Thunderbolt Display turns off randomly

Tha Mac Mini Server of 2011 is the i7 quad core 2.0 GHz option. There were no other CPU options for the mac mini server version. In this case if you select that machine you will see two options for 16GB kits. One with CL9 and one with CL11.

The recommended one from Crucial is the CL11 (how ironic that could be???)

I would at least try the CL9 option - but I don't know that it will solve your problems... I've been following this thread for a while and it seems that there's simply a problem with some Mac mini's and the TB Display when 16GB of RAM is used.

But I would, if I were you, exchange it for CL9...

Yeap I intend to do that. The funny thing I have seen people saying that the problem went away when they switched to CL9 memory modules and especially the kingston ones seem to be popular.I will be waiting for Crucial to comment on it. Definitely though their modules are Mac compatible with an asterisk.

Also the funny thing is that when I ordered mine one year back I do not think there was the CL9 option there. But I can't be sure about it.

Well I swapped it with memory from another mini of mine and the issue remains (though it's not CL9). Only option left is to put in the original memory and see if it happens again, before spening money on another 16GB of RAM.

One weird thing I've noticed. When I try to reset the PRAM, it will only do it once and then go to a white screen and won't boot. No matter how long I holddown the keys and I have to turn off the power to be able to boot back up. Any ideas?

I haven't read all of the posts yet but it seems that my experience with the Apple Thunderbolt Display is similar to a lot of the users here.

Bought the TBD in June '12 and was satisfied with its quality look and feel. In May/June 13 I started having problems with booting the display and often had to turn my Mac off and on to get a picture. Then in August it went completely black. It was on (charged my Macbook Air) but no picture.

The repair shop just sent me the estimated costs today and - hold on - it will cost 200 $ more to repair than the cost of a brand new TBD. This doesn't make sense and I have politely declined the offer. And the warranty here in Denmark, when buying a product through a company, is 12 months.

In other words: I bought a premium product with a 12 month warranty and it dies after 14 months.

My advice to everyone who starts experiencing problems booting the TBD every now and then: Get it fixed before your warranty runs out! It will probably die, eventually.

I am going to call Apple Denmark Customer Support tomorrow morning and ask them what their policy is. My guess is that they won't care because the warranty has run out.

I don't know the exact amount I have bought Apple products for through the years. It's thousands and thousands of Danish kroner as I have used Apple products since 1990. In my view the quality has been dropping steadily the last couple of years. This last letdown hit the nail on the head and I will - of course - not buy an Apple display again.

Goodbye Apple. It was nice knowing you.

Hi,

I have this same display going blank on my TB display when I connect to the latest MB air. Am based in SF, any ideas on whats the fix, is this an issue with the mac or the display..? Is there a fix that we can do or needs to be taken to the apple store..?

thanks,

Hi,

I am kind of in the same situation like you. I was curious did you manage to fix the issue, what was the issue and how much did it cost..? and have you seen any issues after the fix..?

thx,

Hi Larry,

Whats the solution to the TB display going blank often..?

thx,

Checking if you had any luck with the fix..?

My solution to the issue was that it had to be taken in to Apple and have the logic board replaced. From what I'm told from the Genius Bar guys, it's a common problem. Mine was out of warranty, and I had to pay out of pocket to get it fixed.

I suggest that you should call AppleCare and notify them of the issue.

It won't fall under quality control repair until they get enough complaints, and we may all have a chance to get them to identify a quality issue.

How much did it cost to fix..?

The total was $185 and change. The total was for logic board and labor.

Last question 🙂 How long since its been fixed..? No issues since then..? and does the new board get covered under a 1 year warranty..?

It should be covered under the 1 year warranty, but you'll have to check with apple.

it's only been a couple weeks, but no issues since i got it back.
