Hi,
I have an 2017 imac 21 with a black screen. Have tried to troubleshoot it with the logic board LEDs and I have 3 solid green ON but the one for display is Off. what troubleshooting steps I should take to find out if the issue is the display? I have connected it to an external display, but that is not working either.
