So like the title says, my 27" Cinema Display is dead, kind of. So the video is out, but the usb audio and charger still work fine. Also, when it's plugged in, my laptop still recognizes the display. I did some research and found some people have said it's an issue with the logic board or the lcd panel. Has anyone else had this issue? If so, was it something that could be fixed or should I just buy a new one?
