  • Thunderbolt Display - Image stopped working over night, while in sleep mode

    Hi All,
    Wondering if anyone has this problem?
    Been using TB display fine for over a year.  Connected into it are a couple of external usb hardrives, TB WD backup (which has a mini-HDMI monitor connected into it). The monitor has always worked well with the clamshell closed - seems like previous updates have fixed the odd phantom decision of which monitor should come on and when.
    Over the night, after putting the monitor into sleep mode, when I woke it up all systems kicked on (I could hear the external drives working and the other external monitor turned on), but no image came up on the TD display. My macbook thought it was on, as I could sweep my mouse over into it and initiate programs on that screen (but just not see them). 
    I unplugged everything from the display - still same problem, no image.  When I open my macbook up, while connected, it again thinks the display is active but there is no image.  When I sweep out, my macbook thinks the in-computer display is "Display 4".
    Because of the previous nuances with the TD display, I'm hoping hope that this is a software issue, but it kind of seems like hardware.
    Any insights would be great!
    Thanks

    Another update for you all....
    While watching a movie on the TV yesterday the Mac Pro and Thunderbolt display went to sleep and once again when I tried to wake them the screen was totally black. I called Apple again and the only thing they could suggest was to take the screen to an authorised service provider so that they can run tests.
    After going through the resetting of just about everything I got the screen working again.
    I then trawled through forums on various sites and can see that this is quite a common issue - especially if your connected computer is running Mavericks.
    Other solutions which people have used are plugging the power plug for the Thunderbolt display into a totally different power source (if that's possible in your set up). Thankfully for me it is.
    Another suggesttion which has worked for others is to disable the Power Nap feature within the Energy Saver perference pane.
    I did both of those and for the first time this morning the Thunderbolt Display woke up when I woke the Mac Pro!
    However I did get an error message that he system had recovered...

    Doing more digging in the internet I found this article
    http://sysadminblogger.wordpress.com/2013/12/02/os-x-mavericks-wake-for-network- access-with-no-random-wake-ups/
    So I am now thinking that not only has power nap been causing issues with the display but wake for network access is also not really working as Apple intend it to.
    As I am a home user there really is no need for me to need wake for network access enabled anyway so I am also going to disable that. Hopefully this will mean that I have no more random phantom wake ups which I think may have been the cause of this issue all along.

  • TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

    My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

    Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
    Long shot but...
    I wonder if it's a variation of this, of which I've seen many different symptoms...
    Resolution
    Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
    If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
    Additional Information
    This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
        1.    Open System Preferences > Security & Privacy > General.  Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
        2.    Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
    Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

  • Can't stop Thunderbolt display from flickering white lines after firmware update (Yosemite)

    I am having serious issues after the Thunderbolt Display Firmware Update 1.2. Running Yosemite on MacBook Pro and I am now getting white lines that gradiate from the bottom to the top of my screen across multiple browsers, apps and even the finder window anytime I move my mouse. I cannot take a screenshot (it stops when I try) but I posted a video here:
    http://youtu.be/3zOKL1JFp5M
    It is impossible to work this way and after 20 minutes of watching my screen constantly refresh anytime I move my mouse I am feeling nauseous.
    Is there anyway to UNINSTALL this firmware update? I was not having this kind of problem before. Every once in awhile I was finding my Thunderbolt display would not wake up after sleep and I thought the firmware update would fix that, not cause more, crazier problems. It is causing this gradiating line problem on my Thunderbolt display AND my MacBook Pro screen, which is even more bizarre.

    I updated and no issues with my 2012 Mini so may be computer related.  I believe once a firmware has been "burned" into the chip it cannot be redone.

  • Thunderbolt display image snowy

    I have my macbook pro (13-in, mid 2012) connected to a thunderbolt display with a second thunderbolt daisychained to the first. I am running OSX 10.9.
    Sometimes when my macbook goes to sleep because I have stepped away and I come back and wake it up, one of the thunderbolt displays has these snowy pixelated segments that appear on the screen. Sometimes unplugging and replugging in the thunderbolt cable will fix it, and sometimes I have to do a complete restart to get it to go away.
    Any ideas what may be causing this or what to try to fix it?
    Thanks!

  • New 27" Thunderbolt Display Flickers when attached to new 27" iMac

    I'm using a new 27" iMac. I require a dual-monitor configuration so yesterday I purchased a new 27" Thunderbolt display and plugged its built-in Thunderbolt cable into the Thunderbolt port of the iMac. I now have a huge desktop space that spans two monitors. With that in mind…
    At least once every few minutes the new Thunderbolt display blacks out (i.e. flickers) for approximately one second. The symptom is very similar to what a Windows-attached display does when the screen resolution is changed. A quick Google search indicates others are experiencing the same problem although most complainants are using a MacBook or Mini, not an iMac.
    Apple posted a firmware update for the Thunderbolt display a few days ago. I installed it successfully but the problem remains. Any advice?

    UPDATE:
    I received a call back from a senior tech at Apple. The salient points are as follows:
    (1) Apple engineers are well aware of the problem.
    (2) They plan to release a firmware update for the display at some indeterminate time.
    (3) The fix for this problem will not be bundled into the forthcoming 10.7.2 Lion update.
    Given that the flickering problem renders the Thunderbolt monitor virtually unusable as a desktop extension for a 27" iMac, combined with the fact that Apple has no idea when a fix for the problem will be available, my decision to return the monitor for a full refund is a virtual certainty.
    AppleCare objected to my conclusion that the Thunderbolt monitor is "incompatible" with the iMac. Perhaps they're right. I'm not super technical so it's possible that I used the wrong term. It's a semantic distinction though. The bottom line is that Thunderbolt displays flicker when attached to a brand new 27" iMac and my personal opinion is that one is better off not purchasing this device until Apple fixes this major flaw.
    Apple asked me to make a video of the Thunderbolt display manifesting the problem. Here it is.

  • Thunderbolt display problems using MBP with lid closed

    I am experiencing a very reproducible problem since purchasing aThunderbolt display to use with a recent (1 month old) Macbook Pro 13"2.7GHz i7.
    I use my MBP with lid closed with myThunderbolt display. If Ithen allow the MBP to sleep and power down, on restarting it the WiFi hasstopped working- the menu bar says I am connected by WiFi but Safari will notconnect to the internet and Time Machine cannot connect to the Airport/TimeCapsule to backup. Nothing I do will fix it (shutting down all programs, turingWiFi off then on) and so I have to shutdown/reboot BUT THEN the MBP freezesduring shutdown (waiting 15, 20, 30 minutes!) and I have to hold down the powerbutton (hard reboot). Once I reboot everything works fine UNTIL I take a breakand the computer goes to sleep again.
    Doesn't seem to be a problem with the MBP lid open, but I needto test this a bit more to be sure...
    On top of this the Bluetooth trackpad now keeps going on andoff; connected, not connected despite being near or the computer. Veryirritating at best, unusable at worst. This only started to be a major problem(every 10-15 minutes or so) when I started to use the Thunderbolt display.
    These problems seems to be in some ways similar to anotherthread:
    https://discussions.apple.com/message/16205098#16205098
    ("Major problemswith Thunderbolt display & MBAir")
    I have applied the recent Thunderbolt Firmware update, and SMC& PRAM/NVRAM resets. Interestingly these seemed to work initially but thenafter a prolonged power-down period the problem has recurred. Back to square 1.
    Any ideas out there?

    Just to be clear, have you installed everything that you find on this page?
    http://support.apple.com/kb/HT4644
    I just talked to Apple Care about Thunderbolt issues in general and even though I already had the Thunderbolt Software Update installed, he had me reinstall it.  If you go to this page:
    https://discussions.apple.com/message/16889000#16889000
    you can read in detail about the issues I was having which have for the most part been remedied (for now at least!)
    The Thunderbolt cable definitely transfers heat for some reason even when there isn't a high CPU utilization.  The process 'kernel_task' seems to be where the API for thunderbolt is running.  But for some reason, the behavior of CPU Utilization to Fan Speed is amplified when connected to the TBD.
    Apple Care is researching it.

  • Thunderbolt display wakes up to horizontal shreds

    After a few days of my new Thunderbolt display has a problem  - running with my mid 2011 11" MacBook Air (Lion / 1.8GHz Core i7/ 256 GB) .
    When the screen wakes up, it momentarily (3 secs) displays the screen in thin horizontal shreds. As if I ran the image through a paper shredder. Then it resolves to the correct image. Standard hook up to MBA with built in cords.
    I've read about problems with flickering screen - anyone else know about this?

    See if there is a way to turn off CEC on the Philips through its menu system and see if that helps.

  • 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.

  • Thunderbolt Display is constantly blinking on OSX Mavericks

    Hi folks,
    I got:
    - Thunderbolt Display,
    - Macbook Air,
    - Mac Mini.
    I am pulling my hair since my Thunderbolt Display started to blink (to black screen for half a second) every minute or so. Sometimes every 5 minutes or few times a minute.
    It started happening on OSX Mavericks. I thought  it could be only my laptop so I got Mac Mini (with OSX 10.8) from work and attached the display to it - not blinking at all. Then I upgraded OSX on Mini to Mavericks and guess what - now it's blinking with Mini too!
    Can anyone help me to diagnose the problem. Is there any way to check system logs to see for display (or thunderbolt itself) errors that might be causing this?
    I'm just unable to work because of this blinking and I'm frustrated as the display wasn't cheap :-/

    Did you check this thread:

  • My Thunderbolt display fan running unnecessarily

    For the last 6+ months, I have used the MBP retina (Yosemite 10.10.1) connected via lightning cable to a 21" Thunderbolt display.  My problem is that I have the fan running first thing in the morning when booting the MBP, as well as sporadically through the day.  Placing my hand on various parts of the display shows it to be quite cool, while the fan is on (and even when the fan is not on).  Nevertheless, the fan kicks-in regardless of:
    brightness set to 50% or set to 100%;
    use of 6 alternative spaces (of video desktop) or 1;
    CPU processing at 50% idle or at 95% idle.
    It is a complete mystery why the fan has to come on AT ALL.  I've been through the following display-related Firmware updates, but each exhibits the same issues.:
    Thunderbolt Display (September):
      Firmware Version: 22.1
      Port:
      Status: Device connected
      Link Status: 0x2
      Port Micro Firmware Version: 2.1.3
      Cable Firmware Version: 0.1.18
      Cable Serial Number: C4M2064015CDNWFA9
    Thunderbolt Display:
      Vendor Name: Apple Inc.
      Device Name: Thunderbolt Display
      Vendor ID: 0x1
      Device ID: 0x8002
      Device Revision: 0x1
      UID: 0x0001000100467B10
      Route String: 1
      Firmware Version: 22.2
      Port:
      Status: Device connected
      Link Status: 0x2
      Port Micro Firmware Version: 0.0.21
      Cable Firmware Version: 0.1.18

      Port:
      Status: No device connected
      Link Status: 0x7
      Port Micro Firmware Version: 0.0.21
    Any ideas?

    TBD fans are on all the time.  That is be design.  Don't worry unless it is making some strange noises.  I assume you mean 27" display and not 21?

  • Flickering problem with live viewing with IMAQ Image Display

    Hi everyone,
    I am trying to write a program to do live imaging with Andor camera. I am using some examples from Andor. The images are acquired in sequence and send into IMAQ Image Display and also Intensity Graph. There is minimal flickering issue in the Intensity Graph but there is very bad flickering problem in IMAQ Image Display. Perhaps I misunderstand how to optimize the vision tools. Does anyone know how to overcome this issue? I have attached the code that I am testing. Thanks in advance.

    You can use Vision Assistant to test our vision functions. Vision Assistant is really meant to prototype - it does not have all teh functionality of Vision Development Module and is not as flexible as we don't allow you access to all the settings for every function.
    I recommend starting in Vision Assistant and then porting over to LabVIEW or C (whatever you are most comfortable with)...this is built-in functionality. There is nothing wrong with using Vision Assistant to do live imaging, just that you run into limitations and you will only be able to use this code on computers that have Vision Assistant.
    Hope this helps.

  • Macbook, Thunderbolt display, Bootcamp problem.

    I have a Macbook Pro connected with Thunderbolt display. The Macbook has Bootcamp 5.5 and Windows 7 Prof 64-bit. When working in Windows the screen gets blank, but network and USB are still working. Sometime the screen of the Macbook goes blasnk also, not always. After that Macbook does not turn on when disconnecting the Thunderbolt display. This issue is also in OS X Mountain Lion.
    2 weeks worked without any problems, but this started yesterday and today the issue was too time consuming.

  • IMac 27" with Thunderbolt Display connected, Boot Camp Problem

    Hi everyone.
    Let me start off by saying that I'm using a late 2012 iMac 27", 3.4 GHz i7, 680MX, 32 GB RAM, 1 TB Fusion, with a Thunderbolt Display connected.
    I installed Windows 8 via Boot Camp, and it works just fine. Here comes my problem:
    I have dual screens and I play Minecraft. Minecraft's full screen is basically crap, and therefore I disabled the iMac display. I used Windows-button+P to use only the secondary display. This turns the iMac display off entirely, and leaves the Thunderbolt Display on. Note: This is not possible in Mac OS X. Then I played a little Minecraft. When I was done, i wanted the main iMac display to come on again. I then used Windows-button+P again, to turn both displays on. Then bam, totally looked like the iMac display was broken. See the images below, to see how it looks:
    1) http://cl.ly/image/1p2e3c1Z1z1C
    2) http://cl.ly/image/2g0n1M1Y0t0g
    3) http://cl.ly/image/2Q2P1c1J220d
    4) http://cl.ly/image/113b3K2O1Z43
    5) http://cl.ly/image/1q2v1s1n3w1f
    This image-retention-like stuff stays there, even if I reboot into Mac OS X, and then it eventually disappears. I can reproduce this, by doing the same thing again, (windows-button+p) but only in Windows, because that you cannot turn of the main display in Mac OS X. Maybe this is the reason why you can't?
    Anyone can tell me what I can do? I guess I could try reinstalling, but it seems more like a hardware issue, than a software issue.
    Thank you for your time, and thanks in advance.
    Another note: I'll try doing the opposite, and see if it happens on the Thunderbolt Display as well. (Windows-button+P, and then only using the main display)
    //ifraaank

    Ok, I am marking this as "answered", as I have solved it myself, while I still have no clue what lead to the problem in the first place.
    I've been on the phone with Apple Care today, and they were as clueless as I was and had never heard of this before.
    After we tried the usual stuff (unplugging all wires, PRAM Reset, SMC Reset), to no avail, I was told it could well be a hardware problem and that I should have the iMac examined at the Genius Bar, so an appointment was made.
    I'll cancel that one though, as I was able to cure it by myself for now (and carrying around a 27" iMac in Munich's busy downtown pedestrian zone is not really fun).
    This is what I did (and I'm so happy I tried):
    In Display Settings, I switched the external display back to landscape mode and selected "mirror displays".
    Then I rebooted, and voilà, the problem was gone (Apple logo on white background was showing).
    I switched it back to 90 degrees rotation and no mirroring, and it's still all ok.
    I booted Windows 7 in Bootcamp, then back to Snow Leopard, and it's all still fine.
    I can still only wonder what messed this up in the first place, but for now I'm happy.

    Hello,
    It is very difficult for us to "guess" what images you can read and what others you cannot.
    Maybe you could provide more information on images that are not displayed ?
    What is their native format ?
