Thunderbolt Display will not wake up after sleep!!!!!!

I've been suffering the 3 and 4 times a day of non waking TBDisplays. Maybe it is time for a class action lawsuit. The only course different from your efforts and mine are I haven't upgraded to yosemite yet. I didn't want to compound the problem or possible problems. My tech support guy won't return emails or phone calls. This is ridiculous. I have two of these monitors and they haven't worked from day one. I'm ****** and don't have the time to spend 3 or 4 hours on a online chat or phone call every day when this happens. I'd think they are too busy too, but yet here we sit.

I agree. Sitting around playing the "please turn back on game" with gimmicks that never actually work is insane. Compounding the issue with this has been going on for YEARS (see age of thread) is unacceptable.

Since there is no power button on TBD, unplugging and plugging the display cable from imac did the trick.

This firmware update may help.... Thunderbolt Display Firmware Update v1.2

Thanks for the reply, but it is up to date.

I took my TBD to an authorized dealer and they are replacing the cord. They think it is the thunderbolt part of the cord that is having issues. I'll be sure to follow up if this doesn't fix it.

I'm strongly considering purchasing this display to use with a mid-2012 Mac Mini. I don't really care about daisy-chaining TB devices at all. I might use a USB port occasionally but that's it.

Should I be considering a different display?

Thanks.

If you are not going to use the thunderbolt aspects of the display, it is a waste of money. Go buy a 1080p display for a couple hundred bucks. Even if you were looking to do thunderbolt hub work requirements, I'd still suggest going with a cheaper display until the current model is updated and improved after they iron out all the bugs. I'd return my two displays in a New York Minute if Apple would let me. So far I've spent a year "trouble shooting changes" with various tech support personel with zero results. Some of the problem posts for TB issues with these displays goes back to 2011. Go figure what Apple's priorities are?

Thanks, Dennis.

Just to clarify...

I would be using the display primarily for photo editing and would only use the TB to connect it to the mac mini.

I have to admit, after doing a lot of reading, there's a Dell monitor for $300 less that is looking more and more appealing.

I would be very careful about anything by Dell these days. From my reading over the last 3 or 4 years, Dell's quality and reliability have been reported as being lousy. I would do more homework and reading before going the Dell route. Samsung has always been a premium display maker. I'm sure there are others too. Maybe even HP. Check to see what Costco has and read their customer reviews. At some point Apple is going to need to update their displays to at least having TB 2. But more and more folks are going to 4K, so I wouldn't spend big bucks until I knew what I was going to be using for the next year vs. 3 or 4 years.

Thanks, Dennis!

Good luck with your display issues.

Do not buy. As you can see from this discussion, in this case, Apple's technology is seriously flawed. Therefore it should be rejected.

The display is beautiful, and a real work of art, with beautiful resolution - it just does not work correctly. Unless you want to waste endless hours trying to fix a problem that can not be clearly identified, do not purchase the monitor, because it has inferior engineeiing.

SONY makes beautiful displays.

Update: So far replacing the thunderbolt cord to my display has fixed my issue.

I have not had any issues ever since I turned off the option to "put hard disk to sleep when possible" in the Energy Saver control panel. Using Macbook Pro Reina.

Besides being a beautiful display, the main advantage is using the displays as a dock for a laptop computer. One cable and everything external is connected. Other wise you can get much less expensive HDMI displays. The main disadvantage for me is that Bootcamp does not support dual thunderbolt displays. Also there is a noticeable refresh delay with animation, such as Prezi presentations.
