My iMac screen is blue?

My iMac screen is blue? What can I do?? Please help!!

You can try repairing it but you will need to do so from either the original Install Disc that came with the computer or the Snow Leopard Retail disc. How you do that is insert the disc in the SuperDrive restart while holding down the Option Key and then select the disc. Choose the language, then click the Utilities Menu - Disk Utility and run Repair Disk. If it finds errors run the utility several time until it comes back error free. Then exit Disk Utility - Exit the Install process and try to restart normally. Obviously if it won't repair the HD has already crashed and needs to be replaced.
If you can get the machine to restart then BACKUP IMMEDIATELY!!!!!! if you didn't already backup. Once it is backed up then you can try to operate the machine. However IMHO your HD has either crashed or is getting ready to and you should be prepared to replace it.

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.

Your answer is likely in Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support If you are familiar with this document, please re-read it and I suspect you may find something you either missed or are doing incorrectly.

You could connect a FireWire Blu-Ray drive and use non-Apple player software.

IMAC screen freezes and goes blue....

this just started yesterday - I did not add any programs or update any software recently. I have since added Norton and scanned for viruses.
PROBLEM: my system freezes and the screen goes blue. It does not "wake" back up right away and after it goes blue a few times, it stays blue and I have to hard boot. If I leave the system off for about an hour, I'll get a few hours out of it before this happens.
DIAG: As stated above, I checked for viruses. I also ran all available diagnostics, and am fresh out of new ideas. Since I can't open my iMac without voiding the warrantee, I can't check for any possible burst or bulging capacitors. I disconnected all perperials and still have the same issue.
HYPOTHESIS: I am heavily leaning toward a hardware problem, but before I take the trip to the Apple store, I wanted to reach out to the forum to see if anyone else has had this problem?
This is an early 2006 Intel based 20" iMac that I have been running (24x7) since late August 2006. I never had an issue with my first iMac (pre-Intel).
HELP!!!

silentpartner,
Unless your issues match a known problem, (wouldn't appear too likely if no result from the Apple Hardware Test) before Apple will accept your iMac for hardware repairs, you'll have to prove it's not a software issue by reinstalling the OS. FWIW, if it's a hardware issue and in particular if the hard drive needs replacing, you'll want to back up your important data anyway, prior to turning it in for any repair.

My iMac screens broke it's not a new iMac it's old but it's blue behind it.

My iMac screens broke it's not a new iMac it's old but it's blue behind it. Does anyone know how much it would be to fix?

This is an international community. Prices vary from country, state, city, etc.
You should call the repair shop of your choice and ask for an estimate. Make sure the estimate includes taxes, labor costs, etc.
Remember, no one can give you an exact figure until the repair techs physically examine & run diagnostics on your computer to confirm what is wrong w/it.

IMac 27" i7 "blue screen" problem

Hello,
My iMac "crashed" a few weeks ago and I experienced something resembling windows "blue screen". The screen went black/grey/blue. Rebooting the iMac did not help and after the normal start up procedure (Apple logo) etc. the mac stopped at a grey coloured screen. I called support and together we tried every possible way of restarting the system without success. It seamed to be a hardware problem like a defective HDD drive or maybe worse. I received a list over Apple service partner and delivered my iMac for a thorough inspection. After approx. one week the service partner called me and asked me "what s wrong with your iMac?" Apparently the iMac started without problems and the diagnostic tests did not find any hardware failures. I was pretty surprised that they didn't find any hardware failure. Happy that the iMac seamed to be ok I went home and plugged in the machine. It started without problems. Connecting the wireless key board I discovered that most of the F functions did not correspond to the symbols on the key board anymore. All functions like brightness, mission control, dashboard etc. had changed places. While trying to reset to the F functions to the normal set of keys while simultaneously updating iTunes and the latest security update in the background the iMac screen went black and grey... It started once after the crash and I checked the list of incompatible updates in the appstore before it crashed again... Now the machine did not start properly and I got the same grey screen after rebooting the computer. I am relay disappointed.
Anyone out there experiencing the same problem? Anyone who can explain what's wrong?
I will have to call the Apple service partner again tomorrow.
My iMac is approx. 3,5 years old. i7 processor running OSX mountain lion with a 2TB HDD.
Best regards

Thanks for helping me out rkaufmann87
The iMac works at the moment and I have even installed the new OS X. I called the Apple service partner and they will look into the problem again. Now that they know what to look for I guess they will find the problem and fix it. Hopefully I will only need to change the HDD.
Back to the keyboard. What has happened to the F keys? I need to push the fn key in order to e.g. change the volume on the internal speakers or change brightness! What has happened to the default keyboard setup?
Best regards

My iMac turns on and about 10 mins later it glitches and freezes and then the screen turns blue/green/white

My iMac turns on fine, but about 10 minutes later I can't use the mouse as the whole thing freezes. Sometimes it continues to move the mouse for a while but then glitches the screen (see first image). After that my screen turns blue/green/white and even purple as a solid colour (second image - changes to a different colour). I'm wondering what the problem is and can I fix it myself?

I have a similar iMac.
1. Be sure you have 4 GB of RAM.
2. Create a new USER wih Admin Rights
3. Don't add anything to the start up sequence.
4. Update all your apps. This is a big problem. Do it.
5. Use Font Book and verify your fonts. Delete any broken fonts.
6. Download and install Applejack. If you have to force a restart, press and hold command s. A black screen will appear. Finally it will say something about Applejack. Type applejack and run #1 and #2. Restart.
Don't run Applejack outside of safe mode. (Command s)
Come back and let us know how it is working.

24" 2008 iMac screen going black

My 24" 2008 iMac screen keeps going black then coming back after a while. What temperature would it need to get to in order to knock out the display? I have iStat.
Also, if the screen fails due to graphics card or other component, is it possible to connect an external display to use it until I can upgrade to a mini?
Cheers.

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Reduced brightnes on half iMac screen.

Out of the blue the brightness of the display is constantly reduced on the top half of the screen.
It goes from being bright(normal) from the bottom and slowly faded into much darker at the top of the screen.
When it wakes from display sleep it appears normal in about a second then goes back to the split screen.
I have tried to reset the firmware, but it hasn't helped.
Hope someone can help.
Thanks

Ditto to Denny's advice! Run, not walk to the nearest Authorized repair center. iMac screens are about US$700.00 to replace if the warranty has expired. If you do not have Apple Care and your Mac is still in the original 1 year warranty, get Apple Care and extend the warranty for two more years. Just one costly repair will more than pay for the Apple Care coverage.

Every few minutes my screen goes blue! It has never done this before I upgraded to Lion.

I installed Lion last night, now every few minutes my screen goes blue! It has never done this before I upgraded to Lion.
Any ideas?

Hi Jack
Thanks for the reply. Thankfully, it has stopped now.
My iMac is quite new and less than half full, so I don't think deleting anything would have helped. Maybe the CPU was working too hard for a while ?
Just glad that it is now stable again.
