Hello I noticed your comment, I have a Jan 2003 A1038 M8893ZMA Cinema Display I found at Tohoku University dumped outside in the rain I took it home but it fell on the ground and cracked I do not know if I damaged the inners but I took the back off and glued the cracked part and let it dry I do not know how long it was in the rain but it did not seem water got into the inners.
Anyway put it back together and I have a Mac cube and 2 old G3 s but I think the specs are not sitable with them. Then I got a second hand Power Mac G5 2005 it has 2 kinds of sockets at the back 1 fits the Apple cinema display.
I connected the keyboard and mouse to the display not to the power mac and a light for seeing ;the power comes on and I can use the Power button to turn the power on an off and it is just shining no picture like it is on sleep the mouse and keyboard lights show bI know the Power Mac works because I installed 10.4 via firewire from an ibook.
The previous owner seems to have put a graphics card above for HD DVI monitor would that prevent the original working? I guess he did not use an apple display there is no Manual for the display only specs but the machine and family number do not match.
I know what it it was thrown out but not because of it being broken but they just want to have latest version.
