Diamond touch screen not reacting when touched.

The touch screen of my htc touch diamond is not working properly. It does not react to my touch. For me to get it to work I have to rub my fingers over it then it will be work again as normal. This only lasts for a few minutes after a while it becomes non responsive again. It is like it has to be warmed up to get it to work. This a problem when it comes to sending text messages. (the problem remains when I remove the protective screen).
Anyone has a answer to this?

remember the last program you installed and remove it , maybe it cause this problem
or try hardreset

Tried both methods still not working. I have ran out of ideas. Anyone else expierenced this problem?

Im having the same problem with my Raphael

To really know whether it is a hardware problem or software based problem, I recommend a hard reset and see whether the problem persists...

this is likely to be water damage on the screen. send it off for warranty see if they fix it. they fixed it for mine.

The thing is iv noticed the touch screen isn't thermal reactive like most touch screens. In other words the temprature of your finger is sensed on thermal screens, the HTC you can use anything solid that makes contact. Usefull if you have long nails.
So I'm guessing its probably hardware if it works after a while of 'rubbing' it, But like otacon said I would do a hard reset before jumping to that conclusion.

Same problem
Hi there....i saw that this is an old thread but did you manage to get it to work?
Cause i have a HTC Diamond that i changed both the displays on(LCD and the "point screen") and everything works fine on mine now,even tried to recieve phonecalls and it works excellent so as i said EVERYTHING works like a charm but the touch function.....it doesn´t react in any way while trying to use the touch function and i have tried soft reset,hard reset,new rom,checked all the internal connections around 4-5times and everything is ok but the damn touch function won´t work whatever i do with it.
I haven´t "glued" the 2 screens together,but they are sitting close to eachother so it should work anyways right?
Now from what i have seen on internet is that there are different versions of touch screens available on the market and i ordered the LCD from one company and the touch screen from another.
Could it be so that they aren´t compatible together or am i doing something wrong?
I´m still stuck at "Tap the screen to set up your Windows Mobile-based device" and can´t get any further after trying another rom.
Please help me out if it´s possible.

I have exactly the same issue you're experiencing, I've actual flashed the original rom, thinking that might put every settings in place to make it work, but no joy.
I don't be leave the concept of the weather condition equate to the performance of the device, as read in some of the forums. reason being I've had mine in very hot climate Country for over year whiles working on a project in Africa. In fact that was when I realised the the screen has become unresponsive.
I think this is a hardware issue.

It´s working perfect again
So since my last reply i ordered a new touch digitizer and lcd display and soldered them together carefully(first time i bought a lcd and digitizer from two different companies so they weren´t compatible with eachother and made the touch defective and second time i bought both digitizer and LCD screen from the same company and then it worked) and it has been working perfect since i last wrote my comment so i recomend you check the contacts/connections first on the phone because i had some minor issues with them when i assambled the phone again so i had to #wiggle# the contacts so i made sure they were connected.
We had a company here that sold lcd displays and digitizers out for a total of 30dollars with shipping so i had nothing to loose on it so that´s why i ordered a new set again and that made everything work as a charm since i replaced it.
Now i have searched online about the displays and the digitizers and i have found out that there are atlast three different versions of them so if you order a digitizer and a LCD make sure you atleast order both from the same company so it doesn´t happen the same to you what happened to me the first time.
Cheers and hope i helped you somewhat or else just ask on and i should try to answer.

Mega touch screen problems on x1

Hi Guys
I've been having some serious problems with the screen on my X1, most of the time now the screen doesn't respond to me tapping it, alignment is a waste of time.I'm wondering is there something I can do to fix it or will it simply be a matter of returning it. I'm in my last few months of a 18month contract and based on my recent experiences I doubt I will be getting another x1 (or even x2)
Thanks
Simon.

Exactly whats happened to mine! Its my 3rd X1 now and O2 cant (wont) fix it. Its a terrible phone. I cant use it now and you know what, I dont care, I would rather have a Nokia 6310.
Ive had every problem going and Im careful with my phones. First one the screen died when opening, second one no one can hear me and now this. I have also had the usual cracks issue on all 3 phones. Even when the phone works the reception terrible and it hangs all the time. Never a sony Xanything again.

Alignment problems and touch screen problem
I just updated my X1 last week ( 02/17/2010, my phone it's 1 year old with no problem at all, before this ) and everything was OK. Then on sunday the screen wasn't aligned, and I started to aligned almost every hour. Then I realized that after sliding the keyboard, the touch screen was death (not black, but doesn't work the touch function) for about 40 seconds, and after that it works again ( opened and Landscape). I also need to align the screen very often.
Before this happend, I never aligned the screen, only when I updated the X1. Also, on last friday ( before the screen problem ) I installed the Youtube aplication for the X1, and gave me problems because it doesn't have a Landscape screen, and the X1 crashed when I slide it, then I had to reboot it.
After this problem I started to have problems with my X1 ( alignments and death touch screen with keyboard opened )
Does some body have an idea to solve the problem?
Im sure this has to do with software or advanced settings like HKEY config.
Thanks in advance.

i have the same problem
but now, the problem is horrible
the alignement doesn t accept
when i touch the down list (call, contact etc...) the xperia open the Start bar
arggg

and it returns to normal after a while
what could cause this problem
i flashed many roms, with same result

It's not something either of you installed, but your hardware - either your digitizers are on the way out or your flex.

its hardware
yes, i can say its hardware. I have repaired many of them now.
Most of the time when its black/no touch screen response its the flex cable.
somehow the cable damages very easy when opening/closing it.

Have try this?
1. Use a registry editor
2. Navigate to or search for:
HKLM/Drivers/TouchPanel/PressureThreshold
and
HKLM/Software/OEM/TFLOSettings/FingerPressure
(eg search on "pressure" and you'll find both)
3. Edit the values to any VERY VERY high value such as 999999999 (nine 9s)
*** CAUTION: do NOT change either of these fields to anything less than about 2000
because if you go low enough you will make your touchscreen unresponsive,
at which point it's tricky to change it back (learned the hard way)

Do I welcome aboard?
I have the same problem now and before I read this thread, I formatted my X1 cos I thought that problem was caused by software. Now I am sure it's about hardware. Have to open it soon

are you sure it's an hardware issue?
for me it started today after hard reset...too bad!

Well screen problems in Xperia are mostly caused due to the loose flex cable. Mine had the same problem. At times the screen would work and sometime the screen would not appear. But if you want to open your X1 and have a go at it yourself then do so.
I managed to fix my flex cable without causing any damage *phew*
If you have nothing to loose then give it a try and see if you get lucky.

[Q] Diamond touch display doesnt respond anymore(after replacing LCD and touch panel)

Hello everyone.....i have recently changed my broken LCD and touch display on my phone and everything on the phone works good except the touch function.
I have checked the solderings between the LCD and touch panel and everything is ok,i have also checked the connections and they seem to be good and the display itself works with light and "pictures" or what we should call it.
Before i reinstalled the software i could use the buttons and navigation button underneath the touch display and power button/volume buttons also worked and i could even recieve a phonecall with it.
I checked so the tilt function also worked and the wifi etc.etc as i said EVERYTHING works like a charm except the touch display.
Have anyone else had exactly this problem with their phone after replacing the LCD and touch panel?
I have checked all the connections inside the phone atleast 3times now and i´m getting abit tired of disassembling the phone just to see that everything is in it´s right place.I have tried with different roms from HTC:s website also without any positive results.
I searched the forum for exactly this problem but couldn´t find anything similiar to this to get the touch to work so i´m sorry if it´s already "out there" and sorry for my "laggy" english but i´m from sweden so i hope you´ll understand.

Ok guys don´t bother....i managed to fix it on my own anyways!

Grattis! What was the root cause and your solution, eventually?

Yeah sorry i forgot to also tell the actual problem.
Well tho everything looked ok,the problem were caused by a incompatible digitizer and screen cause i got them from 2 different places and they simply didn´t matched up together as one unit.I just bought a new lcd so i can have the old one as spare cause the lcd screen worked fine but not the touch digitizer and i also bought a touch digitizer from the same company.What i have been noticed looking around on "the web" after i got this "problem" was that there is alot of different versions models and i probably got unlucky and got myself a mismatch.
On the other hand the lcd and touch digitizer was like 30bucks(338SKR) on a swedish site called "Teknikproffset" so it was well worth the money to just order new "proper" things that matched up.
Hope this answer your wonders and if it´s something else you wanna know,just ask
Hade göttans.

I see. Tack foer svara!

[POOL] About the touchscreen problem

I only discovered the touchscreen issue yesterday doing the test of the other thread. So, i would like to every z1 owner to answer this pool to know how bad things are and if we can try to find a solution, since i think Sony won't.
So, please answer the poll and post any useful information. I'll start.
My phone model is C6943, I currently don't use case and I'm using a screen protection. I can do the xperia touchscreen test without touching the phone body without problem and also doesn't have problem with pattern password.

Pool? I think you mean "poll"
My 6902 is completely screwed. At first I used a screen protector and the problem wasn't too bad. Then I removed it when I took the phone in to get another issue fixed and soon after that the problem got very bad. I was traveling so couldn't go back to the service center. Now it's a bit better, randomly works and randomly doesn't. When I was home in cold weather though it seemed a lot worse than it is now that I'm back in India where it's warm. Not sure if temperature is a factor, or could be conscience. But a few weeks ago it was so bad you couldn't type even a two letter word using Swype.
Also, I now have a part of my screen in the form of a horizontal line where touch doesn't work at all. No single touch and no drag. Completely dead. Taking it to the service center soon.

You should vote on the first option, then

Guys, check my post "News from whats is causing touch screen problem" to see if is your case!

It's not.
I got problem unlocking with patterns, scrolling pages and when I play some games after few minutes it stop working so I voted the first option. My phone is back to Sony, I hope they know what to do and at last it's Made in China.

Please, post if you use case and screen protections too. This could help understanding the problem.

Additional data : Z1 is being handled in a leather case, back and screen protector removed ( not the one with the logo, the plastic ones that makes your camera blurry )
Touchscreen problem seen in the game Alien Shooter, after some playing, the touch screen becomes less and less responsive ( i tap a button to shoot and use some onscreen joystick to move ) - both become unresponsive/less responsive as you play and the phone gathers some heat ( you can feel the touchscreen becoming hotter )

i have a simple tpu case, i had a bit of problem when playing all touch-based games (not ones with gyro like asphalt).
ever since i got the case it's better, i have the ASF and nillkin matte screen protector

I did not use any case just a chip screen protector. Anyway on a good healthy touch screen the screen protector should not influence the touch screen respond.

Hey guys, I have also this touchscreen issue, and I would appreciate if you give a feedback about warranty service, if sony accepted the problem and replaced a touchpanel or not, and also if the replaced touchscreen is better or not. I´m also thinking about sending it back for warranty repair.
I have also found that my phones touch screen is temperature sensitive, when it get cold or warm it just refuses to detect touch actions. Try it yourself put the phone into cold/hot water for 5 second, take it out, quickly clean the display from water and test the touchscreen. I first tought this behavior is normal and I didn´t cared until I started to play games. After 15minutes of playing the touchscreen bug every time appears. But also after a while its randomly disappears. So this thing is strange. (the bug appears identically also when I have my phone in a plastic case)

For me the warranty worked perfectly, i changed the phone 3 times until get a working one, i called Sony, discribed my problem and they changed for me, only 2 days for the change. BUT i recorded the problem and sent to them, so they accept the change.

Same here. I sent my phone back last week to the store where I bought it 2 months ago. They will send the phone to Sony Center but the time for repair or replace the device will not be 2 or 3 days but from 2 weeks to no eta. When the phone will come back to the store they will send the phone to me. I will post if the problem persist or not.

The problem is if they return a phone with the same problem.

They should be aware about this issue even on the new device so at this time they probably will check that but if they return a phone with the same problem, I will send it back again like many did. Someone had to replace the phone 3 times and I will do the same.

IYeah, you will be a long time without your phone though. I think I'll wait a bit since i rarely get the error and actually only when i try to reproduce it. How bad was yours?

I was able to reproduce the problem in many ways, Touch Screen Test, Opening the phone with Patterns, Scrolling Pages or with Launcher instead of switch the page it was opening the applications and at last when I was gaming at one point the touch stopped working and I had to wait, so this made my mind to send it back. On daily use was all ok but in some circumstances was frustrating.

i had the problem with cm11. and when I retored to stock then the problem was gone:S

I'm on stock and I got the problem.
Today for the first time I got the problem when writing on handrite. So I thought about using my phone warranty to get anotehr one. But it don't always fails when i do the method to reproduce it. So, how do you test if your new phone is working and how do you prove that it isn't? I mean what if i take the phone to warranty and it works?
And for you who already changed phone, it is working?

Sent from my C6943 using xda app-developers app

Did youu made the method to reproduce and it didn't failed? For how long do you have the 3rd phone?

[Q] I have replaced my screen twice but the touch screen stops working after 24h

Hi friends,
A week ago I decided to finally replace the cracked screen of my phone. The phone was perfectly working, with the exception of the annoying lines everywhere around the broken glass.
I went to a repair service (not official) to have it changed for a new one (glass+lcd) and got it back repaired after few days.
During the first hours the phone was working just fine, but I noticed that the touch screen was slowly getting erratic. After few hours it was just a bit erratic but ok. 10 hours later it was almost impossible to use already. 24 later it didn't respond anymore to the touch.
I went back to the repair service and asked for a new screen that I got for free because we assumed it was a problem of the new screen. Problem is, it happened exactly the same with the second one!! And now, 24 hours later, it doesn't work anymore.
I have done a factory reset. I have flashed new ROMs, I have flashed back to the stock ROM, updated it, nothing has changed so it totally looks like a hardware issue.
My question is:
What may be causing my new screens to go mad after working perfectly fine during the first hours?
Summary:
My Moto G 2014 works perfectly, but it has a crack in the screen
Decide to go to a non official repair service to have it changed for a new one (LCD + Glass)
First hours with the new screen: All works fine
Slowly, the touch screen becomes more and more erratic
24 hours later the touch screen is useless (it still reacts to touch but totally mad and weak)
Decide to have it replaced again (this time for free)
With the second new screen, we test that works fine, and to confirm that is not the phone, we install back again the first new screen, verifying that it doesn't work.
Finally install the second new screen. All seems to be perfect!
Experience again all the previous points
What should I do lads? Did the repair service **** my phone? ;^(

It could be that water somehow got in (speaking from experience).

How would that explain that the newly replaced screens work fine for the first hours and then gradually stop working?. Also , I can't imagine how water got in the phone for the last weeks, besides, it works perfectly, is just the touch screen.Water would most likely **** more things. no?
Has anyone experienced the same problem as me?
thanks!

Is it genuine?

The screen? I don't actually know. But after changing twice the LCD seems unlikely that the LCD was defective. It may be more related to my phone (although I can't understand what) and something the guy of the repair service ****ed.
Any thoughts?
thanks for the help
