Hi,
I've had this problem with my Cinema Display 42" and 13-inch, Mid 2009 science the cinema display came out. Happens about twice a day and looks exactly the same as this problem. Don't try an blame this on the 'New' macbook pros or 'thunderbolt' because its simply been a problem for years, and really calling this a problem seems a bit of an overstatement, it's not a big deal

Maybe you should take your Cinema Display 42" back to where you bought it since Apple don't make one. Someone obviously conned you
