My touchscreen won't work. - 8125, K-JAM, P4300, MDA Vario General

I've done everything I could do without taking apart the phone.
I don't know what's wrong, sometimes it will work sometimes it won't.
Now though, I reinstalled WM5 (latest cingular build) and I have to tap the screen to start using it, but the screen won't work.

that happened to me when I put a screen protector on my phone. I took off the protector and the phone worked again

I dont have one of those.

Has the mobile fallen on the ground? Make sure the screen doesn't have any dust on the borders... if there is contact on the screen on any point, it won't recognize any other point of touch (multi-touch is not supported by our screens).

I'll try cleaning that out when I get a can of compressed air

I got it to work for a second so I can use the phone. Now I just want it to always work.

Thanks so much for this post!!
The other day my touch screen stopped responding to my taps.. The lcd worked fine and I could still navigate with the buttons, it just wouldn't respond to touch..
So I was almost ready to take my phone apart to see if the digitizer connection was loose.. I decided to search around and see what other ppl had to say about TS problems.
I read this post and started to go around the edges of the screen with a business card and lo and behold it started to work again.. Must've just been some dirt up in there.. You just saved me a huge headache!
Thanks dferreira

My screen is all white now.
Anyone know how to take apart the phone, I'm thinkin my ribbon is not connected right.

Touch Screen Malfunction, need HELP!

Good evening... Well recently, i bought a Screen Protector from ShieldZone for my hermes. Well I applied it to the screen and so forth to the rest of my device, then i realized the touch screen doesnt work. I take out the battery for a few minutes, and it starts to work, but after a few seconds, it stops working again. Any suggestions?
This happened when i put my first screen protector on too.. What happened is you put the sticker on to tight; there is an equal pressure over the entire screen , so the processor cannot distinguish your pen touch from the rest of the matrix. All you have to do is take the protector off and reapply it with less force and it should work. (It took a few tries on mine to get it right, did the same thing on my wife's Treo 750.)
well,sounds strange,did you align the screen properly??
Im using a not so costly screen-protector on my hermes without a problem.
Probably u may remove the shieldscreen and make sure dat its not a hardware issue,good luck
yeah i took off the screen protector and still i have the same problem. Anyway i can change the pressure settings?
well,Im not sure about pressure settings but you may try re-aligning the screen (in settings) ,it shud help mostly,hope u have warranty which is not void...
I had the phone unlocked, and I put in the latest Cingular OS, even though i am on the TMOBILE Service.
I have the wierdest thing happen this morning!!! I woke up and turned on my phone, and there is a little smudge in the center of it. Almost like there was a air pocket between the protector and the screen, so i took the protector off, and it was still there!!!!!!!!!!!! So, i pressed down on the little spot and it moves around just like an air bubble would. I turned on my phone to see fi there would be any problems and for some ODD reason, everytime i tap the screen it smushes in that spot. It looks like when you press on the lcd screen of your computer and the pixles kinda move around a little!
Was wondering, I have a Cingular 8525 and would this warrant a repair? Meaning, Could I call them up and tell them what happned and they would send me a replacement?
This is really getting frustrating... I had this phone for only 8 days and its already giving me a headache.

HTC Shift Touchscreen Problems

Has anyone had problems with their touchscreen not responding to their pen or fingertips? I received my Shift a couple of days ago and I have tried everything that I know to get the touchscreen working. Called support, but they had no solutions as well. The funny thing is, that when the computer first boots, after I enter my password, I can control the cursor for a couple of seconds and then it loses all ability to pick up my movements and taps. Also, when I reset snapvue, I can move the scroll bars but cannot double tap any icons to launch. I am sure it is some sort of software issue, but I have limited UMPC experience.

I had the same problem. I had put my screenprotector the wrong way.
So, try to take of the sheet. Maybe that may help!

Isnt that just classic, I didnt know that you could put a screen protector on the wrong way. Well theres a couple days I wont be getting back. Out of curiosity, what is the right way to put the screen protector on? Thanks for the response - all is well, except for my slight embarassment!
Hmm... a screen protector is sticky on one side, and not on the other.
How do you put it on the wrong way?

Touch screen not working

I'm sorta new and not exactly sure how to submit questions.
I installed the SPB mobile shell on my elfin htc and now the touch features don't work and my phone won't sleep without what appears to be the backlight on. Can someone provide some directions on how to fix this? Can't get to the bootloader either.
if you reset your device, can't it boot up into windows mobile?
if it boots up, why not connect it to the pc and try removing the last app through activesync?
if there isn't anything that important on the device, did you think of a hard reset?
Thanks for the quick response, however, I did do a soft reset, the screen is not responding (completely frozen). I've already removed the program, I thought was the culprit (spb mobile shell). I did a backup, but without touch features, I can't restore backup. I can't do a hard reset that's not working properly either. Any additional ideas, I'm at a complete lost.
Hi
Touchscreen of my HTC Touch (P3452) stopped working. I tired following:
- hard reset
- hard reset successful, then It asked me to tap the screen for alignment then I tap, it worked but on Calibrate screen where you align your screen touch is not working. nothing is happening after that even power button is not working. my Touch is not hanged coz if I touch the screen after It goes to sleep, the backlight will turn on.
So I though may be something wrong with the original ROM, then I tired flashing it with cooked ROM's but nothing worked.
I am still stuck at calibiration screen
-
Plz help, I miss my HTC Touch (P3452) so much!!!
If your touchscreen is not working, there could be only 2 solutions.
- Get a digitizer off dealextreme.com
- Hard reset device.
my $0.02.
Cheers.
What's a digitzer and what does it do? I've looked in cell phone accessories and did a search on dealextreme.com, however, unable to locate such an item. Can you provide a little more detail. Desperately trying to get this phone to work and right now this appears to be the only solution. Hard reset isn't working.

Come on, Google man!
http://www.dealextreme.com/products.dx/category.506~search.htc touch digitizer
Digitizer is a 'panel' which is above the LCD, which senses where your hand is at on the phone.
Something like this:
http://en.wikipedia.org/wiki/Graphics_tablet
It is just something which sense where is your fingers are in the touchscreen.
Hi toot-b:
I had a similar problem a few days ago. My screen stopped working completely. I gave it a few taps and a squeeze and it started working.
After a while it stopped working again and did not respond to the squeezing too. Then out of desperation, I tried searching the internet. One guy had given the most idiotic explanation I've ever come across.
He had advised to take a blade and peel away the LCD screen and after taking the screen away, to rub the copper contacts with the blade and then putting it back in!!!
Well, I was really really desperate and I had to try it. I didn't remove the screen completely. I just took the screen off a wee little bit on the bottom right corner near the camera button. I kinda got scared after that and put it back in.
To my surprise, the touch screen started working perfectly and till now its doing great. Try it at your own risk. All the best!!!!

Major touch screen problem with touch hd!!

touchscreen was working today morning, took battery out for 2 hours, turned it back on and it was working abit weird, and now i cant press any touchscreen buttons atall!
So no softkeys (pick call, home etc.) and nothining on the big screen! I can turn on the phone, press the power button and volume buttons, see my home screen get calls etc.. hard reset twice, took battery out, nothing does it .. gonna try flash it but dont think itll do it ... and ideas?
Im in uk aswell if that makes a diff
Dear All,
I have similar problem. Usuallí I use on my HD NRG ROM. About 3 weeks ago I updated to the latest NRG WM 6.5 23xxx ROM with Sense 2.5 Maxmanila version, and since this upgrade the touch screen position moving randomized up or down from 2 mm to 30mm!!! After this ROM I tryed updating each newer version, but not changed nothing. I need realign the screen about 10 times / day!!! The phone I never dropped or cracked.
Can help me somebody what happened with my HD?
I had this happen to me yesterday. I was surfing on my phone as per the norm. Put my phone down. Got a txt, picked it up and it wouldnt allow me to access it. I thought it must be a freeze as it has happened occasionally.
So I restarted.............and nothing. No response AT ALL from the touch screen.
I have noticed the oily spot problem on the most part of my screen, and thescreen doesnt have that little give it used to when using it (paranoia possibly)
So I can only assume something has given within the screen. Ive been searching all day on the internet for causes and fixes but nothing has come up.
The volume and power buttons work but I cant do anything at all with the phone as its obviously all touch based.
Is this a screen replacement job then or is the whole phone goosed?
Roheelshah if you turn your phone off do you have the massive oily screen thing?
Any help is most appreciated....
I had the same thing, a oily spot, but it was there for months, then i noticed another new spot (looked like a tiny tiny burn) and thats when it stopped working completely... ive ordered a new screen which should be comming in a few days, im hoping thats the issue
will let you know if it works ....
keep me updated if you find anything
thanks!

whats it do? and where from??
I just posted something like this a few days ago, pulled my phone out and screen wouldnt respond, had these marks all over my screen, "swirly marks" as i describe it, very well could be the oily marks you are talking about. you can move them around with your finger right?
anyway, i took my sim out, tryna find a spare phone, couple hours later the marks were gone and screen started working again, touch wood its been fine since.
no idea what happened, but try letting it air out or something
ok basically i received a new digitizer today (the actual touchscreen) ...
i dismantled the whole phone using the service manual and some video some guy made (VERY HELPFUL, if anyone wants it for any reason i can post a link), ok so i got rid of all the top bits, the circuit boards (or watever theyre called)
I got down to just the bezel, lcd and digitizer (dont know what a bezel is, the lcd is where the display actually is and digitizer is directly stuck ontop of that)
Apparently when replacing the screen, htc have made it so that you have to replace all three of those parts instead of individual ones, but you can buy them seperately so i thought i'd hero it.
i poked out the screen from the frame (some chewingum like stuff holding it in) then i started peeling off the digitizer (if you get one and want to try it you'll know where to peel) ... this was a mistake tho cause the lcd is unbelievebly sensitive so while peeling off it left scratches on the lcd, and me not knowing the lcd is sticky tried to wipe them and use a dust free cloth, which left alot of crap on the actual lcd!
i managed to get the digitizer off and ripped the cable that goes from digitizer to whatever reads our fingers on the screen, took it all off, placed the new one directly ontop and fed the wire exactly how it was for the first screen.
Put it all together again
Now I did mess up my screen badly, but in a good way! .. i now have full touchscreen working (smoother than ever) but my LCD display is near enough gone, so it looks like the screens really really dark, and i have to tilt it at certain angles to see the screen..
After all of this i now have a touch hd i can controll from my pc (using mymobiler) so i can recieve calls, send texts all from my pc when connected thru active sync, can even play teeter ... but not really the same!
I wouldnt recomend anyone to try what i did, although i think its worth the risk as I would have to replace the lcd anyways if i wanted a new screen in the first place... and who knows you might be able to peel the digitizer off clean (NEVER EVER EVER TOUCH LCD WITH ANYTHING!!!).
It all cost me around 10-15£ for the digitizer and screwdrivers and alot of hours dismantling phone compared to 50-100£ for a new lcd.
I am either going to get a new lcd now so i can actually see the screen, or get a new phone.
Sorry for the essay but hopefully this helps someone in any similar situation
if i do get a new lcd will post how it goes and if it sorts out everything
if anyone knows of any other reasons why my lcd would be so dim (brightness is 100%) accept for me getting carried away with it ... help would be appreciated

Yeah swirly oil marks is how myne started ... i think i finished off the screen by trying to press hard on the mark to try and clear it .. . so be careful with it.. but think that overall the screen had seen better days (course only a few weeks after warrenty finishes) ... all conections inside were ok aswell

Same here. Touch screen not working. Phone never flashed, droped,...
Any solution?
unfortunately, a friend of mine changed the touchscreen without success. Phone was in perfect state, no drop, no flash. Just the touch not responding. I'm not sure that changing whole part lcd+digitizer solve the problem.
Hi all!
I've got similar problem with my touch HD. It's stock since I bought it. My touch sense was acting weird, like it wasn't properly calibrated. Like, when I press 7 on phone pad, the phone actually presses 1, and if I press 0, phone presses 5 and so on..
I've tried to align the screen, but it doesn't get aligned the first time. I have to repeat the process about 4 times before it gets aligned. That's good for about few minutes and the problem is back. Hard reset was also done, 2 times.
Could this be a fixed with a software update? Does this mean that digitizer will soon be dead?
Thank you for your help
Regards

Just did the hard reset. When it asked me to align the screen, I just couldn't align the top left corner. I had to press it like 50 times before cross went to the lower corner. Otherwise, after the align it's good for about couple of seconds and then it's just pressing all over.
I thought I had just some software issues because the screen wasn't dead, it responded to my touch. So, I'll probably have to buy a new screen and digitizer, right? Or do you have any other ideas?
Thank you again for your help!
Regards
firstly screencal installs calibration settings not for blackstone so do not install it, no point. (btw it also increases device touch sensitivity)
secondly you guys should try and install the calibration settings for blackstone, basicly what the align screen does, not sure where to find them for download but i could post the registrys if someone wants to make a .cab from them. (atm i cba making the .cab but i am able to do it )
if the calibration settings do not work i think it is best to buy a new lcd package (or buy new device and give me old one for spares oj)
Rn
hi buddy ! What you mean GSensorCalibrator ??
i didnt mention anything about gsensor calibration dude.
tried and tested screencal the other week and it screwed my blackstone.
install these instead:
*screen calibration, sets the blackstone touch points: (aligning the screen)
if you install a cab with these registrys it should fix the alignment problem.
(if it doesnt then its hardware issue = lcd etc)
[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH]
"MaxCalError"=dword:8
"CalibrationData"="511,542 183,881 183,198 834,197 833,880"
*this one will maximise the touch sensitivity for those that want it:
[HKEY_LOCAL_MACHINE\Drivers\TouchPanel]
"PressureThreshold"=dword:0
Rn
Does anyone have a recommendation where you can buy a digitizer and lcd from?

[Q] Nook touch screen not responding

Hi,
On my rooted nook touch, sometimes the touch screen stop working.
It appends whatever software i'm using and randomly. Buttons works, page refresh works too and the nook doesn't lag, it's just a touch screen crash...
I tryed to unregister the nook and to update it from 1.0.0 to 1.0.1 then root it again but the problem still here.
Do you know a solution for this problem ? each time it's append I must hard reset the device (power + right bottom buttons)... is there a service to restart to enable touch screen again ?
Thanks
Hi, I'm new here ^^.
I bought the nook touch 2 months ago, and it worked perfectly until yesterday. I installed MSN Mercury from the market, I logged on my account, but when I clicked the menu button, the touch screen stopped working and I used adb reboot from my pc to restart it (I didn't know how to hard reset).
It scared me a lot, and I uninstalled that msn when I restarted the nook.
I request a solution for this too, and, do you know a simple MSN that works perfectly on our e-Ink nook?.
PD: Sorry for my bad english ^^u
Same as you.
Just screen is out of response.
Happened both 1.0.0 1.0.1.

Long thread about the subject.
From the thread and running into the issues myself, it seemed to be a sensor/dust issue as the only solution I found working is wiping the screen with a cloth or so. This is kind of sad since I already has a screen protector on it but I guess any bit of dust on the screen could cause the touch function to fail.

I do not have much faith in the dust theory, you'd need some serious dust, like sand, on your screen for the sensor array to even notice it
Remember, it's not a touch sensitive screen like those on phones and pads, but a rather coarse infrared grid "above" your screen.
I've experienced this once myself, and then I simply put the NST away for the night and when I woke up in the morning it was working again which makes me suspect a lockup in the driver,
Had this happen to me. Here is the timeline
1. Girlfriend bought nook for birthday
2. Dropped said nook after 2 months or so
3. Bought refurb off ebay from B&N's ebay account
4. Screen would stop working randomly
5. Contacted support
6. They shipped me a refurb replacement
My second nook wasn't under the extended warranty or even a 30 day warranty. Its a manufacturing issue so they should replace it for free.
Ok, so I had this same problem, and took it to B&N, they said that they hadn't seen that before a gladly replaced it for me. To this day I'm still not sure what caused it, but I know it happened after leaving it in a pretty how car, but not sure if that's linked or not. My current one which I've had for about 5 months hasn't had any problems.
Old thread is Old but I'd gotten mine knocked out of my hands. Screen looks undamaged but the hardware buttons don't appear to do nything other than holding down the n switch to make the glowlight come up. Tried putting it to sleep, plugging it into a computer. Only thing that seems to indicate it isn't a total brick is the glow will come up. Other than that screen has a static of the last book I was reading in coolreader.
Bought the thing for an easter preasent to myself from walmart. Still have the box but it's rooted and til the drop had no problems whatsoever (well problems that weren't due to user error.) Saw a 'leave it overnight' suggestion and am going to ttry that.
Is there anything I can try or is this going to be one of those 'the outside looks fine but the slight bump wiggled something loose that you're going to need to tear the whole thing apart to fix.' things?
Edit: failing that could someone walk me through the button presses/times to press each button to un-root/restore backup using NookManager? I'd be doing that blind as the screen only shows an image from coolreader but I figure better to try taking it back to stock before returning even if nobody looks it over.
Hi All,
Solution for screen as simple as... get tissue, dump it with a bit of water (tap water will do) and clean your screen carefully. Solved Make sure that water gets into corners of screen. There is some kind of filter. It must have connection with top of the screen... some how water do the trick. I was designing custom cover/case for my nook when I discovered it. BTW your finger shod be a bit wet when you use your nook.
Hope it helps!
Thanks

The Nook doesn't have a capacitative or resistive touch screen, so having a wet finger is irrelevant. Instead, it uses an infra-red touch screen. Between the screen and the grey plastic bezel, you'll see a transparent lens protecting the IR emitters and receivers used to determine finger position. Reportedly, if that gets dirty, it fails to register finger positions.
