Hey guys, recently I had my Z2 sent to a service shop because it wasn't turning on or charging. The guy at the shop said that it was the battery fault and he changed it, but he also told me that the screen was not working( flickering, ghost touches, unable to work on it). So he put my old battery on and when I went home the phone actually turned on and booted up, but still I had the screen problem. So whenever I touch the screen it doesn't respond and it touches by itself. Tried putting it on rice for 20 hours, dried with a hairdryer and assembled dissamssebled the screen jacks, still the problems wasn't fix. Do I really need to change the whole LCD or is this a problem that can be fixed?

Yes, you have to change the screen, or more precisely, the digitializer.
But since the LCD and the digitialier come in one-piece, you have to change it as a whole, but at a much lower price, as your screen can be sold again and recycle the good LCD panel.

So replacing the LCD would fix the problem right? That's great then because I found an LCD with a very low price (20$), completely new on ebay and I sucessfuly dissassembled the old LCD out of the phone. I'm gonna buy it as soon as possible. Thanks man.

I initially dropped my phone in water (sink), got out immediately and dried in rice. 72 hours later I powered up and all apps work, sound, making calls etc work. The problem is only half the screen works. I've replaced with a new digitizer and LCD screen. And still only half of the screen (same half) works. Do I have any other options? PLEASE HELP Please. My phone was purchased from AT&T if that helps.

Did u replaced the digitizer and LCD or u went to some service center?
Without knowing the problem and changing both the things blindly, surely, waste your money. If touch was not working buddy, then why u replaced LCD?
Okay, now its done, better move on.
If replacement didn't do any good, Then there might be a chance of other hardware problem... You can contact your provider's service center, they will surely look into this matter.

Thanks, I'll call service center. The parts that I replaced were free from a friend, so no loss of money. The screen was cracked from a previous drop but still worked fine and the LCD had a couple of white spots after it fell in the sink. So I changed both for reasons other than just the digitizer not working properly.

I also have been having touch-screen problems. Several parts of the screen don't respond to touch. I'd rather fix this phone than replace it.
I am running Android 2.3.6, kernel 2.6.32.9 [email protected]#2.
I see there is no screen calibration for this version.
I have purchased another digitizer screen but have not yet tried to install it. The ATT service center is not likely to help, as I have rooted the phone and enabled side-loading and mobile tethering.
Two questions:
1. Could changing to a later Android version and doing a screen calibration fix this?
2. How should I prepare for replacing the digitizer, other than a Titanium Backup?
I just got done replacing my broken screen on my LG G3. I replaced the whole front panel and just transfered the guts. Everything checked out fine after replacement until i typed my first text message. row A-L will not goto screen unless I touch nearly inbetween the middle of the row beneath it. q-p work fine as well as z-m. What really has me boggled is that the screen accepts touches there in virtually every other app/drawing. Just the keyboards aren't allowing touch in that specfic row. any suggestion?
Found a few more bad section.. Pulled the back loudspeaker back out and tried reseating the cables and still had same issue. They're sending a replacement for free.
This was my first screen replacement, but not my first time dealing with small ribbon cables. All cameras function fine, hoping it was a defect in screen and not my screen changing abilities.. Any tips for the next one would be appreciated. Would like to have a fully functioning phone again sometime. This is nearly more frustrating than the broken screen.
I am having same Issue

Hey just curious if your issue has been resolved.... I am having same issue, but i took mine to a computer store i have been dealing with for years. about a year ago they started doing cell phone repairs as well. I had them replace my cracked screen on my LG G3 and that same row of text if off for me and there are a few other spots i have noticed are off as well .... very frustrating... Anyway the place I took it to has replaced 3 screens hoping they were getting defective parts.... they just called to tell me I can come get it but they were unable to repair the dead spots without going further into replacing boards or something.... I dont know... It is weird though cause you can get the dead spots to work sometimes by very lightly touching or just touching it in just the right spots like a calibration if off....

A review on G3 LCD's on Amazon reports the same problem "I installed the screen and immediately my wife mentioned that it seemed to have "dead spots" when she was texting / playing games. I noticed it myself when I tried texting myself as a test. Several of the letters on the keyboard just wouldn't register very well. She went into the settings and ran the "motion sensor calibration" test under general settings>gestures. This has resolved the touch screen issues. "
I don't see how that would fix it but I guess it's worth a shot.
Hi,
Trying to fix a Z2 for a friend. She dropped it, smashed the screen. You could still see the LCD, but the digitizer was fubar. Ordered a new screen assembly, but after the replacement only the LED backlights work - no LCD at all. To test, I reinstalled what was left of the old screen, and no LCD, just backlight, so I don't think it's the new screen. So then I ordered a new main ribbon cable and replaced it. Same result: no LCD, just backlight. You can hear the phone on when it's on, the phone "responds" when you touch the screen, you just can't see anything. I upgraded to the latest software update tonight using PC Companion, but no change.
So, the only thing left is the motherboard, right? I know there is a fuse on the motherboard that, when it fails, it kills the backlight and leaves you with only the LCD. I have the opposite problem. I'm hoping maybe there is something like that for the LCD??
Thanks in advance,
Heath
I have same issues with you and also try ten new lcd all show backlight only..what your solution??
Have you tried to connect it via a MHL cable to TV ?
Hello!
My phone fell from a high place some weeks ago and the screen shattered. Touch was unresponsive, clicking everywehere, but LCD was fine, i could see everything on screen normally.
Ordered a new screen. Changed it, but when I turned it on, only backlight of the LCD was visible, but it was displaying nothing. I thought it was a defective screen (either way, it was, lots of stuck pixels), sent it back and bought another from the same seller. When I changed it and turned it on, again, no video output, lcd would light on but woundn't display nothing on screen. Googled a bit, found out it could be a defective fuse on the motherboard, and that soldering it again would solve. I know nothing about this kind of stuff, so I picked up a tweezers and apllied a little force on every fuse, because I thougth that way I could try to solve it. Well, it worked, kinda. I put the screen above that blue plastic glue only for testing, and it worked, I felt reliefed for seeing sony boot logo again. Figuring out it had worked, i took out the screen, took out the blue plastic, and glued the screen back on. For my surprise, it had the same problem as before, and it doesn't matter what I do now, it wont work anymore, only displays a black backlight with no video.
Could anyone help me out with this? Give me a hint of why it worked once but not anymore. Could it be there's really a defective fuse, or it was just a coincidence that it worked after it had force apllied? Also, the Screen flex is kinda loose, it keeps coming off all the time, and it's really hard to plug it to the LCD sometimes, is it supposed to be like that, or could it be the culprit? Also, touch is working normally, i can't see nothing on screen but i can click and feel it vibrating.
It's kind of a big text, but that's the way I could explain it. Sorry for the bad english, it's not my native language.
And thanks in advance if anyone can help!
Hi guys,
when my phone is in charge at 100%, after some minutes it start to flickering when there is at least an orizontal black line and a white part, for example if there are 2 notifications there is an orizontal black line that separates the two notifications, right? The white part of the notification start to flicker. I tried to hard reset and nothing changed, and also got my display replaced and nothing changed (huawei customer service said they will replace the mb, but idk if this will solve my issue).
Anyone have this issue or it's really a faulty mb ? I tried searching online but it seems that no one have this problem.
I'll upload later a video that will show my issue...
Have you dropped the phone? Even from a small height it could cause problems.
My old p10 plus fell out of trouser pocket and hit the inside of door panel but was enough to cause screen flicker.
I had a hairline crack in digitiser/screen.
It only showed when screen brightness was on low or if phone was cold.
Got the screen replaced and was ok after.

I dropped my phone only 1 or 2 times and always with protection, but even after the display replacement the problem didn't solve. It only flicker when it's in charge and already at 100% and when I unplug the charger, it stop. I noticed this problem only after I got my display replaced for the gluegate... but even after a second replacement nothing changed. I hope after the mb replace, my phone stops to flicker.
I have the same flickering problem with my Mate 20 Pro and have never dropped my beloved smartphone. For as of right now, the current (.232) update may have resolved the issue but it's only been a day since the patch. I will see how it goes.
edit: nope, even after the (9.0.0.232) software update, the flickering issue still remains as the original poster has described.
