The screen on my xda exec stopped responding to taps. It seems that the touch screen ability is gone. I can use the keyboard fine and I've done a hard reset. Does anybody have any ideas on how to fix this?
Thanks.
I had the same problem, send it for repair. And the same problem reappeared 2 weeks later.
So I tried to find out what the problem was and thanks to this post I solved the problem;

It's not really that weird: If some dust, or something equally small gets between the screen and the plastic frame, it can put enough pressure on the screen, and so the touch screen takes it as a constant (or intermitent) input, invalidating any other action on the rest of the screen.
And this is exactly what happens, try to clean with a thin paper between the plastic frame and the screen.
It solved all my problems, now every once in a while I get the problem and once cleaned it works again perfectly.

Thanks. I'll try that. Fingers crossed!
The cleaning did not cure it. Took it to a repair shop. They said the LCD and touch screen are fine. When he tinkered with the flex cable (disconnect and reconnect), it will work for a few minutes and stop. Does anybody know where I can get this specific part? Is it really the cause of the problem?

It seems that as of late I have to re-align my screen almost on a daily basis. It will be ok vertically, but horizontally it seems that it's always shifting.
Has anyone else ran into this?
Yep, I've run into it. Sometimes it can go days without having to realign it, other times I have to realign it every 15 minutes. Seriously. I thought it might have something to do with opening and closing the keyboard but it's been hit and miss so far. I can't prove that it and I can't prove that it isn't. Sure would be nice to figure out what it is, however, and have it fixed.
How do you carry your phone around? Do you keep it in a case on a belt clip or do you keep it in a front pocket of your pants? If you do not use a case then try it for a few days and see if this helps with the alignment problem. (Body heat and/or pressure on the screen may cause the alignment to drift.)
This is a know hardware defect. It should be covered by your warrenty. T-Mobile exchanged mine with no problem.
Mine had the same issue but it hasnt been an issue since the 2.26 update on Tmo.
I had my phone replaced and it's still having the alignment issue. This sucks bad. Realigning and resets doesn't help!

Getting rid of magic button and vbar, if you run those apps, did the trick for me...I switched to wisbar desktop and ever since I have not had to realign my screen once in 2 months
I'm going to try this out and let everyone know. I'm having the terrible screen alignment problems (I at first thought that it was the keyboard and switching landscape mode) but I have magic button installed. Going to try the switch to wisbar lite and see if that helps. Does anyone know if the business card trick for the hermes will help with this?
I think it is a hardware defect, i have problems with mine, not only i have to re-align it often, my screen is also not responding to touch either. (from time to time).
Not to respond right away without extensive testing, but I did just put on wisbar lite and noticed a definite improvement in aligment (certainly seemed better than magic button) someone else should try this too and see if they notice an improvement.
I was having this issue for awhile. The card trick had helped on my previous 8125 but not this time. Carrying it in the case instead of my pocket seems to help quite a bit. The issue also seemed to be affected by pushing on the plastics around the screen so that might be a clue right there too.

Sounds similar to my fix of pushing on the plastics all the way around. I haven't really had this problem since I did so and I have only had to realign it a couple of times in the last few weeks.
my phone's alignment used to get screwed up multiple times a day.
I took the stupid stick on screen protector off it though and haven't had that problem nearly as often. I maybe realign once a week, and when I do, it's only because it's off just a bit.
I had alignment problems frequently a few months ago but it is all history now.
1) Fix current alignment problem.
Just make sure you confirm if it is a hardware defect first, by checking the tiny gaps between the touchscreen and the casing for dust particles. Use a high power scope(I work in a semicon backend company so no problems getting one). Clean the gaps all around the touchscreen. See if that fixes your alignment problem. If it does, then probably your screen has some electronic problems(claim warranty).
2) Protect your screen from pressure at ALL times except when you use it with your stylus or finger.
I carry my Wizard in my pocket with a plastic transparent plate covering the entrie screen(ala HP's RW6828 forgot that model already).. Have been doing this since last year and no alignment required since last year...
Just wonder why HTC doesn't make it an option of have the protective screen on their devices... Beats having a bulky casing..
Permanent fix for Alignment problem in 10 seconds
Well I read many posts and finally came to the conclusion that the best and permanent fix for the alignment problem is as under.
Slide out the keyboard, you will find 2 screws at the back. Loosen them and then retighten them but not as hard as they originally were but lightly.
Presto
Problem solved.
U will never see your screen misalign again.
Thanks
software problem
The original Cingular wm5 rom had this alignment problem, I flashed NBD's WM6 v5.1 rom and it was fixed. I tried other wm6 roms with mixed results, some would get misaligned, others alignment stays perfect. Anyway the NBD rom just works, improves battery life, speed, I could go on all day.

Hi...
I read through the posts, noticing others were having similar issues, without anyone giving a clue of what is going on...
All of a sudden, this morning (while a colleague of mine tried the device) the touch screen stopped working. I couldn't do anyhting involving the touch screen...
I reset (soft) it, which didn't resolve the issue, and did a full hard reset, which got me the 'tap the screen to start configuring windows now' but didn't allow me to do anything else...
I cleaned, using a small soft piece of paper, the space between the screen and its cover.
Is there any way to check what is wrong? Any thing to try, to do, ... to see if the touchscreen can be brought to life again?
How can I open the device easily, to check if the connecting cables are still in place, and what cable should I look for?
Thanks for the help...
Dying to get Linux on this one :d:d
Found it, issue resolved!
Got a torx T6 screwdriver, removed the bottom lid. Removed the tape covering the lcd and touchscreen cable/plugs. I popped the connectors out, and put them back in firmly, and reset the bottom lid, screws, battery, battery cover and started up the machine, and the touchscreen was working again!
Thanks anyway...
Well, the touchscreen just doesn't respond both fingers or stylus.
Have no idea what could had caused the problem.
It seems that everything else is alright, w/hardware keyboard out image turns landscape...just doesn't respond to touches.
Should I return my phone?
Is it a warranty case?
Has anybody experienced anything similar?
Do you have a screen protector on your screen? If yes, try removing it (You can put it back afterwards). I have experienced this very problem. Another attempt is a Hardreset. If none of that helps, go for warranty.
Well, there wasn't a screen protector and I already tried hard reset - still, no response. I tried flashing a number of ROMs, they installed, but can't use 'em - since I can't finish "screen calibration"...
I guess it just shows that the problem is a hardware one.

Most definitely. It can be a problem with statics, maybe this can help you a little bit further. Also try touching in the corners of the screen (REALLY in the corners). Then go for warranty.
Well, thanks a lot!
Phone's being serviced, gonna take sometime for sure...
I've got this three times now - and it somehow worked again after a day or two. It happend always after I was cleaning the screen.
So my first thougt was, that a little bit of the window cleaner I used went into the device and short-circuit something. And when this drop of cleaning liquid dries, everything works normal. Makes sense, but that wasn't the problem.
At the third time, I discovered, that sometimes when I touched the non-reacting screen, the startmenu opens. Which made me recognize, that there must be something in the very upper left corner always "pressing" the screen. And so it was: With a brush (those which comes with an electric shaver) I was able to remove a noteworthy amount of dust/dirt. After that the screen instantly works fine.
Hey guys! I have a problem with my Blackstone....
After a while of using it my touchscreen does not respond anymore....
It just stopped working. The display works exept the touch....
any help wold be much appreciated...
touchscreen
I have the same problem. Touchscreen do not response anymoore, I tried to reflash the rom, but it did not help.
you probably have the digitalizer broken.
I got this changed once about 1 year ago (under warranty). It seems to be a big issue on our old devices.
If you are out of warranty, it's probably not worth to send it to the service.
You may try yourself following this thread
Sometimes if you paste a tape on the screen and try to separate the 2 layers of the digitalizer pulling the tape slowly, it may work for a while (temporary fix).

Hi guys, I had this problem one year ago. My warranty didnot covered such thing and it was too expensive to repair it, so I have read all forums and found the solution. The problem is indeed in the digitizer however it is not broken just the covering plastic screen seems to be pressed to it and generating a continuous touch so when you touch with the finger nothing happens. There are two solutions to detach the plastic screen from the digitizer - either put tiny plastic card below the screen from the edge or use a duct tape on the screen and pull quickly - this step may need to be repeated several times until the two layers detach.
I have done both processes and it works. With the duct tape it is safer but the problem appears again after some time, with the first approach I don't have the problem anymore.
Hope this will help you.
yeah, I know it's old thread, but could you please elaborate on this .. ?
covering plastic screen - do you mean, the layer that is in front of the digitizer, the one you actually touch ? that stuf is glued hard, I dont see how you could place tiny plastic anything from the edge, that means that you need to unglue it with hot air .. ?
I am having the same non responsive TS problem, but I dont think that it is broken also. only things that could go wrong are ZIF connectors, and the digitizer integrity, which is mostly not the case cause of the firm plastic surrounding it.
please respond, you could use a pic with an arrow to show me cause im in the middle of dissasembly process. tnx
Hi all. I replaced my battery, put the phone back together, and turned it on. Everything looked fine until I tried to use the touchscreen. It wouldn't register any touch. I figured I messed up the screen somehow when removing it, so I ordered a replacement screen - touch doesn't work with that either! Does anyone have a suggestion for what might be wrong?

Not to ask the stupid question...
Is the ribbon for the screen in the slot correctly? Seated all the way? Locked in place by that whatever the hell it is?
Thank you for your reply. Yes I have, it is screwed it and I've even tried pressing it down and touching it to see if it helps.

I have replaced the cracked screen on my PH-1 without issues... Since you are seeing the same problem with TWO different screens, I would check the connector on the board. Could be something like small piece of debris or dust or whatever. Remove the cable, and try inspecting it with a magnifying glass, if you can. Might be able to use a wooden toothpick to *carefully* clean it up, but I would only recommend that if you can actually see it well. You could also just blow a couple of shots of compressed air into it.
Other than that, I have no ideas, sorry...

might need a factory reset as this recilibrates the screen, back up ail your data first of course (pics, chats, game data etc). Not sure if recalibration apps still work, might be worth a shot first.
I had the same issue after replacing the screen. Someone on reddit mentioned the same problem and used a bit of foam behind the screen and its connection. I took a razor and trimmed a mm or two thick of some soft foam (used the foam that the screen was packaged in) and placed it over the connector. Touch was back after that, so it was an issue with the connection not being snug enough for me. Been over a month and everything is fine
