Apple iMac 24" Screen issue

Hi -

We have two 24" Glossy iMac and the displays on both have begun to show, (what I can only describe as stains) that make it appear as if there is a layer of dust them although there is not. They are streaks here and there and being a photographer it is becoming quite an issue. These streaks look like shadows and make working in photoshop frustrating. Any ideas on the why's and the how to's?

    Just a month working and first stain appairs in left corner

  • ikenefick Dec 04, 2008

    It looks like it's dust - I suspect it's more from excessive temperatures inside the case. If you load iStat or AMBIE you can check the temperatures reported by the various sensors. My power supply was showing 81oC and the upper left of the casing was extremely hot to touch. I fear the possibility of fire so I'm turning mine off when I'm not in front of it.

    Light grey streaking along the top center of the display resembles star trails. The machine is about a year old.

    I have light gray streaking resembling star trails along the top center portion of the screen. I started noticing the problem when the machine was about a year old.

    Same story as Mishko here..
    Imac 24" and stain problems FOR SURE ON THE INSIDE of the screen.
    Stains look a bit like fingerprints.

  • blackjake Apr 27, 2009

    I have the same problem and I am also a photographer. I am finding it increasingly difficult to edit as there are dark fingerprint sized patches of fog under the screen, about 3 cm in. Help!

    The problem is definitely below the glass.

You are not alone. its not that hard to clean. really you need the cloth that came with the screen...most people throw it out. and all you do is dab it with a bit of water and gently massage the screen. and it looks as good as new. if you dont still have the cloth use a very silky delicate piece of cloth. if it is underneath the screen (very unlikely) take it back to the shop you baught it for and if it is an apple store then they will most probably clean it for free. 
also do the stains look like the are on the inside or outside? and, do they move at all?
if you took a picture of your screen and posted it on here. i will be able to give you a better idea on how to.. fix ya

My imacs screen wont show up what do i do?

get an external monitor and the correct dvi adapter and plug it in to te back and turn it m Make sure that in the >System Preferences>Displays you have mirroring turned on then you should be able to a least use your mac. My sister had the same problem this solved it somewhat She hides the iMAC behind the new screen. Only other solution would be to take the iMAc in and probably have the display board replaced which would cost you more than the new screen. You will still have the new screen to put on a new computer and use it as a second display.

My 21" mid 2007 imac periodically freezes, the

Try booting it into single-user mode holding down Command(Apple) and S buttons when powering up. Then in terminal console, use chkdsk -fy. Use it and use it again until comes back with something like "Volume appears to be OK". Then use command: mount -uw / and then type reboot and try booting normally.
If it does not fix your problem, it's most likely a hardware issue (logic board / graphics card), and you should take it to an Apple Authorized Service Provider.

Smudge, streaks, rays imac 24 monitor clean inside LCD

Yep, you can clean the LCD and the inside of the glass, but you will need two suction cups for glass. The ones for picking up window glass work. Lay the computer on its back. Place the suction cups at the upper corners and pull straight away from the table. The glass is held on by magnets and may have tabs at the bottom, so once the magnets are loose you may have to lift the glass away from the bottom edge. Be careful, it isn't safety glass and can break if dropped. The hardest part is keeping dust from getting between the screen and the glass during reassembly. Try working in a dust-free environment. I use two micro-fiber cloths, one with screen cleaner and one dry. You can't believe how much static builds up on the inside of the glass. It just sucks in dust. Don't wear fleece or you'll end up with fuzz as well. Stand your iMac up to reinstall. Clean the outside of the glass so you can see any dust on the inside. Place the bottom in place first. As you prepare to move the top into place, have light behind and above you and view the glass with the black screen behind. You can see most of the dust that way. Good luck.

MY iMAC 24" won't go off the apple screen with the spinning circle. I tried unplugging it--unplugged ethernet...etc. started it holding "s" down but nothing??

Was this a restart after an update? sometimes it takes quite a while. if not boot from CD/DVD and repair permission on the drive from the utilities folder. It is the biggest issue with startups.

New imac 24inch screen does not start

Hi there,

If you have re-installed the RAM without any luck, it looks like you have to take trip to your closest Apple Repairer. It could be any number of problems. Video card, display, logic board. Only when it has been diagnosed will it be known. If the computer is less than 10 days old you can ask for a new one. Yours would be classed as DOA. If not, standard warranty it 12 months from the Invoice date.

Hope this helps
