right on the home screen. On mine it just started to not respond anymore after a couple of times. Even if I go to the multitasking page, I'll try and swept away each open app and it'll just start to not register. This is while not plugged in btw. I really love the phone otherwise and want to keep it but I'll have to return it if this is a common problem. Is this an issue with the phone or just me? If it is just mine then I'll just exchange it and hope I get a better one.
Actually it is much more prevalent while charging. I also forgot my Moto mod battery pack charges constantly and my cause grounding issues also. Let me know if it's just my phone y'all!
I had these issues initially, especially with the bottom of the screen and the back button, but after a couple reboots they're totally gone. Try a hard restart (hold the power button until it restarts). I use a turbopower mod so i don't think its that.
My charging cord doesn't work.I just bought 3 days ago and it will not turbo charge

after reboot initially it's better but then it returns after a few minutes. is it the same for you? does it return? anyone else having this problem because I'm trying to determine whether I should take this back or not and get it exchanged.
Problem was an isolated incident and I'm happy to announce that I exchanged the faulty phone for another and this one shares none of the problems said above. So in short, if you're having screen sensitivity problems, send/take your phone back for a new one.
It's flawless now! I freakin love this phone!
