24 LED Cinema - Something "peeling" away from behind the glass.
The LED does not appear to be distorted, but is obscured by whatever has just started to peel away from the inside of the glass. I double-checked this by moving windows with sharp edges over the area, and you can see the text, etc. peeking through on the other side of this thin strip, undistorted.
I have scheduled to take it in. But of course it’s out of warranty. Given that it’s only about 15 months old, I’m curious if anyone else has seen this. It's a first generation LED display, but hopefully this is just an isolated anomaly that can be easily repaired.
