Q: my 30-inch cinema display often doesn't come on at startup and I have to disconnect it and reconnect to work.

I have a 30-inch cinema display connected to a Mac Mini.  When I first boot up the computer after having it shut down for a couple of days, the display screen does not illuminate about half the time.  If I disconnect the display from the power brick and then reconnect it usually comes on, although sometimes I have to do that more than once.  It works fine once it on and displaying.  Anyone else seeing this?

    Hi Rocky Rakoon,

     

     

    Thank you for your post, and welcome to the Apple Support Communities.

     

    I understand that your Apple Cinema Display is not turning on upon startup. I'd like to reset the following, as it may resolve your issue:

     

    Intel-based Macs: Resetting the System Management Controller (SMC)

    http://support.apple.com/kb/HT3964

     

    You may also want to reset your computer's PRAM:

    Note: Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.

     

    For more troubleshooting directly related to the Cinema Display, see this resource:

    Thanks,

     

    Matt M.

    Replying to Matt00 and Rocky:

     

    I'm new to forums and hope I'm doing it correctly.

     

    I have been having the same exact symptoms as Rocky and if my more mature memory serves me well, Apple Care senior advisors already did a number of reset like things with me including ACL plus different preferences changes, though I forgot which ones....

     

    I am wondering a few things for Matt00 setup:

    (1) What year is your 30" ? And do you have 4 cords coming from it?

    (2) how do you have your 30" connected?

    (3) What additional connectors including adapters are you using?

     

    Last week I was in an Apple store re: my 30" intermittent illumination and a Genius told me that there is no 100% stable effective way to connect the 400 Fwire male from my 2006 30" into the 800 Fwire female port of my mid-2012 Mini BECAUSE the adapter  I have between them is for DATA transmissions NOT display transmissions (my non-tech wording). She said that this would account for the monitor illuminating sometimes and sometimes not.

     

    Wanting to know anyone's response to what I just wrote. How does this sound to you? Anyone try any creative ideas, or workarounds?

     

    Good Luck and Blessings for each of us working with this.

    Oops. When asking about setup, I used Matt's name instead of Rocky's. I was asking for Rocky's setup of course. Ty.

    hi,

    i've the same issue:

    i have a macmini i7, late 2012 connected via mini DisplayPort to Dual-link DVI Adapter with my Apple Cinema Display 30" (2006).

    i've also changed the cable but sometimes when i switch on the macmini i can see the image on the monitor, and sometimes it remains all black. To solve, i've to disconnect and reconnect the cable to my mini.

     

    Lightbear, have you solved?  i have this problem with mountain lion and also with mavericks.

    Hi Folks,

     

    To begin, sorry for my english wording, I am french.

     

    It seems we have quite the same problem.

     

    I have a "End 2009" Mac Mini (Core 2 Duo) with this fabulous Cinema Display 30".

     

    Problem is while awaking the computer after "a sleep" : frequently the screen remains black with the white led flickering 3 times.

     

    It comes back correctly only if I disconnect and reconnect the DVI Dual connector (not the power connector).

     

    I guess the problem comes from the synchronization between the Mac Mini and the Display through the DVI Dual adapter.


    I will give you the serial number of my DVI Dual adapter to check if we all have the same version.

     

    Regards,

    I have an MacBook Air on Yosemite.

    I also have that issue with my Cinema Display (2011/12 i think).

    Sporadically if i don't use it for a couple days i have to reset the SMC, Un plug Everything, Leave it for an hour, reset the PRAM.

    Not one of the items fixes it, I usually have to reset it multiple times. I took it to the store once they said just leave it unplugged for an hour. That only worked the first time.
