Intel Imac Screen Fuzz, Blinking then Black

I've been running windows xp on an Intel based Imac24 since October. Within a week I began having screen issues. The screen would start blinking and the colors would become fuzzy and pixelate a bit. Then the screen goes to black. After a re-boot it is normal for sometimes up to two weeks. It's seems completely random. I've talked to Applecare several times and because it's happening when running windows XP, they can't seem to help.
I did a hardware test and everything came out OK. I don't know if its a graphics card or hardware issue or whether it has something to do with Bootcamp. Anyone else with similar problems? I have upgraded to OS10.5 and all the Windows drivers are up to date.

"So this means my computer IS actually booting up, it's just the screen is not coming on! Now what?"
Hi debdesign!
Unfortunately, the black screen is simply a sign that the update didn't go through. An independently failed display at that same time would be quite a spooky coincidence:)
Refer to this Apple Support article: About firmware updates for Intel-based Macs
If it didn't update, then the Restoration CD needs to be tried again, or needs to be redone. I know you don't want to hear that, but if it didn't install, there's no other conclusion.
Think it through for a minute. It's most likely the case that your update didn't do the update. Also, your firmware restoration didn't go through.
Rather than blaming this on the warranty having just expired, it appears rather likely that there is a flaw in either your download or installation procedure. Read all you can, figure out what the weak link is, and correct it.
If you can't figure it out, you'll be paying a repair shop to do so for you.
Suggestions for you:
The update instructions include: "Quit all other open applications."
Turn off AirPort. AirPort is an application.
"I came to work and made the "Firmware restoration" cd."
You need to make it using a Mac. Best of luck:)

17" intel iMac screen froze then has gone completely blank. Any ideas?

Hi There,
My 17" intel iMac screen froze then has gone completely blank..
I've done a SMC reset to no avail.

Richard

If it won't startup in Safe Mode, then try Startup Manager or the Apple Hardware Test from your original Install Disc.

Both Memory Clean and Clean My Mac could have cause the damage which triggered the kp.
I would back up your Mac, erase and reinstall. Then Migrate your user data from the backup.
Uninstalling Tuxera is a troubleshooting process. You don't have to keep it uinstalled, just long enough to test to see if it is causing the problems.
However, if it doesn't happen regularly, it would be hard to determine if it was the cause. And, as I mentioned, I don't think it would be the cause.

Screen is blinking to black all of the time, it comes back but is constantly going black

I downloaded the updated firefox. since then the screen is blinking to black screen. At first, only every now and then, now all the time.

Are your Mission Control keyboard shortcuts being accidently pressed? Go to the System Preferences in the Apple menu to ensure you aren't pressing keyboard or trackpad shortcuts you aren't aware of.

Intel IMac screen black!!!

I have the first gen. Intel Imac, purchased March of 2006 (which makes the warranty JUST expired!) This is my home computer.
I am running 10.4.4
1.83GHZ Intel Duo
1.5 ram
2 days ago I was installing a firmware update, when the progress bar was right at the middle of the upgrade the screen went black. I wondered if it was done and restarting. I waited. Nothing. I finally restarted my machine, got the start-up chime, power light is on, but the screen remaned black.
I thought the firmware did not go through properly, so I came to work and made the "Firmware restoration" cd. Ran that last night, well, actually it won't run. No long "tone". Left the computer (on) for a while frustrated, and lo and behold from across the room I hear my screensaver come on (aquarium, you can hear the water!)
So this means my computer IS actually booting up, it's just the screen is not coming on!
Now what?????? (I am at work on my work computer now)

"So this means my computer IS actually booting up, it's just the screen is not coming on! Now what?"

Intel imac screen to Dell 2405fpw

I presently have a new intel core duo mac mini connected to a Dell 2405fpw 24" monitor which I love very much. But am thinking of getting an all-in-one machine and was looking at the 20" intel imac.
Am debating weather the 20" imac would be wide enought. How much of the screen area is there? I have not actually seen the computer except what I see online. I know it is much more powerful than the mini, but I just need a wide view area. the dell is considered a "wide aspect" monitor. what about the intel imac?
suggestions would be helpful.
thanks

I am considering the Dell 2405fpw with a Mac Mini for a relative. Any caveats? I have a 23" Apple studio display attached to my dual G5. I have had it for 2 years and am completely satisified. The resolution is 1920 x 1600. That is the same as the Dell 2405fpw 24". Obviously the pitch is different. There are lots of complaints in various places about anti aliasing and blurry fonts on the 17" and 20" iMacs. Try google/mac to get a sample.

Replacing Intel Imac Screen question!

Is it possible to replace a core 2 duo imac screen (20 inch) from late 2006 with the same size screen from the newer aluminum models in 2007/2008

No

My iMac screen went pixilated then went black

Hey!
So earlier tonight my 27" iMac (2009) went pixilated (green, yellow, blue, white small pixels) then the screen went black, but the computer was still running. I shut it down and turned it back on and I didn't have a problem until recently. After clicking play on a video on Facebook, the pixels returned and the screen went black again. I then proceeded to shut the computer down, but when I turned it back on, this is what I saw (refer to picture, sorry it's upsidedown)
The lines eventually disappeared along with the Apple logo, but the screen remained white for at least five minutes. I restarted my mac again, but the lines returned and the screen stayed white. That was around ten minutes ago and the screen is still white. What's wrong here?
Also, I recently upgraded to Mountain Lion about two months or so ago from Snow Leopard (either 10.8 or 10.8.1) if that's important at all.

Exact same thing has just happened to me! I believe I clicked on a facebook video as well; same pinkish strips and same white screen. My life and business is in this computer!

Imac screen error ( daken, looked black screen)

My imac has gotten error : I'd just heard start sound but couldn't see the screen .
After I push imac's start button which located back-left , it turned on !! Imac seems to start but screen just black not gray , blue...anything.
I 'd tried PRAM, SMC several times... and I even put memory chip out then cleaned these softly.
But it's still black.
I can see text, icons so hard through screen if I go very very closed...
Is graphic card problem? or monitor?
Please help me ㅜㅜ
Thanks ^^

Your graphics chip has failed, you need to take the Mac in for replacement of the logic board.

IPod screen went white, then black. Buttons don't respond, can't do 5Rs.

About 20 minutes ago, I plugged my iPod into my computer to charge, and sync some new music to it. It was fine when I plugged it in, the screen showed everything, etc. I removed some music from iTunes while the other music I wished to sync was downloading to my computer itself. After about 10 minutes the music finished, and I reopened iTunes to sync the music. I noticed my iPod wasn't on the sidebar, and checked the iPod itself. The screen was completely white, and I couldn't do anything with it. I unplugged it, plugged it back in, nothing. I pressed all the buttons, moved the wheel around, and heard some sounds, but then the screen turned black. Nothing is responding, and when I plug my iPod into my computer, it makes the sound to signal that I've plugged something in, but does not appear in My Computer or iTunes. I've tried the 5Rs, and some of them are even impossible since it doesn't show up in iTunes. Can anyone help?

If no joy... Try letting the Battery Fully Drain... Then Charge the Device for at least 30 Minutes...

Screen went crazy, then black - now iBook won't boot up. Help?

So, my iBook has problems. therefore I have problems. I was spoiled and grew up using macs as well as having a computer obsessed father who kept everything running smoothly... unfortunately I never took the opportunity to learn from him. So now I'm lost.
Problem started yesterday, screen went all vertical lines and flickered on and off. Rebooted, got to the login screen, same thing again. Rebooted, chime and grey screen. Reset PRAM, same thing. Started up off install disc, alllllllmost started all the way up... then colored lines, black. Reset PMU, still black, no chime now, just fan/ optical drive noise. Got frustrated, left it alone for a while, tried again and it worked!
THEN this morning in the middle of chatting, colored lines and black. Rebooted, just chime. Reset PMU, rebooted, and it worked!
THEN this afternoon... colored lines/ black. repeated above steps, but no luck. Currently all I get is a black screen and fan noise, no chime.
My iBook was bought July 2005, so it's just over a year old.
I'm not a computer whiz at ALL... but from things I've read in these discussions it sounds like it could be a logic board issue?
Any help would be GREATLY appreciated... I'm a broke college student

So, I suppose you've checked the link on the support page
http://www.apple.com/support/ in the lower right where you
can key in the computer's serial number, to see if you have
any AppleCare original coverage left...? The deal there is
with the extended optional policy, you get Support by phone
as well as Service repairs, for a combined period of up to
three years, total; including the first year's coverage.
If it is the matter of a few days, you could spring for the call
to AppleCare (pay per incident, out of warranty) and see if
you can get your issue covered, even though you probably
have lapsed official coverage. Sometimes sales support is
a way to go; other times, if you can get an AppleCare super-
visor; if you can point (hindsight?) to an issue that may have
grown into this current failure, that you were unfamilar with,
that now shows as a probable hardware failure... they may
be able to have the computer checked over anyway.
Out of warranty repairs are often expensive on compact and
portable computers where the parts are very hard to get into.
To get the computer tested and so on would cost you money.
If it cannot be booted from the included Apple Hardware Test
on the included media disc, someone else will have to do it.
Can your parents help you get a refurbished iBook G4 1.33 12"
from the Certified page online? Then, get AppleCare w/ in 11 mo?
These are less expensive machines than the MacBook on budget
and are significant in value as Certified units direct from Apple.
PS: I've owned only a few newer Macs; the total however is a
bit over 100 of them. At one time, I had over 40 in a room and
all of them worked very well; I restored them, & gave them away.

IMac screen turns white, then won't restart

24" iMac running 10.6.8
Just installed MacKeeper software and did a "Fast Cleanup". It says my system is running "excellent". Then, one day later, I am on the internet and the screen goes white. Pulled the plug as that was the only way I could get it to shut down, restarted, screen is now 50% white (frosted) but I can see the type. As I am talking to MacKeeper on the phone, it goes completely white again. Third time try to restart and button won't even turn it on. Fourth time restart (as above) and have the 50% white screen again. Long enough this time to figure out my Apple ID and password and type in this question.
Do you think this is software related (MacKeeper)? Or is this my first Mac to ever have a real problem.

Didn't get a response here, so I read some other similar posts. I've tried everything: rebooting to safe mode, uninstalling MacKeeper, and running disk utility (which said it could find no problems).
Any other suggestions out there folks?

IMac screen briefly freezes, then resumes

I have a late 2012 iMac running OS X 10.9.
Recently, I've started experience an issue where the screen will briefly freeze for about 5 seconds. It is frozen - no mouse movement, no keyboard interaction, and graphical animations stop playing. However, the computer is still working since music continues to play, and I can SSH in. After a few seconds, everything resumes. Interestingly, if I am clicking while its frozen (such as on icons or menus by accident), those actions have been performed, or if I type, the text appears.
Effectively, the screen has just frozen briefly, but the rest of the system is OK and responding -- its just not being sent back to the screen.
This happens perhaps 2-3 times each day. It is not linked to Time Machine backups.
Does anybody know how to fix this? I have tried restaring to no effect.
Thanks so much,

When you next have the problem, note the exact time: hour, minute, second.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above. Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first. Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough. It is never necessary or helpful to post more than about 100 lines. "The more, the better" is not the rule here.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

I have a 32in 1080p Sony Bravia. and a early 2009 iMac 20in. i bought a mini Dvi to HDMI adaptor. And i have the HDMI cable. but every time i connect my iMac with my Tv my iMac screen turns blue then back to the desktop.

i also click on detect displays and nothing happens.

You have the display set in Extended Desktop mode. In System Preferences>Display there should be an Arrangement tab when you have the TV hooked up to the MacBook and both screens working. Do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.

Why does my iMac screen keep switching off / going black?

After about one half hour of use my new iMac screen switches off / goes black.
The screen can be switched on by pressing the power button on the back on the machine a few times. It remains lit for about 20 seconds. This can comntinue for about half an hour when it stops switching off or when I give up.
I have conrtacted Apple but they have been unable to solve the problem.
The machine is just not fit for purpose as I cannot use it for work.
It appears from the internet that this is a recurring imac problem.
Please, what am I to do?

Call AppleCare (number is in the manual) and then request to speak to Customer Service. Be patient, organized and articulate and they will transfer you. When you get to speakt to someone then explain your problem and ask for their help. You should have all your receipts, invoices, trouble ticket numbers etc available for reference.
You can also take to an Apple Store in Spain, while this may not be convenient at least then an Apple person can see the machine and work on it.
