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

Hi,
I have same problem when I changed new screen (screen is calibrated in mirror-image AND turned 90 degrees sideways).
Could tell step by step how you get your screen calibrated?
Thanks
Hi there. A friend of mine gave me a G1 with a cracked digitizer. I ordered a new digitizer from ebay, and after it arrived today, I installed it. I then powered on the phone and found that the lower ~8mm (in vertical orientation) of the digitizer is unresponsive.
After futzing with it in the maps app, I noticed that if you start your gesture where the digitizer works and drag across the trouble area, the map shutters and shakes back and forth as though it were getting input from all directions.
Has anyone encountered this? Any possible solutions? I'm stuck
Ugh, I thought the digitizer wasn't seated properly, so I dis and re assembled and the issue persists. Is this a defective digitizer?
It's really distressing not being able to use that lower portion. Any help would be appreciated greatly.
Hehehe. User Error
For anyone facing this in the future, the ribbon connector at the top of my digitizer was bent slightly, as it could not sit flat because of two of the little rubber bits near the top. Remove rubber bits (like the manual tells you too ) and refit the digitizer, then refit the rubber bits and continue reassembly. Fixed
I feel so stupid.
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

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!!
Hello, guys!
Recently I bought an HTC One with cracked digitizer, but functional. It had a lot of scratches etc, but this is not important right now. I wanted to do a complete make-over so I bought replacement parts from the internet, I bought the front housing with the LCD screen and the back cover. I dissasembled the phone from the old housing (the one with the broken digitizer), and I assembled it back on the new housing. After all of that, I powered on the phone and it worked like a charm (the LCD and the touch-screen worked perfectly), but then I saw that the glass was a little out, I mean it was upper than the speakers cover, so I decided to take out the whole screen and to change the adhesive, because it was too loose and the screen wasn't staying properly. I succesfully did that, i put the screen back and everything was good, but when I wanted to start the phone, the screen remains black. And this is the problem I have. I mention that I worked very carefully with the screen, so I don't think the problem is at the screen. I disconnected and reconnected all the cables and still doesn't work. When I press the power button it vibrates and then it's making that sound like the phone is booting, but no image on the LCD. If I keep the power button pressed, the back and home buttons are blinking and then the same story as before, vibrates and then the sound. I really don't know what could be the problem.
I really need some help with this and I'm open to all of your suggestions. If you want more informations feel free to ask.
Thanks in anticipation!
To me it looks like you damaged one the flat flex cable.
When you took the screen out did it come like suddenly and maybe some tension was applied to the flat flex?
If I were you I would take it apart and verify the connection in the socket, maybe the socket was damaged or something and it doesn't make a good connection
I hope it works out for you
Thank you for your answer!
When I took out the screen, I took it out very carefully and there wasn't any tension applied to the flex cable, so I don't think this is the problem. I think it's more likely a problem with the socket on the motherboard, like you said, and it's not making a good contact. But what can I do about that?
Sorry if this is the wrong place to post or it's been covered already. I have a p9 stock that I changed the screen on after dropping it. Everything was fine until the new screen started to fail, it was a cheap eBay screen and the glass started peeling away. I fitted a new one and when I switched it on the backlight comes on but no image, backlight then flashes 5 times and then stays on. The phone does the one vibration like it's starting up but after that does nothing. I tried the reset procedures but doesn't help. It wasn't on USB debug so I can't connect with my pc. I first thought the screen was faulty so had the vendor replace it but still have the same problem. Could it be the main board has been damaged or the flex cable?
Sounds like a batch of bad screens. I would stay away from eBay when it comes to Huawei P9 screens, too many issues with them. Had ones that were refurbished or glass separating from the screen frame.
Buying it without the frame and applying the adhesive yourself seems to work better for me. Anyway hopefully you didn't kill the backlight circuit on your phone.

Backlight seems to be fine. You could be right, there's a faint blue tinge in one area.
Hey, did you ever solve this? I have the very same problem
