So I just replaced the lcd and digitizer in my OGP. My touch screen doesn't work on the new digitizer. The old touch controller chip was made by WinPower. The new touch controller is made by Synaptics, much better company. My question is this. Do you guys think its just defective, or should I do a factory restore to see if it works? I'm just not sure if maybe a reset will reflash the touch firmware also.
It's say by repairuniverse.com to do a factory rest after the installation. Make sense since you just install a new hardware, and the device needs be reset to accomodate the new hardware. Synaptic chip seems to be in all the replacement digitizer these days. We can no longer buy the real oem digitizer, only the oem quality ones. Please let me know if factory reset does the job for you, for I'm waiting to replace my broken digitizer glass as well.
Edit: my digitizer repair was a success. It was working fine with the factory rest. But I did one anyway just to recalibrate the touch screen. It makes sense, doesn't it? Be sure to check the digitizer connection, and make sure it is connected real well.

Hi, I just bought a replacement digitizer from ebay, I first have to say that this will be my first replacement, so maybe I missed a step. So after I replaced screen, I connected the 3 connectors like they should, I screwed the one screw on the top right, and screwed the 6 t-4 screw. I turned on the phone, and it seems like it wont register touch. It also seems that its more responsive to touch when plugged to the wall. I was able to get to the calibrate touch screen, I was finished with that and still no response. So now my question is...
A) Did i miss a step?
B) Is this something common and can be fixed with settings?
C) Does this sound like a bad digitizer?
I emailed the company that sold me this digitizer, and they will exchange my digitizer. But before I ship it back I would like to know if it was me who is doing something wrong, or if its the digitizer.
ps. Not sure if I can post the link to the ebay item...
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.

I have broken screen on my htc desire hd, i have replaced the LCD+digitizer before. i know my way around this phone.
Is it easy to replace just glass screen ?
I cant see how i can seprate them. they are glued in this black glue thingy.
Better buy whole LCD + digitizer?

I need to do the same. Also since dropping the phone my Bluetooth turns on and off but doesn't always connect. (highlights or ticks option , but I'm not getting anything on the top bar). I disconnect and re-connect a few times to get it working
While I have the phone apart is there anything I can do to fix it?

I just replaced the glass only on mine. Unfortunately, the touch screen isn't responding. Anyone know where I might have gone wrong??? Everything else seems to work fine!
Probably a Ribbon Cable.

Try taking it back apart and re-place the ribbon cables back in there seat, they may not be making proper contact. If you replaced the glass without taking it apart you probably un-seated one of the cables. When working on iPhones there is a cable that is only held in place once you close it and put the phone back together.... It's a PITA.
Buy new part and dont replace . Your self its difficult. And its not easy
You can buy a "used" DHD device to replace yours. It'll be cheaper and easier... With a backup on sdcard, your device will be the same !
Hi!
If you want a bit of background, you can read my previous thread (the third post).
Long story short: I have replaced my screen with a LCD + digitizer assembly, and I have no touch function. It is completely unresponsive, even in recovery, so I guess it is a hardware issue. Here are my questions:
- What else than a flaw in the assembly can it be? Some connector? A separate processing module for touch?
- Does the digitizer have to be glued to the LCD to work? I happen to have a spare digitizer-only, so I thought maybe I could disconnect the digitizer glued to the screen (but not remove it), and connect the spare one I have and test to see if there is some reaction, but given the short cable, it would just be dangling. This is just for test, though, but if you tell me it has to be against the LCD to work, then there's no point...
Cheers!

I replaced my screen three times (LOL), i had the same issue, ask your seller for a replace, it is a HW issue for sure.
By the way, if you can't ask for a replace try to connect the digitizer and see if it works, but for my experience, unglue the digitizer and then replace it with the one you have is a "fool" thing, you can't do it with your hairdryer, you need a specific HW
Hi guys
I wanted to ressurect my old moto g5 (cedric xt1676) which i was not using for a longer time. Screen was cracked but touch worked just fine. I bought screen replacement assembly and connected it. Screen (picture) is working fine but touch is not working at all. Is there any way to solve this problem? What i found untill now is that after some update motorola/lenovo disabled support for 3rd party screens - one i bought is stated to be "original" but i doubt it.
I did a factory reset before removing old screen, after connecting new one, start menu was in russian (i can't read bukvas so its a guess ), after another reset it is back to english but touch is still not working. There is a padlock symbol in top left corner of the screen.
I just wanted to fix the old phone to give it to the family member but now i spent so much time on this issue that i want to fix it very badly.
Hope that someone can and want to help me.
At the end of the day it's all down to if the correct parts were used and if it was fixed correctly. Nothing we can really help with here.
It's Russian ransomware screen
Seriously always use OEM parts.
Make sure all connectors are intact; remove and inspect contacts. Make sure you didn't miss a ground or data connection; sometimes they are just contact points between assemblies. Using the wrong length screw may cause a missing contact pathway. Assemble exactly the way it was.
The mobo may have been damaged when the display was broken. High G impacts can internally damage chipsets and crack solder joints. Flexing a multilayered mobo can break internal traces.
Sorry to hear that. Anyway - i have nothing to loose so i would try with olderversion of android - is it possible to instal without working touch in the phone?
