I'm getting a white screen when I launch my imac

Hello - I can't get my hard drive to launch. I tried unplugging the cord and restarting. I get the Apple tone but no Apple icon. Just goes to white screen.

Please complete your profile you don't tell us a thing about your system or the version of OS X installed. If you don't know how click Profile Update.
Otherwise the best I can offer is Gray screen appears during startup

I get a white screen when I try to enter iTunes Store

I get a white screen when i enter the iTunes store. The toolbar on the left is OK. The top is OK. It doesn't crash or anything, and I am logged in when I do it.

If you're seeing a blank iTunes Store, you could try resetting Winsock. That's fixed the problem for some people.
Click on your Start menu, go to accessories, and click the Command Prompt icon. Once it opens, type in the following command...
netsh winsock reset
Press Enter and it should say something like "winsock reset successful:
Then reboot your computer and try the iTunes Store again.
Hope this helps.

HT1414 iPhone works okay when charging but often gets a white screen when I take it off charge

iPhone works okay when charging but often gets a white screen when I take it off charge - I have tried resetting it and getting help online but the system asks me for an email address and my iPhone isn't set up for emails yet - if I got a text to trigger the automatic diagnostic service I could retrieve it from my 'poorly' device

First, update iTunes, then connect the phone to the computer and do a restore. This will also get your iOS up to date. Your phone should operate correctly after doing this, if not, you will most likely need to have the phone serviced or replaced.

Can't get past white screen when laotop is turned on

How can I get my MacBook to boot, won't get past white screen. Battery is fine.

Welcome to Apple Support Communities.
Sounds like it could be a problem with the hard disk.
You can diagnose and perhaps repair the problem (if the hard disk still runs, but has errors) with these instructions:

Just realized that you're running OS X 10.7 Lion

Getting a White Screen when trying to view ITune Purchases

Hi. I am using HDMI cables and when I go to watch anything I purchased on ITunes I get a solid white screen. I can view anything on YouTube just fine and could just look at movie trailers. Now I am getting a message telling me that the ITunes store is unavailable. But it is working just fine on my computer. I switched cables and am still having the same problem.
I'm at a loss. Any suggestions?

Hi,
While not an explanation of what is happening, I have had success restarting the device when this happens to me.

Get a white screen when I try to access phone on 3GS

When i hit the phone icon on my 3GS phone the phone goes to a white screen and then after a wait goes back to the home screen. I can sometimes get the phone number pad and other phone features to show up at least one time if I shut off the phone and then hit the phone icon when the phone is restarted. Anybody know what's going on?

If you're seeing a blank iTunes Store, you could try resetting Winsock. That's fixed the problem for some people.

Why do I get a white screen when playing movies?

Recently, for no apparent reason, when I play movies on my AppleTV 1st gen, the screen is completely white, no picture or sound. When I play TV shows, everything works like a charm. But whether they are movies I already own, or movies I rent, there is only a white screen and no sound. Anyone have any ideas?
Thanks,
AD

Try restarting the Apple TV by removing ALL the cables for 30 seconds, or resetting it using the reset option under general.

White screen when I turn the Satellite M50 on

I intermittently just get a white screen when I turn the computer on. Usually the problem is solved by switching the computer off and trying again - but sometimes I get a white screen again.
It seems to be connected to use of external devices - can anyone give me clear instructions about what should/should not be connected when I start and shut down the computer? Or any other suggested solutions?
Thanks

Thanks for your reply/advice - and the tip about Antivir. I used to use AVG and then Norton came as a package with this laptop....will have a re-think when my subscription need renewing.
I have updated the display/graphics driver but am still having the same problem of a white screen at boot-up. On reflection I think it is possibly a loose connection as I have just been a long trip with the laptop - including a fairly bumpy 4 hour bus ride - and I recall having the same problem several months ago which self-corrected after a similar trip (taking it down to a Toshiba ASP who never saw it as they were closed for the week-end and I had to get back to work!). This may sound strange but I took the laptop for a walk yesterday to see if any loose connection would shift and it then booted up on the second attempt rather than the 8th!
I guess I'll have to take it to the ASP - unfortunately it's no longer under warranty.
EDIT:
Problem solved. High temperature caused this issue

Won't get past white screen on shutdown/restart

When I choose shut down or restart on my 2012 rMBP, it logs out and moves to the white screen. From what I've seen, for an unlimited time.
When it does this (which I think is every time), my only option is press-and-hold standby key - which I hate doing!
This has been a problem since before Mavericks. I've tried resetting pram, repairing permissions etc etc. any other advice?
Even just a list of things to check which I may have already would be appreciated so I can discount them.

Been looking for a solution to this for ages and still no luck.
Even when I boot up in Safe Mode I still get infinite white screen when I shut down!!
