Title:

Blank screen and external monitor

Text:

I work on an external monitor via the DisplayPort / Thunderbolt connector with the MBP closed most of the time.
 
Yesterday the monitor went blank whilst I was working.
 
I lifted the MBP lid expecting to see the Retina display still working but that was black too.
 
I also note that the Apple logo is not lit any more.
 
The MBP chimes and boots correctly to the point where I can log on to it remotely using screen sharing.
 
iI have tried the two key combinations on boot that reset the firmware but that made no difference.

I’m unable to find any report on the web from anyone who has had both retina and external displays not workingworking, although I will continue my search.

AnyIn the meantime, any ideas on which components may have failed and how to confirm that would be massively appreciated.
