Any updates Apple? The last software update didn't help. The monitor is still black.

Have you solved this issue yet? I encoutered the same issue after my laptop was upgraded to Mountain Lion.
The cinema display used to work with my laptop with Lion OS

I have this EXACT SAME problem and have tried any number of power cycling combos. Read several other threads and it doesn't seem like there is any solve yet. C'mon Apple. Fix this.

I paid Apple a Single Support licens, and we figured out how to solve my issue. I will put the articles Apple took me through in the bottom of this post, I hope this will help you guys out aswell.
During the first article (Resetting the System Management Controller (SMC)), my monitor suddenly woke up and began working. I've been using my monitor without any problems for almost a week now.
I'm sorry I haven't shared these articles sooner, the supporter forgot to send them to me as we agreed, so I had to call Apple again - which I did today for the purpose of sharing.
I hope this will help at least one other person.

Totay, I took the cinema display to the Apple store at local. The guy there said that there is a problem with the monitor, and some component inside is broken, after he tested with several ways. But I donot believe him.

I checked the post online, and some guy suggested we should use the 150W Power Adapter to seek a luck. Does anyone want to make a comment on this? My display is 23' one and a 90W power adapter comes with it.

Same here. I've searching multiple threads and forums searching for an answer on this.
My 23" aluminum Cinema HD works fine on my iMac running Lion, or Macbook running Snow Leopard.
But, plug it into my brand new Macbook Pro 13" 2012 running Mountain Lion .... and nothing. Tried power resets smc and plugging in monitor first or while sleep or ... etc. Tried all the possible fixes all over the net. Nothing.

My problem is fixed - should have though of it at the start. I was using a third party Kanex iAdapt MDP -> DVI connector. Bought an Apple version and all works great so far.
