I had a keyboard problem with one of my treo and I tried to cut up the phone to pieces. I pulled all of string cables one for the keyboard and one for the display. Cleaned all and then assembled it. It looks like workink well but the touch screnn doesn't answered. I cut up again and plug in the display cable again. It works now again.
Since then I dont cut up the phone

You know I already disassembled it and assembled it back for few times, but it still not working. Everything looks very nice and clear - like new but...

New screen doesn't solve the problem. I purchased a new touch screen (lcd + digitaizer) - it start working for few minutes, then stop again. I put off the battery an leave it like this for a month. Than I switch it on - it works (I successfully unlock it, passed f..... alignment screen). Now I use it, but touch screen doesn't work!
Please if anybody now what is the real problem, let me now.

I have the same problem. I upgraded my Treo 750 to a new ROM. It worked for a couple of hours and then it doesn't work.
I have read in a different forum that you have to turn down the screen brightness to less than 1/2 and it should work. I tried that and it still craps out.
I am also looking for a new digitizer from ebay. Would this work? Or do I have to purchase the screen and digitizer.
Would a new screen or digitizer work or will it crap out in a hour or so?
Besides getting a new phone what would be the next step for a solution?

I think it is a software problem. With WM5, 6 and 6.1 the touch screen didn't work but on the newish 6.5 version here it works just fine, all the time!

same
am currently having the same problem whaat is d solution pls is it rom WM6.5? who hav solve this problem?

Touch screen is dead on my X1

Hello guys,
I got my new X1 few days ago, and today when i woke up i found out that the screen is not responding to touch...the stylus does nothing. I attempted a hard reset, but I can't align the screen because the stylus still does not work.
I managed to go to today screen and the mouse is working perfectly but touching the screen is not working at all, even through alignment.
No apparent cause to that.
Any idea how to fix this issue?
Thank you,

Try doing a reflash (with the generic ROM so that u won't lose the warranty)
If that doesn't work...i'm affraid there's nothing left to do but go and replace the touchscreen (it's still in warranty isn't it)
Sorry pal

Oww, sounds like a bad problem. You should indeed try a hard reset (though from what I see you've already tried).
If that's a no-go, it's warranty time. I guess you got unlucky. Good luck patching it up!

You can try installing X1 SoftTouch which will max out the responsiveness of your touchscreen in the registry without having to calibrate. I'm not highly optimistic it will work in your case but it won't hurt to try. The .cab is here:

Well guys,
you will never believe it, i read in a forum that some guy faced the same problem with another WM device and he moved the battery and left it overnight and the second day the phone was alive again.
Guess what? I did the same and amazingly it worked.
By the way thank you (ring-bearer) for the cab file, i installed it and it has improved the touch responsiveness.

Touchscreen Fixed
Hi Thanks for that. I tried the take the battery out and leave it over night trivk and it worked for me to! Brilliant! Upgraded the touchscreen with the cab file to - all good. Thanks again.

for me this trick (remove the battery for one day) doesn't work.
also i changed the touchscreen but no results.
maybe the problem is somewhere else

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.

X1i Touch Screen Stopped working??

Hey guys,
I've had my X1i for a year now. No hard falls most falls are on soft surfaces. & Suddenly today morning woke up & the touch screen isn't responding. So I looked up posts, some said turn it off & turn it back along with removing the battery & it should work fine. Tried that, worked for a bit then stopped working again. Also tried soft-reseting & gave the same result. So is there any other method you guys know ? I'm thinking the other type of reseting..forgot what it's called but that'll delete everything so i gotta back things up first. So any solutions? & thanks in advance.

Have you got a screen protector on it? If so, try lifting the edges of it a little.

Nope, no screen protector. Does it have to do with any .cabs i've installed before ? Or they're not related? Is the battery related? Could it cause something like that?

I once run into the following, it may help you too:
after installing an app(from a cab) my screen was allmost non responsive.
Calibration didn't help.
I have "Advannced config" installed, uppon checkin the sensitivity it was waaaaay down, even under default.
Hope it helps for you too =)

i had the same problem to on my proto x1
it completely stopped working and i tried everything (reflash rom, boot android)
but all without luck so i bought a replacement screen
after a while my touch screen started working again but still occasionally fails
i have not yet replaced my touchscreen, i am thinking about a loose connector or something...
btw i was on official r3 fw

Where is that located? Where can I get a new one?

here is one thread about it, there should be others if you search some more than I did
and this would be a means to get a new one (official site, similar price), if it really is the cause and you don't like to tinker
cheers and gl

If your LCD is working, then it could be bad digitizer like mine instead of the ribbon cable. (Well, I use X1 a lot in humid place like bathroom.....). Just pay a few extra to buy the LCD+Digitizer for about ~$30 that will save you a lot headache for just the digitizer alone. There's a thread in X1 accessories forum.

touch screen does not work at all

Hello. Yesterday morning when i woke up suddenly my touch screen did not respond any more. I try reinstalling windows or hard reset but now i can not even get over tap the screen.Please help me. You already helped me once when i was going to throw it away because i thought it's a hardware problem and it was a software one.

What you need to do is fully charge the phone, run a backup usin PPM or sprite then do a soft reset and leave it for a day, if that doesnt workt hen run a hard reset and it will fix it, been through that problem too a couple times and it ends up workin fine

Thank you
Thanks a lot. but please tell me when you say to leave it for a day i should leave it with baterry in or out. Or do you mean to do the soft reset and leave it for a day to the screen where it sais to tap the screen. And by a day you mean 24h?Thanks again anyway

Ok.But where can i find a new lcd? And how much is it one?

I did the soft reset and leave it for a day then it worked but when i wanted to charge, it happened again and i have the same problem now.Any way a thing it's certain it is a software problem.If you have other advice please help.

Hello I had the same problem.
I installed several versions of Android and nbh files.
The problem occurred with versions nbh for Froy version of Android.
As I had saved the versions that were tested. I tried to install previous versions where I knew the touchscreen worked correctly. In my tests with this file to the touch screen work again: kaisimg-panel2-320-24-05-10.nbh
I hope that helped

I had prob woth touch screen and non functional front camera. Restored function by replacing flex cable. This flex cable has the buttons for the keypad as well as supporting the front camera. When I examined the flex cable, the portion that moves in and out when sliding the keyboard appears to be slightly damaged on right and left sides. The damaged portion does contain very thin circuits.

Not sure why this was posted in Accessories but I'll move it to General for you.
