I Cracked my screen to the point the bottom half no longer worked. I got a replacement and installed it. My LED light comes on and I can feel the vibration when 'unlocking' but my screen is black/blank. Does this mean I have a faulty LCD screen or do I need to do some type of hard reset?

My display seems to have cracked in an odd way. As you can see, there is a hairline crack, but I can't feel it with my thumb - either it hasn't breached the surface of the glass or its in a layer beneath it. The phone boots, but the screen is 100% off.
I get touchscreen response, as it vibrates when I roll my thumb over the unlock points. My trackball glows, and it looks like the phone is in perfect working order besides the crack and dark screen.
What do you think is going on? Does something need to be replaced or might something just be loose inside? Is there a way to determine that without opening it up?
Obviously, your LCD is gone.
Try to re-connect the LCD Panel on the motherboard, then try to light up the screen using a flash light, preferably a LED one, just to check weather the back light is damaged.

I had a similar thing on my old wildfire. You've got to get a new LCD screen.
I have a Galaxy Captivate from a friend who has dropped it and shattered the screen. The bottom 4 touch buttons light up when the phone is powered on, he claims that there was a very faint image on the screen but so far it hasn't displayed anything for me.
Is it likely that a touchscreen + digitizer can fix this, or is it likely that something else is wrong with the phone? The touch buttons lead me to believe that I may be able to replace the screen + digitizer and have it work again =/
Opinions?
Hello everyone,
I have got one problem... I broke digitizer of my HTC Desire 500. So I order new one and to be sure, also LCD screen. I replaced, and...
After turning on, everything works fine. Digitizer works properly, screen shows normal picture. But after few minutes - restarts (I don't remember well) backlight of my screen goes down and now it have no backlight at all. I rebooted phone many times, I remounted screen and digitizer to be sure that connections are fine - but no results. I restored factory settings of phone with no effect too. :/
Please help, what happend? What could be the source of problem? I don't want to order new sceen if it could beak too ;/ I read other threats about coil problem in other HTC, but I cannot find any coil in my Desire's motherboard (maybe it is hidden under plate that covers CPU and other parts). I performed tests of light sensor and it works fine. Buttons lights fine too. The problem refers only to LCD screen, and backlight doesn't respond during test.
Anyone help?
same situation
Hello kowal_luki,
I'm just in the same bad situation.
After a bad fall of the phone the screen broke so I ordered a new one for replacing it.
Opening the phone I noticed that also the LCD (and not only the external screen) was broke so had to order also the LCD.
As precaution tried to power-on my device without a complete assembly and everything seemed to be fine, so I decided to glue the LCD to the outer screen (the touch screen) with a LOCA TP-2500 glue.
Then I re-assembled it up: at first the image was a little bit disturbed but the back-light was working; after few second the back-light turned off. I checked the cable, after that the image went perfect but the back-light still dead.
Did you find a solution for this -still not explanable- problem?
Hello pros,
I have searched this entire forum but no answer, hoping you could help me.
My z1 had some water damage, to make a long story short, here are my issues.
1. Lcd was shot. It was all black Screen.
2. Although screen was all black, i could feel it vibrate and has audible sounds.
3. Touch screen still works. I am able to make and accept calls with or without my smartwatch.
4. With a very bright led flashlight shined upon the screen i am able to see whats on the screen.
5. Bought a new lcd+digitizer with frame and replaced the original one. Followed exact process as youtube vids.
6. Screen now lights up BUT touch screen does NOT work anymore.ggrrrr!
7. Bought another lcd+digitizer with frame thinking i got a faulty one. Same issues. Lcd lights up but no touch feature .
Questions:
1. Is it possible that the flex cable connected to lcd+digitizer is broken? If so, replacing the cable will definitely fix my touch screen issues?
2. Is it possible that it could be a hardware issue? If so, how do i fix it or replace a specific part?
Any and all response is highly appreciated . Thanks
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.
