My Thunderbolt display has developed a problem in which a sound comes from the left side when the monitor is at a brightness level greater than 40%.  The sound is like that of a fly's wings stuck in something but it only occurs when the following are present:  1) monitor plugged in, 2) monitor connected to laptop, 3) the brightness is greater than 40% of the total amount in settings.


Has anyone had this problem and if so, what was the fix?

Thunderbolt Display (27-inch), Mac OS X (10.7.5)
