Black Screen with Sound
I used to have my Mac Mini (2009 edition) connected to my living room tv. Since we recently upgraded the surround sound, I was wanting to connect it back to my 24" cinema display in the office, but when I connected everything and powered on, I'm not getting any picture. Just a black screen. I've done minor troubleshooting using my Mini and my Air. The mini still connects fine via mini display port to my tv, and my air will transfer sound to the cinema display via the usb. Is there a way to determine if the display port connection on the all-in-one cable to the cinema display is bad? Or at this point am I forced into trial and error with swapping out parts? Please let me know if you have any ideas. Trying not to buy a new display in new parts. >.<

For what it's worth I have a similar issue except that its a black screen with sound when I plug in a PC to the cinema display. The way I resolve it is by unplugging the monitor thunderbolt cable from the PC and plugging it into my macbook pro for a brief second. Once the mac registers with the cinema display I can plug it back into the PC and the PC connects just fine. Super odd but works every time.
I have identical issue.. with Cinema Display going black for no reason from my iMac and it does turn back on and works fine connected to a MacBook and then works on iMac after as per your fix. But it does go black again shortly.. Any clue what is happening here? Would obviously like to find a permanent solution
