Thank you so much to the gentlemen working at the Maccentric service center in Chatswood!
This morning started out as though it was going to be "one of those" Mondays. A blackout over the weekend had taken out my beautiful 23" Cinema Display after having just received a notice from the power company that the rates were going up by more than 10%! Talk about adding insult to injury, but fortunately I'm here working in dual-monitor mode now and I've never appreciated it more.
Everything else in the house was fine when the power came back on, but the power/status LED on the Cinema Display was flashing in a peculiar way and not working. A bit of Googling lead to an Apple knowledge base page which revealed that the sequence of flashes indicated a problem with the power adaptor. So I made some calls to the local Apple stores asking after a replacement.
The closest store informed me that according to their technician it can be swapped out with a generic unit available from any electronics retailer. Made a mental note not to visit their "genius bar" and called the bigger store in the city where I was advised that a replacement part can in fact be ordered by making an appointment with the genius bar. I decided to skip that and went back to the Next Byte store I'd originally bought it from.
They referred me to the Maccentric service center which was just around the corner. Turns out they actually had a replacement unit in stock! I bought it, took it home, plugged it in and - got the same flashing status light. Shit, at this point I'm worried that my worst fears have been confirmed and the monitor itself has been damaged. I had to call them back anyway to give the serial no. of the monitor, and when I did the guy suggested that I bring it back in to try it with the PSU from a 30" Cinema Display because he had seen that fix the problem before.
Not an hour later I had dusted it off, packed it up, and driven it back into the store. Unbelievably, they also had a 30" PSU in stock as well, so we unpacked it, plugged it all into a Mac Pro on a test bench, and my beloved Cinema Display sprang back to life! I just had to pay the difference between the 2 PSU models and the problem was solved!
So I highly recommend Maccentric for any Mac repairs you might need, the staff were knowledgeable and professional, and by recommending a $140 power adaptor they saved me from having to replace a very expensive and beloved monitor.
Thank you again to the Maccentric service center, Spring St. Chatswood!
(And a big F-U to Energy Australia for blowing it up in the first place!)
