yeah, if you connect the flex very well but the screen didn't work, you should do replacement.

X1's LCD got BLACK!

Hey dear friends
2 days ago my phone failed to the ground from top my bed and got wrecked
My phone's LCD show nothing except that a black screen with a little light
I think and I hope it's from that cable that connect contacts of LCD to main board I think it called Flat or something else.....
I disassemble it my self and I wanna to show it to a mobile service center tomorrow....
anybody have any idea about this issue?what's the problem?
Before you start considering taking it apart, try plugging into your computer first.
I know it sounds daft, but after I dropped my phone last summer, when I tried to turn it on you could see a slight change in the shade of black, yet nothing would show. (Implying that the screen was still powered in some way, but just didn't display anything)
I'd just tried to plug it in to get the data off it before sending it away after a few days of hoping it would come back on, and the screen came back on!
It might not work for you, but it's worth a shot!
Last Xperia X1 I had for repairs had black LCD after a fall. It buzzed and started up, but LCD remained black - flex needs to be replaced.

x8 black screen

Hello
i have problem. i have droped x8 from about 1m and when i get it in my hand the screen was black.
Probably the screen is broken. But before i orded new i have open my x8 and see that screen is not broken or something like that.
there are no color just black. and sometimes when i press it harder i get vertical green line.
is this the screen or the hardware on my phone.
I have check the mbo but its seems fine...
so give me your opinion

here you can see on 0:58 how the screen is broke in my case is not the same my is all black and when i turn on phone just litlebit light up and thats all.
in up left corner i have litlebit white and thets it
Sry on my bad english
It looks broken i think.... But how did you manage to broke your x8 i have dropped my many times even throwing it without anything happend
i dont know i was just put another karnel and rom.
and its just fall from my pocket becouse i have the hole -.-
and its just black screen. i have order new lcd from ebay. But i will kill myself if the mbo is dead -.-
IMO if You turn on Your phone and You can see green light and feel quick vibration than only the screen (or digitzer) is broken. So if You replace it with new one everything should be fine.
yeah its light up green the led and vibrates. but screen is dead. the digitizer is fine.

[Q] Dead?

Well back in February i smashed the screen on my vivd. Still wokred just a smashed screen, at that point i put it in the drawer and moved on. Well i just broke it out agian today and plugged it into my PC and now i only have backlight (no real screen) and the LED indicator is lit orange. My PC loaded the drivers fine, but ive never seen this. It worked after the drop (and used it a bit after as well) but never did the screen totally die.
Im assuming the phone is still alive, but do you think its anything more then a screen replacement? With the touch panel on the bottom im hesitant about replacing the screen myself, i think radioshack does screen fairly cheap. Thoughts?? Dead? Restorable?

i would think you would have to replace the lcd since it shows the image, might wanna replace the digitizer/screen while your at it too cx

Replaced screen, still black

Hi
A month ago my screen suddenly went completely dead, the phone it self was functioning normally except the screen, \
so i posted this thread : http://forum.xda-developers.com/xperia-z/help/how-to-make-screen-dead-t3175115
then i decided to tear down the phone, i did and i played abit with the lcd flex cable, i got the screen to work but with very low brightness and a lot of blinking, i played a bit more with the same cable
and tried powering up the phone, the screen gone completely black again so i thought i broke the cable
i ended up buying this
www.aliexpress.com/item/LCD-touch-s...ria-Z-L36h-C6603-LT36-display/1449119790.html
it arrived and i played a youtube video of the device dis-assembly and copied every step exactly, tried powering the phone up and the new screen is black!
anyone have an idea what's going on?

Maybe something not connected, or because it's aftermarket screen. There are lots of screens for sale but I don't believe they all work as good as the OEM screen.

Did you ask the seller to exchange the item? There is always a 10% chance of a black screen when buying a replacement screen.
If you tested the screen by just connecting it to the motherboard,and it didnt work,you should be able to get a replacement for free(but you will probably have to pay for the shipping when sending the broken one back)
By the way. I need to get a new screen replacement(the current one started flickering and glitching after 5 days of usage-I literally held the phone on the desk,answering calls and putting it back on the desk,so I couldnĀ“t have damaged it),but I cant waste money. Was the package in a good state?
If anyone can recommend a cheap,but working screen(I dont care much about the 10% weaker colors,I just dont want the screen to flicker and glitch out),I would be extremely grateful.

[HELP] Black screen on new phone screen

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.
