[Q] Touch Pro 2 Screen calibration failed ?

Hi everybody,
I have problem with my HTC Touch Pro 2.
It was fully working until I damaged my LCD screen and digitizer.
So I ordered a new one LCD and digitizer from ebay. I changed old lcd and digitizer, booted up my HTC and everything looked allright. But problem came soon. Touch screen can't recognize my touch exactly. For example, if I click on something, digitizer solve it allways about 2-3mm higher. So I can't click on start, battery and every other click is moved about 2-3mm higher.
I made a calibration, but without any effect. I made a hard reset and than a calibration, problem still same.
And if try to make a new calibration (after first calibration after HR), I click on first cross (in the middle of screen), then up-left corner, down-left corner, down-right corner, up-right corner and nothing happens, I have to click on first cross again... and whole procedure again... So I have to make a HR and try to make a new calibration... still same problem.
Could anybody help me please? I'm going crazy, because I like my HTC and I can't use it anymore.
Is there any other way to make a calibration or how can I repair it?
ROM:
Energy.RHODIUM.29022.Sense2.5.Cookie.2.0.Jul.04.7z
(I have this ROM before I damaged LCD screen, any it worked fine)

It almost sounds like the screen/digitizer aren't lined up correctly... Just my .02.

Thanks for reply.
Ok, then It seems to be a HW problem between screen and digitizer?
So what can I do now? Try to repair it again?
How can I check, if digitizer is OK? or could be digitizer bad at all?

I'm just guessing from your description. I've never actually replaced the screen... If the two have to line up perfectly, I would ensure they are lined up correctly. Perhaps try slightly moving the digitizer down...

Ok, thanks. But I can't move with a digitizer, because it is in fixed position. Maybe I can move with a screen under a digitizer, but then I will not be able to see whole screen (digitizer has a black edge/margin/border).
Any other suggestion?

Nope, all I got. Calibration always works perfectly for me - if calibration doesn't work, there certainly must be some hardware problem. You replaced the screen, unfortunately you must establish where the hardware issue lies.

I don't have any help for you, sorry, just jumping on the wagon. My touch screen worked fine for a year but is now way off (1.5-2 inches sometimes) without having damaged the screen to my knowledge. I've switched roms (from MR.X to Mighty) and hard reset. If I try to calibrate it just keeps running through the process. Should I try to replace the digitizer? I plan on getting an iPhone if possible on Sprint in the coming month but would like to sell this for at least a little bit.

To both of you guys - have you ensured there's nothing between the screen or digitizer? Nothing that is wedged on the edge of the screen...?
I know some had reported complete screen failures just from some gunk that got wedged on the side of the screen.

Thought about that, but dismissed the tiny little amounts of gunk on the edge..currently searching for a toothpick or something small to clean out the edge. Thanks for the idea! Will report back.
Thanks so much arrrghhh! Found a small pin and got out most of the dust/gunk that was between one side of my phone. Apparently that bezel side is just a little bit looser. You saved me lots of time and money! Thanks. Always helpful on here and PPCGeeks.
Edit #2: Must still be more junk because the 100% functionality just went away. Time to clean it again

Broke my LCD, what are my options?

So I have literally no idea how this happened. I'm guessing I stepped on my phone while I was cleaning my room but the LCD had black and white stripes going up and down when I turned the phone on, and after a reboot my screen is completely black with a diagonal white stripe on one corner. However, the digitizer works fine and the backlight works. I'm able to answer calls and use the capacitive buttons. I found a replacement LCD through repairsuniverse.com for $35, and I'm wondering if this is my best options. Any G2/DZ users been through the same experience? Many thanks in advance.

I've done it before. It's not that bad. Make sure you do it slowly in a well lit area with clean hands. You've seen the video right? Make sure you have the phone separator tool or thick guitar picks

I am considering doing the same. Any updates on how the replacement attempt went?

Screen replacement warning

Just a heads up to anyone about to replace the htc one x digitizer lens, it is not user seperatable from the lcd screen, It will break at the weekest point which is the lcd itself,
damage will occur as shown in the video below (person in video fails to admit he damaged the screen during the recording)
I would go through insurance for ease or if you really want to replace yourself get the lcd and digitizer already put together on ebay as even lifting the lcd off the chassis will crack the fragile screen no matter how careful you are.

Haha he ripped the screen right off lol.

The maker of this video posted it here to a while ago and he did mention to order lcd+digitizer in one and not screen or digitizer seperately

Thanks i did not know that, me and my friend followed the guide (stupidly didnt watch the whole way through first) and his screen ripped apart at the same time as the video user, just letting other people know so they dont make the same mistake

Screen problem

Hi everybody I have a question regarding a screen problem I have.
Like I mentioned in an earlier post I accidentally spilt a lot of pure alcohol(the kind you use to disinfect a wound or something) on my HOX.
After a while the phone screen showed some strange grey shape on the lower right part of the screen and a bright white long shape looking like water jumping from a fountain on the left side starting from the bottom of the screen extending to almost the middle of the screen.After turning it off for 8-10 hours they grey shape dissapeared and the white remains and it doesnt look like it will ever go.
Strangely enough the HOX has no problem everything is working but I noticed that some apps are working somehow over the white shape covering it and some others like facebook seem to be under it making it visible.
I made some screen shots to show you the problem but stangely enough this white shape is not shown at all in the screen shots!!!!
Can anyone tell me where this thing might be?
LCD? Digitizer? elsewhere?
HTC funny enough suggested a factory reset to solve this and if that doesnt work(like there is a chance that it will...) to just send it to service.
I plan to play dumb to service hopping to fix this under my warranty as the phone has absolutely no scratch or anything anywhere as I never even dropped it once.
Do you think they can somehow find out what happened of maybe they will fix it under warranty?
Thanks a lot for your time reading this and I d love to have your opinions

Any photo?
Perhaps some alcohol got stuck between the lcd and glass...

Looks like overheating damage by a component beneath the screen, possibly something reacting to/affected by the alcohol.

When you say beneath the screen do you mean beneath the LCD as well or just beneath the glass?
I am just thinking that if its beneath the LCD it would probably not show plus the phone would have some kind of functional problem(it works just fine) wouldnt it?

Beneath the screen assembly. It looks like (possibly) some component or board has caused damage to or affected the digitizer, as your actual display seems ok.

So the service corrective action will be a screen assembly replacement or you think that something more will be needed?
Also if the digitizer was damaged wouldnt the phone use be affected?Cause the device has not been affected in anyway.
Everything works like it used to before this damage.

Send it of for repair, youll have to pay of course, how much tdo you like your phone?, that's the question.

I like my HOX very much otherwise why would I pay 428 euro to buy it?
Of course what makes the HOX stand out of the samrtphone crowd is the amazing display so of course I want it fixed.
I will try to cheat saying I know nothing about it(the phone doesnt even has a scratch) hoping waranty to cover this but if this doesnt work I ll have to pay 196 euro for screen replacement.
Although appart from that mark nothing else is affected I am worried that perhaps a screen replacement might not be enough if the digitizer is affected by something beneath it.
Do you think that a screen replacement will be enough to solve this problem?

HTC will give you the digitizer and LCD, especially if you end up paying, which will then get you a new bezel and unibody all still tapped up in protective coat, I've had it done for my phone, 160gbp.I even think you get the Onex+ version screen, gorilla glass 2.Could be wrong

[Q] white screen after digitizer replacement

Hi,
Ok I attempted to replace the digitizer on my LG G3 well the lcd was still good. After I took everything apart had to get the old glass and lcd separated. I did that but in the process the black front to the lcd (black plastic that is glued to digitizer) came off with the digitizer. Is that part crucial to the lcd screen working? Also I after putting it back together all I get now is a blank white lcd screen which comes on for a few seconds after holding power button and cuts right back off. Also when i put it on the charger now I get a constant blinking red led light and the phone starts to get really hot until pulled from the charger. Has anyone else experienced this before? What could be the problem?

I know I´m a bit late but I just experienced the same problem. Did you manage to fix it? Because I don´t want to spend about 40-50€ for a non-original display + digitizer.

Sadly, no. Since I got the digitizer for 6€ (paypal gave me 10€ discount) I think the easiest way is to get a LCD+digitizer.
