My 20" Cinema Display won't power up. The power light blinks "short-long-short". Apple Tech post says this indicates faulty power supply. I tried another known working power supply and still got the same error. It is plugged into a MacPro 2.66 dual core Xeon machine with a 23" monitor that works fine.

 

Any ideas?
