IMac 27" Strange Screen Marks Behind Glass

Hi
I've had my 27" iMac since march this year, yesterday I noticed that there is a strange yellow/brown blotchy patch in the top right hand corner, it is not on the front of the glass (it cant be wiped off) its on the INSIDE! I tried to take some pic's but my camera is useless and it looked like it was picking up a lot of light interference from the display itself.
Anyway I have done some reading into this and a common thing that came up was smoke, well I don't smoke so it's not that. I don't have Apple Care but its still under the first year of warranty, and I don't have the balls to take the glass off and clean it.
Has this happened to anyone else? And is it covered under the first year of warranty?
Regards
Marky

Take it in. They will give you a new screen, as they did for me for my 24" about 6 months ago and will have to do for my husband's 27" iMac, since his has developed this issue too. Behind the screen shows lines that look like long lines of dripping dust.
My machine has now developed a sound issue - no sound out when I plug in the external speakers. I will take it in to get that fixed. They have already replaced the motherboard once for a spontaneous shutdown issue it was having. And my husband's will suddenly not read data DVDs - could not install Aperture. Don;t know if he can boot from the DVD now.
I mention all this to tell you that, while inconvenient to take it to Apple and wait for them to fix it, while it is covered you should always go that route for the "hmmmm?" stuff. They'll fix it, most like;y with new parts.
And to get the best coverage for the longest amount of time, buy Apple Care, if you have not done so already. This has saved us many, many times over the years and all our machines. We always buy it. We don't always need to use it but when we do need to, it is GREAT to be able to just call them up and ask questions. Or just take in a sick machine and have them fix it.
You have to buy Apple Care and register it to your machine BEFORE the year of support you got when you bought your iMac runs out. You cannot buy it and use it after that 1st year is up; it must be purchased and registered to your machine before that 1st year is over. Apple Care will add 2 years of support for your machine. It has been worth it for us. Phone support, hardware support.

  • 24" iMac screen mist behind glass

    For a couple of months now my 24" iMac screen keep misting up behind the glass around 30 mins after booting - anyone know a resolution for this? Will Apple replace the screen even though i've had it around 4/5 years now?

    It is common to get condensation between the display and front glass panel, if it is humidity and cool in your office or home.
    A few things that you might try, are
    1. Reduce the level humidity with a dehumidifier.
    2. Leave the iMac on longer until the condensation dissipates.
    3. Remove the front panel yourself and clean between the display and glass.
    Will Apple replace the screen even though i've had it around 4/5 years now?
    No, but if you contact your local Apple Store or AASP you can schedule an appointment to have it dried and cleaned.

  • Grey smokey marks behind glass on 27" iMac

    Does anyone know what this is, what causes it, and if it is covered under the 1 year warranty? It is getting worse and it is extremely annoying for doing any kind of graphics or design work.
    http://imgur.com/a/oPM3m
    It's right in the middle/right of my screen and definitely under the glass; I tried using a dry cloth to clean the screen but it did not help.
    Anyone familiar with this issue?
    Thanks

    Before you assume it's the TFT screen, it could be just the iMac's protective glass that's cuasing this issue.
    This maybe the dirt and smoke culprit
    If it's not under AppleCare and you want to save a few bucks in repair costs, the iMac's glass can be removed for cleaning. You need to power down the iMac prior to doing and unplug prior to doing this.
    The glass is held on by strong magnets as the back of the iMac's glass uses a metal framework on the back of the glass and can be removed with a little care.
    There are two ways to do this.
    You can use a thin flat stiff knife putty knife of rigid plastic to pry one of the top corner of the glass away from the iMac's metal frame while holding onto the whole corner of the iMac. Then just use your hands to pry if from the magnets all the way across from the top and then as you proceed down toward the bottom pull toward you to loosen the bottom then lift off. There maybe twosmall  locating pins inthe frame you need to be careful to not lose. They should come out with the frame.
    Or you can use two small suction cups to remove the glass. You can use suction cups like the ones you find for hanging plant planters on a glass window of for hanging something on a glass window.
    Here is an online procedure for removing the glass here.

    or
    http://www.youtube.com/watch?v=9cHMHzq5E5I
    or
    http://www.youtube.com/watch?v=yeAZqw-494Q&feature=related
    Once removed you can repower your iMac to see if the issue went away. If it did, you know it's the glass scren that's dirty and not the TFT screen.
    The protective glass can be cleaned with an amonia free glass cleaner with a microfiber cloth or with something like iKlear screen cleaner with a microfiber cloth or even a micro fibercloth wrung out well in warm water. Clean it laying the glass on something protective like a large terry towel to prevent any damage.Then power down your iMac and carefully replace the screen making sure to put the locating pins back into the metal frame, if they fell out, using the suction cups to hold it while slowly and gently putting it back in place until the glass is caught be the magnets

  • Strange greyed mark on screen?

    Hi,
    I have just noticed a strange grey mark on my screen (I think it is similar to the ghost mark questions some people have posted).
    It only shows up when the screen has a dark colour on it, but is only visible with the backlight on, and seems to disappear when I dim the brightness al the way down, see pics:

  • Keeping Thunderbolt Display Free of Smudges/Dust Behind Glass

    Hello,
    My brother has an iMac and he's told me about an issue with air quality and the accumulation of dust/smudges behind the screen glass. From reading the manual that came with my Thunderbolt display I understand that this can be an issue for it as well.
    I am in the city, in a high air pollution area. There is a lot of dust. I'd like to prevent this issue before it becomes a problem. Keeping the area surounding the display dust free is obvious but I'm still worried about it. I did not buy this display so it could have smudges behind glass in 2 years.
    I think an air filter would be best. Something that is low profile. Anyone know of such a product or has something like this in place?

    Hi Clinton,
    Thanks for the idea. I have been researching airfilters.. notably smaller desktop airfilters. I read on one of the other forums that the display issue concerns microscopic dust so I'm going to go for a HEPA type air filter, the types people with allergies use.
    Incidentally I found one that runs off a the mac USB connector (not that it was on my wish list) but its small and doesn't look bad either. My only reservation is it is sold by a company I'm not familiar with. I can't find the manufacturer and so getting replacement filters down the road may be an issue.

    Thanks again for your help.
    Best regards

  • Strange lines appearing behind itunes

    I went away for the holidays, and when I got back I booted up my 2006 iMac. Today for the first time, there are strange lines appearing behind iTunes whenever it is open but not the active window. I tried quitting and restarting iTunes, but the lines come back. I wish I could upload a screen shot of what this looks like on my desktop, it's very weird. It does not happen behind any other program window. Only iTunes. The lines appear as if they are extensions of the iTunes window formatting, in line with the side bars, etc. Has anyone else experienced this? Any tips for getting it to quit?

    I just wanted to add that I am also seeing the same problem: strange lines around the borders of the iTunes window. The most obvious ones are a set of four vertical lines running parallel to both sides of the iTunes window, although there are other strange bits as well, mostly around the top corners of the window, as well as a single thin horizontal line above the top of the iTunes window. These unusual lines started appearing "out of the blue" sometime in the past few weeks -- as in, not right after an update or any other configuration change to my mac... The only change I can say I did recently was to update to OS 10.6.6, although I know others who are running 10.6.6 and aren't having this issue with iTunes. I also wanted to add that in my case, I only see these strange lines when iTunes is the active window. Further to that, updating to iTunes 10.1.2 does not fix the problem, unfortunately.

  • Strange screen display

    Strange screen and system freezes overnight - new iMac 27" with Lion
    Twice now have found the following on screen in morning. System  also unresponsive when this happens and requires powering down and restarting. Otherwise system working fine.
    These are two pics of same screen taken with a camera (first one showing room reflection)
    Anyone have any idea of what this is?
    Tks,

    It looks like you have a faulty USB device, probably a hard drive, which might account for some of your issues, but it doesn't explain the display.
    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
    Below are several lines of text in monospaced type, which are UNIX shell commands. They’re harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of running these commands, search this site for other discussions in which they’ve been used without any report of ill effects.
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
    To begin, launch the Terminal application; e.g., by entering the first few letters of its name in a Spotlight search. A text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” (without the quotes) and press return. You should then get a new line ending in a dollar sign.
    Step 1
    Copy or drag -- do not type -- the line below into the Terminal window, then press return:
    kextstat -kl | awk '!/com\.apple/ {print $6 $7}'
    Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
    Step 2
    Repeat with this line:
    sudo launchctl list | sed 1d | awk '!/0x|com\.apple/ {print $3}'
    This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple/ {print $3}'
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Sta}* L*/Fonts 2> /dev/null
    Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, change it to something like “[email protected]” before posting.
    Step 5
    osascript -e 'tell application "System Events" to get the name of every login item'
    Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
    You can then quit Terminal.

  • IMac G5 strange startup beep

    My iMac locked up when waking from sleep, so I restarted it. I got a strange multiple note beep that repeated three times. It began to startup and then I got the folder with a flashing ?. I booted from the OSX disk and used disk utility, but my hard drive doesn't show up. Is my drive dead or is there something else I can try?
    iMac G5 20" screen   Mac OS X (10.4.8)  

    I am having a similar issue with my parrent's iMac G5, however, instead of 3 chimes, im getting 3 strong buzzing sounds.
    I also assumed it was the drive, and in fact after starting up from the 10.4 installation DVD, Disk Utility would not list the drive as a volume. I replaced the drive with another SATA drive, and still Disk Utility shows now drive available other than the DVD drive.
    Ive never heard these buzzing sounds before. I was told that for several weeks before the startup problem occured, the fans were constantly running at full speed.
    Im going to try to reset the SMU and OF today and see if that helps. Unfortunately, AppleCare was not purchased, so it is out of warranty. Any info would be greatly appreciated.

  • Hairline crack in touch screen (not the glass) in Xperia Z1

    I have a 5 month old Xperia Z1 mobile phone which has never been dropped or knocked.  On removing it from a padded pocket in my bag I noticed that the touch screen under the glass has a diagonal hairline crack originating from the top centre of the phone to under the right hand corner (the external glass has no crack).  After researching this I note that this is a known fault with the Xperia series mobile phones.   http://www.xperiablog.net/2014/05/30/bbcs-watchdog-investigates-xperia-z1-cracking-screen-issue-sony...
    I have not been able to contact Sony for advice using their contact us email form (dead link), live chat (not currently operating), or by phone (busy signal whenever I call).
    I am really dissatisfied with my phone cracking like this particularly when it is not the result of negligence.  Can you please respond to my query and restore my faith in your customer service...

  • IMAC ergonomics and screen viewing strain

    I have been using my 24" iMAC for a couple of years now and from the very first moment had difficulties in viewing such a large, but wonderful, screen. Using my normal working desk and chair, I had to really tilt mu head upwards to be able to see the whole screen with my glasses. It would have been easier, I thought, it the screen could be lowered with respect to the stand it was fixed to. But this being practically impossible, I made a whole in the table surface to let the stand go through it and fixed a shelf to support the stand. So now, the bottom screen edge lies almost touching my desk surface and with the help of a taller stool, I find it easier to view he screen now. But this is a "patch" to the solution and I was wondering if any of you guys had the same problem and if you got round it in a different and more efficient way. Do the make any accessories to replace that stand? Any ideas?

    You can remove the stand, if it's a 24-inch Intel iMac, attach a VESA adapter, and connect it to some type of articulating arm that can be positioned more flexibly. This is the VESA adapter for the aluminum iMacs (24-inch only)

    The adapter for the older white iMacs is different, and no longer seems to be available, at least at the Apple Store.

  • IMac 24" Replacement screen has deep scratches

    i recently had a problem with my 24" iMac 8,1 that the screen had major burn-in and blotches and horizontal lines everywhere. i took it to the apple store and they replaced that along with my hard drive. i received my iMac back and everything was great "so i thought" today the sun was shining on the iMac and the screen was turned off and i could see a whole bunch of marks and scratches in the replacement lcd itself and very deep ones to the right of the screen. this is not right it seems like they dont take any effort or care in replacing the screens of computers.

    its probably just a factory mistsake. not to get off topic but Nintendo has things like that too and sometimes worse. just tell them that when u had it replaced last time, u got it back with scrathes and nick theyll probably replace it. then inspect it again. if the same thing happens or they decline demand a new unit

  • Which Airport card do I need for an iMac G4 Flat Screen 15"?

    Hi, I have an iMac G4 (flat screen, with silver arm and round base), 15".
    I'd be extremely grateful if someone could let me know which Airport card I need for this Mac and also whether or not I also require an adaptor. I have looked this up on the Apple site and also in 'The Flatscreen iMac for Dummies' book (I'm a complete technophobe, I'm afraid!), but am none the wiser.
    If possible, model numbers for the Airport card and adaptor that I do need would be much appreciated.
    Many thanks,
    Jeremy

    Choose About this Mac from the Apple menu and click on More Info, or if you're running Mac OS 9, choose Apple System Profiler from the Apple menu. Check the speed of the computer's CPU; if it is below 1GHz, you need the regular AirPort card, with the AirPort Extreme card being used on newer iMacs. No iMac G4 requires an adaptor to use an AirPort card.

  • Is iPad Mini with Retina display screen a gorilla glass?

    Is iPad Mini with Retina display screen a gorilla glass?

    No it's definitely not gorilla glass... I don't know if it's even hardened glass. My iPad Mini's screen broke the other day with the slightest bump. When I submitted it to Apple to be fixed (I assumed it was weakened in production or something) they said it would cost $225 to replace it. So yeah, be very very very careful with your iPads... don't let your kids touch them or anything (buy them Kindle Fires). I'm going to attempt to fix my iPad Mini's screen myself (lest I cut myself). If that doesn't work I guess I'll have to move on to Android tablets with gorilla glass...

    Is there any hopes for a device/adapter that would make it possible to use an Thunderbolt-equipped iMac as a screen for other devices? It worked with DisplayPort, why wouldn't it work with Thunderbolt? Is it just a business political decision?
