you should try to hard reset or flash with other rom.. if it doesn't work i think you should sell it.. coz if the one broken is the lcd, it will cost quite expensive..

I had the same problem. Some parts of screen did not work. I had to send it to the repair service. And they have replaced a new screen.
Probably you need to do the same.

thanks
don't another way ?

Maybe dust inside your LCD... Like my, the tech guy says too much dust in my LCD...

First of all, the LCD has nothing to do with the touch screen.
It is a separate thin layer on to of the LCD called the digitizer.
It should not be as expansive to replace, but before you send it to the lab, try the following:
1) If you have a screen protector of any kind remove it.
2) See if you can get to Start->Settings->System->Screen->Calibrate
(maybe using hardware keys or some kind of remote control app)
Try to recalibrate the screen.
3) Try to hard reset your device (make sure you backup all data first!) by holding camera and comm manager buttons (on the left side) and pressing reset.
If non of that works you definitely have a hardware problem (possibly a loose connection) and should send the device to a repair shop.
Changing ROM is unlikely to solve this problem and will only void the warranty if you still have any.

a very big problem with "...tap the screen..."

after months of using my device, qtek s100, after a reinstall of windows (same that i'm installing everytime) when it tells me "tap the screen..." i tap, and ask me for calibrating. I'm calibrating him, and still ask for calibrating, with no end...the problem was manifested when the windows still worked and everywhere i was pressing, it was like i was pressing on Start everytime, even if i was pressing on clock for example. what should I do? pleaseeee
hello mate, why not try to upgrade your OS
hy. i've upgrade it to 1.13 which everytime worked. then i've upgrade it to 2.03 which has the same problem. does exists another OS to upgrade?
Ady_uaic, I also have that problem and FINALY i've figured it out...
above the LCD screen, there's a thin transparent glass screen (touchscreen), which has a small ribon that connects to your phone.
check this link for a picture of it: http://cgi.ebay.com/OEM-Dopod-818-i...ryZ41343QQssPageNameZWDVWQQrdZ1QQcmdZViewItem (*)
The thing is...once, when i was opening my phone, i did a small cut on the ribon by mistake and now the screen behaves like that...I've found that if i gently push that touchscreen to the right, the ribon will sometimes bend a little bit and will make a perfect contact which allows me to keep the phone aligned...unfortunately this is only temporarely since sometimes the ribon moves and of course, the alignment is lost...So, i would advice you to check if the ribon is intact and not broken somewhere...if it is broken, then you know what to do: Buy a new touchscreen and/or an LCD w/ touchscreen included.
Hope this helps...
Regards,
Keeper
(*) although similar, do note that this touchscreen AIN'T for the magician, so don't order this one!
hello..thank you for your quick answer..i will try and i'll let you know
Sound like a hardware problem ... try flushing a new rom, if not , take it to a lab.
open up the device and reconnect the display ribbon wire properly after cleaning with a soft cloth.
the ribbon may disalign after a fall or dismantling the device and certain other factors.this is the only possible fault.if it doesn't workout, you may have to get the lcd changed.

Touch screen problem ?

Hello, I bought a second hand prophet. But I have a problem with the screen : the screen does not respond exactly where I put the pen. For exemple, on the keyboard, if I put the pen on the "E" key, it is the "D" wich is pressed ...
This only happen in the middle of the screen. No problems on the top or the bottom of it.
Of course I tried to re-calibrate the screen many times but it does not solve the problem.
Does anyone know where does this problem come from ?
Thanks a lot !
hello
do the screen alignement , it helped for me
grtzzz
you can find this in settings___system ___ screen and choose align
Like I said, I already did the re-alignement. But it didn't solve my problem.

Well it is very likely that your touchscreen is damaged but not your LCD. There is actually 2 portions to the screen which most ppl assume there was only one(well I did initially until finding out later when my screen broke and got it replaced). Anyway, if you've tried re-calibrating it and doesn't work..maybe your screen protector (if you do use one) maybe be at fault? Other than that, worse case scenario, it is your touchscreen that is physically damaged. FYI it is not really expensive to replace compared to the LCD part.
Speak to njbridges if you need to get it replaced.

I already upgraded the ROM to latest french version ... It didn't help in that.
Anyway, thanks a lot for your answers !
I had the same problem. Unfortunately it was a problem with the touch screen which was fixed under warranty.
the simply answer is
try to change ur screen protector, or just remove and re-put it on again
just try...

Hello.
I tried to do that, because I had problems to align screen.
I changed the touchscreen with another from a broken LCD. But now all I can get is a white screen, then a sound (like the starting sound when you make a hard reset or remove batery) and after black screen again.
What can I do to bring it back.
I've noticed that the touchscreen had some white glue where is the connection with the LCD. Do I need to replace that glue, maybe is a special glue with small voltage conductibility ? Or ? Help!
Anyone changed the touchscreen ?
PS: I think I will start a new post, maybe I will get some answers!

When you buy a new touch screen you buy with some conectors or only the plastic rectangle ?

When you say cut it means that a part of the conectors still remain on the touchscreen (under the touchscreen). Or no conectors at all on the touchscreen and that means you removed the connectors (pulled out).
Do you know if I have any chance to take another touchscreen from a defect device and work ?

Digitizer replacement?

The warranty for my HD is gone and I would probably need to change the touch screen digitizer myself, found these on ebay for ~60€, but does anyone know how to change them? Again, any help would be appreciated!
Originally:
HTC Touch HD, it has been a wonderful phone until now. I have encountered a wierd problem with the touchscreen.
First the touchscreen stopped working completely, after awhile it suddenly started working, at first it recognized some bits and pieces but now it recognizes every touch as normal, except..
It is very inaccurate and the "sum of inaccurity" seems to change depending on where I push the screen, the screen alignment option in settings does not fix this.
I recorded two videos to show this problem better:

Any help would be appreciated on how to fix this!

I have handled it with great care so no big knocks or drops. Ill contact the store about the warranty. Just wondered if theres a way how to simply fix this.
Just noticed, the screen works normally sometimes for one touch, then it goes back to the inaccurate **** :/
Im now guessing that some cable could be loose or something like that?
Have u tried recalibrating the screen? I can't remember exactly where I found it, but its in programs or settings somewhere.

Yes I have..
Anyway I RMA'd it now. Hope I get a new one
I can tell you from previous experience, HTC does NOT warranty touch screens. You mentioned "a store", so I hope they help you, because HTC will not. >sigh<
Seems a little unfair if they don't seeing as the HD is purely touch screen!

Hmmh, well the store probably sends it to some service center here in Finland that fixes HTC phones.
Indeed sounds very stupid if the warranty doesnt cover the touchscreen.
Perhaps my HD suffered from something else than a broken touchscreen, eg. mainboard or a chip that controls the touch screen. Who knows I'm just hoping it "passes" the warranty :|
Well... Had Hard-SPL on my touch hd and duttys 1.7 rom, so the warranty is gone
Didn't know they were so picky about it, they said it would cost 605€ to repair the screen. So now I should probably start looking for a screen digitizer on ebay and some help on how to change it... Already downloaded the service manual, but there was nothing on how to change the digitizer, could anyone here show me some light to this? Thanks.
I have dismantle my HD to see if there's any way to change only the screen (it's broken)
There's no way, as far as I saw. You have to replace LCD, tourch screen and screen. It's one piece and there's no way easy way to open it without break it.
You can find all of them for about 200E.

Another sad story // hopefully with a good ending
I kinda have the same problem as Viba and others. Sorry for the looong post. But decided to describe in more details my experience up to now, and hope you can help as well.
All of a sudden, I started having problems with the touch screen of the Touch HD. I started noticing that whenever I touched the Touchflo buttons, the phone vibrated. Soon I came to realize the if I touched in some spot, the phone recognized that I was touching lower, to the point that it could not recognize touches in the taskbar, for instance.
The united has 2 or 3 months max. It had some falls before and I do not really know who (or which one) was the culprit.
Tried this as fix: re-alignment, hardresets, Official ROM upgrade. Then I started reading and understanding that the problem was probably the digitizer ("nice to meet you").
I live in Brazil and the Touch HD is not expected be released here any time soon. So the few HTC service centers do not know how to fix it and do not have parts for it. And also, I bought mine from an auction site by some user who bought it abroad, with no warranty whatsoever. I am left alone in this.
I was very frustrated and eager to get my device running again. So I started looking for a new digitizer and also the tools to open my phone. The digitizer (just the digitizer, not the LCD screen) I ordered from an ebay shop in Hong Kong on Monday and is expected to still arrive sometime in this century (IF Brazilian port authorities do not mess up). The tools arrived yesterday.
I downloaded the service manual and said to myself, let's see if the digitizer problem is maybe due to a loose flat cable. Got to work and carefully disassembled the device as per the service manual. (I have to say that, although I try to be carefull, I always scratch, bend or mess something up when I do jobs like these. So I was afraid of cracking some plastic or worse and actually did some.)
Up to where the service manual show, it went incredibly very well. But that's the problem. The service manual guides you to disassemble the unit up to the point where you are with the bezel, LCD and digitizer in one piece.
But hey! I saw zillions of internet shops selling the bezel (actually, the hole housing, but with no LCD), the digitizer or other parts separately! What is going on?
So I started trying to unmount the bezel, LCD and digitizer. Tried several things. It got really late. I was impactient. So I tried splitting the digitizer from the LCD, by inserting a hard plastic aluminium tip between the digitizer and the housing. A very thin plastic kind of tape came out (at lest part of it). So I tried doing it more. No success. And then I put a very thin screwdriver between then (just enough to get an ulgy bent it the plastic housing).
When I had played enough with that puzzle, I gave up and began mounting everything back. The good part is that I was able to get everything back and the phone is working. Well, except for the digitizer.
First thing I did was to kidnap the wife's Nokia E71 I bought her last month and she is not using yet (she couldn't learn to use yet; well, she hasn't even tried it), because I have to have mobile access to my emails.
And I really started now to consider other alternatives. Will some user like me EVER be able to change just the digitizer? Is it even possible? If it is, I would like to give it at least another shot.
But I am also afraid that it could be another part which is in failure. I just don't want to spend more $$$$ in this. It would be better to buy another phone (and maybe not a complete touchscreen - gosh, I miss my Tytn II). I so regret being a gadget freak and not waiting a release in my country.
Shoud I send my phone abroad for a service center repair? My sister lives in Dubai and she may be able to help.
Should I give up my unit and seel the used parts in ebay?
Hope to hear your suggestions. Thanks anyway.

before doing this what about removing hspl and reflashing back a stock rom
change shop and you might, and i say MIGHT, be lucky
much better than screwing up the machine

Sucks that the digitizer couldn't be removed separately, would help alot if someone knew how to do this, if even possible..

I have already tried with 3 custom roms and 2 original SPL:s with two original roms.
The Finnish law allows me to get my HD replaced if I could prove that the custom rom didn't brake the digitizer. Already sent some emails to the local repairstation for HTC phones here in Finland, lets see...
I run a repair center (US). I have not gotten curious enough to take mine apart, but if someone has a dead one to experiment with, PM me.
Broken digitizer glass
I have the same problem with the digitizer glass being broken. I have had the back off the phone and stripped it back as far as I dare, but the service manual just doesn't tell you how to replace the digitizer and glass only. Checked out youtube where there are many videos with instructions on how to replace the screens and digitizers on lots of different phones as well as the iphone, just nothing on the Blackstone yet.
Any one else found a solution or decent instructions?
Today I disassembled my HD too, found a loose screen wire but nothing else. Even when I attached it properly the screen didn't work.
Has anyone found out how to change the digitizer?
some info
Hello,
I am also have HTC Touch HD, and I am also thinking about replacement of touch screen and housing because of scratches. Here instruction in Russian
http://www.pdacenter.ru/razborka/htc-touch-hd/
step 24 is not shown on the picture, but there is mentioned that in order to replace screen you should push it forward from back side of the screen; also mentioned that screen is fixed with double sided tape (probably it is fixed to the touch screen)
Also, did you try to use any polish to remove minor scratches on the touch screen? HTC Touch HS has resistive screen and probably may be polished (in contrast to capacitive touch screen that has some coating).
All the best
Also, about this problem see
http://forum.xda-developers.com/showthread.php?p=3911326
You guys should be smarter! If you want to warranty exchange it, flash the normal SPL again and flash a stock rom!

touch HD can`t align screen ?!

the cursor moves but putting me back to align again.
does someone can give me : [HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH]
"CalibrationData"=",,,,, "
Thx
My device has the following settings 516,534189,886196,192833,189836,887
But these are individual settings. To my mind you have to align for your own.
Are you sure you did it with the key? i have heard from ppl using their finger to align

tnx for your reply.
Cant align at all even with a stylus or finger
tried your settings tho, doesnt work. strange isnt it .
Well damm Touch hd .
align screen
I had the same problem but found I wasn't holding the stylus long enough on the cursor. You need to press quite hard and longer than a tap.
Sounds like your Digitizer is broken. This same problem (alignment loop) happened to my Dell Axim X50v a few years back.
The digitizer is what overlays the LCD screen to enable the touchscreen functionality, they can go faulty.
I replaced mine myself on my Axim, but I wouldn't void your warranty on your Touch HD, get it repaired by HTC as it will be covered by your warranty.
had exactly the same problem with my first one, was like that the day I received it.
I just got it replaced straight away no worries.
tnx for the reply`s
Still doesnt works.
pfffff It did work before tho.tried to edit the calibrationdata but it seems not to reply to that.also tried different roms.offcourse I made the welcome.not file in the sdroot.
Why?? Why???? ((((
made a new friend tho Mymobiler for messaging
can more people give their calibrationdata ???
I have noticed that every rom has his own data.
Tnx
What use is there in getting other peoples calibration data when you have a broken digitizer? Just send it in for repair, or get it replaced if you haven't had it very long.
your a right , always having the focus to fix stuff its a habbit.
Sending it out for repair tho .

Display broken?

Hey Volks,
Today i realized strange display issues with my HTC Touch HD. The ROM on it was original by the Provider (Telekom Germany) so i doubt it is a Flashing issue. I attached a screenshot for reference. Now my question: Seems this to be a hardware or software issue? Is flashing something that could solve this issue? If it is a hardware issue, would it be a good idea to repair it by myself? (i'm not complete stupid ) - What needs to be replaced? It seems that the touchscreen himself is working (pixels changing when pressing on the display).
Greetz,
Matthias
hi dude,
this seems to look like a hardware issue.
but..
i would flash a new rom or hard reset to check if it is software issue.
if the problem still exists after a reflash or hard reset, i would open your device and have a look for the problem yourself (its not rocket science )
you want to check the ribbons that connect the LCD to the motherboard.
(ribbons are clamped to motherboard so make sue you unclip the clamps that hold the ribbon in place, now check them for damage, dust or dirt)
be carefull though because the ribbons can break easily, trust me
after cleaning the ribbons, checking for damage etc, if device is still displaying like pic, i would buy a new LCD.
(ebay is the best place to go for a new LCD, it is best to buy an original LCD btw)
