Hello everyone.
I have a problem with my smartphone Sony Xperia Z2. I dropped it and the display broke. I bought a new display. When I connect he went crazy. He began to open the application, clicking like 10 fingers working on it simultaneously. Because I thought that the display is faulty, I've exchanged for a new one. But now even bigger problem. When I turn on him, he does not show anything on the screen except the backlight. Do you know what the problem is and whether anyone had a similar problem? So, when the smartphone turns on, lights up only the backlight but nothing on the screen showing a. At first, there is a lot of vertical lines on display, and once he just fade out, and from that moment display is blank only backlight working. I try to update software, but nothing change. Restarting, and turning off also nothing.
Please help me solve this, for me very frustrating problem.
anyone?

Did you ever get this resolved?
I had this issue after a screen replacement for a shattered screen. I was sure I had damaged something in the process (ribbon flex cable, motherboard, etc). Turns out the replacement screen was faulty. A new working screen solved the issue.

Hello everyone. My xperia neo fell down and the screen is broken, not the digitizer (i think)
I disambled the whole phone, and i have some doubts. When i only plug the display and turn on the phone, the screen turn on, i can see the screen light. But when i plug the digitizer and the buttons and turn on the phone, the screen doesnt turn on , no light.
Its this a display problem? if i buy a new one it will works? or all the phone is broken?

Cant repair?
Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
Hi,
Trying to fix a Z2 for a friend. She dropped it, smashed the screen. You could still see the LCD, but the digitizer was fubar. Ordered a new screen assembly, but after the replacement only the LED backlights work - no LCD at all. To test, I reinstalled what was left of the old screen, and no LCD, just backlight, so I don't think it's the new screen. So then I ordered a new main ribbon cable and replaced it. Same result: no LCD, just backlight. You can hear the phone on when it's on, the phone "responds" when you touch the screen, you just can't see anything. I upgraded to the latest software update tonight using PC Companion, but no change.
So, the only thing left is the motherboard, right? I know there is a fuse on the motherboard that, when it fails, it kills the backlight and leaves you with only the LCD. I have the opposite problem. I'm hoping maybe there is something like that for the LCD??
Thanks in advance,
Heath
I have same issues with you and also try ten new lcd all show backlight only..what your solution??
Have you tried to connect it via a MHL cable to TV ?
I have Xperia z3. When I turning on phone Lcd light on but screen blank. I can heat sound and so on. Digitizer when pressing is working as I hear nose. But screen still blank. | tried few screens but still same. What it can be????
Please help.....
This is the Z3v forum not the Z3 forum.
I would say a screen failure though.
Verizon has open enrollment right now so you can enroll in a insurance plan and get another phone, if yours is out of warranty.
Your Display is dead - Had the same problem.
Everything worked fine just my screen wouldn't show me anything. Ultimately I replaced the display by myself because I didn't have any warranty and now it's working again.
You could try to send it back to your vendor or order a new screen (70-100€) from ebay and replace it yourself.
Good luck!
Hello,
I guess I have the same problem:
I got a Z3 one year ago.
But spontaneously the screen just stayed black.
I can boot the phone, the backlight is working. I wait a little bit but the screen is still black.
BUT I can touch and select camera and take a photo. I know, because I can hear the sound of camera. I can open the dial pad and dial a number, I can hear the different sounds.
The phone is original, have never been opened, no other software.
I already tried with "Xperia Companion" to install latest updates and repair the phone. Nothing worked.

Did a screen replacement solved your problem?
A feedback how the problem was solved would be great because I don't wanna buy an expensive screen if anything else is broken in phone.
Hello!
My phone fell from a high place some weeks ago and the screen shattered. Touch was unresponsive, clicking everywehere, but LCD was fine, i could see everything on screen normally.
Ordered a new screen. Changed it, but when I turned it on, only backlight of the LCD was visible, but it was displaying nothing. I thought it was a defective screen (either way, it was, lots of stuck pixels), sent it back and bought another from the same seller. When I changed it and turned it on, again, no video output, lcd would light on but woundn't display nothing on screen. Googled a bit, found out it could be a defective fuse on the motherboard, and that soldering it again would solve. I know nothing about this kind of stuff, so I picked up a tweezers and apllied a little force on every fuse, because I thougth that way I could try to solve it. Well, it worked, kinda. I put the screen above that blue plastic glue only for testing, and it worked, I felt reliefed for seeing sony boot logo again. Figuring out it had worked, i took out the screen, took out the blue plastic, and glued the screen back on. For my surprise, it had the same problem as before, and it doesn't matter what I do now, it wont work anymore, only displays a black backlight with no video.
Could anyone help me out with this? Give me a hint of why it worked once but not anymore. Could it be there's really a defective fuse, or it was just a coincidence that it worked after it had force apllied? Also, the Screen flex is kinda loose, it keeps coming off all the time, and it's really hard to plug it to the LCD sometimes, is it supposed to be like that, or could it be the culprit? Also, touch is working normally, i can't see nothing on screen but i can click and feel it vibrating.
It's kind of a big text, but that's the way I could explain it. Sorry for the bad english, it's not my native language.
And thanks in advance if anyone can help!
