Touchscreen Not Responding / Malfunction

I've been using my HTC Diamond for about 2 weeks now.
Bought it from www.plemix.com and it came unlocked , and I had no trouble at all using it and installing the HardSPL's / updating ROM (Dutty's Diamond v1.6) .
Today I ran the TomTom Navigator 7, and after a while it started to make continuous sound - the default sound when a button is pressed or touchscreen is tapped- , so I did soft reset a few times, didn't solve it, touchscreen was kinda jammed, and I took out the battery. A minute after I put it back, and it worked fine, I took some photos right after, and everything was working fine.
Then two hours later, I took out my phone from pocket to check the time, I see it's halted on the photo screen, and no response at all. So I just turned the phone off by taking out the battery, and just left it off until I came home.
Now the touchscreen is not responding to any taps or clicks, except that it seems that it still detects any sort of tap/click, because the backlight comes on from dim state when I try to tap it.
So it definitely means the touchscreen is not completely dead, but it's just not functional most part.
Hardware buttons works fine, but I'm stuck at the initial "Tap your screen to begin configuring your Windows Mobile" after hard reset. I even updated the ROM to Dutty's Diamond v1.8 just now.
Since I can't do anything and just leave it idle, it goes to [ Align Screen ] page, and still I can't press any cross, since the touchscreen is completely not responding.
Anyone had this screen death problem? Any method of solving it?
---Updated---
Just now the touchscreen worked for 30 seconds, i could actually align the screen, then it showed me the Date/Time setting page, where I could scroll the cities , but then it stopped working again. So i'm still at Date/Screen page...
--Updated--
The touchscreen works for 2 minutes after I do a soft reset / power on&off, or I should say, it works until you press some hardware key on the bottom (volume up/down buttons doesnt affect this).
After I press any of those buttons at the bottom, the touchscreen stops working.
Also, after I turn on the device, enters WM, and runs TouchFLO3D, for the entire time touchscreen works, it's constantly pressing the tasklist dropdown (upper right corner of the screen), making it constantly pop down the task list.

have you tried a hard reset?

Yes, like 3 times. Wiped everything, OS, ROM, NANDFlash.
Also updated the ROM from 1.6 to Dutty's 1.8 ROM. Everythingn works fine except for the Touchscreen.
Right now, when I turn on, the touch screen seems to be pressing all the time at the task manager part of the screen (where the [X] is), its popping up all the time the task list, then after a while, like say, 2 minutes, touchscreen again ceases to work.

Not really promising, but you could try to remove the screen-protector. Perhaps this releases any tension onto the screen.

Thanks. I've thought of that, maybe I'll try later on.
For now i'm suspecting that maybe water went in through, so I've put the phone upside down to maybe take out the water using gravity for 2 days.
It seems like it's working better now, with longer hours of normal functioning..
I'll wait and see one more night... if water is the cause of the problem, it should dry up in say 3-4 days.

It may sound strange, but pit it face down on the carpet and rub it around for a while. Its how I fixed mine. Don't ask me why it works but I had the same thing happen. I think somehow the electrical charge got dissipated from the screen and the static from the carpet recharged it.

Actually your words makes a lot of sense
My Diamond was acting completely alright today, used GPS for 2 hours and called a few people along with many weather updates.
Seems to be working fine now...
But I think what you said is pretty reasonable, since when I rubbed my dead screen , after a few rubs it started to work (2 days ago).
Thanks

yeah this had happened to me about a week ago exactly the same thing I had hardspl mine and updated radio to .05 and then a few days after I had the identical problem. However I took a shortcut and sent the phone back in and requested a replacement claiming it was defective they agreeded and sent a new one however this one already has .05 radio on it so I didn't have to hardspl it. I can't say any of these things would have worked form me as I did not try them byt symptoms are identical. my .02

Tilt Problems...Help

I have an AT&T Tilt...until Friday it worked great...It has WM6.1, HTC Home and spb Mobile Shell.... Friday I changed the screen protector from the same pack that I have used for months and then the problems started.... Randomly when I try to touch the screen it appears to lock up, but then the start menu will drop down. The soft buttons work, but then every once in a while the start menu will drop down again. I have soft reset to no avail, but then in an hour or so it will start working fine again. Anyone have any ideas, does it sound like a hardware or software problem? should I hard reset the phone and start over? Help
Thanks
Andy

pull off your screen protector.
chances are you have it touching on a side which causes pressure somewhere else and it (touchscreen) thinks its being touched in a different place.
which in turn makes you believe its locked up, since it does not have multi-touch touchscreen it will not respond because it is perceiving a touch somewhere else.

Thank You...Thank You... I believe that was the problem.....

Screen lighting issue.

XDA-Dev:
I hope this finds you in high spirits and good health. Just a day ago my phone started acting peculiar regarding the lighting of the touchscreen.
Firmware: 1.6 // Build: DRC83 // Rooted: No
Damage: Slightly scratched hard plastic from dropping 2-3 times. Otherwise, outwardly pristine
Upon purchasing the phone, I immediately noticed that the screen would creak if it was pressed on the bottom right hand side (by the send button). The right side of the screen also protrudes slightly higher than the left when in the open position. I have owned the device for about 7-8 months now and have noticed that on the rear, when in open position, there is a scratch where the sliding mechanism moves. The paint is stripped and the underlying metal is displayed in those areas. And now on to the issue at hand:
When the phone is closed (touchscreen only):
- When pressing MENU, or any key that would normally illuminate the screen, this does not happen. The screen stays dim, yet the lights on the buttons bellow it brighten.
- If I slide out the keyboard while the screen is supposed to be on (meaning the buttons are lit up), nothing happens.
When the phone is open (keyboard presented):
- And the screen is off, if I press MENU, the screen comes right up with no brightness issues.
- At this point, if I close the keyboard, the backlight disables itself. The screen is NOT completely blank. If I reflect the light of the room off of it, I can just barely make out that it is indeed displaying whatever task it was that was open, but if I were in a dark room, there would be no chance of recognising what is being presented.
- Continuing from above, once the screen's backlight is disabled and I reopen the keyboard, it does not turn back on. I must turn off the screen and turn it back on for the backlight to resume normal functioning.
One would think that if the issue lies in a loose wire that once the keyboard is extended that the backlight would regain normal functioning. Because this is not happening and that it is only working under certain circumstances, I cannot accurately ascertain whether this is a software or hardware problem.
Attempted remedies:
- Soft reset (both rebooting the phone by powering off and on and by going into the reset menu)
- Hard reset (by going into the reset menu and hitting ALT+W, etc)
Neither of these attempts succeeded in restoring functionality of the backlight. I've also search high and low through the settings, but see nothing other than 'Brightness' under 'Sound & Display.'
It may be noteworthy that I have the paid application 'Power Manager' installed. Though, perhaps not since this issue was still occurring AFTER the factory reset when no foreign applications were installed.
If you require any additional details, feel free to give a reply with any questions. I'm sincerely hoping I don't have to deal with T-Mobile or HTC to have this repaired. Any tips, ideas or possible solutions would be greatly appreciated!
Regards,
Ian

Update on issue:
On the way home from work, as the battery was on it's last leg (less than 10%), I turned off the screen while the device was in the open position after finishing a text. Upon attempting to re-activate the screen, it would not do so. As always, the side buttons lit up, but the screen was blank no matter what I did. I could hear the vibration from receiving texts and the red 'omg I\'m dying LED' was still flashing, so the device had not died.
Returning home, I gave it a reboot by removing and replacing the battery. I've kept it in the open position since it has been plugged in and am quite afraid of manipulating the slide mechanism any further.
I'll be calling t-mobile to get their opinion on any further troubleshooting momentarily and report back.

Sorry for opening an older thread. do you remember what t-mobile said was the problem? i am having the same issue.

The ribbon wire in the slide mechanism is either broken or pulled out of socket.

[Q] It Anyone Else Having Touch Button Problems?

Is anyone else experiencing the occasional mixup when hitting the back button? As not always, but many times regardless of the application thats open, I'll hit the back button and the search will come up and I wondering whether thats a common problem or a sensor in my phone is defective and I need to exchange it for a new one...
Thanks in advance

im having a different problem with the buttons. a lot of times my first touch wont register and i have to press it multiple times for it to be recognized.

I've noticed that my touch buttons aren't as sensitive as the touchscreen, and that I need to use a lot of pressure to get them to activate on the first try.

not alone there.. same issue here. I have a clear screen protector over them though.. though it shouldn't be a problem.. I've had the issue even before the protector so..

I have a problem with the back button too, not the other ones. However, when I press a spot a little to the left of the back button and not exactly over the button, it seems to register the press correctly.

I have found that the buttons just do not like any other finger than the index finger try to use the thumb and it will go to search or do nothing.I also returned my first phone as the buttons were terrible 80 percent of the time they would not work.So there maybe be a flaw in some of the phones as this one works fine even with the phantom skins on.The first phone would not even register a response with the skin on.

The buttons on the Captivate suck.
Buttons, as a construct, are well known.
The functional priority of the button is not a mystery and hasn't been for 100 years.
It has to click or otherwise give the user an indication the button has been pressed far enough to take effect.
It has to be tacticle. You have to have some way of knowing that your finger is on the button before you press it.
You have to have some leverage to put enough force on the button to make it move.
It has to be about the size of a finger tip.
It has to be visible. If you can't see it you can't press it.
It has to be different than other buttons that are millimeters from it.
It has to react the first time you press it, or you will naturally press it again, achieving unwanted results.
In all of the above, the Captivate fails.
The T-Mobile Galaxy has more a lot more real estate below the buttons to allow your fingers to get on to them, and a raised ridge on the rear surface of the phone exactly to give your other fingers something to grip against to increase aim and pressure.
But the Captivate has a nice lot of space at the top OH YEAH!

The only problem I have with the buttons is that I can't see them in a dark room

I'm getting something similar. Sometimes when I hit the home button the search button blinks as if I had pressed it, then brings up the search screen. On my first captivate (mfg. date 7/16) sometimes it would happen once out of every hundred presses and sometimes it would happen 3 out of 5, very inconsistent. I traded that one in for one with a later manufacturing date (8/10), and my new one does it too but maybe only 1 out of every 100-200 presses. The fact that the search button blinks makes me think it's some kind of short/hardware issue. The back button has only triggered a search for me once, and that was on my first phone.

So this is a hardware issue or a software issue?
My back button on my phone must be pressed 4-5 times sometimes before it will register. The phone did not have the issue when I got it, and a friend of mine who has the Captivate as well does not have this issue.
It may be my imagination, but the phone seems to register touches better after I run a task killer or after restarting the phone, but tends to have issues when multiple apps are up and running.

I was having a button problem as well but fixed it by upgrading to JH3. h t t p://forum.xda-developers.com/showthread.php?t=767666
Your mileage may vary but it worked for me.

May be my imagination, but it seemed to be more isolated to back button on JH3 than JF6 on my machine. My perception is that if I take an additional half-second pause before pushing back button it registers more often. Do not believe it is hardware though. I believe that your home page(button), settings (button), and search(button) all reference something that resides in permanent memory(ROM) whereas the back(button) is trying to recall something that is in temporary memory (RAM) and possibly similar to lag issues may be related to Samsungs somewhat proprietary file allocation system. I am by no means computer literate enough to ponder concept any deeper than just mentioned.

I was having a problem with pushing the home button and the search would come up. I took it to a AT&T store and because I was still in the first 30 days they swapped it out for me.

i'm having a completely different issue with my touch buttons. my back button will register multiple button presses even when i'm nowhere near it. it's quite frustrating to be in the middle of an app and all of a sudden the back button goes off 3 or 4 times and gets you back to the home screen. i've tried searching the forums for some resolution or to see if someone else has had this, but not yet.
Edit: I must not have searched thoroughly enough, found another thread on this issue. http://forum.xda-developers.com/showthread.php?t=858873&highlight=back+button+issue&page=2

[FIXED]: Phone Laying Flat, HOME/BACK are Non-Responsive

So you've played with changing button sensitivity, heard about perhaps removing the screen protector, but still don't get it?
I think I might.
Try this, let me know if you guys can confirm, then perhaps we need to send info to HTC?
Unlock your screen
Place your phone on a level surface so its curved back can rock back and forth.
Enter the app drawer, so pressing HOME will actually do something.
As gently as you can, steady the phone with one hand, and touch HOME (It should work)
Now, re-enter the app drawer and press quickly on your phone's HOME key. This will cause it to quickly rock back and forth a bit and shake.
Press the home key all you want, it shouldn't work... especially the more you bang on it.
Wait 10 seconds.
Steady your phone again, press HOME gently. It should work.
The theory? Something is programmed in the phone that if it detects rapid shaking, like maybe in a pocket or being handed back and forth during watching a video... to turn off the buttons to prevent undesired actions. BUT, the curved back of the phone naturally lets this motion occur so it's triggering when it shouldn't.
If you're particularly twitchy, maybe that can cause it from time to time while even in hand too?
SOLUTION:
Run calibration tool a few times until the symptom goes away. Try alternating between pressing more firmly or more softly to make a difference. Take care to center your fingers on the letters.
If you experience bad button behavior while phone is on a flat surface, re-calibrate:
SETTINGS->Language and Keyboard->HTC Sense Input->Advanced->Run Calibration Tool

I couldn't replicate this problem. The home button works as intended while being rocked. I also haven't found to have any button response issues that some encountered.

Heh, come on man... the phone has BOOM Sound, it was meant to be rocked, no?! :laugh:
Serious note though... yeah always have thought the buttons worked fine too and thought other people were crazy...
I lay it flat though casually press them, they go away and don't come back.

Also couldn't replicate it. Basically the home/back buttons work when they want to, which apparenlty is about 95% of the time. The other 5% is just purified annoyingness.
Allegedly HTC has fixed the button problem in 1.29.XXX.12 which so far has only rolled out to unbranded phones in Europe and Asia. However if you have the international phone you can install the newest Android Revolution ROM which is based on the .12 software. Everyone who has .12 seems to agree that the button sensitivity issue is gone.

Re-ran calibration tool pressing normally and it seems to have fixed it.
No amount of shaking or rapid pressing causes the phone to miss a button press.
This is with US Version of phone w/ screen protector.
