  • IMac backlight OR LED Screen Panel Problem.

    So for about 6 months now i've noticed these 'smudge marks' people have been talking about behind the glass screen in my iMac 27" which is a late 2011 model (about 13/14 months old) and was bought new fro the iMac store.
    Then about 6 weeks ago i started having problems with what i thought was the backlight. After 5 minutes or so of being on my iMac, the screen would all dim a little and sometimes flicker for a fw seconds until it halted at a certain level of brightness (which i couldnt make brighter with the brightness volume buttons.) It became more frequent over the weeks and some times went completely black but i waited to take it into Apple because i live in Leeds UK and i knew there was a new Apple store being opened (Thursday 21st March 2013). Normally i would have to travel to the Meadowhall Centre (Sheffield).
    So sure enough, i went in on the open day and they took in my iMac telling me it was the backlight. They quoted me £109 including VAT whih i was willing to pay. I had a phonecall today 25/3/13 from the store telling me they had replaced the backlight and the problem was still occouring so they would need to replace the LED Panel. I was also told this would cost me over £300 + VAT! No way can i afford to pay that and i'm probably not alone when i say it took me long enough to save for the iMac itself! Theres obviously a serious issue with the backlights and LED Panels of iMacs dating back since before the iMac models first came about. I don't smoke, one of the 'Geniuses' in the Apple store even commented on how well it had been looked after, there are no radiators near my studio, it is very well ventillated and isnt over used, so this obviously isnt a case of not looking after it propely. I don't understand why i have to pay over £300 if this is a MAJOR fault with apples product and not mine. Tomorrow i have to pick up my iMac (still broken) and simply work with the problem which i'm pretty sure soon, will be almost impossible if the screen continues to go black and fail on me.
    Recap:
    My questions are these.
    What is causing the problems with the iMac backlight/LED Panel?
    Why have Apple not done anything about this fault since it's been going on years now?
    Why should i have to pay over £300 to fix APPLES FAULT.
    And finally, has anyone here won an argument similar to this that were out of warranty and not had to pay?
    Thanks,
    Billy.

    Hi Billy, sad, isn't it!?
    Some have paitiently worked their way through Applecare to get to a point where you can ask to speak to a customer service rep, & some have gotten satisfaction that way.
    On the LCD, I wonder if it isn't that LCD cable problem...

  • Please Help: iMac black screens after startup logo + spinning wheel no cursor).

    Hi, guys.
    I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
    I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
    I've tried rebooting over & over again; the results are the same.
    The steps that led to the problem occurred thusly:
    1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
    2 - One particular process I quit was 'launchd' which was functioning under my profile username.
    3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
    4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
    I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
    I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
    Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
    Thank you I'm advance to anyone with advice on how I can go about fixing this.

  • Eye Strain induced by LED screens

    I am an eye doctor in australia and have encountered an unusual amount of computer induced eye strain. What have others done to try and minimise this problem?
    There seems to be a big issue with the intense light of LED screens. Has anyone tried one of the new Benq no flicker screens in reading mode?

    I was having a lot of problems with my iMac and could only work on it for very short periods without my eyes hurting. It got to the point where I was going to sell it. I changed the colour temperature in Display settings from 6500 to 5250. The picture looked a bit yellow at first, but I soon got used to it and it is now very much better.
    One possible explanation is that white LEDs have a very different spectrum to normal white light (e.g daylight). They are usually made by coating a blue LED with a phosphor that converts some of the blue light to yellow. The combination looks white but the spectrum has an enormous spike in the blue. It is possible that this is more tiring for our eyes.
    The spectrum is shown in this article:
    http://en.wikipedia.org/wiki/Light-emitting_diode#Phosphor-based_LEDs
    I can't detect any flicker with the iMac screen. One way to test for flicker is to wave your hand rapidly in front of the screen. You get a "strobe" effect if it is flickering. Another way is to look at the screen through a digital camera (e.g. iPhone). Any flicker will tend to show up as stripes.

  • 2007 imac black screen...Graphics or Mobo issue ?

    First of all i would like to thank those whose postcount is solely made up out of recommandations to have better bought applecare or contact the good people from apple support for browsing away fromthis post without copypasting such advise.
    The problem is about a old 24" imac.
    Initially it stopped booting to the OS but still chimed, now i am facing a black screen, no gong at boot and the external white light illuminated permanently.
    After swapping around RAM and testing with known-good Ram of a same generation 20" imac - no change - i went and tried switching on without RAM ( now blinking light) which reacted like a known-good imac would without RAM.
    The one green led visible after taking away the screen frame and removing the screen ( but leaving both cables connected so the screen "should" still work) on the MoBo close to the RAM slot is not lit if i unplug the Mobo from the power supply, unplugging screen, screen inverter and data cable separately, disconnecting power and data to HDD and DVD drive all reasulted in the same solid white external light, one green mobo LED and no display picture or boot jingle.
    I then went to try connecting the power cable while the power button is pressed, resulting in all 3 fans at full spped and the hdd making seeking noises other than the incomplete startup noises earlier - but still white light and no display picture.
    This all rules RAM as error out, makes the MoBo and PSU less likely but still potential candidates and points to the graphics as commonly faulty area.
    Pitty is that the apple troubleshooting guide states it will be the motherboard as likely reason.
    I took a deep smell around the mbo and its dust when removing it, no clog-up ( yet lots of it) and more important no smell of a burned resistor or cooked hardware - a smell i know alltoo well from electric bike controllers and former shot PC hardware due overclocking.
    Now, question is/ are:
    - What white light or mobo LED blink code should i see on a faulty graphics identified in post ?
    Can a graphics card that is faulty halt POSt test with a white light as sole indicator ?
    -Does any of my tests done and LED lights shown rule out the Movo as faulty, leaving only graphics and faulty graphics power supply rail as possible reasons ?
    I could access another same imac to test the graphics card, but its a awfull lot of work.... if i could be more certain it is the graphics card and not the MoBo or PSU and if the CPU is likely give it the backing oven treatment, cross my fingers while tapping on wood for a few minutes and hope this refluxed the possible cracked G-DDR-Rams or the GPU`s soldering cracks tha appear to kill most older cards that do not go through overheating.

    if the fan is running very loud, the sensors are telling it to. this means there is excessive heat hitting them.  try hitting the on/off button on the back of your iMac gently, and turn down the brightness on your keyboard to 2 or 3 lines. use the F1 key on your keyboard to turn the brightness down, while pressing the on/off button lightly, without turning the computer completely off. if the screen image appears again, it could be the LED screen sensor is overheating, causing the fans to kick into high gear, to try to cool the screen. if your screen does re-appear with lower brightness, you can use an external fan control (SMC Fan Control) app to manually adjust the fans on your iMac. This won't solve the heating issue, but will allow you to use your iMac temporarily. As it is long out of warranty, you will have to find other means to find the remedy.
    So, in short, yes it may NOT be the GPU or logic board, but a heat sensor. let me know if lowering the brightness on your screen works to restore an image for you.

  • Mid 2010 MacBook pro took a keyboard spill.  It still works but display is sooo dark - like no backlight.  I think this is an LED screen.  Does anyone know the fix for this?

    Hi all...  My mid 2010 MacBook Pro took a keyboard spill.  It still works but the display is very very dark.  A faint image can only be seen at an angle in very bright light.  I think this model has an LED screen.  Can anyone please tell me what the fix for this is?  Thank you sooooo much!

    Spill Cleaning
    Some liquid has just spilled into your Mac. What should you do?
    Do
    Immediately shut down the computer and unplug the power cord.
    Remove the computer's battery (if you can)
    Disconnect any peripherals (printers, iPods, scanners, cameras, etc.)
    Lay the computer upside down on paper towels to get as much liquid as possible to drip out.
    Note what was spilled on your Mac.
    Bring the computer into an Apple store or AASP as soon as possible.
    Don't
    Don't try to turn it back on. Liquids can help electrical current move about the components of your Mac in destructive ways.
    Don't shake the computer (this will only spread the liquid around).
    Don't use a hair dryer on it (even at a low setting a hair dryer will damage sensitive components).

  • Since itunes 2.0.4 has been downloaded. My ipod doesn't synchronize properly/ at all.The LED screen shows  "copy 1 or 2 from 101" and it will remain like that. It looks like sync but there's nothing to happen. It doesn't stop by it self. How to solve?

    Since itunes 2.0.4 has been downloaded my ipod doesn't synchronize properly/ at all. The LED screen shows çopying 1 or 2 from 101' and itt will remain like that.
    It looks like sync but nothing is happening. The sync doesn't stop by itself. Is there anybody to solve this problem? In previous versions never a problem.

    I have exactly the same issues with my new 80G iPOD. I have found that when connecting to my PC, the iPOD does not start iTUNES 7. This can be resolved by stopping the iPOD Service in Computer Management, connecting the iPOD and then starting it again. Then when you start iTUNES it finds the iPOD. - http://docs.info.apple.com/article.html?artnum=93716
    Seems like a stupid long-winded way to do things, but at least you can get some stuff on to your iPOD.
    As far as using Restore goes - I just get the restoring iPOD message you described, which it blatantly isn't :((

  • Upgraded to Yosemite and can no longer remote into my work iMac through screen sharing- it is turned on in settings?

    My screen sharing functionality did not show up in the dock with an updated icon.  It had a question mark- shows my connections but nothing works, I did make sure screen sharing is on and also connected to VPN.  Once I tried to launch screen sharing nothing happens.  Such an elegant solution in Mavericks not does not work. Ugh. Help!

    This is the post that got me set up- I too am running an older version at work vs. Yosemite. As soon as I followed is advice everything worked.
    Upgraded to Yosemite and can no longer remote into my work iMac through screen sharing- it is turned on in settings?
    I believe the location of the "Screen Sharing" app has changed, which explains why if you had it in the dock it has been replaced by a ?
    Don't forget you can launch screen sharing (once your VPN connection is up) by typing in the Safari destination slot vnc://remotemachinename:portnumber  (omit the :port number if you are using the default VNC port, 5900).  This should launch Screen Sharing and put its icon in the dock.  You can drag the Screen Sharing icon to the left of your dock and it will hopefully remain there after you exit Screen Sharing, or you can right-click on the icon when it's running and select Options->Show in Finder to find out its new location and drag its icon to the permanent entries in your dock.
    Hope this helps; worked for me.

  • IMac 27 screen went blank installing snow leopard

    My iMac 24 screen went blank installing snow leopard. Should I wait? I wish this **** machine ha a HDD light like a PC.

    You can attempt to reset the PRAM in the machine, but it looks as though there's a hardware problem. It's actually kind of difficult to determine if it's the graphics hardware or the mainboard, but neither are really servicable. You'll want to take it to get serviced.

  • IMac 27inch screen shutoff

    hi my iMac 27inch screen shutoff automatically. Sometimes I can wake the screen up again but sometimes I can't. Sometimes the screen just turns back on after a few minutes. I sent it back to the place I bought it. They say the either the motherboard or the screen is broken. I have to pay something around 800 dollars to repair it. It almost half price of the computer. Is there any other solution to my problem? 

    Only if they are wrong about the screen or motherboard being broken.
    How old is it? And you did not get apple care when you bought it?
    Had you gone to system preferences>energy saver and adjust the time before the screen sleeps?
    The "turns back on" kind of is a bad sign for you though... Sorry I am unable to help at ALL.

    Hi Brett L,
    thank you for the coordination of this helpful thread. Are you Apple? If yes, please allow me to ask you three questions:
    1) The Display Firmware stopped for over 90% the flicker issue, but what has this Firmware changed exactly?
    2) Is Apple preparing a fix for the yellow tinge?
    3) When will it be save to buy a new iMac?
    Thank you for your efforts.
    Hello Citrus.
    Excellent questions.
    I hope that Apple will authorize Brett L. to provide us with some clear, honest answers to them . . . although, as I pointed out before, it would seem by the latest messages that have been posted in this thread -- that is, the *original thread* -- that through their actions, Apple has already provided us with their answer -- and solution -- to the yellow tinge issue; and that is the replacement of the LCD panel.
    As to what the most recent display firmware update did, I am doubtful that Apple will allow Brett to reveal that kind of information, but we can be hopeful.
    As far as when it will be safe to purchase a new iMac, I seriously doubt that Apple will say anything which would suggest that it is not safe to purchase a new iMac now. What company is going to say "Don't buy our product now. It's not safe"?
    For my part, I have now contacted Apple regarding the issues that I am having with my 27" iMac, and I will wait over the next few days to see how things play out. Based on the testimonies of others here, I don't expect Apple to disappoint. I have the confidence that they want to leave me a satisfied customer who will continue to purchase their products in the future.

  • IMac G5 Screen Cracked!

    My iMac G5 screen was cracked when my son threw a toy at it while throwing a fit. Some of the old background is still visible, but most of the screen is dominated by wierd colors and designs. Is it possible to get this fixed? If so, how do I go about doing it?
    iMac G5    

    Hi,
    I don't know if it is going to be cost effective for you to have your screen replaced. I've seen some posts here at the forum quoting prices in the $600+ range.
    You might want to call Apple Service, I'm sure they have a standard price for replacing display. I would try to figure out how you can back up your data. I believe you can also add a 'second monitor' but you would have to do all the configs and if your screen isn't working that's nearly impossible...

    My iMac G5 screen is blurred by black and white horizontal lines and tiny rectangles. This occured after I woke it up from sleeping. Everything else seems to be working fine, but is impossible to see what I'm doing. Any ideas on how to fix this?

    Fixed it! Rebooting the computer while holding down the command, option, P and R keys while letting the chime ring 4 or 5 times did the trick.
