Nano works great BUT screen remains Dark?

Everything works great, music transfers, playing BUT my screen remains very dark (but just light enough to see all the menu's and songs!). Messing with the backlight setting has no effect. Am I missing something or is it damaged?
I've updated the software and also used the restore feature but nothing can get it back. It's a 4G colour nano.
Any ideas?

also - i connected my digital camera straight to the monitor via USB and it doesn't display. I've never tried that before with my camera, but it seems like if the monitor is powered on, connecting it to the camera would cause the pictures stored in the camera to show up on the display.

  • IMac G4 screen remains dark

    my 17' G4 iMac USB 2.0 (10.4.11) screen froze and the following messages appeared:
    "System failure: cpu 0 00000008 unaligned stack"
    as well as lots of the following lines:
    "Unresolved kernel trap (cpu 0) 0x600 Alignment DAR" etc
    Had to shut it down by using power switch. Pulled out all cables except for mouse + keyboard.
    I can start it - but there is no start-up chime and screen remains black.
    Tried safe boot, no response. Tried to open drive door during start up for putting in hardware test disc (mouse held down), door won't open.
    Tried PRAM, no response. Tried PMU reset, no change.
    Removed extra RAM I had fitted years ago and tried to start it. After I did that the iMac responds
    with a 4 x beep morse code signal after turning it back on, but screen remains dark.
    Also tried to start in target mode, but other 27' iMac does not "see" G4 iMac.
    Anyone has any thoughts ? Don't want to get rid of this machine, I love the design.
    Thanks
    Walter

    There is some likelihood of a hardware failure, to include
    perhaps, the logic board; some kernel panic issues on an
    iMac G4 could point to such an event.
    Not certain if checking out such a machine at that stage is
    possible with the original Apple Hardware Test, since that
    relies on viewing evidence of the results in said computer.
    • What do the beeps mean on startup?

    While it may not be a major melt-down, you could be in for
    a project at some point in the future if you start looking into
    finding other similar iMac G4s (they are getting scarce) to
    use either for parts or as spares should their needs go there.
    I have two running iMac G4 1.25GHz 17" & one in-op for parts.
    A skilled and willing computer shop tech could probably
    test the computer further, but some shops would rather
    you buy something newer from their retail store. In some
    cases, you may be able to get a working iMac G4 17" 1.25
    for a few hundred dollars; if lucky, one in fine shape.
    Perhaps one of the techie folks who frequent these forums will
    see your post & offer their insights, based on experience.
    Good luck & happy computing!

  • Phone works great but when on a call proximity sensor kicks in turns off the screen. When I pull the phone away from my head screen is still blank. The force hangup/lock is the only way to bring the screen back on

    hi,
    phone works great but when on a call proximity sensor kicks in turns off the screen. When I pull the phone away from my head screen is still blank. The force hangup/lock is the only way to bring the screen back on.
    I purchaged it before one month onl. So i wont understand how it comes. Please help me. I am waiting for you reply.

    "Your face is so ugly, it broke your phone!" Ha ha. Get it? How I was joking there? About your iPhone not working correctly after... <sigh>
    But seriously, you said the situation only happens when you have been on a long call, so maybe the iPhone is just autolockng?

    i bought an iphone 4s of ebay and it works great but i went to set up a passcode but the person who had it before has put one on there and he can't remember what it is, is there anyway of resetting it

    If You Are Locked Out Or Have Forgotten Your Passcode
    iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
    iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
    iOS- Understanding passcodes
    A Complete Guide to Recover Your iDevice if You Forget Your Passcode
    If you cannot remember the passcode, you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and resync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
    Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
    Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
    Follow these steps to restore your device:
         1. Verify that you are using the latest version of iTunes before attempting to update.
         2. Connect your device to your computer.
         3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
         4. Select the Summary tab.
         5. Select the Restore option.
         6. When prompted to back up your settings before restoring, select the Back Up
             option (see in the image below). If you have just backed up the device, it is not
             necessary to create another.
         7. Select the Restore option when iTunes prompts you (as long as you've backed up,
             you should not have to worry about restoring your iOS device).
         8. When the restore process has completed, the device restarts and displays the Apple
             logo while starting up:
               After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
              to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
              iOS, keep your device connected until the "Connect to iTunes" screen goes away or
              you see "iPhone is activated."
         9. The final step is to restore your device from a previous backup.
    If you can not restore your device then you will need to go to recovery mode.
    Placing your device into recovery mode:
    Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
         1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the other end
             of the cable connected to your computer's USB port.
         2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the
             red slider appears, then slide the slider. Wait for the device to turn off.
              If you cannot turn off the device using the slider, press and hold the Sleep/Wake
              and Home buttons at the same time. When the device turns off, release the Sleep/Wake
              and Home buttons.
         3. While pressing and holding the Home button, reconnect the USB cable to the device.
             The device should turn on. Note: If you see the screen pictured below, let the device
             charge for at least ten minutes to ensure that the battery has some charge, and then
             start with step 2 again.
         4. Continue holding the Home button until you see the "Connect to iTunes" screen.
             When this screen appears you can release the Home button.
         5. If necessary, open iTunes. You should see the following "recovery mode" alert:
         6. Use iTunes to restore the device.
    If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
    Additional Information:
    Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.

  • I cannot send an email from my iPad 2? No problem receiving, why does this happen? Have tried the suggestions for setting up email and after doing the sync mail through iTunes receiving worked great but still cannot send? Any help would be great

    I cannot send an email from my iPad 2? No problem receiving, why does this happen? Have tried the suggestions for setting up email and after doing the sync mail through iTunes receiving worked great but still cannot send? Any help would be great!

    The fact that you can receive means you have a valid e mail address, and have established the connection to the incoming server, so all of that works.  Since the send does not work, that means your outgoing server is rejecting whatever settings you used formthe outgoing set up.  Try them again. 
    Google your particular isp, and ipad and many times you will find the exact settings needed for your isp.  Or tell us here, and soneone else may be on the same isp.  Some mail services need you to change a port, or have a unique name for the outgoing server.  
    Kep trying.
