I would take it apart and follow the ifix it tutorial to make sure you have everything connected correctly.
thank you but I disassembled mounting three times its original flex. it is strange that with the new flex power LED was flashing the camera but still no power on the display.
If you have any ideas, thanks!
How did you fix? I have the same problem.
Hello!
I have a LG Optimus Black , and the touch function of the screen is not working anymore but the display shows a normally image at startup and I don't know what can I do except flashing it's firmware.
Can you give me some options to repair the device? The screen isn't broken, when I taked up from the computer's table, doesn't react anymore ( and I found the battery discharged )
Thank you!
Even after a reboot(battery pull) it doesn't respond?
You should take it to a service center.

Maybe there is a problem with the ribbon cable connecting the digitizer to the mainboard. I once saw this on my former Galaxy Ace. Since this is very tiny I would also advise you to take it to repair center - I broke my Ace when I tried to fix it myself...
I had had this problem too and I took my phone to service center,
they replaced the screen.
It appeared on my phone without reason , it's really a strange problem.
Hellooo:
First of all sorry for my english.
I have a problem with my new Optimus Black. When I make a call sometimes the screen gets black and sometimes it gets black when I put it in my ear (in this case the functionallity is normal). In the first situation I can't get screen on again. I think that is a proximity sensor problem but maybe a software problem. Maybe it needs a recalibration. I search for calibration tools but not luck. What can I do?
Thanks in advance.
Hi, my screen broke recently and i can't use the tactil touch. I can see the image but can't use. So i decided to buy a LCD + Tactil Touch + Frame. I didn't mount yet the screen. I only disconneted the screen flex and connected the flex of the new screen. But the problem is that is black. The screen seems to turn on but i don't see anything, is all black.
EDIT: I don't know where to ask. I flashed to the stock ROM, 4.2.2 and still black. I updated to the last version Sony has for my phone, 5.1.1 and still is black. I don't know what more to do. Is all working good, even the sounds when i touch the screen. But i can't see anything the screen is working but there's no image. My phone is Xperia Z.
Anyone?
Please help!
Broken screen? Is the old one still working? If yes: return the new and broken display and get a replacement!
The touch("screen") and feedback (vibrate and sound) will work without the lcd! It is a different layer on the screen and is seperatly connected to the mainboard of the cellphone. Also your screen could be working and your backlight not! Turn on the phone and point a bright flashlight on the screen, maybe you will see something, but even then, get a replacement.
Hello,
my Redmi 4x display stopped working after I had it in my back pocket whilst riding my bike. Display did still work but I couldn't use it anymore. Now I changed the display unit but the problem is still there, display lights up and shows me my background but then I can't use it. Also when I go to recovery mode I cant select anything and there is chinese and a lot of times the word fail.
Uploaded a picture of it here: ibb.co/fHTVPW9
Thanks in advance for any help.
Greetings

Did you test new replacement display before installing it, if it is working properly? it could be faulty display or maybe loose connection of digitizer flex cable.
