[Q] Touch screen not working after replacement, please help - Defy Q&A, Help & Troubleshooting

I have a moto defy which I replaced the touch screen (digitizer) from one that I purchased on eBay, I did it, but now it does not respond to almost any touch movement, I can't type well, I can't answer calls, etc, etc, so I went back to the old screen which was working fine and now it has the same problem, what should I do? is there any way to recalibrate the screen, assuming that's the problem? please help me out, thanks!!

Any help? No one?

[Q] Do I need a replacement screen?

The vibrate function on my HD2 has not been working from day dot so I decided to open it up and check the vibrator. I pushed the vibrator in tight and closed it all up again.
When I turned on the phone, the screen was displaying what looked like 256 colours. The screen is still responsive and everything else seems to work (except of course for the vibrator).
Question is: Have I broken the screen or is there a connection problem which would cause this?
Any ideas please?
Im not really sure. Was there anything you did that made it stop working?
ok - for anyone in the same situation. I have managed to put a 3mm split in the flexi cable between screen and motherboard.
Off to ebay to get a new one now.

[Q] Display/Digitalizer problem

Hi!
I lost my phone on the ground and it got a big crack across the screen. However, the screen is still on, the picture and colors and everthing is fine, except there is not reaction when I touch. I've tried resetting the phone but it doesn't work. There is not touch anywhere in the screen. So I'm wondering if the digitalizer is broken, or if the problem is elsewhere? Can I fix this? Would it work if I bough a new dispplay and digitalizer to replaced the old one?
Maybe the touch screen is not working? If you turn on the phone, do you get the animations correctly?
I get the animations correctly. Everyhing seems to be just fine, except i cant touch.

[Q] Replaced lcd digitizer not working

Hi
I have broken the screen of lenovo A3000.
I had replaced the touch screen but the touch screen is not working.
The broken touch screen works perfectly.
There is no loose connection. I tried again and again.
Is it because of driver problem or is it because the new touch screen is faulty?
The touch screen seller agreed to send me a new one. But until it arrives, I want to confirm source of problem.
Please help.
Thanks in advance

i recently replaced the lcd and also have the same issue. It detected that my screen is covered so i can't hang on a call because the screen wont turn on.
but suddenly it works when i cleanup the screen with a damp cloth. but sometimes it doesnt work.
I know this thread is super old, but before I start a new one on exactly this - I had to disassemble my phone to replace the audio jack, and since then, my proximity sensor won't work at all. I double checked the flex cable and plug, tested the sensor outside the phone, still nothing. It ONLY works if I put sth white or metal-like exactly 2 mm away from the screen, no nearer, no further. Its super strange and annoying. Was anybody able to solve this?
Edit: LED and ambient light sensor (which is exactly the same sensor) are working! And before the sensor stopped working I did not even touch it at all!
