Nokia Lumia 920 screen blackout

[Shafique Chougley]

My phone NL920 is having the issue, It is alive (inside) but the screen is completely black. I can feel phone getting lock/unlock. Phone rings & able to recieve call (guessing the touch location).
Tried soft restart (Power+vol down), it doesn't help.
It has same issue, earlier, nokia care fixed it. but refused to explain what has happened.
Now my phone is out of maintenance & expecting it to be the big hole in my pocket for repairing.

did it fall?? maybe the screen connector was taken off and doesn't give any signal...
