After 2 and a half years, my 23" Cinema Display just stopped working. All USB ports, firewire ports and the monitor itself. Now, I try to connect it to my MacBook Pro again and I notice the light on the screen goes on for 1 second and then shuts off. Still nothing displaying. I'm assuming its some hardware problem and that the display is giving up. I find it frustrating that paying around 1000$ for a screen like this just gives up in this short time. Is there any one else that this happened to? How much is a hardware repair on these screens? Do you think theres a way to make Apple give a discount on a new one or something?
