My 30" cinema display has stopped powering up, am I right in presuming this is a 100% a hardware problem? It literally stopped working.
I have the same problem. It started no powering up intermitantly. I'd plugin and get nothing, then I'd plugin an hour later and it would work.
I tried replacing the display-port > Dual DVI cable and the issue still happened.
Now the monitor wont start up at all. Not fun!
