I also have a cinema display (20") with a broken hinge. The metal hinge is okay, but this morning I heard a creaking sound, and all of a sudden the acrylic casing around the metal screws of the hinge cracked in half horizontally. The display is almost never moved or adjusted, so--hello, Apple, are you listening?--this is obviously a major design flaw.
Since both halves of the casing are now cracked--that is, the half that came away with the acrylic leg and the half that's attached to the display itself--it looks like I'll need to find a whole new leg, remove the useless casing that's still attached to the display, and reinstall the leg, or find someone to do it.
Anyone with mechanical ability know if and how this can be done, and where you get the part? Thanks for any suggestions!
I thought of trying to use Epoxy to glue it back on, but that sounds so lame it's almost worthy of the genius who designed this piece of crap in the first place.
