32 inch Cinema Display turns off repeatedly?

32 inch Cinema Display has taken to turning itself off afer 30 minutes operation.
Can this fault be repaired or should I be looking at buying a new display?

I have a 20" Cinema Display connected to an early 2008 MacPro. After years of service the monitor suddenly started going black, quite randomly. It would even happen part way through playing an edit from FCP. Strangely audio would be maintained though picture was lost. If I switched monitor power off and on again I would usually restore video image. Sometimes I had to do this power cycling repeatedly.
Looking through other posts it seemed a failure of the internal power unit was the most likely cause of the problem. But replacement seemed risky and not guaranteed. I considered buying a new monitor (probably a Dell UltraSharp since the Apple monitors are now so expensive).
Then I tried something else. In System Preferences and then Energy Saver I set the Computer Sleep slider to 25 minutes (I had always previously kept it on 15 minutes). Bingo! Problem solved.
Maybe this won't work for everyone but it certainly saved me some cash outlay. For now.

  • Cinema display turns off

    I have a cinema display attached to a 2008 iMac using a power adapter. It used to work fine, but now the cinema display randomly turns off and the only way yo get it on again is to unplug it and plug it back in.  What is the problem?

  • Older 20-inch Cinema Display powering on and off repeatedly

    I recently inherited an older (clear) 20-inch Cinema Display that I'm trying to use with my G5 dual 2.3 running 10.4.8. After purchasing the expensive DVI to ADC adapter and hooking it up, everything worked fine for about maybe 20 minutes or so until the display started to cycle on and off every two or three seconds (off for a couple seconds, then on for a couple seconds, repeat endlessly). This is accompanied by the power button glowing on and then off so it seems as if the power is cycling on and off by itself.
    Any ideas? At first I suspected the ADC/DVI adapter which got really hot when in use, but letting it cool down had no effect on the monitor's behavior. My clunky old 19" CRT display works with no problems, so it's not the video card. The Cinema Display is my old monitor from work, and never had any performance issues, although it's been in storage for almost a year.
    PowerMac G5 Dual 2.3 GHz   Mac OS X (10.4.8)  

    Same thing is happening to me. I have the 20" Cinema Display (clear with ADC).
    Last night I was in another room and all of a sudden I heard my G4 (Digital Audio) restart. I thought I was hearing things. Then about 3 minutes later I heard it again. I thought my daughter was up working on the computer or something. So I went up and there was no one around, but the computer kept restarting every 1 or two minutes. It was very strange – sometimes it it would go to sleep in the middle of the boot process.
    I was able to stop this process eventually by disabling the display power button in the Energy Saver and Displays prefs panels. But I would like this feature to be functional since it makes my setup easier to use for my kids.

  • 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?

  • 20 Inch Cinema Display Went Black

    i just rebooted my mac mini that is connected to a 20 inch Cinema Display and the monitor never came back to life. The screen is totally black and the firewire, USB and video cables are plugged into the computer fine. When I look at the computer on Remote Desktop from my laptop i can see that the mac mini is fine. i can also see that when i hit the on/off button on the display that it prompts the shutdown/restart popup on the mac mini so it is communicating with the mac mini. i have also plugged the display into my PB and again I get the shutdown popup when i hit the display's on/off button. is there anything to do to bring it back to life or is it dead? its not even a year old.

    Hey,
    Same problem happening here, You described it exactly. Even the magenta box. Mine also happens most in the open windows, not when the desktop. I am trying to figure out when exactly it is happening. The third item I have issues with is that blocks of data are 'stuck' in a genie expansion like motion so it is blurred and dot displaying in that 3x3 inch square section. Could have something to do with refreshing? Sometimes I notice the window will fix if I manually resize the window.
    Hope this helps any one who is trying to help us out.

  • Black band on my 30 inch cinema display. Any known causes?

    Hey everyone,
    My 30 inch cinema display is doing some wierd things which I havent encountered before.
    If you can see the image, towards the LEFT SIDE CENTRE, there are these BLACK BANDS.
    these start to appear after about 5-15 mins after the display is turned on. although they dont show up on bright backgrounds.
    If I let to monitor cool down for 10 mins and start it up again they are gone and they start appearing again in about a min or two,
    Has anyone seen any such issues before or is this a known issue with the 30 inch.
    Any ideas on what I should do about this.
    I will be taking it to Apple for sure as its still under warranty but would like to know
    what is causing this and whats apples take on it.
    Cheers,
    Ani

    I bought a 30inch as well a couple of months ago but have very little use except for watching movies. But when I use grey colour as the background the banding mark became very noticeable. It seems to be some kind of design issue i suppose and I dont know how Apple is going to address this. It's not a cheap monitor after all and i am very disappointed with this.

  • Is it possible to attach Samsung Monitor to the 27 inch Cinema Display?

    Hello,
    I have an Apple 27 inch Cinema Display and I also have a Samsung 27 inch monitor.
    I would like to know if it's possible to create a dual monitor setup by connecting the Samsung monitor (dvi or hdmi) with an adapter to the Cinema Display's mini display port on the back?
    Does anyone know if this is possible? Or does it only work with another Cinema Display?
    I'd appreciate any help received.
    Thanks,

    Is it possible to connect the PC to the Samsung monitor via Dual link DVI and to the Apple Cinema Display via mini display port and work as a dual monitor setup?
    That should work if the PC has both DisplayPort and dual-link DVI (or two DisplayPorts).
    I'm thinking the best solution for MacBook Air is to purchase a Thundebolt display and hook that up to the Cinema Display and I think then I would have a dual screen setup at full resolution.
    That will work if you connect a Thunderbolt disk drive (with two Thunderbolt ports) between the Thunderbolt display and the Mini DisplayPort display.
    But currently I don't think there is a way to connect a PC to a Thunderbolt Display.
    Not unless the PC has Thunderbolt.

  • Yoga display turns off after 1 minute

    I'm having an annoying problem with my new Yoga related to the display and have not seen any other posts with a similar complaint so perhaps this is a simple fix that I'm just not able to sort out on my own. My display turns off after 1 minute of inactivity. The only means for changing behavior like this that I am aware of is through the Control Panel Power Options. My settings for "turn off the display" are 10 minutes on battery and Never while plugged in (note screen shot attached). Regardless of my settings, the screen turns off after 1 minute. I've changed the settings to multiple configurations and restarted with no change in behavior. Perhaps there's some other settings area, maybe something specific to Lenovo that I'm not aware of (since this is my first Lenovo laptop). Anyone with similar problems or insight?

    This may be a Windows 8 issue. I finally fixed this problem by identifying the screen saver as the issue (and I wasn't using a screen saver). Type "lock the computer" into the search box after clicking the search charm, which brings up the screen saver dialog box. Mine was set to 1 minute, though I'd never set it myself. If you can't change it, choose a screen saver and you should be able to do so (and can then switch back to no screen saver). BUT, here's the problem. Other things you install (or settings within things you install) can apparently change and override whatever you type in for the delay time. Try applying your new time and exiting from the dialog box, then open it back up again. I was finding that it kept going back to 1 minute. To reset things so that you can get control again, type "user accounts" into the search box and when the dialog box comes up, choose "Reset Security Policies". Then you can go back to the screen saver dialog and successfully change the delay time. See http://social.technet.microsoft.com/Forums/windows/en-us/ace4085a-b0ba-4a98-898d-cd92d9e88e13/window... for some detail.

  • Random screen blackout 2009 24 inch Cinema Display... HELP.

    Random screen blackouts with 24 inch Cinema Display (purchased 2009). Never used with anything but same Macbook Pro (2009). No hardware changes on MBP. Just started June 6, 2012. Super annoying. Anyone else having this issue? Recommendations?

    Hello, Ertjie.
    The link titled Download the 24-inch LED Cinema Display Update from the kb/TS4045 article worked for me when I tried it today.  Click the "Download" link I post here or try the one in the kb article again.  Perhaps it will work for you now?
    However, I note that the kb article expressly states that this firmware update: 
    ...is only intended for use with and will only install on the Apple 24-inch LED Cinema Display while the display is connected to a Thunderbolt-enabled Mac. (EZ Jim emphasis added)
    If your Mac is really using Mac OS X (10.6.8)  as shown in your initial topic posting, your Mac may not be Thunderbolt-enabled.   If so, contact Apple or your Apple-Authorized Service Provider for help.

  • W520 - now changes to "projector only" whenever display turns off in power save mode

    I have my W520 in a dock with an external monitor. The display is configured to Extend - the external monitor is primary, and the desktop extends onto the W520 screen. I don't have a screen saver. I turn off the display after 30 minutes of inactivity. Until recently both the laptop and monitor screens would turn off after 30 minutes, and then both resume when I moved the mouse or pressed a key.
    Recently, the system has started changing to "Projector Only" when the display turns off. After resuming from power save mode, only the external monitor activates, and the W520 screen is disabled. I have to use Fn-F6 to switch back to "Extend" to re-activate the laptop screen.
    I have rebooted and re-saved the power plan.
    Why has this happened, and how do I fix it?

    Hi, timg11
    I have a few questions so that I may gain a better grasp of this issue:
    1) What is your machine type and model? You can find this information on the bottom of your machine. It should be in format XXXX-XXX.
    2) What is your operating system?
    3) Does this issue occur is the computer is not in the docking station? (Please try if you haven't already).
    Thanks in advance,
    Adam

    If the display has a DVI connector it will plug into the Mac Pro directly.  If it uses ADC (Apple Display Connector)
    <http://upload.wikimedia.org/wikipedia/commons/0/09/AppleDisplayConnector.jpg>
    you will need a DVI to ADC adapter

  • White Stripes/Display Turning Off

    Last night I noticed a bunch of white stripes flicker for about a quarter of a second on my display. This happened multiple times. I shut it down with no problems.
    Today I had no problems until everything froze. I could move the mouse, but it would not change from a text cursor. I manually shut it down.
    I turned it back on, after a few minutes I had the same issue.
    I turned it off manually, unplugged the power for about a minute, plugged it back in and turned it on. After a few minutes the white stripes flickered. I decided to back up everything. After about 10 minutes, during the backup process, the screen went black. I could feel that the computer was still on, but the display was black. I manually turned it off.
    I have now been on for about 30 minutes with no problems. The computer was very hot when the display went black. Is it possible that this is an overheating problem?
    Any suggestions?

    The iBook has a seperate display dimming (display turns off) and sleep mode timers. Go into the system preferences>energy saver to set these preferences. When your display turns off you should be able to reawaken it by pressing a key on the keyboard. Turning it off is not the best solution. If the problem happens while you are still using it or it doesn't awaken when you hit a key then you may need to post here again.
