My thunderbolt display is not working

Just purchased a Macbook Air 13.3 and Thunderbolt display...everything is connected and the display will not power up.

which model air do you have?
try both a pram and smc reset
plug the monitor into a different electrical outlet and a different port on your Mac (if you have multiple tb ports)

My thunderbolt display is not working with my MBP retina 13''

Hi,
     I just received both a new macbook pro retina 13'' and a thunderbolt display. Everything was working properly yesterday but today, I have no clue why, the thunderbolt display is not working anymore.
     . the power supplier for my laptop given by the thunderbolt display is still working;
     . when I don't connect my laptop through the thunderbolt connection, I can use the usb sockets as power supplier , for my phone, for instance;
     . as soon as I plug the thunderbolt cable, the usb socket is not feeding any more my phone, whereas the screen is not displaying anything.
     . If I take a look in the system report, in the thunderbolt tab, there is "no device connected"...
I restarted plenty of time my laptop, took care to reinitialise the SMC as well as the PRAM, and nothing changed. I also disconnected the thunderbolt display, waited few minutes (and more), but nothing changed, again the black screen.
Has somebody an idea?
Thanks

The ethernet port on the thunderbolt display is not working

The ethernet is working when the cable is connected directly to my mac laptop but when connected the thunderbolt display there is no connection. Is there some type of set up for the ethernet connection or can this port just be broken?
Thanks for the help!

Afterthought on an older post: it isn't immediately clear that the Ethernet port on the Thunderbolt Display works through the "Display Ethernet" interface, rather than through the "Thunderbolt Ethernet" interface. The latter was already present in the list of network interfaces in Network Preferences, while the former had to be added via the + button --- at least that was the case when I installed the TB display to work with my 15-inch MacBook Pro Retina this week.
The AppleCare rep didn't know the difference either and agreed with me that it was puzzling that using the Thunderbolt Ethernet adapter on the Thunderbolt port of the display did work, wheras using the Ethernet port directly didn't (even though there were lights flashing on the Ethernet port of that other computer I tried to connect to in Internet Sharing mode). Close reading of the above posts made me go look for that mysterious "Display Ethernet" interface... thank you Clinton!

Thunderbolt display suddenly not working

I have a brand new MBP (retina), purchased about 2 months ago. I also purhased a 27in thunderbolt display about 1 week ago. The display has been working fine until tonight. When i tried to wakup my laptop from sleep the thundebolt display didn't do anything. I re-plugged all the cables and still got nothing. Rebooted MBP, nothing... shutdown MBP, still nothing.
Removed all USB cables from display, pulled power cord from display, re-connected, still nothing.
Went through the guides on here about reseting PRAM, NVRAM and SMC. Done all that, and nothing.
Also did the delete the /com.apple.windowserver.plist file... nothing seems to work. I can still charge the laptop from the display, but plugging in the thunderbolt cable does nothing at all.
Pretty ****** off, this display is one week old and it suddenly dies?
I have another display (dell) which works fine from either thunderbolt port from the mac.
Any thoughts? Is it the MBP or the display?
Software on MBP is Maviricks 10.9.2

So i left the MBP shutdown and the display unplugged from power overnight.
Connected it up this morning and nothing happened... left it connected and after about 10 minutes the display magically came to life out of no where...
Seems a bit dodgy!

I have 2 macbooks, and my thunderbolt display won't work on one. HELP!

I have to Macbook Pros. The one for my work is connected to my Thunderbolt. When I tried to connect my personal one to watch a movie, it won't connect. I tried "detect displays" and "gather displays" - nothing.
HELP!!

Welcome to the Apple Support Communities
Note that the Thunderbolt Display can only work with Macs with Thunderbolt ports (Early 2011 and newer MacBook Pro). If your Mac is older, it won't connect to this display.
To check what MacBook Pro you have, see > http://support.apple.com/kb/ht4132 If you have a Mid 2010 or older MacBook Pro, you can't use it with your Thunderbolt Display

Thunderbolt display do not turn on iMac 2011

Hi,
any idea why Thunderbolt display do not tur on iMac 27 (2011).
it turn on rarely (2 times from 10)
I also have conneced 24 Cinema display via display port

I believe AHT is a totally self-contained environment with its own (I assume very basic) video driver. I originally suggested a safe boot because that simplifies video too by suppressing quartz extreme. The ideas here were an attempt to minimize some of the video software involved. But the intermittent nature of your problem I believe indicates a hardware problem. And since it worked sometimes I'm inclined to believe it's the video card. It's not definitive, only my "feeling".
I don't think there is any more you can do at this point other than let apple diagnose it.

Installed Premiere Pro CS4 but video display does not work?

I just got my copy of CS$. After installing Premiere I found two things that seem very wrong:
1) video display does not work, not even the little playback viewer next to improted film clips located on the project / sequence window. Audio works fine.
2) the UI is way too slow for my big beefy system.
My pc is a dual boot Vista-32 and XP system with 4GB of memory installed and nvidia geforce 280 graphics board with plenty of GPU power. The CS4 is installed on the Vista-32 partition. My windows XP partition on the same PC with Premiere CS2 works great and real fast.
Any ideas how to solve this CS4 install issue?
Ron

I would like to thank Dan, Hunt, and Haram:
The problem is now very clear to me. The problem only shows up with video footage imported into PP CS4 encoded with "MS Video 1" codec. So this seems to be a bug. The codec is very clearly called out and supported within various menues but video with this codec just will not play in any monitor or preview window. In addition the entire product looks horrible with respect to performance while PP CS4 trys its best to play the video. Audio will start playing after about 30 seconds. And once in awhile part of video shows up at the wrong magnification before blanking out again.
My suggestion to the Adobe team: fix the bug and add some sample footage to the next release so new installations can test their systems with known footage.

Mac Mini + A1038 Cinema Display does not work

Hi,
I have a 2009 model Mac Mini with mini-dvi and mini-display port's on the rear. I can connect any of my DVI based monitors to the mac mini using either the mini-dvi to dvi cable or the mini-displayport to dvi cable. All monitors except for the A1038 model Apple Cinema Display.
The cinema display works with 3 other computers with DVI ports, turns right on and is detected right away. When plugged into the mini it does nothing. Sometimes I can get it to work with the mini-dvi to dvi adapter but that is sporadic.
This is the same behavior with a 2009 model mac book pro and macbook. Using the mini-displayport to dvi cable the cinema display does not work but 3 other monitors do.
So my question is, why does apple hardware only work with non-apple hardware?

Is the A1038 the old, plastic Cinema Display that doesn't have a power cord or power supply? It only has a video cable with the special ADC on it? If that's the case, it needs this to run from a newer Mac:

thanks!

The wish list only works on apps you have to pay for. To get it tap the icon of the app you want to save. After it opens at the upper right corner is a box with a arrow. Tap that then tap add to wish list list in the box that opens.

My iphone 4 fell down from 3 feet height and display is not working now, phone is functioning with calls and messages etc.. except no display :( please advise me a corrective action...

Take it to an Apple Store and see about getting an out of warranty replacement. I believe it will run you about $150.

Thunderbolt displays don't work with Mac Pro

Hello,
I got today a brand new Mac Pro with 2 thunderbolt displays.
Both displays stay black when I try to connect them on any ot the 4 ports.
Old displays work on the normal port.
Why does new Mac Pro with new 2 thunderbolt displays don't work?
Thanks.

If you can just wait until next year, Time Cook is promising a totally re-vamped Mac Pro which I have to assume will have TB ports.
My only worry is that today (Oct. 23) in the whole new slew of gadgets, Apple will introduce a new TB Display, compete with USB 3.0 ports, ant-glare screens, etc.
Sigh - you live with the technology that you paid for...

Thunderbolt display: devices not discovered after using Mini DisplayPort–to–VGA adapter

I have an interested problem related to using my MacBook Air in clamshell (closed) mode, connected to a Thunderbolt display. The problem appears to be related to moving my MacBook air between my office and my home.
At the office, I use the MacBook Air with an external VGA display, connected via the Mini DisplayPort–to–VGA adapter. At home, I use the MacBook Air together with a Thunderbolt display. An Apple USB keyboard is also connected to the display.
Mini DisplayPort–to–VGA adapter implicated
The following sequence of events causes the problem to occur:
Use the MacBook air (open) together with a VGA display, connected via a Mini DisplayPort–to–VGA adapter (depicted at right);
Put the MacBook Air to sleep by closing the lid, and disconnect the Mini DisplayPort–to–VGA adapter (I am not sure if the order of these two steps is significant—I usually perform them almost simultaneously when packing up my MacBook Air and getting ready to leave the office); and
With the MacBook Air still closed, connect it to a Thunderbolt display with a connected USB keyboard.
At this point, I would expect to be able to wake up the MacBook Air by tapping on the space bar of the keyboard. However, what I have observed is that this does not wake the MacBook Air.
I can wake the MacBook however by moving or clicking a Bluetooth mouse that is paired with the MacBook Air.
At this point, although the MacBook Air is awake, and the display is working, the USB keyboard connected to the display still does not work. This is the problem, in a nutshell.
Unplugging the USB keyboard from the display, and plugging it back in causes the MacBook Air properly to identify the keyboard.
I used Apple System Profiler to save a list of identified devices at two points in time:
Immediately after waking the MacBook Air by moving the Bluetooth mouse (at which point the USB keyboard was not working); and
After unplugging and plugging in again the USB keyboard (at which point the USB keyboard worked fine).
Many devices are enumerated in the second list that are missing from the first. For example:
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378ef, !registered, !matched, inactive, busy 3 (37993 ms), retain 6>
AppleUSBHub <class AppleUSBHub, id 0x1000378f2, !registered, !matched, inactive, busy 1 (37987 ms), retain 6>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378f4, !registered, !matched, inactive, busy 1 (37986 ms), retain 6>
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378f6, registered, matched, active, busy 0 (7 ms), retain 10>
AppleUSBHub <class AppleUSBHub, id 0x1000378f9, registered, matched, active, busy 0 (1 ms), retain 9>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378fb, !registered, !matched, active, busy 0, retain 7>
Apple Keyboard@fe112000 <class IOUSBDevice, id 0x1000378fd, registered, matched, active, busy 0 (112 ms), retain 11>
and many child devices…
Using the Mini DisplayPort–to–VGA adapter appears to be a necessary step to causing this problem to occur. If I merely disconnect the MacBook Air from the display, let it go to sleep, and then reconnect it again, the USB keyboard will work immediately and can be used to wake the computer from sleep.
Some devices are discovered even when the computer is in sleep mode. This is how it should work.
The problem appears to be that when a Mini DisplayPort–to–VGA adapter has been used since the last time the computer was connected to a Thunderbolt display, the MacBook air does not discover devices completely when it is again connected to the Thunderbolt display while in sleep mode.
Can anyone else reproduce this problem?

Hi glraczon.support,
It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.
Here is an article that may help you with that process:

Target Display Mode not working iMac 27(2012) Bootcamp to iMac 27(2013)

Hi All,
I recently purchased an iMac 27" 2013 which replaced my iMac 27" 2010.
===============
PREVIOUS SETUP
===============
(1) iMac 27" 2012 - Running Windows 8.1
(2) iMac 27" 2010 - Running OS X Mavericks
(1)+(2) were connected with a Mini-Display-Port cable.
(1) was using (2) as external display while (2) was set to Target Display Mode using CMD+F2
==============
CURRENT SETUP
==============
(1) iMac 27" 2013 - Running Windows 8.1
(2) iMac 27" 2012 - Running OS X Mavericks
(1)+(2) are connected with Thunderbolt cable.
(1) can't use (2) as external display anymore becuase CMD+F2 has no effect anymore on (2) in this scenario.
If (1) and (2) are both running OS X all works as expected.
I am aware about the support hint from Apple where they state TDM is not working under Bootcamp.
And I agree, while booted into Windows Bootcamp this machine can't serve as external display. Makes sense because TDM is baked into OS X display drivers.
Anyone had the same experience and came to a soltuion?
Thanks,
Martin

"Apple has no plans to implement a client driver for Windows since there is no Thunderbolt SW stack available for Windows like there is for Display Port."
That is a little bit funny since Gigabyte and other big companies have said that 2014 is the year that they are going to implement Thunderbolt in many motherboards.
"GIGABYTE 7 series motherboards are the very first to offer fully certified dual onboard Thunderbolt™ ports. Capable of connecting up to 12 devices plus 3 digital displays simultaneously with breathtaking data transfer speeds that can transfer 1TB of data in only five minutes, GIGABYTE Thunderbolt™ motherboards offer the fastest connection interface on the desktop PC."
Have you asked Apple about that? I dont understand why Apple is crippling Thunderbolt on their devices...
