[Q] Replacement Digitizer problem - Desire Q&A, Help & Troubleshooting

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.

Separating Digitizer & Display

Hi,
My problem: Two months ago, the display of my Alpine (HTC 2020i) crashed (not the digitzer). I bought a new display from china for 80$.
This worked for about 2 weeks, then, suddenly the background-light did not work any more. While trying to reopen the device (for checking the connectors) the digitizer broke and the phone is almost unuseable.
My idea would be to separate the digitizer (which should work) from my old display and replace the broken digitizer with the old one.
Will this work? How to separate the two things? Is it possible without breaking it?
Another solution would be: http://cgi.ebay.at/ws/eBayISAPI.dll?ViewItem&item=330134835906
But there I've the same problem: How to change the digitizer?
Any hints are much appreciated!
Thank you in advance!
Best regards,

digitizer and display
it will work only if u will manage to put the digitizer correctly without distrubing the gas pattern on it recently my digitizer stop working so i sreviced it from a repairing center but i m not setisfied at all as i have to re align the screen twice or more in a day. so be careful while changing the digitzer do not press it too hard and check the youtube for the videos for how to change the digitizer they help u.
It is easy to replace the digitizer than the display.In this case one would have to b accurate to pull out the digitizer.There are 98% chance that it will fail, when remove digitizer from a broken display.My experience of fixing 100s of digitizers in various phones..including Palm and Athena

Wrong Digitizer?

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.

need help - touchscreen fix

noticed that my touchscreen is becoming unresponsive lately so i thought that changing the multitouch might solve it. the thing is, after selecting 4 touch, touchscreen becomes totally unresponsive. i tried wipe and even flashing stock os but touchscreen is still the same.
did i screw up my touch screen? how will i know? any known repairs or fix.
thanks
Sounds like your digitalizer (the glass above the screen) is busted and needs replacement. If your phone is under warranty, claim it, if not - get a new digitalizer and if you can't change it yourself, take it to a repair shop.
Changed the digitizer but still no response
Got a headache? It's all in your head!!!
switch ROM
You said that you flashed back to stock, but how about flashing to another ROM, I mean one that has a completly diferent multitouch enabler... that might work.

i was able to flash stock and it means i have no root nor recovery. and adb debugging is not enabled. i am out of ideas how i will be able to solve this.
After flashing stock ROM do you face the same issue with a new Digitizer?
yes. doesnt respond to anything except volume and power. even the 4 touch buttons doesn't work. i was thinking that i have received a bad digitizer or it is a motherboard issue. with the latter i have no idea how to check

I had recently taken my Defy to a service center. I just wanted to change the earpiece and the side casing. While replacing the side casing (while removing the Digitizer) they damaged the digitizer. The main touch portion was working but the 4 soft keys were not. They replaced the digitizer and everything was fine again (had to pay for it )
If you can carefully handle the phone, you can open up the casing and try reconnecting the digitizer to the board. (Do not remove the digitizer from the casing only reconnect the cable).
Replacement is better done by a service center as it requires careful handing.
I did open the phone, removed and reconnected the cable, still the same. also tried 2 new digitizer still the same result. I guess it us the mother board . Any ideas where to get replacement board ?
Thanks

i have got the same problem like you and i have solved it.
Do compass calibration like spin the phone 3 times in flat condition (laying down face up), then have the phone standing up and rotate 3 times, then on one side, rotate 3 times and then move your defy in the shape of number "8" in the air. Re-open the screen. it is suppose to bring back your screen work like it was nothing happened.
only for my defy i've tried never did this for another but from what i see you have nothing to lose here
Tried the calibrating thing and also a new digitizer. doesn't work. So it is the motherboard.
Anyone knows where to get mother board
Got a headache? It's all in your head!!!
Getting a new board is like getting a new phone - new IMEI, price for the board should be very similar to the pricw for a new phone too. If you think about it, it IS the phone. What's there in the phone other than the board a screen and a digitizer...
Guess you're right.

LCD Digitiser Replacement Issues HTC One X

Hi,
I have this HTC one x which needed a digitiser replacement as no touch would register. LCD was ok but decided to get a new lcd+ digitiser. I have replaced the screen and the LCD is working fine but the digitiser is still not working. iv checked the cables none are broken and the connector for the digitiser on the booard looks ok too.
Any ideas what im doing wrong or is it a board problem? everything else works fine its just the digitiser

Guessing you have tried factory reset / re flashed the correct boot.img?
trying that now but im on win 8.1 in bootloader i have drivers installed bt no access to fastboot or adb. but when i boot into os i have adb and im pushing rom.zip as PJ46IMG.zip and see if that works
right got it working but seems i have to put presssure on screen above the digi connector when i let go it stops again
iv jus realised that i put pressure on the top right of the screen to get digitiser working but connecter is on left side so now im stumped not sure whats wrong with it
any ideas anyone?
It could be you got a digitizer that has issues. I got one myself once, had to put pressure on top left hand corner to get bottom left hand side to register. In the end I sent it back for a replacement, and the replacement worked fine. If you go through the other steps posted above and check all the flex cables/connectors out and you still have problems, my money is on a faulty digitizer - it does happen occasionally.
