Hello
I received 27" iMac, Late 2015 model that's broken. I don't know what exactly happened but it appears to be unopened and there are no marks indicating prior repair attempts.
Initially it didn't display anything on the screen and backlight didn't work. Only 2 diagnostic LEDs would light up and 3rd was very faint. I opened it and found F4400 fuse near eDP connector to be blown. Replaced it with a suitable part and backlight came back to life. Unfortunately it still doesn't display anything on the screen. Now I get 4 green diagnostic LEDs.
Hello, I have an iMAc 27 inch late 2013 EMC 2639 at work that doesn't start, it has a prohibited symbol and/or when I connect the system via USB it stops on the apple.
Is this feature locked in the bios?
Thanks in advance
