Touchscreen just stopped working??

I was tapping away happily on my little used XDA2i and suddenly the touchscreen stopped working. There is no damage to it and I tried to soft and hard reset and nothing works.
Now I am at the opening screen after hard reset and it looks like the touchscreen is kippered.
Any ideas of a cheap mending solution?
Just to clarify - the display works fine it just doesnt respond to touch.

dude...i think the connectors must have gotten out of place from the motherboard...a simple solution is to go and hand it over 2 da nearest phone repair shop and i doubt it would be cheap so just find a way to open the pda(which is very very very simple and easy) and i have done that a hundred times and the xda2i still works perfectly..one of da reason why i love it soooo much,lol...anyways...the connectors are visible ones you get to open the back panel and see for yourself...

I have just got an XDA 2i. i got it very cheap in a not working state and the problem was as you described. The machine would power up but not accept input from the touch screen. I disassembled it, cleaned it up and rebuilt it and it now works fine. I assumed it was the connector for the touch screen. The job was quite simple but i am fairly technically competent. A replacement screen can be found on Ebay for as little as £14 GBP.

Ok, I have had this to pieces and also dismantled the screen to see what the problem might be, gave everything a wiggle and then rebuilt the machine.
Touchscreen still not working though the LCD still seems fine and so i am assuming that I haven't broken it.
Not sure what to do next as I cant find any XDA 2i touchscreens on fleabay. Anyone had exactly this problem and replaced only the touchscreen (not the LCD too) and could give me some tips. I couldnt see how to replace just the touchscreen ie where it would connect to the mainboard. Also - Stev - when you said you cleaned it - do you mean you actually cleaned the touchscreen part or the machine generally.
Thanks

Touch screen problem with no alignment
Have got 2 Qtek 2020i with defective touchscreens.After hard reset they get to the "align screen" image, and the PDA responds to the touch by moving the cursor between the 5 adjustment points - but alignment seemingly never occurs, as I can continue forever.I guess the touch screen in itself got misaligned - anyone with experience in this ? .I found replacement touch screens from Hong Kong for as little as $6.99/pc, and $2,50 for shipment to Denmark.

I have bought a replacement touchscreen from ebay, however it looks like it needs soldering at the back and the ribbon on the screen is a different layout. Anyone have any idea what to connect and to where?

Does anyone know whether the touch panel from XDA II will be able to fix to XDA IIi ? I am having problem with my XDA IIi(Alpine) it seems the touchscreen is not responsive. I have already tried opening the Alpine check the connectors it seems to be okay so i am suspecting the touch screen is the fault. I have found this website http://mobile.brando.com.hk/TouchScreenO2xdaII.php selling the replacement touchscreen but it stated there XDA II. Will it be a match for Xda IIi? Will it be easy to fix? Anyone with experience please help. Thanks.

I bought one on ebay for £12.98 that said XDA 2i and it looks like the one in your picture, which I dont think is the right one - I reckon that is the XDA 2 one version. I phoned the company I bought it from, in London and they said if I send the whole lot to them they will fit the new screen for £20 more which seems fair enough. That would mean the touchscreen fitted for £32 - a lot less than the £80-100 I've seen elsewhere.

After searching for answers... Screen taps not responding

Hi there. I picked up an important call whilst in the shower. Very little water fell on my Kaiser but I belive that this caused the screen to stop working. Or I have dropped it as well.
Now I tried the business card remove dust particle trick. Didn't work. So I disabled cube / Touchflo. Then I reinstalled my ROM. Basically, I can't align the screen... I tried using the Remote Screen Alignment tool as well.
What's weird is that when you leave the phone for a couple of seconds, the battery conservation feature kicks, and when I touch the screen, the screen powers back up. So I know the screen works but just not properly.
Do I have to replace my screen (or just the TOUCH component of it)? I'm not too good with hardware but can I take it apart and fix the problems?
EDIT: For those facing similar problems, use the trial version of SOTI Pocket Controller to work on your Kaiser remotely.

I'm sure someone knows what to do... please help.

I had the exact same issues you were having, I had to send it in finally so I hope it is warrantied.

nope, its out of warranty. I'm thinking of using pocketpctechs or some other similar service. Any suggestions?

I would just order a new screen and replace it yourself.

Did they replace the entire screen or jus the TOUCH component? I heard that the TOUCH surface is way cheaper.
Also, I'm not too sure how to replace it myself.

when my tilt was in warranty they just gave a new device but on the call they said the screen was dead even though it displayed and had minimal responce.
I could be wrong but I don't think it would be easy (if even possible) to replace just the touch surface of the screen.

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.

[Q] Help me solve keyboard mystery please!

So here is my story.. i have a perfectly working kaiser, and one with a broken lcd.. but both of them are in terrible cosmetic condition.. so i decide to order from ebay a full housing (with keyboard included) to make it look good and give it to my brother as a present..
I perfectly disassemble the device with the working screen and easily install it in the new housing.. but when i turn it on i realise that the only working hardware keyboard buttons were q e u o f h l and some arrows i think...
My first conclusion was that the keyboard included in the housing was not working correctly so i decide to use my old one. but to my surprise the old keyboard also has only the same working buttons!!!
after that i also tried the keyboard from my other kaiser ( with the broken screen) with the same results.
So up to this point, i guess it is safe to assume that the keyboards have no problem.. but then the mystery grows cause i exchanged every single piece of the phone with the broken kaiser's parts and the problem remains the same...
Any idea?? i am an engineer and problems like that that i cannot think of a reason that they are happening drive me nuts!!! please help me sleep at nights..
thanx in advance!

Hooray! Someone else who has the exact same problem as me! The phone I have had the LCD screen replaced and once it was reassembled, the keyboard is wacky. I tried reseating it and the same keys you mention are the only ones working: Q E U O F H L, CAP/Shift, Tab, Space, Enter and the 4 arrow keys. Nothing else works. I'd love to see if anyone has a solution to our problem. =)
Also, I'm not sure if it does it for you but the backlighting doesn't turn back on once it goes off - even when pressing the working keys. I found other posts on this forum with similar problems (with no replies) but their keyboards were not working at all. There has to be a simple solution that we're missing if it's this common.

Thats really weird that we have the same keys working... it really has to be something we are missing... but i have changed everything..
the only thing i didnt change is the lcd, so now that you are telling me that this happened only after you changed the lcd, it got me thinking that maybe the lcd is not as inocent as it may seem... cause,ok, my first thought was like wtf the lcd couldnt mess up with the keyboard.. but now that i think about it it is the only thing i havent tried to replace.. i have a broken one but still quite operative, so i will try with this one and get back at you.. if in the meanwhile anyone else knows something or has an idea, please help a little bit!

Like you, I cannot find any reason between the keyboard and the screen that would cause this. They're not connected in any way or share any cables. They connect to different parts of the main board... there's no logic that I can find.
I got mine second-hand and the original owner said she had the LCD replaced because of a couple dead pixels. The keyboard was working fine before that. Let me know what you find out. I was planning on ordering a replacement keyboard assembly from eBay but since you've tried a couple, that saves me from wasting that money.

Unfortunatelly the extra LCD i had was not operating at all, so the test i wanted to do failed, and i still dont know whats causing the problem... i am more or less convinced that i have to buy a new lcd but it is a bit of a risk to change the screen because some buttons on the keyboard dont work, dont you think?? anyway i am wondering y nobody else has nothing to say... this hasnt happened to anyone else??

thank you for your reply! but i don't understand how this would help for our problems..
i talked with htc yesterday and they told me it couldnt be the lcd, but during the lcd replacement probably the flexiboard was a little torned (needs a microscope to be verified..) i am giving it for a free test on monday so i guess i l have a more detailed answer soon!!

Hmm, that's an interesting find. It's odd that the same problem exists on different phones, unless it's a common section/piece of the board/assembly that gets damaged. Are you going to try and use the assembly from your other phone? Let me know what happens. I'd like to know what piece I need to buy to get mine working again. =)
