Thunderbolt Display "dead" after firmware upgrade to Version 1.2

Hi,

I just run the Thunderbolt F/W update to 1.2 as offered by the AppStore Update. I have a 2014 MacPro with 2 Displays connected. In good faith I just confirmed to apply the update without much reading the fine print. The F/W update brought the system to a complete standstill. After 2 hours of waiting in the boot screen, I rebooted the system manually (5 secs power button). One of the Thunderbolt displays first just flickered, then decided to completely die. The System report says: unknown device in the Thunderbolt section. The 2nd display hasn't been updated during this procedure.


How can the F/W of the 'dead' display be re-installed? I also tried to connect it to a MacBook pro. Same result. The display is entirely black.


Any help or suggestion is much appreciated. Thanks!

You did't get the point


I was asking how I can post a general answer to be visible by anybody ( cause I did't get this option I can only reply to specific post like yours)

anyway now I see that this discussion is public so


First : if you think than apple does not moderate and look at this "apple.com" support your are naive

Second : my purpose was simple , the thunderbolt doesn't work at all with this new upgrade , it is completely non usable and apple didn't do something for months SO

If it is not a problem for you to have spend 1000 USD for a non usable monitor I think hundreds of people who get the same problem are not "happy" like you


Alone , we cannot do nothing BUT if we begin to have let say 40 people who can join us to explain to marketing team in apple ( easy to get contact via linked in ) , if we did't get a solution or if you don't give our money back or if you didn't change the monitor


We are 40 people and we will destroy our monitor ( cause anyway it is useless ) filming ourself and put than on you tube , with a SEO tags like WHY I destroy my apple thunderbolt 1000 USD monitor , I think they will take that VERY seriously , this can go viral in a few days , sharing by hundreds who will share again by hundreds.


I dislike to be a dollar chicken, PC monitor for 1000 USD you get the top of the top , I am working every single day on big monitor and I bought that **** to be Secure ( what a joke ) and it seems than they don"t care , they don't care cause you are alone with your problem facing a big corporation, but If we can join together to explain our problem BEFORE to do it , I guess we will get answers in a Few hours, if not all the marketing team of apple are plenty idiots , reputation is everything in the tech market

I've been struggling with problems with my two TBDisplays for a year now. I'm working with one Apple tech now for 3 months. I keep sending them data captures with failures on every different setup they would like me to try next. After two weeks of silence and no replies to my emails, the guy comes back with the error reports are inconclusive. REALLY. That is the opposite, the results are conclusive, the TBDisplays are failing with every possible setup they ask me to do. How is that inconclusive? Who do we have to call to get these displays recalled? Who do I have to call to get my money back? I'm tired of this crap. This is BS pure and simple.

Well my semi local Apple store manager surprised the heck out of me. I brought my two TBDisplays and computer and TB hub in for a couple rounds of genius bar tech time. After going over the last 3 month long case file, they came to a conclusion. They offered to refund me my entire purchase costs, including my Apple Care plan for the two monitors that I had for nearly 16 months............I jumped at the offer. I wished for this answer, but never thought they would do this. My online and telephone Apple tech said he couldn't make that offer, nor would he tell me who could. The bottom line is Apple knows there is a problem with the TBDisplays. My best guess is there are problems with the built in hub in the displays. Whatever was plugged into the hub, whether another TB display or another hub or the USB ports. Those devices always seemed to be dropped for various reasons. Whether sleep mode or start up or who knows what else. I feel rather lucky at this point. I can now move forward instead of doing the constant try this, try that approach. I had over a year of that type of trouble shooting. Never once did an apple tech tell me they were looking for problems here. But the store manager and genius bar tech were well aware of the issues. Of course me bringing in two TBDisplays, computer and stuff in their original boxes on a busy saturday, might have helped. It doesn't help business to make a scene with a store full of customers. Thank you Apple.

After a senior Apple Engineering Manager called me by phone back in Nov/Dec 2014 (yes, they called me in Germany from Austin, TX!) and asked for some data gathering, a support case was opened. Apple was kind enough to replace the display's defective logic board free of charge, despite being already after its warranty period. While being a disaster first hand, Apple took care of it. Thank you!

Glad to read they were so accommodating. Though keep an eye on the display. I had the logic board replaced as well and about a month after the same sleep/ blank display issues appeared again. They never could figure out what was causing the problem and they finally relented and gave me a new TBD. A month on and all is well with the new display.
