I don't have an answer, but instead have a similar problem. This page was very helpful but am uncertain how to interpret for the computer in front of me.
 
It's a 2009 MacBook Pro - I bought it with a busted screen, and since I had another display lying around I thought that would be a quick and easy thing to swap the displays. Unfortunately it wasn't to be that easy.
 
This computer displays perfectly on an external display. It recognizes there is a second display (the laptop screen) and I can drag windows over to that screen, and it behaves like it's dragging the window to another display, etc. In other words, this laptop believes it has a functioning laptop screen but nothing is shown.
 
I tried booting with the display cord disconnected. While booted that way it did not show the second display as a possibility. Then rebooting, and the problem did not magically fix itself.
 
I've resent SMC and PRAM. I've fiddled with the keyboard brightness keys. The keyboard backlight works fine.
 
I just tried shining a light on the screen and did not see any faint images. This was done with Display Mirroring on, so to have a known image on the screen. The blackness was uniform across the display.
 
I've tried swapping in two different displays, both of which "should" be working correctly, with no luck.
 
The Apple logo on the back is not lit up.
