I got home tonight, plugged my Macbook Pro (2012 Retina) into the 27'' Cinema display and immediate saw that the monitor had NO power. Completely dead. No pass through of the USB or sound. Not even a charging light on the magnetic power connection to the MacBook.
I've been reading online, and it appears this is a power supply issue. The monitor's been making buzzing noises for a while that I believe comes from a not uncommon capacitor failure internally. So.. it's two years old, originally a certified refurb from Apple. No Apple Care or warranty.
I really like this monitor, but they cost a fortune (even as refurbs) and apparently don't have the best track record of longevity. So...
Next?
Apple for repair?
Independent shop for repair?
A different monitor?
Suggestions would be appreciated. |

If you're even somewhat handy and sure it's the power supply, you can buy a replacement part HERE for $138. You'll also need suction cups and a Torx screwdriver from Home Depot (figure another $20), then follow THESE instructions.
Otherwise, if you don't need the Thunderbolt feature you can buy a 3rd party IPS display for about $300.
(Edit to add better instructions)

I had a 7 year old LG lcd go bad and it was the capacitors that failed. Let me state I have a background in electronics and computer hardware so it does not scare me to take apart a broken component and replace the actual defective capacitor. I did a google search found a diagram of the three capacitors that was the most common factor. Opened the monitor found the topes of all three to be swollen. This indicates they are bad even though you can have bad ones without the swelling. I un-soldered the capacitors found an old piece of electronics and was able to salvage the parts I needed. Just match up the numbers and then repeat the process on the monitor that you are wanting to fix. You can find a step by step video on Youtube. You will need a few things. Electronic solder, wick, flux, and a decent soldering iron pen style. All in all the parts and tools should run less than 40 dollars. The experience will be priceless.

Diagram of the power supply board The round topped components are capacitors. These are what typically go bad when on dies. These are less than a dollar a piece on the high end. pennies if you have a contractor account and buy in bulk. Two leads to un-solder on each. I would replace all of them. and save a ton of money.
BTW Monitor break down instructions

| Just putting this out there in case you're still pondering. Bear in mind that the resolution is lower than a Cinema display even though both are 27". You'd probably need an adapter, too. |

| Turns out the whole power supply is dead. And... i bought it jus under 2 years ago on a credit card that doubles the warranty. That said, along with my general fear lack of tools and time... i've taken it into Apple and will get it covered by AmEx. |
