Intel OS X 10.7 iMac has white screen and three-alarm sound, won't start up
The 3 beeps during start-up are telling you that the RAM is bad.
If you can access the RAM modules, you may try taking them out and putting them back in, perhaps it's only bad contacts.
If that doesn't help, you'll need new RAM module(s).

20" Imac has white screen and freezes at start-up
my 20" imac will not start....help...All I get is a white screen and tone at start-up then it stays white. I tried hooking up a bootable firewire drive and pressing the alt/option key at start up nothing. I also tried the command/option/p/r at start up, it will reboot to the same screen. I also tried running the hardware diagnostics at start-up...no response. Computer was purchased on Nov .4 2007, warrenty just expired.
Help......Please....I had the exact same problem today. My iMac 20" (iMac 8,1) would't boot any more, staying stuck on a white screen immediately after the normal start-up chime. Nothing worked (no safe mode, no DVD boot, no disk selection icon when starting with alt pressed, no Apple hardware test, no parameter RAM reset, power management chip reset had no effect, no verbose mode, not even open firmware).
I browsed the forums, but what I found didn't help, so I was about to stop trying and have it fixed by Apple. But my son told me he had noticed that after "a long time" (he's 4...), a folder with a flashing ? would appear. I figured that wouldn't happen in case of a severe hardware failure, so I tried one last thing: I hooked up an old PowerBook in target disk mode via Firewire and restarted the iMac. I tried several times (with and without alt pressed), but nothing happened (when pressing alt, a functional mouse pointer would appear, though).
Then I restarted a last time and left the iMac sit there on its white screen for about 20 minutes... and that's when the miracle happened: it finally booted off the target-disk mode PowerBook's system!
I ran Disk Utility, which saw the iMac internal HD as disk2s0 (or something like that), and launched the disk repair process. After about three error-ridden verify-repair cycles, the green ok message finally appeared and the volume mounted as if nothing had happened. I rebooted off the internal disk without a glitch, and I still have to find damaged or lost files.
I guess I was lucky that my HD problem was benign enough to be cured by Disk Utility. But even if that had not been the case, at least I'd have known that the HD failed, and maybe I could have saved some files using recovery software. Whatever the case, if you've got an external bootable drive, it's definitely worth trying before handing your iMac over for (usually horribly expensive) repairs.
Good luck! -

Ipod touch has white screen and not responsive
ipod touch has white screen and not responsive, pls. suggest solution
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.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

21" iMac getting white screen and does not boot up
Hi All!
This is my first time to post here but have been using Mac OS since 2009.
I am having issues with my Mid 2011 iMac 21". I keep getting a white screen and it does not boot up.
I am a bit technical so I have done all the necessary steps as below:
1. Powercycle the system (Shutdown, unplug for 10 seconds and replug) = No go
2. Reset NVRAM several times = No go
3. Went to Safe Boot = Vertical white stripes on blue screen appears
4. Tried booting on Recovery Disk = Vertical white stripes on blue screen appears
I'm thinking my video card is faulty now.
Any help guys? I hope my hard drive is not fried
What's worse, my 3 year extended warranty just expired last June and it's only been 3 monthsFirst i can't send it back becuase it didnt have a warranty i purchased it on ebay. second the guy didnt send the install disks with it as he promised i have tried to follow up with him with no luck so hes been reported to ebay. and due to current buisiness expenses cant afford the new software. is there anything else i can do to at least boot the thing so i can figure out whats wrong with it. and has anybody experienced this before and if so how was the issue resolved. soooo frustrated as buisiness is at a stand still till this machine works. p.s.it has osx leopard latest version.

My MacBook Pro 13 won't start has white screen and beeps
I used my MacBook pro lastnight and worked fine. Tried to turn it on this morning and it won't start. Does sound like it is going to then before login screen shows ur goes to a solid white screen and beeps every 7 seconds. Need help school is about to start again.
Check this out.
I think you have bad RAM, so either you've recently put in new RAM, knocked some RAM loose from the socket (really hard to do), or the RAM went bad (maybe).
You might need to see a real tech.
Upon further review, I think your MBP has a serious problem. You need to take it to an Apple Store for repair. If you bought it within the last 12 months, you will be able to get warranty service, as long as you're not at fault. -

Hey Woolley13!
I have an article for you here that can help provide you with some further troubleshooting steps for this issue:

Try turning iPhone off and then on again.
If the iPhone will not turn off, try to reset it.
If that doesn't work, try restoring the device.

IMac has white screen after last update!
I am running maverick on my iMac. After this last update installed I am getting the white screen. It was working fine before. I have tried unplugging everything and restarting and that did not work. I have downloaded and reinstalled maverick and that didn't work. I have ran the disk utilities and the disk and permissions are good. When I am in the disk utility screen there are fuzzy about 1 inch lines running up and down the screen about 2 inches apart. And when I enter the disk utility start up the screen that is gray with the apple logo is all fuzzy. I have a time machine backup but it is a month or so old and I have a couple of files I really need to save if I can.
I Have gotten in using the left shift key forcing safe mode. There are still verticle lines up and down the screen.

6th gen ipod nano has white screen and won't go into disc mode
My ipod nano has a white screen - it will play music, and it is recognized by itunes. It won't enter disc mode. I can't seem to find any other helpful steps to follow online other than put it into disc mode and restore it via itunes. When I attempt to put it into disc mode holding power/Vol down together the screen will turn back, but when I then hold down Vol down/Vol up together while the screen is dark it just goes back to white screen. I did plug it into the computer and restore it via itunes, and the screen is still white. Any ideas? Thanks!
Hi LizS5,
It sounds as if you have already done much of the troubleshooting suggested in this article, but I would suggest you work through it in order to get your iPod nano back up and running -
iPod nano (6th generation): Hardware troubleshooting
http://support.apple.com/kb/TS3474
Specifically -
Try putting the iPod into disk mode:
Reset the device (press the Sleep and Volume Down buttons simultaneously until the display turns black—about eight seconds).
When the display turns black, hold down the Volume Down and Volume Up buttons simultaneously until the device enters Disk mode.
While the device is in disk mode, sync it to iTunes and try to restore.
And if the issue is not resolved -
My issue is still not resolved. What do I do next?
