No display, Working phone, screen intact

[Deqin]

Please advise if this is fixable

 I

Everything is still running, I still hear a ding when I receive a msg, but it's impossible to unlock the phone as the screen is blank.

It happened when I slighly dropped my phone, could it be the video chip shifted a little and simply needs to be adjusted back..

or is the plasma broken...

Thank you

I'm sorry to hear this, but no one will be able to answer that question, you need to get your phone inspected at your local Xperia Care

There are myriad possibilities on what could be the issue. On a side note, there aren't phones with plasma screens, the Z3 use a LCD screen.
