Wrong Digitizer? - Wildfire Q&A, Help & Troubleshooting

Heya Guys.
Well Someone Stood on my HTC Wildfire. So after a while I got around to buying a new screen for it, The Screen arrived yesterday and I just got around to fitting it, when I removed the old one I noticed that it is lacking the I/C Chip, and that the new one I bought has this IC chip.
After fitting the new screen I cannot get it to respond to Touch(as I kind of expected what with the mismatch) however under HBoot, instead of having Touchscreen:Fail, It reads the Touchscreen as being there. If it detects the screen, is there anything I can do to make the phone work with the new screens touch? Possibly updating something somewhere? Or flashing it?
Thanks guys.

Can't allign my screen.

Hey guys!
I'm experiencing a very strange and annoying issue with my BA, and I was wondering if I could get some input from you.
So, here goes:
The touchscreen (not LCD) in my unit was broken, and thus I decided to fix it. I purchased a new one off eBay a few weeks ago, and just yesteday I proceeded to install it. To my surprise, something seems to have gone wrong.
I power up the unit, make my way into "Allign screen", and then the last "cross" that I have to touch rarely clicks in. On the other hand, when it does get detected, it simply restarts the alligning process.
What I've tried so far:
- allign right after installation -> no luck
- hard reset (on WM2k5_v4_R2.1) -> no luck again
- opened up the unit again, repositioned the screen -> nothing
- upgraded to Logout_WM2K5_5.4.03_HN -> still nothing
Right now I'm out of ideas, and I was hoping somebody here has some. Do you think the new touchscreen might be flawed ? I'm already discussing this issue with the seller.
Thanks for reading
New touchscreen or a refurb? Same type? (toppolly / sony) Sounds like it's been stripped from an old unit to me as it's not recognising the taps in the right places - can you see somehting like a liquid spill anywhere on the panel? This is what it looks like when the overlay touches the glass.

That was in fact my auction. Looked like brand spanking new to me, not one single stylus mark, and also had the protective sheet on. Of course, I might be wrong
Also, no liquid spill visible anywhere.

I bought from him also and am yet to fit - I got the completley wrong module :-(
Richard
What do you mean wrong module ? The "tip" of the flex cable ? Mine seems to match with what was already there ...
Hey NSD!
I purchased the exact same module for my Himalaya device, after the touchscreen being cracked.
My father, who is an electronic engineer, soldered the flat wire from the touchscreen onto the rear side of the LCD with normal copper wires. Unfortunately I have the exact same problem a you!
After attaching the entire LCD (+touchscreen) onto the mainboard, and supplying power from the battery, I'm not able to go past the Align Screen section!!!
The touchscreen is from the manufacture 'Asian Media' (I think so...).
It can't be a coincidence, that both of our touchscreens don't respond to tapping!!!
Anybody been able to get this problem fixed??
Any help would be appreciated!!!
Kind Regards,
Tony Schattat
I never replaced the touchscreen of my BA but I have replaced the screen of my ex ipaq 6315 once.
And one thing that I know is that sometimes the screen align process is different from the normal, I mean, it keeps repeating and repeating again many times....until the unit finally passes the align step and finishes the configuration. Actually I´ve "aligned" the screen more than 30 x (when I replaced the screen).
It happened just once and then I had a completely normal unit.

Replaced desire AMOLED screen - Still blank

After dropping my desire the screen had an obvious crack (no crack in the glass/digitiser) and displayed crazy colours from the crack, spreading across the screen over the course of the day until finally going completely blank.
Bought a new screen on ebay, same part number, same samsung AMOLED. Replaced today and the phone exhibits exactly the same behaviour. Switches on, digitiser works to the extent I can unlock and lock the phone, but screen is constant black. After a few switch on/offs the screen showed two green lines at the top and about half way down upon unlocking, that went away after another lock and unlock.
Pretty confident that the disassemble/assemble went ok and I didnt stress any flex connectors or similar... so have no idea what could still be wrong....
As I say, phone boots and can unlock/lock (makes the right noises etc) and is recognised by computer when plugged in.
Could using the phone until the screen completely stopped working have broken the controller or something?
Any input greatly appreciated.....
EDIT:
Just switched it on again, green line at top from keyboard lighting point, then the whole screen went blue on unlock. :S
This sound like a dying something, or maybe just bad contacts? Find it strange that unlocking has an effect....
Might be a bad connection or little shortcut?
Here is an official video on how to assemble and disassemble the device, http://forum.xda-developers.com/showthread.php?t=768535. Don't know if that helps but you can check if you did something wrong in the progress.

Seeing as the part was shipped from my country and had the exact same markings and serial numbers as the part I removed, I dont think this is the issue.
Thanks for the video, will disassemble and clean all contacts later today.
Was mainly posting to see if people had heard of/experienced the same issue, trying to ascertain whether it could be a faulty replacement or if its possible to break the hardware that runs the screen.
A good fake can be hard to tell apart from an OEM part...
So the consensus is that its a fake replacement? Really? The screen seems identical in all markings and connectors, my only conclusion can be it came from the same factory. What market would there be in producing defective replicas of mobile phone components?
Anyway I have sent the screen back to the seller for a replacement.
Any response to my other questions? Is it possible to damage the hardware that drives the screen by using the phone with a dying screen to the point of blank display?
Reading through another thread: http://forum.xda-developers.com/showthread.php?t=933866
Post #6 suggests the rom on the phone could have an effect, is this the case?
Thanks for any input.
Rom couldn't be the issue if you've installed the exact same screen.
My guess would be a loose connector.

My desire lives!
Replacement screen worked just fine....
Thanks for everyones responses!
Can you post the link to the seller on ebay, from whom you bought the display?

Screen replacement question

I need some help all, a year ago I bought an evo with a cracked screen and somehow when I took apart the evo I chipped a small micro chip that is on the board. I think its a chip. anyways. in the picture you will see i've showed that chip with a big Yellow arrow. After putting on the new screen the phone just boots to the lock screen and is not responsive to touch. After 10 seconds or so it just reboots and does this over and over until I pull the battery. Does anyone know what that little micro chip does? Could it be replaced? is it the reason the phone is not responding to touch and boot loops? Any help is greatly appreciated.
So nobody here knows if this chip is why my evo is in a boot loop after it turns on?
even if you could find that chip, it's very unlikely you or anyone else would actually be able to replace it.
If you managed to damage that chip during a screen replacement, you have essentially broken the chain of data through the board. Your best bet would be to find a broken EVO on ebay or something to get the chip from a board. However like the previous poster said. Good luck replacing it.

If your Touchscreen/Home buttons are not working (Probable Error)

About two months ago, my screen decided to die. I ended up getting a new phone, but I still had my Play sitting here bothering me. So I decided to get to fixing it.
When I tore it apart, I thought that the digitizer had died, but what I found was actually the connecting the digitiser, LCD and Buttons together was damaged.
So I ordered one on ebay for about $10. When I got the cable, it seemed to be about 3-4CM shorter than the OEM one. Which supports why I think this may have been a design error on Sony's part. What was happening was Sony's god awful mechanism for sliding the screen up and down had pinched the cable, and caused it to be damaged.
I know this might be a longshot, but I think that some people might be able to save a dead device by replacing this one simple part, I know it worked wonders for my play, as well as a friends.
I will post a link to the part as soon as my post count is up.
So not the digitalizer?

I am having this problem as well. touchscreen doesn't work nor does the home button. Volume down button seems to fail while in CWM recovery as well. I was thinking about replacing the digitizer but now I'm not so sure. Any help or advise would be greatly appreciated
If OP's saying what's busted is the part where all the digitizer, physical buttons, and LCD converge, that's the SLIDER FLEX. I replaced mine twice already. It gets pinched very easily. That's the weakness of slider phones. You have to accept that from the moment you decided to buy the Xperia PLAY. It happens to all sliders, live with it, face it.

[Q] Replacement Digitizer problem

Hi guys, i have a HTC Desire (GSM, SLCD) and a few weeks ago my glass panel broke. I bought a new one, and followed a guide to install it, and now my screen doesn't work. (The LCD isnt working.) Touch works fine though. i can enter my pattern, but i can't see anything at all. Replacing the old digitizer doesn't fix the problem.
Really odd, because i was really careful whilst replacing the part, and the display worked fine this morning.
This is probably a hardware problem, but i figured i post it here, maybe someone here had the same problem.
If the display was working before it must be something that you did wrong during the install of digitizer.
