I have a 2010 27" Cinema Display (with 3 USB ports on the back) which was connected to a Mac Pro. The screen itself does not display anything. I've changed the power lead to rule out any fuse problems TC, but nothing, so its not the lead. I've tried a different monitor on the computer and it works fine, so its definitely the screen itself, not the computer. No AppleCare on the monitor, but I do have AppleCare on the Mac Pro is was connected to, although I don't think this covers the display? I'm not sure whether the screen is just getting no power, or whether its the actual panel itself, as there is no power indicator on the screen? Anyone come across this before, or know what the possible issue could be? I'm guessing its not going to be a cheap fix?!!
