HTC Diamond Strange Screen Problem (URGENT)

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:

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!

screen problem, most of the time do not work

Hi, i think i have problem with my screen, it's not work anymore, so I decided to reflash device with official Rom. But it didn't work.
Moreover before windows system start for the first time ir requires to tap on screen to boot. So now I cannot use my TytnII at all.
Is it any options to boot it without tapping on screen?
Or just to flash with other ROM, but HARdspl is not installed so a bit afraid to brick my phone. please help

install hardspl (same procedure as flashing) and then install rom of your choise if it dosn't work have you done any of the following
dropped it in water
gone in the washing machine
etc.... stuff like that

why don't you get a new digitizer??? it's $10 for kaiser?? i've been changing them like underwear...every half a year.
what is it, what's asking you to click on screen? if it's just a welcome screen, put welcome.not file in root.

hehehe funny expression 'changing them like [email protected]
what do you only change your underwear 2 a year

hehe, i live in Lithuania, so price with shipping will be around 25$. I think this isn't very cheap. Finally got screen working, but after 30min of using again no respond to tapping, then again working fine, and after that again no. it's annoying. I think it's problem with digitizer? I haven't it dropped to water, it almost brand new

thats good you got it working
hope the problem doesn't happen again

if we assume the problem is harware, it would most likely by at one of two spots.
place, where the ribbon cable is soldered to lcd
or place where two piecies of digitiizer are connnected to each other.
might help if you check on the ribbon and glue a plastic tape all around the edge of digitizer, making it press little bit more on it
well, if that's hw probllem. but first you shoud try different rom. you can reflash without digitizer working. and check for pocket controller or similar if you want you can control pda from pc with it. there are two free and Pocket contr is trial.

if you just want to bypass the "tap here to use your device" message on the first boot up, search for "welcome.not".
create a blank file named "welcome.not" and place it in the root of your sd card and then power on the device for first boot up.
make sure it is a blank file. make sure it is named EXACTLY "welcome.not". if you are doing this with your windows pc, make sure you have turned off "hide file extensions of known file types". otherwise, the file might actually be named "welcome.not.txt" but might show as "welcome.not" on your pc.
search about it for more information.

hi, have tried differnt rom, but problem still persist. screen is not working, but sometimes it starts working very well. but most of the time it not respond. when backlight goes out and touch screen it starts to light but can't touch any options on. So what can be the problem, only digitezer or whole screen?

it was more probable it would be hw. but we need to eliminate all possibilities and reflash was easiest.
Still there is more things which could be the problem.
And there is no way to tell for sure what is it.
Did you say the pda is new? or digitizer?
And then you said when backlight goes off, digitizer will stop working, but still reacting on touch (to light the backlight) Is this right?
When will it stop / start working? Does it change if you press on body - case?
Does it change if you slide keyboard out or in?
There would be a short test each time pda/screen is powered, if digitizer fails in this test, it would be ignored till next test pass. Could this be your case?
digitizer could be broken on corner, or has bad contact inside
- You can test it, if you'll solder test wires on it and measure resistance, which should be around 500 ohms without touch and going down on each touch, can't go higher! test for both H & V
but the same reaction could be if ribbon cable connecting two parts of kaiser is broken (or connector on mobo side)
but if it's new it shouldn't.
and at last there could be problem on mobo. inside the controller chip or on it's connection, soldering. But not very probable.
It definitely looks like bad connection somewhere. You need to find out where, so you'll not buy digitizer if it's good or ribbon cable.
Put plastic tape around digitizer inside, as I wrote before, inspect ribbon cable and digitizer and it's connections. Try to locate event when it goes wrong.
If you'll not open it and check on these things, then maybe get a new part which will show bad, then I don't see how more we could help you.
You can use it without touch screen somehow or get a new phone.
Digitizer is US$8 with shipping to Lithuania. That's really cheap, even for us from central european countries.

and ribbon cable have fair price too,

papo very informative
All i want to add is that it's easier to replace the whole screen with a digitizer already on as the digitizer is very hard to remove since glued to the glass more than likely will get wrecked and not able to replace new, whereas full kit wont cost a lot more and will be less stress just 4 screws on the back plate of Tilt "where sim door is".

Well, it is not new, i've bought it from one girl, but it's like brand new, no scratching at all, very good condition.
also, yesterday i checked all the connection inside it, but the problem persisted.
I think I have understood what kind off problem it is...when remove sim card it stars to work perfectly. When insert sim, it work some time very well. Then again screen start not to respond, any ideas?

mm, I know some pretty good spells, but you need a magic wand to make them work. If you don't have any you need to:
tape the screen as I wrote before (half millimeter tape),
if no help, hardwire analog multimeter on digitizer and test it properly (while pda off and open) as I wrote before
tape bended paper across connector on mobo.
OR just get a new digitizer straight away. it's $8 and pretty good chance that it's the issue. it's maybe 50% chance but what I mean is:
You have $200 phone (now on market) let's assign it 200 points
It's working on 20% with digitizer broken, now you have 40 points
digitizer 8 points to add. With 50% chance to fix = 16 points to add
result: by adding 16 points you gain 160 (200 - 40) that's 10x gain = good risk

WTF with my screen? post photos. on the first my screen, on the second lcd screens which are beiing sold on ebay.
I decided to buy new digitizer, but when looked at my screen, it realized have completely different layout where digitizer is connecting to screen. Am i right? Is the digitizers which are sold on ebay will suit my screen?

that's fine. they all work. They are not oem but works well. Maybe not so scratch resistive.
You may get the digitizer solo, but they will not include a special double side tape which goes around and is holding it together. You can make that tape, but it's pain as stylez said. A lot of cleaning the used old one, then cutting small strips of ds-tape. and you need to put a paper or something in between two layers of tape as you need a little space in between. And then soldering that ribbon. Better just get whole assembly.
==
I see you tried that tape, before you buy it, try the last thing. The place where digitizer is soldered to lcd modul.
On that piece you sent photo of, you need to open back cover.
check the picture:
1. peel off antistatic tape from connector, from up -> down
2. take cover off
3. there will be attachment of digitizer behind the cover, like on your second picture.
Check for good connection
AND
check if soldered pins could not be touching the back cover you took off
( i had this problem once)
put electric tape accross it a give it a try - that will isolate it from back cover & make a little pressure if bad connection

X1 felt down --> no display

Hey
A friend of mine called me yesterday if I wanna buy his broken X1 (it felt down :/) and repair it, because I'm the man for such jobs
Do you think it's only the LCD-flex-cable or another repairable damage?
I think I can get that device for 2-3 days and then decide if I buy it...
Some ideas? Is there any chance to repair it?
Thanx, Carbon

yes, probably even a loose connector on flex cable
Hello,
I am quite certain it is an easy problem, i have seen many x1 phones with just a minor loose connector which causes the screen not to respond.
The best way to check it if it really is just the screen/flex cable is to turn it on, and check if the side lights flash in all colors.
If that works the phone should work normally. (even if the screen doesn't work)
After opening:
Re-insert all the cables in the screen flex cable and check if it works..
if that doesn't work then replace the flex cable.
If the screen works:
Then check out the screen if it has any crack's or black spots.
In that case you will have to replace the screen/touch screen also.

Generally, if there is no physical damage to the LCD itself and the phone buzzes on startup with all appropriate sounds - replace the flex. Flashing lights are attached to the flex and are positioned ABOVE the LCD on flex connection, therefore will not light up if the flex is damaged and neither will the upper keypad and other less obvious things.
The flex replacement is not minor, just be aware of that. Bad falls are also the reason for main PCB damage, in which case there will be nothing you can do.

Thank you so much
It was a "very short" call by this friend, but when i take the device, I want a precise report what happened...
atm I don't now if the sidelights show reaction, but I will report
I'm afraid of a real PCB damage...

In flex problem side lights will not light up, as i mentioned, they are positioned above the Lcd connection, so if the main flex connection ribbon is damaged, as is most often the case, all of the upper level functions will be gone, but you will get a startup with buzz and sounds present.

I got it
And LEDs are flashing and you can start it complete normally, but you see nothing... i'm going to open it and check the Flexcable

Hardware assemble help!!

my G1 was destroyed in a crash, so I buy new plastics+keybord+slider (all plastic parts) to assemble the hardware in the new cover.
All is going well, but after the boot I notice that the touchscreen is unusable... if I touch the screen it begin to slide or press random points that I didn't touch, for some seconds...
The touchscreen is going crazy!!
I tried to open again the G1, reconnect the cables of screen/touchscreen and restart android.. but I have the same issue..
What the hell is happening?
The touchscreen panel seems ok, it doesn't have deep scratches, and it seems that the fall has not damaged visually the touchscreen.
It is a link problem or touchscreen, or what??? Someone know?
I don't know what to do.. buy a new touchscreen for 20€?? I spent 20€ for the plastic, if I don't solve I would change device.. but the qwerty device in europe are not so good
I'm waiting for milestone3, or a samsung/HTC qwerty device with dual core and screen> 3.7"
Please help I don't want to bury my G1
EDIT:
I found this video that show a similar issue on the motorola milestone.
It is really similar to my isssue..
http://www.youtube.com/watch?v=_PNuXREuDxA
I'm thinking that perhaps touching the back of the touch panel I spoiled something, or something like that (perhaps I have to clean the back of touch panel with somthing?)
I'm going to try something, all reply are appreciated.

I find solution (hope)
The problem is the bus cable of touchscreen that is damaged.
I bought a new cable, I hope to solve this problem.
Sorry for this useless thread

HD2 Repair

Hey guys,
The USB port of my HD2 broke off and I was forced to replace the motherboard. When I assembled the HD2 again, I could immediately see that there was something wrong with my screen. The screen couldn't display full color (only bright red/orange/white/dark green/cyan accents). Also, the 'hang-up button isn't responding anymore after I replaced the motherboard (and flexcable).
What happened? Is there something wrong with the lcd display or did something go wrong when I (dis)assembled the phone? I took the motherboard and the flexcable from another HD2 that had a broken display.
Thanks in advance.

So you completely voided your warranty through HTC and tried to fix the device yourself, then screwed it up. I'd still say send it to HTC and ask for a repair. I don't know if they'll do it or not, unless you used official parts. I know they do out-of-warranty repairs, but they'll charge you.....

Yep you screwed up the repair, those ribbon cables need a delicate touch & any handfisted moment ends up with what you have got now ...
Another careful strip & inspection of all ribbon connectors is needed ...

I bought it as a second-hand phone. The guy didn't give me a reseat and the HD2 was flashed a WP7 ROM.

For the button problem, how are you turning your phone on without that button? do you hear/feel it click when you press it? If not its just misaligned.the buttons are on a flex ribbon cable with two holes on each side. it fits on the plastic middle frame of the phone which has two small spikes coming out of it... it has to be perfectly placed for your buttons to actually click..
if the flex ribbon is broken however you can buy one off ebay for arround 10$ any will do, mine is not original works fine..
for the screen you could have messed up the lcd, did you separate from the glass-digitizer? if you did you probably screwed it up.. its not a easy thing to do.. also was not necessary for your repairs
the connection to the motherboard might not be all the in and clipped which might cause your problem... (being that two of the little pins provide voltage and ground while all the others provide data information if one of those pins is not in all the way a piece of data might not be displaying for example a color. Never seen that happen its theoretically possible thou)
well I have only opened my phone 3 times and dont claim to be a expert.. but this is my take on it... Good luck!

@pablow Thanks for the detailed response.
The HD2 is only turned on, after I place the battery. Otherwhise it won't start.
I hear a click on the (broken) 'off' button, everytime I press it. I also noticed that the inside of not all of the 'spikes' are empty. I can see a bit of the flexcable in the spike of the broken 'off' button. The spike of the (working) 'call' button is empty.
I think that the flexcable hasn't been connected securely to the motherboard. I'll try connecting everything again tonight.

not that it makes much difference but HTC wouldn't of fixed it through warranty because of usb damage anyway

I thought so, thanks for the heads-up anyways.

[Solved] Display is fixed
Update:
I disassembled the HD2 and reconnected everything (from coax to flexcable). Fortunately it worked! The display is how it should be.
I have another problem now. All of the buttons don't work now, exept for the dial button. Do these buttons break so fast? It's annoying as fuark, because I have to disassemble it another time in the future to fix the buttons.
I also couldn't re-attach the volume control tab when assembling the HD2.
