imac 27 late 2013 black screen until after several restarts

An update that may confuse more than help.Īfter reading through everything I could find on here and on the Apple support forums, I thought that I had better go through all the possible self help options again before taking the iMac to the Apple Store and finding that it wouldn't show the fault. Doesn't hurt to ask! If you still have an independent Apple-Authorized service shop somewhere close to you (there still are a few), then that's where I would try first. Some folks here seem to get the idea that Apple service is always tight-fisted, but there are (perhaps anecdotal) stories about getting free repairs. Those are likely failures, and you should end up spending 3 - 400 dollars, maybe less.Īnd, the video card is replaceable, too, and will be higher, depending on which one you have.Īnd, there's the possibility that the screen is failing, which will be considerably more.Īnd, it may be worth your time to talk to a 'genius', as there are occasional service programs, that can provide repairs, if you ask for them.

Neither of those two parts are terribly expensive, and not too difficult to replace. In that case, there's a backlight board that may be failing. You can tell because you will still have visible screen elements (Menubar, Dock, windows, etc) if you look carefully, perhaps by shining a bright light into the screen.

Did you determine if it's really the screen? or is it simply the backlight?
