[HELP] Black screen on new phone screen - Xperia Z Q&A, Help & Troubleshooting

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.

[Q] Need help after replacing my amoled screen

So my Screen broke and I bought a new one so I could replace it, the touch screen/digitizer didn't break though... at first the colors just started washing and fading untill the screen ended up completely dark, I could still use the touch screen and feel when I would unlock it, after a day the phone would not give me any feed back by vibrating or turning the orange light while charging, so I dismantled it using some tips from these videos:

After I put everything back together the phone is giving me feedback again and I can notice its charging because of the orange light, but the screen won't turn on. Does any one know if I might need to do something on the software side? like needing to re install anything? or do you think I just got a bad screen?
Update: I just took it apart again and reconnected the ribbons, its back together and the screen still won't turn on.
You have the AMOLED screen and not the LCD?
Did you compare the #'s on the old and new to see you got the right part?
Cables are the same, they look the same, part # and stickers are different...
What are the part numbers on your new and old screen? I just went through the same thing, but I'm fairly sure I got the wrong screen replacement. Will have to look more into it later tonight.
My screen wont turn on at all. I was so excited to get my N1 back in action as well.

broken screen + black display

ok so my phone's screen is so cracked it fell off the second floor with no case to protect and the screen is broken like hell and the display is black (no display). However, I can see the soft keys still light and the phone still functions as I tried tapping over the screen and music played and camera captured so I guess every thing is working fine
So my question is if I buy a new screen and replaced it (from Ebay) will it also fix the black display and get my original display back ?
Hi, good day
do you still have your sensation xl? The broken screen one?

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