Upon reflection, I think my issue is different. Probably should not have posted it here. As it turns out sometimes my display works, sometimes it does not. I think the power adapter has gone bad. A common occurrence here in Mexico where the power can fluctuate quite a bit. - Ryan
There are couple of long threads in the display section about problems with the power supplies on the 23" HD DVI. See this one for instance: https://discussions.apple.com/thread/2086442?answerId=17981683022#17981683022
Mine one day just wouldn't turn on -- connected to an old G4 MDD and the Mini -- a bit of fiddling it would occasionally start up, sometimes not. Similar to what you described, the Macs would see it in System Profiler, but it just wouldn't turn on.
Based on that thread, I figured the problem was mostly likely the power supply. A local authorized repair place didn't have a spare for me to try, but the tech sniffed it and mentioned it the burnt electronics smell. LOL, I sniffed it and sniffed the power supply for my 20" DVI Cinema display -- indeed a weird smell.
Based on that thread, I decided to bite the bullet and buy a beefier 150" power supply for the 30" Cinema display, which Apple says in compatible with the 23". See: http://support.apple.com/kb/HT2803
I hooked it up, crossed my fingers, and it fired up right away. It's been working fine for about 3 months now. Cheaper than buying a new monitor.
