[Q] Digitizer behaving weird, broken or can it be fixed? - LG Optimus 2x

Hi all! My friend was drunk, dropped her phone on the ground, broke the digitizer glass. I bought a new digitizer from eBay, and after 1-2 hours I've managed to exchange the digitizer, boot up the phone, everything works - except that the very left pixel row from bottom to the top recognizes touches as if they were touched on the right side.
For example, when I press A (at the very left side of the A key on the keyboard) it recognize it just if I touched the screen on the right side instead.
When running tests and pressing on the very left pixel row I get straight horizontal lines over the screen, one line for each touch. That doesn't happen if I tap on the right side or if I press 1 millimeter from the very left row.
So, my question is: Is there any script, setting, hidden hardcore setting or something like that, that will disable the very left row of my digitizer? I think the digitizer is malfunctioning, or is there any calibration tool I could run?

Hi,
I suggest you get a replacement for the faulty digitizer you got. Just complaint to the seller to ship you another one. It is better that way.

Ah, okey. Thanks Will have to buy another front frame thou

ATT Tilt: Changed broken screen, now touch doesnt work

Hello, I am a true noob so please forgive me if I sound dumb.
I had a broken screen so I bought a new one on Ebay. I changed it perfectly, it looks good but now when I touch the screen it acts like I touched the top left corner (in portrait)no matter where on the screen I touch (so it opens up the "Start" menu). In landscape it acts like I touched the top right so it opens up the drop down menu with all the running programs.
I would really appreciate some help. I try re-aligning the touch screen but it does not recognize any touches at all. I have to soft reset the phone to get out of the re-align program.
I don't want to hard reset because I have read many cases where the phone gets stuck in align program as it is trying to setup and they have to install remote access or something to get around it.
I would like advise on whether it is the new screen or the phone. Is there something I can check for inside or should I send the screen back for a replacement.
Thank you for your help.
Having replaced the touch screen in a Palm with success, I would say that...
You either have a problem with the connector for the screen, recheck the connection
Someone sold you a bad screen.
Something else is wrong with the device.
At this point I don't know that in your position I wouldn't do a hard reset. What is the worst thing that can happen? The device is already broken in it's current state.
Good luck.
Thank you
Thank you very much for your help. I will try the connector. if it does not look damaged then I will return the screen.
Did you replace just the screen itself, or the screen and the digitizer? More than likely your digitizer is broken aswell. If you replaced them as a set, request a new one from wherever you got it, and if you just replaced the LCD, then you need to buy a digitizer aswell.

Well, I only received the screen. I cant figure out where the digitizer is on the tilt so I don't know if I changed it or not. Does any body have any picture??
I think I read somewhere that it all comes as one piece(the screen and digitizer), but I can't confirm it.
Indeed they most of the time do come as one peice, so if your connection is good on the mobo, then I would say that the digitizer you recieved is bad. The digitzier is the super thin peice of glass that covers the LCD screen.

**~htc touch screen not working!!!!~**

hi,
my touch diamond 2's touch screen stop working randomly ( i think that i applied too much pressure on 1 spot for too long). I can see the touch screen dots on the area. I am just wondering if I were to repair this, would i be replacing the DIGITIZER or the TOUCH SCREEN.
Thank you soo much
warranty might cover that. It might not be your fault
I have decided to fix the part myself since I do not wish to ship the part to their location in the US. Any idea if its the digitizer or the LCD screen that i should be replacing?

Search the Wiki, there are dismantle instructions.
I had the same on my display, and was able to move the dark spot to the edges where it disappeared.
I moved it with scratching it with my nail very gently applying some pressure.
In Europe HTC offers a pickup and return warranty, is that different in the US? If it is the same I would send it in to HTC for replacement, since it might happen again pretty soon....
I already have 3 screens replaced :-(
jason, did u manage to fix this? i have the exact same problem and pushing the "bubbles" towards the edge of the screen didn't help. my screen is still unresponsive..

Try applying duct tape to it repeatedly until you get it back.
Yes, both
I recently replaced the Touch Screen on my Diamond 2. Same problem; spots that "stick" in the middle. I used to solve this by running both my thumbs down the sides of the screen to "puff up" the low areas in the middle.
The part you want is actually called a "Digitizer Touch Screen" on eBay, cheap too. Prepare to spend about 2 hours fiddling with very tiny screws, connections and glue to tackle the job.
The hardest part for me was actually getting the Touch Screen to work; it seemed to be calibrated in mirror-image AND turned 90 degrees sideways, which made getting to the calibration functionality an extremely frustrating experience. I spend another 3 hours on that, but now I've got a perfect phone again, since I ordered a new case as well. No use taking the entire phone apart and then rebuilding with a molested outer shell...
maybe you should reset it
Working Solution Till Now
Hello Friends,
I have TD2 mobile and today I had same issue. I was thinking it was because of the weather or some.
I remember it did happend several time before, but when I restart the device several time it does work. So I was ignoring.... But today it did not work.. looks like going toward end... So I did soft and hard reset without and that did not helped me.
So I switched off the mobile, "heated" the touch screen gently with my hand for 1 min and started the mobile again and it worked for me .
Not sure if this is a solution, but will work.
May be I will contact Service Center here in Hyderbad and see what is wrong here?
Hope this will help you all...
Thanks.
Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!
Digitizer replaced but still not working
The touch screen on my Touch Diamond2 stopped responding to my touch (or the stylus) and I tried everything including removing and replacing the digitizer bus just in case the connection was the issue. But all to no avail. Finally I decided to replace the digitizer (touch screen)
The problem for me is that it made no difference. The new digitizer doesn't respond to my touch either. The problem is apparently somewhere else.
If anyone has encountered this problem and has a solution I would be grateful to know what it is.
Thanks in advance
Replace the Touch Diamond2 Digitizer touch screen.
I recently replaced the digitizer (touch screen) on my HTC Touch Diamond2. Since I found on the net, no instructions for replacing the actual digitizer, I thought I might include some here.
It was relatively easy to fit. The only difficulty I encountered was a lack of information about how to actually remove the old one. The various instruction sets found on the web all stop once the screen is removed. But the digitizer is not covered by these instructions. The digitizer is bonded to a thin glass immediately under your screen protector (if you have one fitted) and after the screen is removed following instructions you will find on the net, the digitizer and the thin glass sheet that it is bonded to must be prized off from the front of the housing. The digitizer separates from the glass easily, but the glass is securely bonded to the housing with a silicon glue. It must be prized off by gently lifting a corner and applying a little upward pressure allowing the glue to slowly and gently let go. Don't be surprised if the glass breaks during the process. Once off it is a simple matter to press the new one in place. Just remember to start by slipping the connector bus (cable) through the narrow slot between the metal outer housing and the inner components. I used a set of tweezers to poke it through. DO IT FIRST before pressing the digitizer into place.
Okay, as I said the process was easy and took about 15 minutes all up.

Thanks for the heads up on the glass part mate. Just replaced my TD2 digitizer too. Kinda freaked out at first when the glass split.. haha
Anyway, just wanna 1 more info. When removing the old digitizer, it'll be easier if the front housing was heated first (with a hairdryer on full or a heatgun) to soften the glue. It'll be easier to remove afterwards.
Word of warning though. Only head the housing when REMOVING the old digitizer, DO NOT use this method when applying the new one. The digitizer dies because of heat. Heat is what causes the newton rings issue.

Fixing TD2 touch screen
TD2 touch screen is a common problem I guess.
Symptoms are :
1- Touch screen does not respond sometimes
2- You can see a grease like layer under the touch screen
3- Sometimes if you look closer to the screen at some part you can see a a liquidized small area.
Solutions:
1- If you see the liquidized dot on the screen turn off the display and try to rub it with your finger until it disappears. turn it on again and try if it works. I guess heating with the finger as other peeople here suggest does the same thing. However this is a temporary solution. Your touchscreen will die at some date. I used my TD2 for 8-9 months using this method. But at the end touchscreen died.
2- Replace the digitzer or complete frontcover. Actually this might be easier than you think. I replaced mine in half an hour. I bought a front cover which includes the digitzer (http://www.ebay.de/itm/Original-HTC...zer_Ersatzteile_Werkzeuge&hash=item4cfe6f78dc) and openning tools from ebay. Dimanıond 2 disassemble and assemble videos on youtube were very helpful. I strongly suggest to buy the complete frontcover (inc digitzer). It makes replace process much easier and gives the device a brand new look. My old front cover was worn from the corners (which is also very commpn problem of TD2). Now it looks brand new. No strach on the display and body.
Thnks Ozkarah.
I happened to realize that, surprisingly, the touch screen of my HD2 started working if I heated it up with a hairdryer. So, I think something else is wrong beyond the touch screen, probably the connector to the main board of the mobile. It might expand once it is hot and that is why it starts working. In any case, I think that is beyond repair

[Q] help needed for unresponsive touchscreen

my touch 3g became unresponsive at right lower corner of the screen. within a day, whole of screen became unresponsive
I have the same problem but fot the left part of the screen. Any ideas?
Yuppers. The digitizer's borked. Have it replaced, it costs some 12 Euro on eBay.
I had the same problem with my Jade.With a simple action it came back to life.I took a sharp knife and raised a bit the plastic upper cover on the Digitizer.It worked instantly.Perhaps a small quantity of air or humidity has entered between the Digitizer and the upper plastic cover.This was the problem of my Jade.When i looked on the screen with the light off i could see some shapes on it.If you can see them too,perhaps you're having the same problem.
any tutorial?

[Q] Touch screen not working

My Droid's touch screen isn't working in the center vertically all the way down. I can still use the 'edges' of the screen. I need to use the middle of the screen for a few things (not transfering stuff over). Is there any way I can 'project' my Droids screen to my computer and click/touch in it to use it?
Thanks in advance for all help. It's appreciated
~mfungah
Edit: This is the original Motorola Droid.
I have the same problem on the right side of my milestone :S
I had the same problem, but from the back arrow upwards, specially when the phone got hot. As my phone was still on the warranty period, I flashed it back to stock and updated it to the official 2.2., took it to an Orange shop and got it back after almost a month: they basically changed the whole top part of the phone (I got a brand new screen )
Repair problem
I had a same failure. The touch panel was bad. I ordered one from eBay. It also came as well put it. It works well. Only so much wrong with me that for some reason the phone stacked in landscape mode, I can't change to portrait mode. What is wrong? I put together something wrong? I do not think so. Everything else goes. (or so it seems)
This has to do with the digitizer (the glass you touch over the top of the LCD you see) being defective or unsealed. This is due to environmental moisture finding its way into the phone and f**king with the electrictal signals sent by touching the screen. There is a 'phantom touch' issue that seems to happen before or during the vertical unresponsiveness, and that can usually be temporarily remedied by firmly pushing your screen downwards (your phone may restart) and taking a blowdryer to your phone until it's just hot enough to be uncomfortable to hold (and no longer take it into the bathroom while you shower). One way or another, you're going to have to replace your digitizer eventually.
Sent from my Droid using XDA App
I had the same problem months ago but it's now fixed.
STEPS:
1. Digitizer I bought from this guy:
http://cgi.ebay.ph/New-Touch-Screen-Digitizer-Motorola-Milestone-A853-/270780531 891?pt=UK_Replacement_Parts_Tools&hash=item3f0bc704b3#ht_2811wt_850
2. Dissasembly Videos (I advice you to watch them repeatedly before dissasembly):
http://www.youtube.com/watch?v=6d7ETMfgq2s
http://www.youtube.com/watch?v=dE81IaQHEHc
3. Phillips screw driver( for dealing with hard screws around the screen): Because I don't want you to use the low quality screw driver supplied with the digitizer.
4. Double sided tape: I got mine from a hardware shop for only P19. Buy a the more expensive tape(P100+) but look for a very thin one! You will use the cheap weak tape to stick some internal parts and use the Hard tape to stick the external casing. EDIT: I just used the cheap one for everything and it's strong enough.
5. PATIENCE: Don't be in a hurry. I even paused from time to time to get a better idea about what to do next. Get the feel of being a perfectionist (that same additude when I applied a screen protector )
That's the guide from me who haven't dissasembled a phone in my entire life but my milestone. So if something bad and technical that happens along the way then my knowledge can't help.. sorry.
Good luck bro!!

[Q] Replaced Screen - Dead Spots

Hi
The other day I replaced my HTC HD7 screen, both the LCD and Digitizer.
The cracked screen was working fine, and everything was working perfectly.
After changing the screens everything also came up good, the phone booted up and the Windows Phone menu was working fine.
Problem(s):
On the top right corner there is a dead spot about 1cmX4cm going downwards, I can see everything in the corner but it does not detect touch.
Also, the onscreen key board only works on left side landscape mode. When I am in portrait mode I cant use the "O" and the "P" , and when I am in Right side landscape I can't use the "G" icon/key.
This leads me to believe that the digitizer might be faulty, because the LCD shows everything so it can't be that. Or, maybe the ribbon cable might be bad?
Has anyone else had this problem? What can be done?
Any input on this problem will be much appreciated.
sent it back for replacement if it's under warranty.

Yes, I sent it back, waiting for the replacement now.
Hopefully it will work. I will update the status once I receive the new screen.
