I recently purchased a 2015 iMac already disassembled with a cracked screen. I purchased a replacement screen that came with the display power cable and temperature sensor. I did notice the display data cable below the FaceTime camera was empty. I also noticed the port on the motherboard was also empty. When testing out the screen without taping, I connected the display power cable and attempted to power up, Nothing! I just need to verify that this cable is required and is in fact the missing link. The screen is the LM270QQ1 (SD)(B1), EMC 2834.

Hi Ivan, I have iMac 27 “ 5K Late 2014 without LCD, when I installed the new LCD and the new LCD Flex Cable, it does not turn on, Black screen…but with external monitor iMac works perfectly… The two cables different for 2015 models cause the malfunction? THANKS
