I have this same issue with my 27 680MX iMac after swapping drives. I ran the apple hardware test and nothing comes up. I also tried taking a screen shot but nothing shows on the screenshot. Its just one thick black line from top to bottom of the screen.  Anyone know if i might need a new display or a whole new motherboard?
