Black screen but can see icons with torch
Hi. I seem to be spending hours trying to search for the answer to this, but I'm going around in circles. I hope you can help.
I have an a1419 27 inch late 2012 (I think)
The screen is black, but I can see the icons with a torch. I can link my thunderbolt or external screen to get an image, this is fine. I tried replacement panel, no good. Now I am trying a new display cable, but the costs of trial and error are mounting.
What could be wrong? I am grounded when working on it. If it's the backlight what do I do on this model, as I can see they are all "slightly" different inside. I've read about fuses, and controllers, but not much info about the a1419 out there I'm stuck....
Thanks for helping
Is this a good question?

It really does sound like a backlight problem, in which case is out of my league.
The only other thing I can think of is if, somehow, the brightness settings were set to minimum (but I really don't think they even can go that low on the iMacs). To avoid possible unnecessary part replacement and hazzle, you should make sure by using the torch to help you navigate to System Preferences and then click Displays and make sure the brightness slider is to the far right. Also there may be a checkbox there that says "Automatically Adjust Brightness" that I'd leave unchecked in this case. I know this seems an unlikely cause since an external monitor displays a clear image, but one can never be too thorough. :)
