What is wrong with my 30" Cinema Display?  The USB and FireWire ports still work, but the screen is pitch black. When you plug it into the computer, it detects that it's a Cinema Display.

When you plug it into the computer, it detects that it's a Cinema HD but the screen is pitch black.
For some reason, the USB and FireWire ports still work.

If you shine a really bright light directly into the screen can you then see a faint image on the screen? If so, that would indicate the backlight has died (hardware failure) and the unit needs repairing.

  • 20" Cinema display with USB and firewire ports not working

    I have a new 20" display and was wondering why my USB and fire wire ports at the back are not working. I have an external drive that is powered hooked up to the fire wire port and a no powered piano keyboard to a usb port.
    Any help please

    Verify that the display’s USB and FireWire cables are firmly plugged in to the
    computer. Do they show in your profiler?
    Try different ports in the computer.
    Verify that your computer ports are working with other known problem free device.

    Hello Korawees,
    I was researching the issue you are describing and had a recommendation. The device is very simple, so the software troubleshooting for it is pretty limitted so I think you shoud restore the iPod shuffle and re sync the content. That way, if it is a software issue, this will fix it. Here is the article named Restoring iPod shuffle to factory settings found here: http://support.apple.com/kb/HT1481.
    Before Starting
    It is important to understand the difference between "update" and "restore." Update does not affect your settings or songs, it simply installs updated software that controls iPod shuffle. Restore erases the disk and restores iPod shuffle to its original factory condition with updated software. If you only need to update iPod shuffle, this should be done on the computer where music is normally synced. Updating on another computer will result in all songs being removed from iPod shuffle.
    Warning: Because Restore erases all songs and files on iPod shuffle, make sure to back up any files you've saved on iPod shuffle. Your songs, podcasts, and audiobooks can be synced back to your iPod shuffle if the items are part of your iTunes library.
    How to restore iPod shuffle
    Ensure that you have an active Internet connection as new versions of iTunes and iPod Software may need to be downloaded to your computer.
    Download and install the latest version of iTunes if you do not already have it installed.
    Open iTunes, and then connect iPod shuffle to your computer.
    After a few moments, iPod shuffle will appear in the Devices section on the left side of the Tunes window.
    Select iPod shuffle under Devices and you will see information about it appear in the main iTunes window under the Summary tab/button for iPod shuffle (3rd and 4th generation) or the Settings tab/button for iPod shuffle (1st or 2nd generation).
    The Version section tells you whether iPod shuffle is up to date or needs a newer version of the software.
    Click the Restore button. You will be presented with one or more restore options that may prompt iTunes to automatically download the latest iPod Software. The 4-possible restore options are:
    Restore Option 1: Restore - Restores with same iPod Software version already on iPod.
    Restore Option 2: Use Same Version - Restores with same iPod Software version already on iPod even though a newer version is available.
    Restore Option 3: Use Newest Version - Restores with the latest iPod Software currently on your computer.
    Restore Option 4: Restore and Update - Restores after downloading the latest iPod Software on your computer.
    If you are using a Mac, a message will appear prompting you to enter an administrator’s name and password.
    A progress indicator will appear on the computer screen indicating that the restore process has started. Do not disconnect iPod shuffle during the restore process.
    After the restore process is complete, the iPod shuffle's status light will flash orange continuously. The iPod Setup Assistant window will appear asking you to name your iPod and choose your syncing preferences as you did when you connected your iPod shuffle for the first time.
    When you come to step 7, I recommend Restore Option 4.
    Take care,
    Sterling

    I have a desktop machine windows 7 based with CS5 loaded and working without problem. I have recently purchased a laptop running 8.1 windows.  I have loaded the cs5 package onto the laptop and it appears to work but when I try to update, although  I am being told there are updates it attempts to download the update but then tells me there is a problem and to quit and try again later.. I have tried a number of times to download the updates but itkeeps telling  me to quit and try later. what is wrong please?

    There could be a 32 bit vs 64 bit issues-is the old machine a 32 bit? and what is the new machine as far as 32/64 bit. I am not sure now if CS5 has in the help menu of the PS app the selection to update within PS if so that might work. I know that the Creative cloud app for installs updates  etc has caused me much consternation  over the last couple few years. Last it could be something like your Software firewall settings or  anti-virus anti malware programs. I know that updating the infamous adobe flash that Internet Explorer pop ups setting and having AV turned on as opposed to off can interfere or plain break the update ability

  • I tried to export photos from iMac to iPad using a USB flash drive.  The photos are on the drive but when I plug it into the iPad, the iPad says the device requires too much power.  Any ideas of what type of USB flash drive I should use?

    I tried to export photos from iMac to iPad using a USB flash drive.  The photos are on the drive but when I plug it into the iPad, the iPad says the device requires too much power.  Any ideas of what type of USB flash drive I should use?

    You can transfer photos outside of iTunes. I do it all the time. THat said, i have a 50/50 success rate with them. I'd avoid sandisk and kingston, their bundled software triggers the 'too much power' warning.
    I've had mixed luck with lexar, some work, some don't.
    I did have good luck with an older 4 gig geek squad one.
    Look for drives without software on them, without bright LED lights and I haven't gotten any larger than 4 gig to work, but that may just be me.
    For a less troublesome way? h onestly, I use a SD card that I've formatted with the DCIM folder. I've never had one of them trigger the 'too much power' warning. Just make sure they're not SDXC. those don't work.

  • The screen on my iPhone 4 turned black while i was using it-it was not dropped or damaged in anyway. The phone itself is still working as it comes up in itunes when I plug the phone into my computer, but the screen is completley black. What can I do?

    The screen on my iPhone has gone black while I was using it. It just "shut off". The phone is still working  as I can hear/see it when it plugs into the computer, but the screen just wont turn on. I've tried the soft reset "holding down home and lock screen" and i've tried to restore settings. I went to the apple store and they said I had to send it to my provider (in another country) but my phone contract has run out.
    Is there a way to fix this?
    If not, is there some way apple can replace the phone? It's less than 2 years old. Surely the screen shouldn't just give out like that.
    Thank you

  • Calendar on iOS 7. Anyone noticed that when you enter text into the "notes section" of a day, the text disappears behind the keyboard rather than scrolling down to keep pace with text entry ? Looks like an 7 glitch to me ?

  • My ipod touch has a permanent image of the end of a USB cable with an arrow pointing to an icon of ITunes. I can't reset, and ipod does not appear on itunes when I plug it into the computer.  This happened after I agreed to a failed software update.

    My ipod touch has a permanent image of the end of a USB cable with an arrow pointing to an icon of ITunes. I can't reset using the two button method, and ipod does not appear on itunes when I plug it into the computer - and nothing else happens either.  This happened after I agreed to a software update which failed.  How can I get it going again?

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    i don't know why it's all null. i assign something in the default constructor. it shouldn't be "null".
    does anyone know why?

    when you create 2 class using netbean editor, person.java and test.java
    i never compile person.java.
    when i finish typing these 2 class and i just right click test.java and run.
    my question is do i need to compile person.java before i run test.java directly??
    does Netbean compile it automatically when i run test.java first time?
    i add another constructor Person constuctor with one parameter in Person.java and create 2nd object to test the 2nd constuctor and run.
    All the codes work, so does the first default constructor. i don't why is that.
    Then i removed what i added and restore back to where it didn't work before and test again. it works.
    @_@. so weird.
    problem solved. thank you

  • I put my ipod touch in DFU mode, but when I plug it into my computer the restore your ipod alert does not come up in itunes. What can/should I do?

    I have been on the Apple Support page for several hours now and cannot find my exact circumstance and other suggestions have yet to help me. I purchased a locked ipod touch and when I plug it into my laptop itunes says "Itunes could not connect to ipod because it is locked with a passcode". The guy I bought it from told me the password but I failed to write it down and remember it and he has since moved so I can't find him. I have tried putting it in DFU mode and I can get it there, but then Itunes does not show the pop-up that everyone has said will come up with the alert about an ipod trying to restore itself so I cannot get it to do so. Any suggestions would be greatly appreciated!
    Thanks,
    AM

    When in DFU mode and connected to the computer iTunes does not say anything but iTunes will see the iPod and you can restore the iPod via iTunes. When in recovery mode and you connect, iTunes will say it found an iPod in recovery mode.
