2010 iMac black screen mystery

crwdns2934249:0crwdne2934249:0:

I have a pretty mysterious case with my 2010 imac 27 inch.  The screen suddenly went black.  The computer boots up fine and runs with an external monitor.  When I shine a light into the lcd display i can see the image that should be on the screen: so the panel is recieving the image but the backlight isnt working.  I replaced the led inverter board, but nothing changed.  So i replaced the whole lcd panel, and no change.

I did reuse the displayport cable from the old panel, so I suppose that could be faulty.  The thermal sensor seems fine because if I unplug it the fans go crazy.

What else could I be missing?  I'm worried I've reached the end of my technical abilities and am really stumped.
