There may, or may not be some information about the display take-apart
in one of the iFixit.com pages about the Apple Display Repair, here:

However having just looked -- note invisible pause in above space, while I did that.
The results are not so promising for some Display information. These don't show
evidence of take-apart; of course I was looking at Aluminum 20-23-30 Cinema HD.
Of this series, mine is the smallest. And I'm only into it for $60 including box.
Here's a copy of a pdf manual for a 22-inch Cinema DVI display; not sure if inside
is anything like the 30-inch, since they probably don't share many parts.

So there may be something about a 30-inch Apple Cinema Display, in hiding...😝
