my sons ipod shows the apple sign and then occasionaly a white screen appears and then goes back to the apple symbol.. He cant get it to turn on.. He has tried charging it.He also held down the sleep/wake button and the home button at the same time to reset it. we need help

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- 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.
- Try on another computer
- 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 started making a movie and all was well. I added a few more pictures and some sound and played it back. It plays so far and then the pictures break up into colors and then the screen turns green. The sound continues.

I am making a movie from still pictures. I used no theme and then started adding pictues. When I played it back, all was well. Then I added a few more pictures and some sound. When I play iot back it plays just so far and then the sound continues, but the screen turns green or the pictures break up into colors.

Sorry, everyone. I think I may have figured out what it was all down to...........
I had left the IDE ribbon cable plugged into my third HDD, with the power cable unplugged. I did this so as not to endanger my years of work on the third drive, until Windows had setup. I have in the past, accidentally chosen the wrong partiton to format, so this seemed a good way to avoid it from then on.
This was not a problem on my old system, but it seems this system doesn't like it.
I must have left the drive completely unplugged, the times Windows did setup. Amazing really. I couldn't see the woods for the trees.
Anyway, I'm sorry to have bothered everyone with my problem.
Cheers
Marcus
edit : Sorry Syar2003, I didn't see your reply until I had posted mine. Many thanks for taking the time to try and help me, it seems as though I may have sorted it now. I am using IDE drives until I can afford SATA. But many thanks for the heads-up on the NF4-SATA compliance, I'll be sure to bare that in mind.
I didn't actually check the NVRAID/IDE ROM version before updating the bios, so I have no idea if the revision was changed when Liveupdate flashed the Bios, I'm afraid. I didn't know they would be updated at the same time.
Again, cheers

Hey there mtriest,
It sounds like you are unable to boot the iMac successfully as it keeps shutting down when you try to boot. I suggest the troubleshooting from the following article named:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/ts2570
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Perform a Safe BootSimply performing a Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
If your Mac starts up as expected, immediately try restarting.
If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
There is additional information in the article with further troubleshooting if needed.
Thank you for using Apple Support Communities.
Cheers,
Sterling

I tried to start my computer and just have a white screen. Does anyone know what this might be?

I tried to start my computer and just have a white screen. Does anyone know what this might be?

Not good news. But you will need to be more descriptive. What version of OS X are you running? Did you do anything different prior to turning it off the time before this happened? Is their an Apple logo on the screen? Is there a spinning gear below the logo? What version of OS X was installed when the computer was new?

I tried many times to turn it on, it turns and the same white screen appears and the update starts again and shuts down. Please Help me!

Hello!
I have a MacBook Air. I have got a software update notification couple of days ago. I've clicked on it today, and it started installing updates.
But, I have got a notification telling that not all updates were installed successfully, then I have clicked on "Restart" from the notification box. Then my Mac restarted and the white screen with Apple logo and the update progress appeared (like what always happens during updates).
The problem that while the update progress reached around half the way, my Mac shutdown. I tried many times to turn it on, it turns and the same white screen appears and the update starts again and shuts down.
Please Help me!

Welcome to Apple Discussions
You did not state whether you installed the update while on battery (not mains) power. You are warned not to apply certain updates without being connected to a charger & mains power.
Also remove any attached peripherals.
Reboot in Repair mode (command-R at start) and use Disk Tools-Disk Utility-Disk First AId to repair your disk, and as long as you're there repair permissions. Next quit Disk Tools and reinstall the OS. After completing that successfully reboot, log in and do a combo update.
You must have more than enough (not just enough) empty (free) disk space for the update.

My Macbook starts up, goes to the white screen with the gray apple, the little loading sign loads, and color wheel appears, and DOES NOT STOP PEIROD!
Even when I restart, shut it down; or when it runs down to no battery, when I plug in the power cord for a while, it loads up to the same stinking screen!
PLEASE HELP ME!

Restart the computer and immediately hold the option key down.
If the computer boots and you see two hard drive icons, use the arrow key to select the Recovery drive, and press Return.
You will get to a screen that looks like the image here:
http://www.apple.com/osx/recovery/
Select the fourth item and press Return.
In Disk Utility, select the hard drive in the left column, then First Aid, then click on Repair Disk.
When that is done, quit DU and restart the computer.

HT201401 Why does my 3GS have a white screen sometimes, and I have to lock the screen for it to go back to lock screen?

Why does my 3GS have a white screen sometimes, and I have to lock the screen for it to go back to lock screen? Sometimes I have to attempt the lock screen several times, and it still doesn't work. I, then, attempt to restart it by powering it down, and the lock screen will appear again. The display goes out sometimes while I am on a call, and I can't hang up. I have to go through this hole process over and over again.

The Basic Troubleshooting Steps are:
Restart... Reset... Restore from Backup... Restore as New...
Restart / Reset

Backing up, Updating and Restoring
http://support.apple.com/kb/HT1414
If you try all these Steps and you still have issues... Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step... Be sure to make an appointment first...

IMac will not get past chime & white screen

iMac will not get past chime & white screen. I have tried all the start up key combinations I can think of (d or c etc) with a start up disc, but no joy. The disc drives seems ok - you can hear it working & it will eject OK.
Any other start up ideas, please?

Have you tried a safe boot? If not, hears how (it's straight from Mac Help):
To start up into Safe Mode (to "Safe Boot"), do this:
Be sure the computer is shut down.
Press the power button.
Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

Hello all,
I have a 14.88G iPod Nano that I currently use as my primary watch. A week or so ago I started to experience a blank white screen when I press the "sleep/wake" button instead of the watch face (I have it set to wake from sleep to display the clock). When I hard reset it, it will come back fine and the screen will respond and work as normal, as soon as I manually put it to sleep by pressing the "sleep/wake" button and then try to wake it the same thing happens and I have a blank white screen that doesn't respond to touch gestures or anything.
What I have tried so far to no avail:
Numerous hard restarts (holding the "sleep/wake" button with the volume - button).
Tried this: iPod nano (6th generation): Hardware troubleshooting
Changed the watch face to display.
Recharged the device overnight (without full discharge).
Since none of this works I'm out of ideas. Eventhough I have a 6G Nano it should no longer be under warranty since I was sent it as a replacement for a different (older) product.
Any ideas? Is this a known problem? Thanks in advance for any insight any of you could provide. Also, what time is it??
Regards,

Hey,
I have the exact same problem as you have described. I also used my ipod as a watch but starting from today, whenever I unlock it the screen turns white until a reset is done. Even a factory reset through itunes didn't fix it.
Have you found any solution?
Bah, this is annoying.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
* https://support.mozilla.com/kb/Safe+Mode
See:
* [[Troubleshooting extensions and themes]]
* [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

My iMac started and locked onto a white screen. Rebooted and all was well. How do you do a safe start i.e. what key do you press?
