IMac 24" brown patches on LCD SCreen

My iMac 24" has had three screens replaced since I bought it in May 2009. Dark brown patches appear and get darker in random areas of the screen. Since I am a photographer, it is a serious problem. The last replacement was only 5 weeks ago. Have many others experienced this issue ?

On a third replacement, I recommend asking for a replacement computer. Mention it has been for the same issue. Indicate how important even backlighting is for you. Remember, there is some glare in the display, make sure there is no light from behind or above you that might be filtering into the computer's screen. LaCie and other companies make light hoods for all sorts of displays. You may also want to get a second display with a light hood.

  • How much time an LCD screen can stay on and displaying images?

    Suppose I'm rendering on the new '27 iMac, how much time the LCD screen can stay on and displaying the same image? (Like the desktop, or a very slow progress bar).
    And, if there is a difference, how much time it can stay simply on and showing differents images?
    I have to use a screen saver? (but it consume some power to the rendering) If yes, after how much time? And what kind of screen saver, simply black screen or somethig animated?
    I have to turn off the display only? (but this can conflict with some particular software...) If yes, after how much time?
    Thanks.

  • LCD screen iMac

    Sorry if posting this topic here offends anyone but I was at a bit of a loss just where to post this query. It relates to cleaning the frequent smudges I seem to accumulate on my LCD screen. I checked at my local Apple shop who wanted me to pay an exorbitant sum to access a cleaner and wipes. A friend has suggested isopropal ( might ahve the spelling incorrect here) alcohol, available from a pharmacy. Not sure how it should be applied, any suggestions to this irritating problem, thanks

    You can use any well-washed 100% cotten cloth (a plain t-shirt or cloth diaper that's been washed a few hundred times fit the bill nicely). Dampen (don't saturate) the cloth with distilled water from any grocery, drug, or auto supply store and circularly rub the screen gently , doing a small area at a time.

  • Monitor Mirroring - iMac 24 with damaged LCD screen

    My iMac 24 LCD screen is damaged to the point where it is basically worthless. I have attached an external monitor via a VGA adaptor. Problem...since I cannot see the screen, I cannot get into system preferences to select "detect displays". Is there any way for the computer to detect the external monitor automatically? Or other suggestions. Thanks.

  • IMAC G5 LCD screen

    I am on my third LCD screen and I am presently waiting for another LCD screen which of course is back ordered. I have been told that this is NOT a common problem. I have approx 100 colored lines on my screen at this time. Has anyone had any success with a replaced LCD screen ? Or how many screens does one have to go through before Apple replaces the computer??????? From all the complaints it sounds like there is a big problem with the G5. I purchased mine in Dec 2005.....they came out with the new one a few months later.

    LUCYRYAN, Welcome to the discussion area!

    Mac and Mac models are picky about the RAM the Mac needs to see and use.
    As you have found out, the 1067 speed RAM will not work in your year and model iMac.
    You need the 1333 speed RAM.
    If, you can return the RAM for a refund, do it!
    If not, try online Mac RAM source and seller Crucial memory. They have a table that matches your Mac to the correct and reliable RAM. You may need to contact them to see whether or not they ship to South Africa, though.
    If Crucial dpesn't work out, here's the specs for your year and model iMac that you need to seek out and purchase.
    Maximum Memory
    32 GB (Actual) 16 GB (Apple)
    Memory Slots
    4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
    Good Luck!

  • Imac late 2013 lcd screens compatibility

    Hello everybody. I have an imac 21.5 inch late 2013. The exact model is EMC No 2638. It accidentally fell down and the lcd screen is very damaged. I want to replace it. The model of screen is LM215WF3 (SD) (D2).
    I want to buy this part but I found this model: LM215WF3 (SD) (D1).
    Can anybody tell me if it is going to work with mine?
    Another question. What are the models that can work with my mac?

    Hi gajonormal,
    Thanks for visiting Apple Support Communities.
    If you have not already, I recommend calibrating your iMac display:
    Adjust your display to show accurate color using Display Calibrator Assistant. The colors on your display can be altered by many factors, such as ambient light, the position and angle of the display, and the age of the display. Calibrate your display regularly to ensure accurate color.
    Choose Apple menu > System Preferences, click Displays, then click Color.
    Click Calibrate. Display Calibrator Assistant walks you through calibrating your display and then creates a calibrated color profile.For a more detailed calibration of your display, select the Expert Mode checkbox, which is at the bottom of the introductory text.
    Some displays have additional built-in color accuracy and calibration features. For more information, see the documentation that came with your display.

  • Can a LCD screen for a iMac G5 can be replace?

    Can a LCD screen for a iMac G5 can be replace?

    Thanks for the reply.  Soon after I posted, I found that solution.  However, the Airplay feature is not on my IMac. 
    I am very disappointed with the Sales and Service at the local Mac Store.  I was very clear about how I intended to use my network of computers and devices when I purchased the package.  It took two visits to the Support desk for someone to provide me with the Apple TV component.  And now I find that I don't have the Airplay feature on my IMac. 

  • My iMac 27" is 2 years old. The screen just start to sleep every 2-3 minutes and then one has to reboot it. I bought the unit from Incredible Connections in South Africa. They sent it to the South African distributors Core. They report LCD screen defect?

    My iMac 27" is 2 years old. The screen just start to sleep every 2-3 minutes and then one has to reboot it. I bought the unit from Incredible Connections in South Africa. They sent it to the South African distributors Core. They report LCD screen defect and charged me R7500-00 to replace the screen  and sent it back after 4 weeks.
    It does not  go to sleep anymore; but when switch on; there appears a flickering band of lines on the screen which last for about 20 seconds before the machines starts to work normally.
    It seems there is still a screen problem!
    We had to send it back again.
    The other problem is that you just get no communication out of the Core workshop and you cannot communicate with the technician.
    They had still not provide a technical report in spite of repeated discussion with the manager of Incredible Connections.

    Sounds like the graphics card might be the problem. Run the Hardware Test in extended mode. If you get an error it can be trusted, but getting a negative may not be all that meaningful.  Bring it back to them and let them check out the machine again.

  • IMac LCD screen replaced, Blue Screen startup

    Hi there, I just had the LCD screen replaced on my late 2007 Aluminum iMac today (due to a permanent red vertical streak) by an Applecare certified technician. He did a meticulous job with the replacement, and the iMac booted up just fine afterwards. About an hour later, though, I tried starting up the iMac and after the grey screen with the Apple logo it gets stuck on a blue screen with a constantly spinning pinwheel.
    Now I tried everything, booting up in Safe Mode, Single User Mode, resetting the PRAM, FSCK, Disk Utility using Disk Repair, unplugging the power cord for 30 seconds, etc. and nothing seems to work. It just gets stuck on a blue screen whenever it tries to boot up.
    Just wanted to see if there is anything else I could try out before I give Apple a call tomorrow, if this boot up problem is a result of the new LCD screen replacement or what? Any help or insight in the matter would be greatly appreciated, thanks.
    Update: I should note that right now I'm in the (lengthy) process of restoring from a Time Machine save to see if that helps out in any way.

    You could try the following first, but a repair may be required.
    iMac G5: Fails to startup (From an article at MacFixit)
    Some users are reporting an issue where iMac G5s fail to properly startup -- apparently at a hardware level -- never reaching the Mac OS X startup splash screen (Apple logo with a spinning progress indicator).
    Note that in cases where the system does reach the Mac OS X startup splash screen or further progression but stalls, software issues may be to blame.
    Potential fixes
    Disconnect external devices External devices -- especially those that draw power from the system -- can cause issues with startup that manifest either at the beginning of or later in the boot process. Try temporarily any external FireWire or USB devices then re-attempt startup and check for persistence of the issue.
    Reset SMU Although this workaround was not successful in Connors' case, resetting the iMac G5's SMU (system management unit) as described in Apple Knowledge Base article #301733 can resolve a variety of power-related problems, including sudden-onset startup failure.
    Check power cables Check your power cord for a loose connection. As noted in the aforementioned reader case, unplugging and re-plugging the power cord can sometimes result in a successful startup -- likely the result of a more snug fit.
    Also, power cables can become defective or ship in such a state.
    Try exchanging the power cable from a problematic machine with a system that starts up properly to eliminate this as a potential cause.

  • Help! Problems with LCD Screen.

    My iMac's specifications are below.
    Recently, I've noticed that there is this large patch of the screen which is covered with white bubble-like drops. I've tried cleaning the display, but it looks like they are under the screen. You cannot see them when the display is displaying white or other light colours. When displaying black or darker colours (even when the display or computer is off) one can see the drops.
    I'm not sure if it's because of something I did or what, but I want to know if I should take it in for repair, or if there is something I can do (It's still under warranty).
    Here are things I suspect:
    My iMac is usually under constant sunlight. It's not directly facing my window, but it does get hit my light. But I haven't heard of sunlight ever damaging an LCD screen.
    The drops seems to be in some areas, but not all. Which is why i doubt it's something I have done.
    When you get close to the screen, you cannot see the drops anymore. Also, when you are at certain angles, you cannot see the drops. This leads be to believe that a certain amount of light is need to see the drops, otherwise they are too faint.
    Any help would be appreciated!
    Thanks!

    Hello Kuro
    Take it to the nearest Apple Store or Authorized Apple Service Center, they can remove the glass panel over the display and clean or replace it if needed.

  • My LCD screen burned out. I have it connected to a tv now, but can't get the menu bar or the function bars to show up. Please help!

    My LCD Screen burned out, but the computer still works. I currently have it connected to an HDTV via, Mini DVI to VGA, VGA to VGA on the tv. Problem is, I can't get the function bar (maybe not the right term) or the bar at the bottom with all my programs on it. I get my screen saver and have managed to drag (by sheer luck since I can't see anything on my iMac screen) some of my pics I had on my desktop over, but nothing else. Please help!

    Hello
    you should have on your key board "mirroring key" , or F7 on old keyboard
    for now your tv is an extended screen for your imac not a miror , so you can not see menue barre on top of screen

    HOPE you are in 10.6

    "On some keyboards, you can press the F7 key, or Command-F1, as a shortcut to turn video mirroring on or off."

  • IMac 20" A1224 (EMC 2133) LCD bright grey but no video

    Hi All,
    I have an iMac 20" A1224 (EMC 2133) LCD boots up bright grey but no video, not even the able logo or spinning gear. After waiting the normal amount of time, the machine responds to keyboard input, i.e., I can change screen brightness and get the machine to beep at me by hitting various keys. I attach the external monitor and it works perfectly.. shows the desktop background after the computer boots up. I even booted the machine up to Ubuntu 11.04 GNU/Linux and was able to surf the Internet while looking at the externally attached display. All the while, the iMac LCD stays bright grey. The only time I see even so much as a flicker is when the computer boots up to GNU/Linux, where it flickers quickly once but then returns to bright grey.
    I've checked all the connections, I've run the command+option+p+r, I've unplugged the machine for over 12 hours and held the power button in and turned on power (to reset SMU), and I've disconnected the hard drive (shows a blinking folder if I have the external monitor attached and boot with the LVDS cable detached). I've even checked the LED lights - all four are lit.
    Very Frustrating!
    So now I'm left with trying to swap out parts.. An expensive idea to say the least!
    $24 Apple 922-8167 Cable, LVDS
    $250 ATI Radeon GPU
    $190 Apple iMac Intel 20" LCD Screen M201EW02 v.B
    Does anyone know a way that I can test to make sure which part to replace?
    Thanks!

    Oh and for those who might end up in this same situation... I was able to get the externally attached monitor to be the main screen by first unplugging the LVDS connection (from the LCD display to the motherboard), then booting with the external monitor on and attached. This is nice because now I'm able to use the computer as normal (while viewing it in the external monitor), and I can run a time machine backup. I tried mirroring displays, gathering windows, changing the resolution and brightness and nothing has yet brought back the video on the LCD panel.
    I still wish there was some type of testing software to check the GPU and tell me it's working perfectly... because then I could purchase the replacement LVDS cable / replacement LCD with confidence that replacing those items would fix the problem. Apple should attach these LCD panels with a DVI or HDMI connection internally... this way one could always (and easily) attach a monitor to the main output port and be able to easily isolate whether a video problem exists with the LCD/cable, or the GPU/Logic Board.
    Also, what's up with the replacement ATI GPU being $250+? That's ridiculous because I can buy a decent 3d-gaming capable PCI-X 3d graphics card for my GNU/Linux computer for about $80.

  • PS 7 and a new LCD Screen

    Which one is causing the problem: PS 7 or my new 22" LCD Screen? No matter how many times I remove preferences, I get the same results.
    Problem: All circles are printed as long ovals. What is designed looks fine on the screen, but when printed the shapes are elongated. To print them "correctly", I have to stretch out the circles horizontally until they print as circles. This is really dumb!
    Please help. LCD screen is great, I love it, but I must be missing something here........appreciate some helpful ideas................mm

    Well guys, this sure is the age of technology, but it's destructive when speed becomes the criteria of change instead of quality. I can think of lots of products that last 10 years or more, can't you? Oh, come on, software could be designed for better and longer use too. I can't help wonder if Adobe hasn't adopted the greed need for constant upgrades that don't work easily or well and require patch after patch for fixin'. Do we upgrade because it's really necessary, or to keep up with the Jones's, or just 'cause it's the latest thing to do? Please understand, I admire all who can keep up with the latest widgits and gidgits for whatever personal or professional reason, but let's not berate those who can't.
    So, thanks Dave, I took your suggestion and checked out Amazon and CS4 is reasonable. If I do get it, it'll have to sit on a shelf until this 'puter dies, and by then you guys'll be in CS 9 or more. I noticed it stated a different screen (1,024x768 display (1,280x800 recommended), and I just changed mine to native resolution for this 22"LCD. Now what?
    As always, many thanks......................mm
