I had my Diamond for about 8 months now. All of a sudden no matter where I click on the screen it always clicks on the top left corner (Start button). I hard reset the phone, changed SPL but nothing worked.
My Specs:
Duttys 5.2.20764.1.4.3
Diamond-hspl-1.24
When I try to align the screen it keeps on looping not letting me get out of the screen alignment. I have to soft reset the phone.
Is my phone dead? Do I have to send it to HTC for repair?
sounds like a broken screen digitizer (the plastic which recognizes touch).
If its under warranty then i suggest you flash everything back to factory, ie. stock spl, stock ROM. Then RMA it back for warranty.
If it isn't under warranty and you wanna get it repaired. Then just order a new digitizer from Ebay and install it yaself. That will save you an arm and a leg, since HTC will probably charge you like 4x the price to get it fixed.
How come it responds to the screen alignment than? When I press the cross hair it responds to it and moves to a different position.
Right now I am trying to put the stock SPL on the phone but I can't get past the screen alignment. The is synced and everything. Any ideas?
You MUST change the ROM to stock first then the SPL
I did put the stock ROM back on the Diamond. But I can't get passed the align screen. I tried deleting the "welcome" file form \Windows\StartUp but the file is protected and can not be deleted. Is there any other solution of by passing the welcome screen?
I had this problem too, I got my Diamond from Rogers and went home. After a few minutes this started to happen, and I instantly went back and got a replacement.
I got same prob. But sometime it work fine, after i do softreset i cant skip screen align. Can hard reset fix this prob? im from malaysia, how much it'll cost to replace the digitizer? thanks
i have this problem too
hello all!
I had the same problem as you! after some time searching... found a program called "Remote Screen Alignment" ... and your problem is solved!
Just google it!

For the new diditizer is this easy to repair by myself??
I have a broken touch screen too (LCD is working perfectly, touch is non responsive, all over the screen)
I was just reading in another thread that changing the digitizer on its own is a bit of a nightmare as its glued to the LCD screen? Is this true, is this the case, if so, would it be possible to buy a LCD + Digitizer in one? I searched eBay but could not find anything?
Any help is much appreciated as the cost of a new phone is not an option!
Thanks,
DG.

Hi
My digitizer is also broken, I ordered new one from ebay (cost about 10 €) and as you wrote replacament is nightmare.
I'm trying to find a manual or instruction video but I cannot find anything.
If somebody knows how to replace digitizer please let me know or share a link for it.
Currently my best solution is to order new digitizer with display (cost about 20€) It is possible to order for exaplme here:

Cheers
hello, i have the same problem with my diamond here, pres the screen and it activates the left upper corner, after a while stoped doing that but not my right lower part of the screeen doesnt respond. i mean i press the "j" and it writes "k".. u know what i mean., i cac calibrate the screen but after 1 min the problem is back. i wanna buy that digitizer and change it but b4 this i need a confirmation, did anyone do it and after that their diamond worked like b4? waiting for reply thx
This post is giving me a nightmare. I am facing similar problem only its not permanent. What I mean is it woks fine sometimes but wont respond sometimes. Sometimes it responds in the corners if I press hard. I think my phone is just passed its warranty also its 2nd hand though I have the bill. Service centers are really bad so I am scared.
Do you'll think my digitizer is gone bad or is it a software glitch?
Hi guys
I have a similar problem with my HTC Touch Diamond,
The screen just gone crazy constantly pressing on the top-right corner, this happened like 1 week ago. After searching the internet and this forum I found out that my only quick solution is to hard press the four corners to get working properly again but the problem will come back again after a while.
I bought this phone from ebay in 2008, had no problems with it untill I found out this ugly strange colored square in the middle that is noticable after switching phone's backlight off, I guess that was due to me holding the phone in my jean's back pocket (as I used to previous phones non touch ), I had this phone working perfectly until what happened last week!
I decided to find if this is a software related issue, so I upgraded to official HTC ROm 2.03.405.3 WWE, but the problem persists
I also bought a digitizer from ebay in case I want to replace it (but never done this before)
Can anyone please confirm if I am still under warranty, how to check this and if yes is that going to cost me anything to get it returned to HTC for repair (other than postage costs of course)
If not under warranty anymore, do you advise me to get a LCD+Digiztizer combined instead ?
Many thanks !!!
Damian
I have this problem (not my video):
youtube > watch?v=5-IUzerAT0s (sorry, I can't post links)
Problem:
Sometimes, and really just sometimes, no matter where I touch the screen it only signals a left touch. So wherever I touch, 1, 2 or 3 - only 1 will enter.
I am not sure if this is related, but it may give some clues:
A few days ago I disassembled my Diamond. I did not take out the LCD coz it's sort of glued in and probably hard to take out and may break.
However, I got down to the digitizer soldering. I did not de-solder the flat-cable, but I pressed my solder iron on each of the 4 solder joints. I pressed the solder tip right on the film. Don't worry, it's most likely polyimide and it's heat resistant.
After that the Diamond worked well, well, for a few days. Then same happened again. When I have the problem and I press strongly right of the HTC logo (LCD bottom right) the problem disappears. That makes me thinking the problem is maybe mechanical.
It maybe a solder crack. I presume the Diamond is RoHS, and my solder iron was not RoHS. That matters, coz RoHS solder needs more heat the lead solder. Means, my solder iron did not really melt the solder under the film.
I will give that another try with an RoHS solder iron in the next few days.

I have the same 'tendency to go left' problem. From my experience, I found that the problem could be caused by heat. Here are some examples when it goes wrong: When I use Tomtom navigator while charging the battery, the phone really heats up and starts to go 'left'. When I try to text message under the sun after taking it out from my pocket. When I have high usage such as wifi + opera. Really hop somebody can come up a solution for the problem...
The Reason ---
Its a heating issue seen in 20% of all shipped diamonds. It heats and expands the digitizer causing loss of touch.
Solution ---
I'm working on it!
P.S - The heat i'm talking about is not the heat that's generated wile using the phone , its due to outside exposure.
Crazy thought - Try it at your own risk
Exposing the mobile to moderate temp (cold , say 12-14 degrees) might help. Not sure.. i said MIGHT.
Don't try this if its under warranty. And don't blame me if you did something wrong and all you circuits get messed up!
Anyways will post if i hit something on the way!
No, new solution??
Maybe change the digitalizer solves the problem?? Because two months ago the problem only stay few minutes but now i can't make the alignment process.
Thanks!
I have searched for solutions for the past 2 days but cant find one, if i missed it or this post is redundant , i apologize in advance.
Now my tilt is driving me crazy. It started last week when The touch screen wasnt working, but i fixed it by doing a couple of soft resets. then all the sudden, everytime i slide my keyboard out, the touch screen would stop responding. this went on for a day, then yesterday, when i tired to use the keyboard, the screen went blank, like the light died or something. but when i put it back on portrait, the screen would light up again.
A few moments later, the touch was responding, tried to use the keypad then the screen went blank..tried soft resets about 5 times and uninstalled all recent added programs (skyfire) ..finally the screen was working but the touch still wasnt working.
So this morning, i had the bright idea to do a hard reset....dumbest idea ever cos now its stuck at the screen where i have to "tap the screen to set up your wm device" and guess what..the touch screen isnt responding
plz i really need help with this. all so , i have a broken tilt.., well lcd screen is cracked...can i try to dismantle both tilts and replace the screens?
Ok, i used Code Factory's Remote screen alignment to bypass the alignment, but if i cant use the touch screen or the keyboard, the phone is pretty much useless for sending any information or making calls..is there a way to fix this?
I have had this same issue with my tilt. I could use the scroller on the left side of the unit to navigate but no touch screen. Both times that this has happened to me I removed the screen protector that I had on and restored a backup that I had on my storage card (I run a backup weekly). This has always fixed my issue. You could try another hard reset, not sure if that will help but do you get any lights on the keyboard when you slide it open? Is your tilt less than a year old because there is a manufacturer's warranty too.
Jim
when i slide the keyboard, i do get lights on the keyboard but not on the screen...it just goes dead..but when i slide it back in, the screen comes to life.
I cant do another hard reset cos i have to input the "1,2,3,4" code.
Also , the phone just got out of the 1yr warranty this month...awesome
I want to buy a replacement screen with a new digitizer but i need to be sure that is the problem.. ive searched for this keyboard problem but still have no answers
Now I'm having the same issue, touch not responding. I first noticed it about two days ago, when I slide the keyboard out, I could type just fine, but when I went to send the message the touch screen wouldnt work, so I'd close the keyboard and it would work. well yesterday it stopped working all together, so i used my d-pad and did a sprite restore and it started working again. But then On my way home i hit the lock button, and it stopped working after that, and I couldn't get it unlocked. I used the inner soft key to hit the first part of unlock, but then I couldnt ever figure which button to hit to get the on screen part of the unlock. So I had no choice but to do a hard reset, and just like highoct now I'm stuck on the stylus setup , and the touch still doesnt respond. does anybody esle have any suggestions ? Thanks in advance.
You can use the Code Factory's Remote screen alignment to bypass the alignment.
If the touch screen is the only problem, you can do one of two things if you are no longer under warranty;
1. Fix it yourself. You will have to buy a new Lcd screen with new digitizer at ebay and use this site http://www.pdacenter.ru/razborka/razbor_htc_kaiser/ to open up your tilt and replace it
2. Send it to a repair shop, I had two tilts and sent the one with the broken screen to www.missionrepair.com got it back in a within a week, $89.00 plus shipping
here is the link : http://www.missionrepair.com/Mission_Repair_AT_T_Cell_Phone_Repairs_and_Upgrades_s/321.htm
I still have the same tilt with the original problem..havent found a solution yet
Oh yeah, I did manage to do a hard reset again, but now the screen is just white. I can hear the sound of it booting up but it still has a white screen. I tired going to the Bootloader screen ( Camera and power at the same time)...still have the white screen. I believe its a hardware problem but i don't know what it is...any ideas?
Ok now I've done a hard flash, using the same HTC kaiser rom 6.1 and it fixes the problem for a little bit, until the first time I slide out the keyboard , then the screen stops working again, any suggestions ?
iPhone 3G Screen Repair...finally an affordable answer
If you are reading this, you are most likely in the same dilemma I was in. I dropped my phone and picked it up only to find out that the glass screen was cracked. I took my broken phone to apple and found out it would cost me $199. I then was told about iPhone 3G Screen Repair. They offered the iPhone 3G glass screen repair for only 69.99. They repaired my phone the same day they received it. I was very happy with the repair!

I know this thread is a bit old but was searching d forum for possible solutions cos yesterday i developed the same exact problem on my kaiser for no apparent reason!..flashing it hasnt helped and now im stuck on the wm setup screen..when u say u still have the same tilt with the original problem do you mean that the repair was unsuccessful? have you tried reparing it yourself? Thanks
I just started to have the same problem, it started out with the touch not responding (which a few soft resets fixed) and now the whole screen doesn't function unless i slid out the keyboard or if i jiggle it around and open it a couple of time i can usually find a spot that allows the screen to function with the keyboard closed. If i leave it in this position for about an hour the touch starts responding again, wtf. This is very inconvenient because as soon as you move the screen even just a little it will take me like half an hour to find the position which allows the phone to function.

same thing happened to me 3 days ago. touchscreen has just stopped responding.
it still worked when i slided my keyboard out, but only when it was out. then i realized it won't work at all (!) after soft reset. however, i could make it work again like that when i did the soft reset with the keyboard out. weird.
i tried searching, and decided to make a hard reset, flash a new rom, etc, etc., but no more touchscreen. at all. the device doesn't feel any touch in any case. nothing. i bypassed the beggining tap here with the storage card trick. (i've read it somewhere on the forum).
now i can only use my kaiser with the hw buttons, the keyboard, and that's it. no touch. really weird. please if anyone has any updates, solutions, anything, post. sniff sniff
mine doesn't have anything on the screen unless i slide it out, if i have it closed anymore, it just doesn't work at all.
try this:
ive just replaced my barely functioning lcd by myself, after living with it sometimes registered the stylus jumping around when i used the stylus. but before you change your lcd, here is a couple of tips for you guys:
1) try sliding out the keyboard. hold one finger in the middle of the keyboard and another on the back side of the phone, and squeeze hard, but careful. it might be that the flat cable between the screen part and the main part has loosened a bit from its socket, this could help it back in.
2) try sqeezing the hang up button hard. this might help the lcd-cable correctly back in its socket if it is loose.
im saying that this MIGHT help, if youre lucky. most likely you have to open the phone and squeeze the connectors back in yourself, or actually change the entire lcd. anyways, let me know what works for you!!

well, i tried both tips, but they didn't work. i'd like to say a big thanks anyway!
then i grabbed the kaiser service manual and took my device apart into pieces. i reconnected pretty much all the cables and stuff, but still no touchy. any further ideas?
you should try replacing the screen. im happy to say that this screen from this seller on eBay worked for me: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250539984183

I need some help/questioned answered and am hopeful someone here can help
I am trying to replace a broken touch screen on an att tilt but when I replace it with a new screen and turn on the phone, the touch screen doesnt work. Is there something special I need to do? ie software update/hard reset? Or on the touch screen there is the flexable cable the wraps around to the back of the lcd with 4 connectors, is there a special way of attaching it? ie glue? it looks like the old one was just held done with tape, but I did the same thing and am wonderingh if it is connecting. I can upload photos if you dont understand what I talking about.
Please someone/anyone help. all suggestions are greatly welcomed.
I am in a little bit of a rush so I dont know if I explained everything clearly, I hope so
replace lcd
Hi, I replaced mine and there is just a ribbon cable that plugs in...it can be kinda tricky but basically you just line it up and slide it in...Theres a couple of threads on here with detailed instructions you can find by using the search, thats how I learned how to do mine. The only thing I had to do afterwards was the touchscreen alignment function that you normally do when first installing the OS because it seemed my touchscreen was slightly off..after that it was fine.
Hello, I am a true noob so please forgive me if I sound dumb.
I had a broken screen so I bought a new one on Ebay. I changed it perfectly, it looks good but now when I touch the screen it acts like I touched the top left corner (in portrait)no matter where on the screen I touch (so it opens up the "Start" menu). In landscape it acts like I touched the top right so it opens up the drop down menu with all the running programs.
I would really appreciate some help. I try re-aligning the touch screen but it does not recognize any touches at all. I have to soft reset the phone to get out of the re-align program.
I don't want to hard reset because I have read many cases where the phone gets stuck in align program as it is trying to setup and they have to install remote access or something to get around it.
I would like advise on whether it is the new screen or the phone. Is there something I can check for inside or should I send the screen back for a replacement.
Thank you for your help.
Having replaced the touch screen in a Palm with success, I would say that...
You either have a problem with the connector for the screen, recheck the connection
Someone sold you a bad screen.
Something else is wrong with the device.
At this point I don't know that in your position I wouldn't do a hard reset. What is the worst thing that can happen? The device is already broken in it's current state.
Good luck.
Thank you
Thank you very much for your help. I will try the connector. if it does not look damaged then I will return the screen.
Did you replace just the screen itself, or the screen and the digitizer? More than likely your digitizer is broken aswell. If you replaced them as a set, request a new one from wherever you got it, and if you just replaced the LCD, then you need to buy a digitizer aswell.

Well, I only received the screen. I cant figure out where the digitizer is on the tilt so I don't know if I changed it or not. Does any body have any picture??
I think I read somewhere that it all comes as one piece(the screen and digitizer), but I can't confirm it.
Indeed they most of the time do come as one peice, so if your connection is good on the mobo, then I would say that the digitizer you recieved is bad. The digitzier is the super thin peice of glass that covers the LCD screen.
Well, I fixed my old broken G1 with new screen, touchscreen panel, case and keyboard.
Now I have 2 issue:
1) Sometimes my touchscreen goes grazy!! If I use the touch test application I see that sometimes when I touch the screen in an area there is another virtual touch in another zone of the screen. I read that it can depend from the current source when I charge the phone.. but I'm going crazy!! I opened my phone 10 times (I thought there was a problem in the cable that link TouchPanel to LCDPanel, because when I lock the cable with the clip it tends anyway to go out from the connector, now I put some scotch tape to fix but the problem is here.. so I think is another problem).
2) My volume rocker doesn't work!!
I bought 2 new keyboard to fix this problem, but no one of that fixed the problem. I thought the first new keyboard had volume keys broken, so I bought another one, but the problem persists!!
Now the Touch problem rarely happens, but the volume rocker is completely unusable..
Someone have experience about G1 assembling/repairing ?
Thanks and sorry for bad english
if you have put in multiple keypads have the same issue i would assume that it is the connection going to the motherboard. just a guess there but its either that or you have had a bunch of faulty keyboards.
only other thing would be a software problem
does the keypad work in recovery (let you go up down throughout the list) ?
as for the touch screen, probably need a new digitizer or flex cable, both are cheap and it sounds like you have the knowhow to replace them.
Ok, but digitizer is new!! screen also is new, and I have bought a total of 4 flex cable because I see that they are fragile (I broke the first I bought).
I tried to change flex cable but the problem remain the same.
The only thing that can be damaged is the LCD cable that links to the flex cable: it has a small cut where the cable have a curve, but the cut don't reaches the contacts (the cable is transparent). I also use some glue and scotch tape to mantein lock the cable.
The digitizer cable is connected to the LCD cable, and then they go to the flex cable that connect them to the motherboard.
The strange thing is that seems a software issue, because if I turn off and than turn on the screen, the problem is fixed for some seconds, minutes and sometimes hours...
Another strange thing is the possibility to control the screen with some metal objects from the moment that the virtual touch problem appear (I can control the screen also without touch it, with hand and piece of metal)
video:
have you tried a factory reset if you think it may be a software issue? if that dosent work you can try install a whole new rom.
really it sounds like it isnt the hardware since you appear to know what youre doing. i have a had a few phones that had screen (digitizer) issues and a new rom flashed cured it just fine
since you dont mind putting a few dollars into it, and your familiar with the inside, you can always try to pick up a cheap motherboard or spare phone from ebay or what have you, then swap the motherboard and you could then hopefully find out if it is the hardware or software

Huh sounds like you got a cheap digitizer than. Most good digitizers use heat to touch. If it's literally touch, then sounds like its a fake/meh digitizer. i hate the digitizers that aren't heat, but press. I see them all the time in those first samsuck touchscreen phones. And they usually die in a bit. I had a Samsung behold with a screwed up digitizer

Yes I flashed 3 or 4 roms after a wipe (I tried also super-wipe.zip), but the problem is here..
The digitizer works well some times, but sometimes get crazy (you can see in the video).
I don't that my new digitizer is fake, but I really don't know!
BTW I'm trying to repair my phone for fun (now I have desire z) and because I am fascinated by my old G1.
PS:
I see another strange issue--
If I touch the screen when the phone is on a table the screen digitizer is not very sensitive and can't take input from fingertips.
If I touch the screen when the phone is in my other hand, the screen digitizer is a lot more sensitive and it take input from fingertips.
My impression is that there is an electric field or something similar that disturbs the digitizer, and when I take the phone in my hand I discharge that field to ground. Also when I turn off the screen, seems that the electric field discharge so when I turn on the screen is ok, but after some seconds the field returns to disturbs the screen.
I really don't know, but is the impression that I have.. something that is not shielded.
Now I'll try to use my phone in airplain mode.
Thanks guys, I'm happy to see that this forum is still very active
