Well, I had problems with my 23" HD cinema display a few weeks back. I took it to the genius bar in cincinnati and they told me it was the power adapter. Go figure. It has been fine ever since. However, it has started acting up on me again. Just the other day, it has randomly been cutting off. I have to unplug the monitor from the power brick and plug it back in for it to respond. 1. Is my brick dead again? It is only 2 weeks old 2. Or is it something more serious? Thanks for your suggestions guys.
