I finally exchanged the monitor (I was within 30 days on Amazon- by one day) and it has not happened since. I have worked, viewed videos and movies, and it has not blacked out yet. So if you are within your exchange timeframe I would send it back!

When I first purchased the display, it would not work then randomly detected and was fine for sometime. I used it within both osx and windows 7 via bootcamp without issue. I went away for a few weeks and when i returned it would randomly detect within mac then shutoff after a minute or so, rinse and repeat. When i tired in bootcamp it would sometimes detect at boot then shutoff after a minute or so. I gave up after a nights trouble shooting and when i tried again in the morning the display would not detect at all.
I've tried disabling auto adjust brightness, altered the power settings to disable the shutdown of hdd and displays, reseting the pram and vram numerous times, resetting the smc, installing and trying the different modes using gfx card status, updating firmware and all software, reinstalling osx.
I am very frustated at this point and any assistance would be appreciated.

Hi, I have the same issue : thunderbolt display screen switches off (but netwotk, usb still work). I see that the screen is very hot : is there any sensor that would switch off the display if temperature is too high ?

Well since I tried the "do not enable the powersave on the monitor" "Fix", it hasn't done it again. I still have the infrequent "go blank and come back", but I can live with that, annoying as it may be.
I wish I could set the power settings independently for each monitor, then I could "save" my MBP screen and let the TBM one "rot".
Yes, I have the latest updates etc. installed.

For some reason the display wakes up again when detaching all the cables apart from The Thunderbolt. First detached USB cables, no waking up display. Then detached ethernet cable and hey after restart the display turns on again...

I am so dissappointed with Apple for the first time. I purchased a 21" iMac 2 days ago, along with a 27" thunderbolt display. Everything worked flawlessly until today, I turn the iMac on, and the thunderbolt display won't turn on. Spoke with someone at Apple, did the unplug routine a few times (which I already did even before i called) and it was not fixed.
I don't get why all of a sudden the thunderbolt display stopped working, and after 2 **** days. I was using it the night before doing work and everything was fine, I did not do anything to it. So now, I had to book an appt with the genius bar, lug the display to the store in a cab since I don't have a car, and it would probably be a good idea to bring the iMac too just to make sure it's not the thunderbolt port on the iMac, so that's 2 huge boxes that I now have to lug around with me.
This, after spending close to $3000 2 days ago purchasing these products. I understand that sometimes things happen, but to have a defective product only 2 days after purchase is ridiculous.

I'm getting this problem with my Thunderbolt display and Macbook Pro (13", early 2011 model) ... So far, the Apple Store has replaced the lcd panel within the display itself which didn't work. They then replaced the logic board in my Macbook Pro and that didn't solve the issue so I'm going back in to see what's next. (My guess is the logic board in the Display itself...) Anyone else get this resolved 100%?

Was able to get this resolved 100%. Steps taken:
1) Post here
2) Create a ticket to go to the apple store.
3) Go to the apple store and they took it in for testing
3) Waited 2 days
4) They gave me a NEW display
5) Still had the same issues
5.b) Minor breakdown
6) Created another ticket to go to the apple store
7) I tested a used cinema display at the apple store. It worked!
8) Exchanged for a Cinema Display <-- The Fix
The reason I knew the cinema display resolved it for me is because I also run windows on my Mac, Windows was only able to recognize the thunderbolt display with a full reboot. Cinema recognized without a full reboot. I'm a little sad I don't have thunderbolt and Ethernet on the display, but i'll take a working monitor any day! Good luck!!!

Yeah, for me it got resolved by AppleCare Support in January. They swapped my old display with a new one. Since then I have had ZERO problems with it. My guess is the first batch of control boards of the TBD had some kind of problem that made them less than reliable.
The problem I faced was my Apple dealer didn't do anything about it, although they are obliged to do so by Dutch law. They claimed they have no backup by Apple in this respect and while I do sympathise with them I think they didn't do enough. It was quite a bad experience actually and maybe Apple needs to support these dealers a bit more, but I'm not really able to determine if that really is the case.
In the end it was AppleCare Support that contacted me themselves because they did read my posting(s) on this forum. After explaining the problem on the phone and some deliberation they swapped the display for a new one. I guess they rubbed me the right way and I'm pleased with the result.

Well, I just brought it in for the 5-6th time this afternoon. They are now going to swap out the logic board on the actual display. Crossing my fingers on this. The display is beautiful when it is not switching off randomly!

I love the thunderbolt features ... ethernet port, USB ports... Hopefully it doesn't come to this for me. Still holding out hope that the logic board on the displa swap out will work.

Just got my Thunderbolt display back from Apple after they replaced the logic board...Still turning off. So after the lcd panel, logic board in display were replaced and the logic board in my MacBook Pro were replaced, still no resolution.
