My 27inch i Mac screen has gone darker all of a sudden. It's almost like a colour Burn and it's also washed out. Can anyone advise what the problem may be before I take it for repair?

Check the settings in System Preferences > Universal Access > Seeing > Display.
It's possible to alter some of those settings accidently by hitting the wrong key combinations.

  • Having just installed Firefox my screen has gone dark. Can I brighten the screen or not use it as my main Browser?

    Having just installed Firefox for the 1st time my screen has gone dark. I am on a MAC which also has Safari on it. I have made the Firefox the main Browser. Can I make my screen brighter or should I take off Firefox.

    Make an appointment at the Genius Bar of an Apple store. From the troubleshooting you performed and the hotness I suspect a hardware proboem.

  • Ibook screen has gone dark

    I'm helping a friend with a G4 i-book, about 3 years old I think. Today, while working on it, the screen went black. I think it may have gone to sleep but I cannot know for sure. I pressed the F2 key checking to see if he had somehow turned down the brightness but no change. I took it to the window and can see the computer is awake. Using the light, and turning the laptop at a side angle, I can see folders, etc. I went to the dock and found system preferences and clicked on display. The brightness was about half way so I turned it up but the screen stayed just as dark, almost impossoble to see anything. We shut it down and restarted it and while I can see it is on and awake, the screen is so dark you cannot possibly use it or see what is there without holding it up to light with an odd angle.
    I did do a search by many of the posts were about flickering or flashing dark. His screen has gone dark and while I can see things if I 'peer' carefully, the screen is black all the time.
    Any suggestions?

    Hey Michelle,
    Most certainly this is a inverter cable issue. Usually they open up near the hinge point. I've repaired two that this happened to. I have also seen two that shorted to ground and took out a tiny fuse on the logic board so after I repaired the short I had to bridge the fuse w/ a fuse link.
    Try moving the display up and down while it's on. If it comes on it's most certainly that cable.

  • OfficeJet Printer Pro 8620 - screen has gone dark!

    I have an OfficeJet Pro 8620.   Although it's still able to print, the screen has gone dark so I'm not able to fax or scan any documents.
    Need help ASAP, please!
    Naidia

    Hey @Naidia,
    Thanks for posting in the HP Support Forum.  I would like to assist you with your HP Officejet Pro 8620 e-All-in-One Printer's issue. 
    Just to clarify, is it that your printer display is too dark to easily navigate through the menu items, or is it completely black and non-responsive (save for the printing and faxing functionality you mentioned)? 
    The first thing I suggest is to plug the printer into the wall outlet directly if it is currently in a power surge protector or extension cord. This may sound silly but this will ensure the printer is getting full power and may eliminate any unnecessary troubleshooting. If the printer is no longer getting full power from the power surge or extension cord it may give false errors, have poor connection, paper feed issues and quality issues.
    Secondly, I recommending that you perform a 'hard reset': 
    Reset the printer
    Press the Power button () to turn on the product.
    With the product turned on, disconnect the power cord from the rear of the product.
    Unplug the power cord from the wall outlet.
    Wait at least 15 seconds.
    Plug the power cord back into the wall outlet.
    Reconnect the power cord to the rear of the product.
    If the product does not turn on by itself, press the Power button () to turn it on.
    Please let me know a little more about your printer's issue if these basic steps don't restore your display's regular functionality and visibility. 
    Thank you!

  • Ipod mini screen has gone dark, and when backlight goes on v

    Ipod mini screen has gone dark, and when backlight goes on the centre part with writing etc is almost black with light around edge. will this go? do i need to send it back?

    Maybe your backlight is burning out? That's what I would think when the center is black but the edges have light. I'm not sure if a reset would fix the backlight but you can try (hold the menu and center buttons at the same time until you see the Apple logo and then release). If I were I'd send it back to Apple but do you know if you are still under warranty? You should be if you've had your iPod less than a year.

  • Hi, when powering up my macbook pro, when the apple symbol appears the screen flashes pink, can anyone advise whats up?

    Hi, when powering up my macbook pro, when the apple symbol appears the screen flashes pink, can anyone advise whats up?

    You can try a system reinstall:
    Reinstalling Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

  • TS3274 My ipad2 is not responding..I want to restart it but i can get nothing but a black screen with only the apple logo and a small gear icon. It occasionally beeps but no other response.  Any ideas as to what may be wrong and what I can do?

    My ipad2 is not responding..I want to restart it but i can get nothing but a black screen with only the apple logo and a small gear icon. It occasionally beeps but no other response.  Any ideas as to what may be wrong and what I can do?

    Try:
    - iOS: Not responding or does not turn on
    - If not successful and you can't fully turn the iPad fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    Hello Mark Malecki,
    Thanks for the question, and welcome to Apple Support Communities.
    I understand you are having some issues with iTunes on your MacBook. You may want to isolate the issues further by testing to see if they persist in a new user account:

    You are correct, there is no flash player on the iPhone, find an alternate browser that may be able to help your quest.
    Or use the corresponding app in the App Store.

  • TS3274 My iPad screen has gone dark, but when I use internet it goes light please advise

    My iPad screen as gone. Funny greeny colour, everything including pictures are that colour, but when I use the internet it is normal. Please could you help. I've rebooted but no change

    Some folks here have reported that giving the back of the iPad a couple of sharp whacks has solved this issue - but you do this at your own risk. Best of luck.

  • My M500 screen has gone dark!

    I am having trouble with my screen. It goes dark almost immediately after turning it on. I get one second of normal screen brightness and then it "goes black". There does not appear to be a way to adjust the contrast -- which is what I think the problem is. Can anyone help me? I've tried resetting it and that hasn't seemed to work.
    Thanks,
    Kathi Jo
    Post relates to: Palm m500

    IIRC, you need to press and hold the power button for two seconds.  This turns the backlight on/off.

  • Screen has gone dark blue

    it started as green specs and weird resolution, now it's just gone dark blue.  No nothing. Am I toast?

    Have you tried rebooting? Hold down on the power/sleep button and the home button until the Apple logo appears on the screen? It raises about 10 seconds or so.
    If that doesn't work, restore the iPad via iTunes on your computer.
    I dont know what else to try other than restoring the device if rebooting doesn't work.
