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 internal display disconnected using just the external display the fan roars the whole time so I know it is detecting something when the internal display is connected.
Any ideas?? Thanks!
