Display going grey (fuzzy, losing contrast)

Hi,
I'm having problems with the display on my PowerBook. Basically the screen has lost contrast and crispness, and looks grey (see here for a picture -- hopefully).
I'm trying to work out what part could causing the problem. So far suggestions have been the inverter, the inverter cable, the screen, or the logic board. An external monitor works fine when attached. The screen brightness functions also work, although nowhere near the previous effect. When the screen faded originally the fade went from top to bottom of screen in about three seconds (not immediate) and it has been stable for a few months. The computer did get some water in it a few days before the screen went, although we tried drying it before turning it on.
Any ideas?
Thanks!
Sam

No: adjusting the contrast has an effect but we lose the fine detail. Maybe it is a brightness rather than contrast issue.
I am also assuming it is a hardware fault. There was a complete reinstall of 10.4 about a month before (total drive reformat). Oh, and the hardware test did not show up any faults (apologies for missing this out before).

  • 24" iMac from 2008 display went grey

    A couple days ago I noticed white single pixel height horizontal lines flickering all over my display.  I restarted the computer and it stopped but started again the next day.  Seemingly random flickering continued until suddenly the entire display went grey-ish.  Restarting does not help.  Thanks for any help! 

    Sounds exactly like what happened to my 24". The grapphics card is going bad. Most likely it will need to be replaced which can by done DIY for $250-$350. When mine first went bad I was able to use SMC Fan Control to increase the speed of the CPU fan, which would stop the freezing. Over time I needed to gradually increase the speed of the fan to keep using it. It lasted another 3 months or so before the card totally failed.
    All 24" iMacs had removable GPUs, so repair is possible without replacing the entire Logic Board. There probably won't be very many choices as to what card you can use. Sometimes the cards pop up on eBay, sometimes they are cheaper elsewhere. Although it uses an industry standard graphics slot, it simply won't work with a graphics card that's not specifically made for your model. When the NVIDIA chip went bad in my 2008 24" I chose to replace it with a cheaper and technically inferior ATI chip, because the same thing could have happened again, and graphics performance is not a big concern of mine. I got it from cwioutlet.com.

  • Display is Grey When Waking from Sleep Mode

    Anyone see this symptom. When we open the lid and the system wakes up, the display has a grey-ish overtone on the lower portion. It progresses and then brightens to normal operation. Is this the beginning of a display going to die? Thanks in advance...

    If the MBP doesn't wake when you open the lid but does when you press any key afterward, do this:
    Applications > Utilities > Terminal
    Copy and paste the following text in the Terminal window:
    *sudo pmset lidwake 1*
    You'll be asked for your admin password. Type that in (Note: the password will not be displayed as you do so). Press Return, and quit the Terminal. Close the MBP, wait for it to sleep, and open it again. Does it wake now?
    If you want to change it back so the system doesn't wake when you open the lid, repeat the procedure, but this time type or paste:
    *sudo pmset lidwake 0*

  • HT204291 Does anyone know why when streaming a movie from my iMac the screen on my tele goes grey but I still get audio. It only happens when using the DVD application on the mac. iPhoto streams fine.

    You are prevented from Airplay mirroring certain things like DVD content as the material is usually protected so you get a checkerboard type display.  I think there is a theoretical risk that the Airplay stream could be intercepted and the protected video copied, albeitin lower quality.
    Apple may be being cautious or are required to do so with the DVD player app by movie studios/licensing authorities.  It makes no sense to the average consumer who is just trying to send their purchased DVD to the TV via the computer and AppleTV.
    Playback in something like VLC should work - not tried it myself but others have commented it doesn't have the restriction.

  • My display goes off when Battery being charged on Acer E5-511 after upgrading to Windows 10

    I upgraded my window 8.1  to Window 10 on Acer E5-511 machine yesterday.  I notice that when I switch on power to charge its battery, a beep sounds and display goes off. when power is again switched off the display comes back with a beep again.  However, when the machine battery  is allowed to charge for some time, either it goes to hibernation mode or stops working since display does not come back even after switching off the power supply.  This peculiar problem did not existed when I had used this Notebook with windows 8.1 for past eight months.   Can any one help me to solve this problem as i am being forced to charge the battery only when Notebook is not powered on.

  • Display going black and/or squished at top

    I'm seeing a weird issue with my 27" iMac "Mid 2011" model, which I maxed out when I bought it (top-of-the-line i7 CPU, 2GB version of the 6970M GPU, SSD + standard HDD, etc.) and is currently running the latest Yosemite OS. As of a couple days ago, the machine will work fine for a seemingly-random period of time after boot (anywhere from 10 minutes to several hours), but then the display will either go completely black (though the backlight stays on) or (even weirder) the image will be "squished" into the top couple rows of pixels - the mouse continues to move (as best I can tell) and it seems that the machine is still functional, but the entire display is grey save for the garbled lines at the top.
    In both instances nothing I do can snap it out of the issue, including using the keyboard shortcut to reboot (which doesn't seem to work when this happens). Only a hard power-down / power-up cycle gets things back to normal, and then it will happen again after another random period of time.
    I strongly suspect something weird with the GPU, as I observed the same behavior while running the Disk Utility from the Recovery Partition (indicating this isn't some funky OS glitch), but I'm not at all sure. I'm going to make a Genius Bar apointment ASAP, but I'm super nervous about their likely findings, as my AppleCare ran out just a few months ago and a huge out-of-pocket repair bill would be a serious blow right now.
    Any hints / theories / suggestions?

    Hi there Huxley Dunsany,
    Issues with your monitor image behaving unexpectedly can be pretty worrying but I feel that these instructions from the following article should provide some help:
    Apple computers: Troubleshooting issues with video on internal or external displays
    Reset the system
    You can reset the Mac's parameter RAM and SMC.Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Thank you for using Apple Support Communities.
    Cheers,

  • Cinema display goes black upon resolution change in Windows XP

    Greetings
    Earlier today, I updated my ATI X1600 Radeon to the latest Windows Catalyst drivers and to the Catalyst Control Center from ATI. Even since, whenever a Windows application (games, in this case) tries to change the resolution on my external Apple Cinema Display (designated as the main monitor in the ATI Catalyst Control Center, with the MacBook Pro display disabled), the display goes black, and the monitor power lamp starts to flash.
    If I unplug the external Cinema Display from my MacBook Pro, my MacBook Pro display activates, and displays whatever it is I was trying to launch, so the problems is somehow related to the Cinema Display, even if the new drivers are causing it.
    This happens regardless of my Catalyst Control Center settings, such as scaling the lower resolution to fit the screen, or keeping it the original size, with black borders around. The problem does not occur when I launch games using 1600 x 1024, the Cinema Display's native resolution.
    Any ideas what might be causing it, and how to resolve it?

    Update on my situation: when I tried to change the resolution manually in Windows, I encountered the same problem. Now, whenever I connect the Cinema Display to my MacBook Pro, the same thing occurs: the screen goes black, and the power lamp starts flashing, even though I've changed back to 1600 x 1024.

    Can anyone help me connect my Macbook Air to a SAMSUNG TV.  When I follow the basic instructions (Thunderbolt to HDMI connection) the screen on my computer goes grey and an error message appears inviting me to press any button to restart the Macbook.  When I do this nothing happens.  Only when I disconnect the computer from the TV does the Macbook allow me to login. The TV does not receive any signal from the Macbook even though I know the HDI port works fine.  Any ideas what I'm doing wrong?  Do I need to enable something on the Macbook?

    An update...
    I downloaded Apple's (rather large!) list of software updates today, and I was finally able to recognize my iPod again. I did a restore using the iPod updater from 06-2006, and all seemed to work OK. (I'm afraid to try the new one again!)
    Then I tried to re-load my music library from iTunes, and got stuck. It froze up after a while and wouldn't go any further.
    When I disconnected my iPod from my computer, I find 2 podcasts and nothing else, though iTunes told me it had transferred 600+ songs. Those 2 podcasts do play fine, and the basic iPod software all seems to be intact.
    So -- anyone get through this connection problem and have any ideas to share??

  • My MacBook Pro won't start - it just displays a grey screen with flashing icon of a folder with a question mark in the middle. Help.

    It started while I was using Adobe InDesign, and that program froze, then crashed. When I tried to reopen the program, the error message I received was simply "Error: 16".
    I tried to take a screen shot of the error message for reference, and it gave me a message saying I couldn't because I didn't have access to the files where it would normally store the shot.
    Attached to my computer at the time was my Seagate Free Agent Go-Flex for Mac backup drive.
    So, I closed any open applications, and restarted my computer. But it wouldn't restart. It only displays a grey screen with a flashing icon in the middle of a folder with a question mark on it.
    I have no idea what happened - I wasn't using the machine any differently than usual, and it only had a few basic applicaitons open in addition to InDesign (like Preview, Text Edit, Microsoft Word, iCal).
    I have MacKeeper on my MacBook, and I keep it clean.
    Does anyone out there know what this flashing icon indicates, and if there is anything I can try on my own to fix it?
    Thanks.

    I have MacKeeper on my MacBook, and I keep it clean.
    Well that explains it, MacKeeper is almost malware.
    http://applehelpwriter.com/2011/09/21/how-to-uninstall-mackeeper-malware/
    Search the forums here for "MacKeeper" they will tell the whole story, crapware.
    Disconnect all drives, follow the "Grey Screen" instructions and hold Shift key down while booting, if you get into OS X , immediatly backup your files to another drive and disconnect.
    In my opinion you should first check to make sure you have a backup of your data, then just erase the entire internal drive (hold c boot off the 10.6 disk, use Disk Utility), reinstall OS X, same user name, update to 10.6.8, c boot off the 10.6 and Repair Disk (to fix a update error) install your programs and finally return files from backup into the same main user folders like before (Music, Docs, Pictures etc.)
    A pain it is, but you've hosed your system and in the process you might as well rebuild everything and have a fast machine again. So happens to clear MacKrapper, uninstall CS5 and any other junk in your system at the same time. Fresh, clean, lean and mean.
    Learn to Carbon Copy Cloner to a external drive that new pristine boot drive, you can hold the option key and boot from it (even update it), which is a real bacon saver when something like this happens.  Also it's free to use, donations accepted.

  • MacBook Pro retina display goes black while outputting video through HDMI to external monitor??

    I frequently connect my MacBook Pro to my 42inch Panasonic TV to watch movies/videos. I use VLC media player for all my playback. The problem I'm running into is that when I put VLC media player into fullscreen mode on my external display, my retina display goes black (I can still see the finder bar at the top and when I mouse down the dock appears but the rest of the display shows all black. If I click on Safari it will open but I can't see it on my MacBook display unless I take the external display out of fullscreen mode.
    I would still like to be able to do things on my MacBook while video is playing. I've played around with the display settings but they're pretty limited and I can't figure out how to get it to work the way I'd like. I've seen people having up to 3 or 4 displays hooked up, I'm just trying to hookup one. I would consider this a severe limitation of OS X if I'm not able to separately manage the displays. Hopefully there is a setting or something I'm just not seeing. Thanks.

    Yeah, fullscreen mode still doesn't play nice with multiple monitors. The common workaround is to stretch the window out to the edges of the screen instead of using actual fullscreen mode.

    Hello QuinnDev,
    Thank you for posting in the Apple Support Communities.  It sounds like you are trying to use your MacBook Pro with a Thunderbolt Display in closed clamshell mode (MacBook Pro closed), but sometimes the display doesn't stay on.  I found an article that talks about closed clamshell mode.  You would have to fulfill the following requirements to use your display this way:
    Requirements for closed display mode:
    Power adapter
    External keyboard, mouse, or trackpad
    External display
    You can find all the steps and the full article here:
    Mac notebooks: How to use your computer in closed clamshell (display closed) mode with an external display

    I hope this helps!

  • Mac mini 2011 display going black

    I just got my new core i7 + SSD 2011 Mac mini. I noticed during initialization of Lion and during a reinstall of Lion that my screen would flash to black for a second or two. A few days after installing Lion I still get this random flash a black a few times throughout my sessions. It usually only does it 2 or three times withing 10 minutes of turning on the the computer, then it seems to be fine. One time it flashed a few times and then the display went all distorted and pixelated. To fix it I ended up having to disconnect my 24" Cinema display and reconnect it. This whole display issue is really annoying.
    I found this so I hope Apple is working to fix this issue:
    https://discussions.apple.com/message/15843631#15843631

    Shutdown the Mini, turn off the display, disconnect and reconnect all of your power and display connections ensuring that they are fully seated and snug.
    It could also just be that the display going to sleep and then rewaking.
    1. Go to: System Preference / Energy Saver and check to see if your Display Sleep slider didn't maybe get set to under 3 minutes.
    2. Go to: System Preferences / Exposé & Spaces / Exposé and see if there isn't a Hot Corner set to "Put Display to Sleep" that you pointer might be going to.

  • Javascript - added images display as grey boxes

    I am attempting to add an Image to an InDesign document via a javascript that I am executing via the RunScript() soap method of InDesign Cs4 server.  The script I am using to add an image is something similar to this:
    var imageFile = File("//c/images/animage.pdf");
    var imageGraphic = myDocument.pages.item(0).place(imageFile, null, imageLayer);
    imageGraphic = imageGraphic[0];
    var imageFrame = imageGraphic.parent;
    imageFrame.geometricBounds = [IMAGE_TOP_Y, IMAGE_TOP_X, IMAGE_BOTTOM_Y, IMAGE_BOTTOM_X];
    imageFrame.fit(FitOptions.proportionally);
    imageFrame.fit(FitOptions.frameToContent);
    The script adds the image correctly, but when I pull up the document with InDesign, the Images are displayed as grey boxes.  I am able to fix this within InDesign designer by manually setting the "Display Performance" to "High Quality" through the menus, but I need to handle this via the script run on the server.  I attempted to update the script to the following:
    var imageFile = File("//c/images/animage.pdf");
    var imageGraphic = myDocument.pages.item(0).place(imageFile, null, imageLayer);
    imageGraphic = imageGraphic[0];
    var imageFrame = imageGraphic.parent;
    imageFrame.geometricBounds = [IMAGE_TOP_Y, IMAGE_TOP_X, IMAGE_BOTTOM_Y, IMAGE_BOTTOM_X];
    imageFrame.fit(FitOptions.proportionally);
    imageFrame.fit(FitOptions.frameToContent);
    //HERE IS THE NEW LINE
    imageFrame.localDisplaySetting = DisplaySettingOptions.HIGH_QUALITY;
    This script runs without problems within the CS4 ExtendScript Toolkit on my local pc.  However, when I run the script against the InDesign CS4 server, I get the following error:
    Error Number: 55
    Error String: Object does not support the property or method 'localDisplaySetting'
    Does anyone have any advice on how I should proceed?  My main goal is to have the image display correctly without the grey box.

    hello, I'm running into the same issue with image showing up as grey boxes. I'm updating documents via (JS) scripts by placing new images into rectangles. When I open up that document after the script saves it, all I see is a grey box until I change the Display Performance to Typical (or higher). In my scripts, I can change the localDisplaySettings to DisplaySettings.TYPICAL, but it only works locally, when I run this on the server it fails because it says DisplaySettings is undefined. I'm wondering if this is a server setting, and if so, how I might be able to change it?
    Thanks in advance!
