Dead Touch Screen?? - LG Optimus Black

Hello,
My Touch screen doesn't respond to touching since an hour ago.
I see no logical reason for this fault,
My screen is guarded and nothing happend to it.
I tried to remove battery and insert it with no luck, I booted my phone into CWM touch recovery, and it also doesn't recognize touching.
update2:
The problem appeared again.

just flash a kdz to return to stock rom

The problem appeared again I tried a lot of times to remove battery&insert but it doesn't help.
Please help me.

I've just flashed my phone to stock rom,
I'm still having the same touchscreen issues - the screen won't respond to touching.
Any suggestion please?
Is it possible that the touchscreen issue is caused because of the screen protector?

Screen protector protects screen If you have got stock FW back on the phone, just bring it to your carrier and they should do it on warranty.

Thanks for the advice,
I flashed stock rom and now when I turn on my phone It shows me the "Android Welcome Screen", Is there a method how to bypass this screen without touching the screen? (If I'm taking phone to my carrier, it might seem strange to them that my phone shows the "Welcome screen" whether the touchscreen doesn't work so they could know I flash my phone and not to accept my phone's warranty)

You can try on-screen phone, which is a software by LG, but i think, that this also needs to be setup first... Otherwise, just tell them, that you did a factory reset, because your phone wasnt working properly anymore, and thats when your error occured.
I dont see another way... Maybe repair it on your own

I'm going to take my phone back to carrier
But there's very strange thing: the touchscreen rarely works.
I removed the battery for a night and when I got up in the morning and I inserted the battery and turned the device on, for a few seconds the touch worked . What does it tell about phone?

I've just received my phone from repairing, and my touch screen has been replaced.
I'm a little disappointed because I expected for getting new phone(I have a warranty). I've also noticed that the screen is a little thicker, about few mm, which is weird.
Is it right that phone with replacement touch screen won't be as smooth and good as normal one, or not necessarily?

Same problem of Freezing screen
Disappointing but i too have this very same problem with my brother's P970... any ideas how or why?
though sometimes it would respond but leaving it a few minutes would again make it freeze. The hardware buttons work but the 4 touch buttons wont. now i cannot get thru the rom manager to make it into Bootloader mode so i can install another rom...
some things i did a few days before this happened:
1. flashed CWM recovery successfully.
2. installed a lot of apps and happened to fill up the SD card.
3. installed a new ROM Gingerbread Repackaged V20N
I can still get to S/W Upgrade but all I need is the Bootloader Mode. I honestly dont think this would be a digitizer malfunction since it works well in a given time. It's like it lagggggs much and unresponsive. I cannot get past the lock screen. Any ideas or any other way to get to the B/L mode? Thanks.

ARZAKEM i have the very same problem too i was also doing the same stuff which you atempted and end up with none responsive touchscreen.
my phone is since then lives in a my draft in the kitchen and i was also curious about the malfunctionality because it worked sometimes and other times not.
I just thumbled upon the post when i search the web i know its too late to ask but could you please please tell me what you done with that phone ???
I ordered a new touchscreen from ebay and it will arrive soon but i was wondering wether you managed to fix it or not? could you please tell me what was the real problem did you replace the touchscreen or is it not the touchscreen?

You need to indicate your current ROM. Then can the issue be accessed

G1 Unresponsive - Requesting Help

My friends G1 is unresponsive whenever the screen is closed, but seems to work when sliding it open. The funny thing is, while the device doesn't perform any actions when the screen is closed, it still seems to be responding to touch. When the screen is opened again, your touched actions will "catch up" and the phone responds. This happens from recovery mode as well as in Android.
Can anyone help?
Anyone? Please?

The phone is in standby/sleep mode while screen is off, so you cant use the touch screen. You must double tap Menu to get to the home screen.While in recovery mode you cant use the touch screen cause you have to use the hardware buttons or the trackball. Im guessing you were unaware that the phone goes into sleep mode. When you slide the KB the phone wakes from sleep mode and allows you to use it.You only have to slide it when you need it not just to do it randomly.
No no, sorry if I worded it incorrectly. The screen is on and it is frozen when the slider is closed. Once you open the keyboard, everything works fine. As soon as you slide it in, the screen freezes on its current display and stops updating.

What rom are you using?
If it is a hero rom then it doesnt work while in landscape mode so you cant open the KB while on home.
Its a 2.1 ROM by Kingx
The screen behaves the same in and out of android though...such as in the recovery (JFv1.4) console. If the screen is closed, the screen "freezes", but the frozen picture is still displayed. If you slide the screen ouţand expose the keyboard, it works fine. The phone otherwise operates normally, as does the standby mode.

You need to upgrade your recovery though
http://forum.xda-developers.com/showthread.php?t=566669
Try wiping and reinstall the rom and wipe everything.Also you need a task manager cause you might have a billion apps open.
I'll try it on his phone when I get off work. Thanks for the recovery link. Do you prefer this over JF?

JF is super old and lacks many features from Amon_Ra. But it's based off of Cyan 1.4 recovery. It makes a lot of things easier like partitioning,wiping,backup,restoring roms.
Alright,
Home now with his phone. I swapped JF's recovery with RA. The issue still exists, and I'm wondering if it's hardware related...
This is frustrating. I don't know if I can fix it for him...
The problem seems to have gotten worse on its own. If the screen is closed at all, the screen will go black with a slight image shown with what seems to be an unworking backlight. However, upon sliding the keyboard open again, the backlight does not return until the device is rebooted while leaving the keyboard open.
Edit:
The backlight seems to come on sometimes when you slide the screen open...

You might wanna wipe and install another rom to see if the problem stays.There might be a hardware problem with your phone.
I've wiped and tried a couple of other ROMs but the issue persists. If it's a hardware issue, is there anything I can try to fix it?

It could be the ribbon that connects to the display.If you can find the assembly guide you could replace the broken or loose piece.But i'm not 100% on which part of the display needs to be replaced.You could ask someone at T-Mobile or at a electronics store what the problem is.HTC offers a free 2yr warranty so you might be able to get a replacement.
Bumping this to see if this was ever resolved. Having the same issue, and considering replacing it brand new, but wanted to know what exactly needs to be replaced so I can order it.

Cannot use touchscreen with keyboard out

I don't know when it started but I'm quite sure that I used to be able to use the touchscreen with the keyboard extended. I am running the latest hboot and radio with the cyanogen nightlies and newest pershoot kernel.
Is anybody have this problem?
Perhaps I just need to reflash radio and hboot but its weird because it works fine with the keyboard closed.
Thanks for your help.

Your definitely supposed to be able to use the touchscreen when the keyboards out, That's how I use my phone most of the time. I think it's a hardware problem to me like some cable to the touchscreen got messed up so when you open up your keyboard it gets disconnected, but I really don't know could be wrong. Also, I don't see how reflashing hboot or the radio will fix it, as far as I know they don't affect the touchscreen at all.

As "Ianlikescake" Said its hardware not software. I work in a second hand phone shop & the most common problem with the G1 (Apart from people abusing this beautiful device) is a ribbon cable tears in the back when the screen has been opened & closed a lot.
Normally when it goes the touch screen goes completely but we have had one customer when the same thing happened to him as in your situation, We sent the phone off to be repaired & all they did was replace the cable
So re flashing the radio & hboot wont fix it, Sorry!

My phone has a problem not really similar but it still has to do with the screen. When i lock the phone and when I try to unlock it when the screen is down the screen doesn't turn on. But when I flip the screen up the screen turns on. Once I unlock the phone the screen works fine i flip it back down and it works untill it locks. So do you think it's a problem with the ribbon cable?

I think I have a similar issue. Whenever I have the keyboard closed, the screen will not turn on when you press the end-key. Only the LED lights will turn on. When you flip the keyboard out, the screen turns on and the phone is functional.
Over the next few weeks, I then realized that this only happens when the phone's keyboard is completely closed. If you leave the keyboard out 1cm or so (to the point where you can only see the spacebar), you can turn on the phone. Check to see if it works for you.

That used to work for me but now the problem got worse. Sometimes even when the keyboards out the screen doesn't turn on so I have to mess with the screen for a little bit till it works. Now I know it's the cable that's messed up. I think the reason it's like this is from repetitive flipping out the screen. I gotta be more careful next time if i can fix it.

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..

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!!!

Touch Screen unresponsive!

Has anyone had issues with their Z3 compact screen becoming unresponsive to touches? This happened to me last night even after hard shutdown via power button + volume up key.
My phone is encrypted so after restarting, I was stuck at the code unlock screen but the touch screen was completely unresponsive. After a few more hard shutdowns, a few hours off and alot of cursing, the touch screen finally started working again as if nothing was wrong.
Any ideas guys? I don't want to send this phone in if this was a one time thing, but I'm afraid it won't be the only time...
I guess I'm the only case of this happening?

It can occur for lots of reasons
This can be only software lag instead of touch panel problem.
and even 3rd party app can freeze your phone like this.
anyway the possible solution and way to understand if it s software or hardware problem is to repair firmware by PC companion
:good:

The reason I don't think its software related is because after the reboot my phone goes into the device encryption unlock menu right away. This menu theoretically should have little to no software loaded at this point, yet it still didn't response to touch. Now, I did recently downgrade from the latest UK ROM to the next available U.S. ROM. Not sure if that may have affected anything...
No more problems yet though...

Was the phone wet? Water can mess with the capacitive screen but shouldn't still be a factor after drying it with a rag. I'm assuming you realized this already, but doesn't hurt to double check.

My Z3 do this too.. i dont know what to do
Same here. Happend 5 minutes ago and since no response from the phone -.-"
I hope it settles itself again.
Edit:
Now it works again. Strange behavior
I just returned my Z3c because of a touch screen malfunction. But in my case, it wasn't unresponsive, it just went nuts. It located taps at totally different spots from where I was touching, so typing, scrolling, etc. just was impossible. Luckily, this state only lasted for a couple of seconds up to a minute max, but occurred several times a day. Phone now exchanged for the "big" Z3 (due to arrive tomorrow), hope it hasn't the same issues.
I have found the reason my phone was unresponsive. I disabled some apps through adb, one of them seems to have caused the issue (dunno which though).
So I just restored the phone using the pc companion and since then no unresponsive touch screen.

Z3 Compact top half of touch screen not working
The top half of the screen of my Z3 Compact doesn't register any touches anymore. The bottom half is OK.
The phone wasn't dropped or anything. I did a repair with PC Companion and nothing, still the same....
Sigh!
hello, well the same thing is happened to me but my phon is z3 dual, this happened just before hour ago
Any solutions ..
I've just bought it about 2 weeks ago
I have the same problem, the touch is not responding and I can't use the phone since yesterday.
did reset by buttons and also by that yellow reset button and still nothing, it powers on but I am stuck when it asks me to enter the PIN code, because the touch is not working.
Anyone got a solution for that?
Which apps you have disabled on adb and say cause that issue?
Same trouble over here. Experimenting this unresponsive touch panel since today, several hours without working at all. I just blocked some boatware apps, but this should not affect touch panel, right?
Just restored the whole phone using official from Sony PC Companion software. It remains the same trouble with touch panel.
Today, in house, we put the phone under tap water just a blink. Do you think this could have damaged the device, though is water resistant? Do you know where are the humidity sensors, that could have change? Thank you for helping!

Shot in the dark here. If you're getting vibrations and response to touch, my best guess would be that the screen itself is damaged. May have to get a new panel for the device. I wouldn't THINK it would be software related, but for the sake of ruling things out, what software is the device running? Custom ROM? Stock build?
EDIT: It could be a simple thing like a loose or disconnected ribbon cable inside.
stock,
it actually happened after a reset (and shipping by USPS)

This is the phone where you hit factory reset, threw it in a box and shipped it while it was resetting?
Probably the screen was damaged in shipping.
