Internal LCD Not Working
I have this 2013 27" i5 iMac that won't display any thing on the internal display. When it boots up the display just stays black no flickering or anything. I was able to get display mirroring turned on and it works fine with an external display as in I can use the external display instead of the internal one. I have checked the display itself and cables by swapping them onto another iMac that I have and they work just fine, however when they are in this iMac it doesn't work. All four of the status LEDS on the motherboard are green, and everything else seems fine. When I power up the iMac with the display disconnected the fan roars the whole time so I know it is detecting something.
Any ideas?? Thanks!

Have you changed the hard drive?

have you use a flash light to check if your back light is gone?

What @alexhus is saying is to shine a flashlight on the internal display at an angle and see if you can discern the desktop.

@mayer yes sir you are correct

I have tried that and it makes no difference at all. I can't see anything it's just not getting any signal.
