I have a black speck under the glass of my new iMac 27", not sure if it's a dead pixel or a spec of dust. I can't stop staring at it should I take it back?:(

If it's perfectly rectangular it's a dead pixel, - if not then it's dust, which you can remove with some suction cups and a can of compressed air.

It's dust but screw that I'm not using any suction cups, I'm taking it back tomorrow.
Now to decide if I'm getting another one or getting my money back.:(

Once you realize how difficult it is to keep dust out of behind the glass in manufacturing, you'll regret taking back your otherwise perfect (?) iMac for this issue. It takes too seconds to tilt the glass out and blow a gust canned air in there. Boom. You don't even need to take your iMac off the desk to do this!
 
You'd really consider asking for your money back because of a spec of dust?

Are you serious, I just dropped 2 grand and you think I should have a black spec under my screen?
:confused:
I have a big old suction cup , how do I do this? Thanks for the help.

i feel you should just take it back and get it removed!! 2grand is not hay and you deserve a screen without a speck of dust!!I am not sure why you would want to try removing the glass panel and all....

Really? It's not difficult to remove the glass. If you feel uncomfortable doing it yourself then you could have a tech at the Apple Store do it for you. It's just a spec of dust. It's not like your screen is flickering or you're suffering from the infamous cat pee screen. Or are you? ;)
 
This thread reminds me of this other one -

which included the rather traumatic post -
Ok, so I took the glass off and whilst lifting it the iMac started slipping off the table. I rushed to grab it but in a desperate attempt to save it, I let one hand go off the glass which inevitably fell on it's corner and pierced through the LED display. Not only is there a giant dent on my LED display, it seems to have pierced through and damaged the hard drive, and also the processor seems to have being dented.

Did someone say easy?

Here's a link on how to do it without drama -

Hope this all helps.
 
Of course he should feel uncomfortable with putting hands on a BRAND new and under guaranty iMac.

If its that hard to keep the screen clean of dust in a production hall (which surley is a cleanroom) its nearly impossible to keep it clean on your desk. Dont be a fool. - Let it do the Apple guys and demand a cup of coffee for your patience.

(For sure one can do it on his own, BUT why should one risk the guaranty for just a piece of dust)

I don't think he was saying you should live with it, he was questioning why you would get a refund rather than just exchange it. What would be the point in getting a refund?
 
So I took it to Apple and they offered to fix it, I said sure, ten minutes later they came back and said they had an issue while removing the screen. They offered me a new one and I said sure but I didn't have time to look at it in the store. I got home and it had another dirt spot! Now I have to go back Thursday after work. I'll have no computer for another day. I'd go tonight but it's my birthday and I have things to do.
I won't leave the store before checking it out this time. At least the aplle folks were nice I'll update Thursday.



Posted from my iPhone so sorry if spelling issues.

Jesus!!! did they just drop it while removing the glass?? what a bunche of butterfingers, did you asked what happened?

but then again what are the odds, when giving a new one it has the same dirt spot....is it in the same place the other?
 
Different bigger spot on the new one. I'll be more patient this time because I am clearing my schedule to deal with it. So far Apple has been cool, should be an interesting day.
 
I think if you look closely most iMacs probably have some dust ingress. Mine did (along with other faults), so it went back for a refund.

The manufacturing process shouldn't allow dust to get in.
 
No it shouldn't!!! I'm giving them one shot tomorrow, if it isn't meant it isn't meant!

There's no such thing as "isn't meant." yes dust is unfortunate and can be annoying, but it's fixed SO EASILY. I fixed a speck of dust without even moving the iMac/turning it off. You just hold the aluminum while pulling on the corners with the suction cups. You don't even need to even remove the glass completely. Just tilt it forward from the top and blow a bit of air in there. Boom, problem fixed.

Assuming you've actually blown the dust out and not forced it into a recess only for it fall out again at a later date.

What happens if the glass cracks during this process? Will Apple kindly repair it free of charge?
 
Last night at the Apple store was fun, at first some manager gave me crap for returning my second one. A cool genius came over and told him that I had a dead pixel and to return the computer. We started the 3rd one up in the store and it looked fine. So far so good, the genius offered me a free keyboard with number pad since it was my 4th time in the store this week. I don't really love the keyboard but it was a very generous offer.
I really hope this computer works out, I love it so far. I do wish I NEVER read anything about yellow screens though, I'm constantly trying to determine if my screen is slightly yellow or not.:)

Hopefully I finally have a good iMac. Thanks for all the input.

good luck with the (finally) good machine :p it was about time
 
these production lines are in clean rooms the people there even have to wear hairnets and beardnets and some overshoes to avoid any dust, at least thats how things had been done when i worked for siemens nixdorf
so dust can only appear if someone does not follow the rules , consequence
he should get a bollocking and his supervisor ,who is responsible to watch what is going on should get one too as all these return iMacs because of dust even when it can be removed in the shop cost apple money,
poor apple we should start to make donations so they can carry on dusting iMacs
