Dead pixels on 2011 iMac?

Hey everyone, I have a mid 2011 iMac 21.5 with an i7 processor. For the most part it's worked great for me but recently I started noticing what looks like dead pixels on my screen after start ups and coming out of sleep mode. I took a picture of my desktop so you can see what I mean:
They seem to go away once the screen has warmed back up but you can see why this would be so frustrating for me on a new computer that I expected to run smoothly. Anyone have any ideas what could be going on?

I have no idea what would cause this but you should be within warranty. I would take this straight back to apple for repair/replacement. Either a faulty graphics card or display unit either way it should definitely be covered by the one year warranty.
Good luck

Third replacement... more dead pixels (27" i7 iMac)

I'm so sad... we just unboxed a new iMac after waiting a month for the last dud to be replaced, and there is a pair of black, dead pixels near the middle of the screen.
I really hoped this one would not have any obvious defects.

Ask for a refund and hope Apple can get it right soon.

Apple dead pixel policy

Does anyone know apples policy on dead pixels? Is the same policy as most of the companys out there that say the screen is not faulty unless it has a certain number of dead pixels. I have a dead pixel on my imac g5 17" which stays black all the time. I think it is outrageous that a company can say the screen is not faulty. I think i am going to ditch the imac g5, buy a power mac then buy a samsung screen to go with, apparantley there do a zero, yes zero pixel policy. Any more than zero dead pixels on samsung screens are classed as faulty. Thanks a bunch apple now i have an imac i dont even want to look at.

Excuse me? There is no need for that tone.
I got my info from Samsung here and if they haven't updated their site to reflect the new policy, then that is not my fault. Furthermore, if they can't update their site to reflect this policy, I doubt that they will stand behind it. If I had a "no-defect" policy, I would be sure to have it plastered all over my site.
I stick to my opinion that a single dead pixel is acceptable. If perfection is the only thing that you will accept, then you can prepare yourself for a lifetime of dissappointment and ensuing therapy.

Dead pixels on the 24"?

is it me or is anyone else detecting a trend with dead pixels on the imac 24" models? there seem to be a few other posts here about it. i unfortunately had to ship mine back to apple last week because it had around 5 dead pixels (black) clustered together on the right middle area of the lcd. i ordered a custom config (upgraded to geforce 7600) through the apple store online. i had the wind taken out of my sails when i first booted up and realized that they were dead.

Just in case there is confusion over this matter, a dead pixel and a stuck pixel are two different states. A dead pixel is not repairable. It indicates that the transistor at that pixel position is inoperative. A stuck pixel indicates the pixel is fixed at a particular "on" state and can sometimes be forced to another state through the various techniques others have already mentioned here and in other threads. A dead pixel appears to be a pinpoint of white light (I have one on my new 24") and can only be repaired with a display replacement. Since there is always the possibility of damaging an LCD display when forcefully rubbing, I wanted to make sure folks understood the difference. If the pixel is dead, no need for attempting repair.

IMac screen gains dead pixels from Mac Store visit???

My 3.4gHz i7 2011 27" iMac died, so I brought it into "The Mac Store" here in Portland (an authorized Apple reseller and repair facility). According to the work order, they changed out the logic board and the video card under warranty. When I picked it up last week, I noticed there was now a spot of 4-8 stuck dark pixels (all next to eachother in one big splotch) on the LCD that wasn't there when I dropped it off. I opened it up to put my hard drive back in and I saw that the SMT connector on the top of the video card (ambient light sensor?) was damaged, the plastic was broken and the plug was hanging on by gravity, not plastic tabs. So it still works, but the cable could pop off on it's own.
My assessment is careless work. The LCD was either swapped for a different unit, or damaged by the repair techs. Is it possible that a LCD can be damaged in a way that it receives a spot of dead pixels? AFAIK thats a sign of bad transistors and more of a manufacturing defect, which leads me to suspect the LCD was swapped out. The pixels are next to eachother both vertically and horizontally, so I'd doubt it's a video card issue.
The way the video card is damaged shows me they were careless during installation of the new card, and either didn't notice it (doubtful) or figured I'd never notice so they left it. Just speculation on my part, but as someone who does IT consulting for a living myself, it seems really sloppy either way.
I emailed the customer service address twice (in response to my work ticket) and the local store manager once, but have not received a reply or acknowledgement. I had to reschedule a second appointment and go in on my own. When I did the, the guy who received my iMac at the service desk said while it is not his call, he doubts they will fix it as "Apple has a policy regarding a certain number of allowable dead pixels", which completely neglects the fact that my LCD was perfect when I brought in the machine for unrelated service. He also said that the fact that I noticed the bad video card connector shows I was opening up the computer to reach non user servicable parts and therefore they probably wouldn't cover that. Which is ridiculous to me for a couple reasons, first, the Apple Warranty terms of service say nothing about voiding warranty for changing out the hard drive, second, it's illegal to void a warranty if I didn't damage the unit while servicing a user servicable part, and third, that gives them a self defining ability to damage anything inside my computer and then if I notice it they use the fact that I noticed it as a way to get out of fixing it. Kind of a catch-22 if you ask me.
So I'll be posting my follow ups to what happens here, but in the meantime, my questions -
- Can a LCD gain bad pixels from careless handling? Can a splotch of bad pixels be related to a bad video card?
- Has anyone had service like this from Mac Store or Apple before? I paid a lot of cash for this system and this is pretty frustrating.
regards,
Rob

Follow up post - I brought the system back, they were really nice, the escalated it, I got it back in 2 days, they must have had to overnight some stuff for that, and probably ate the costs themselves. The replacement LCD is perfect, the backlight board was swapped, everything is good, and they were nice to deal with the whole time.
I should have given them a chance before posting here. They went out of their way to treat me well, and that is appreciated. Please ignore the frustrated tone from my first post, it was just grumpiness on my part. Crap happens, customer service is how that crap is dealt with, and they did a very good job.

IMac late 2010 has dead pixels. What are my options?

I bought a 27" iMac Sept. 2010 and in May 2011 I noticed some dead pixels on the bottom left had of my screen. To be honest I'm a little heart broken by this because if I decided to sell it today, I wouldn't get the natural depreciated value because of these dead pixels. I know I wouldn't buy a computer with dead pixels. I do have apple care so I'd like to know what my options are.

AppleCare's Express Lane. Do note that if you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine..

Second 27" iMac with dead pixels

I'm intrigued to see how many others have purchased the new 27" iMac's and have managed to get one without any dead pixels.
I am currently on my 2nd 27" iMac and both of them have a dead pixel right in the middle of the screen, first one was black, this second one is red.

btw, is there any dead pixel policy?
It's a fault just like any other type of fault. Your brand new iMac's pixels are all meant to be working. If you receive one where they clearly are not you are right to have it replaced. This is not a PC, it is a top of the range Apple product for which we expect and demand the highest quality. After all, we're paying top dollar (or £) for this level of build and design. Accept nothing less.
Actually, Apple considers one dead pixel 'within spec'.
However, if you've only just bought it, you can choose to return it for any reason within 14 days.

24" iMac Thin darker line on the screen - dead pixels ?

I have a 24" BTO iMac with 3,06 and GE Force 8800 GS, delivered last year in June.
Was very happy until today, when i remarked, at +/- 7 cms from the right edge, a thin line, extending from top to bottom, and seeming to expand a bit in a blurry way in the middle.
It shows much more in when on a dark background.
Could that be dead pixels ?
I guess I have to ship the machine back to an ARC ?
Or is there some test I could try first ?

A screenshot would not including any effect from a physical screen defect. For the computer, the pixels are there and working properly.
If it appears to be blurry, it may be something casting a shadow between the LCD and the backlighting. Dead pixels are distinct, so there should not be a blur between where the pixels are working and where they are not working.
In any case, since the Mac is still covered by the one-year warranty, you should probably have it looked at by an Apple authorized repair place

Dead pixel in 17 inch iMac.

I just got my iMac G5 yesterday, and it really is the greatest computer ever, but I noticed that there's a dead pixel on my otherwise perfect screen. It's an extremely small white dot (smaller than a grain of salt), which is hardly noticeable, but it still bothers me when I do see it. It's borderline nitpicking, but I did pay good money for this thing. Does my warranty cover this?

At the Apple Store here in Las Vegas, I was looking at discounted iMacs a while back. G4s. They had two for a decent discount. One was a demo model, the other one was a return with 1 dead pixel. Otherwise, it was brand new. They were willing to sell it for $200 less, but after two weeks no one was buying. I asked what happened, if the original purchaser got a new one, and the rep told me they replaced the whole computer for free (he was the rep that did the transaction). He also told me the guy was there for about two hours filling out paperwork. Also, the whole thing had transpired three weeks before I was there, and they still hadn't sold the computer, just because of that one dead pixel.
The dead pixel was a red one in the bottom-right corner, about two inches from the side and one inch from the bottom.
I guess the guy was lucky?

2nd iMac with dead pixels

Just curious if anyone else is having dead pixels (non-functional pixels, black) problems with their new iMacs. I own 4 LCDs and use two more at work and I don't have this problem with those displays. I am a web developer and graphic designer so I am a little picky when it comes to displays, but I just bought this iMac (11-30-07) and it is the second one (returned the first one) to have defective pixels. The first had a dead pixel in the top left area (right where I work in PSD), and the second has four scattered in the bottom area, and they seem to be popping up with regularity. The easiest fix is to buy a second high quality display and just use this iMac as a dual monitor setup . . . but then with that thinking, why didn't I just buy the Mac Pro? All-in-all, this is still a pretty decent machine. . . .

I to have recently purchased a 20" Intel Based iMac at my local Apple Store, after booting the beautiful computer up i noticed two small pixels where black. I plan on returning the computer to the Apple Store and getting a brand new one. And i know that a couple of pixels is tiny and nearly noticeable unless you look for it, then when you find it the thing just screams out at you, but considering the prices Apple charges i expect nothing but a perfect product and so should you.

IMac G5 dead pixels?

Hi everyone!
I've never posted a question before so I'll make it short and sweet. Basically my iMac G5 I purchased in May 2007 has a 2 1/2 inch vertical white line on the right side. I tried calling Apple Support and since I don't have Apple Protection I have to pay to speak to someone which is fine, but I know that is a common problem and if the answer is you're out of luck I don't want to pay additional money when I could use that money towards a new computer. I could also go up to the Mac store but from reading different blogs/threads unless I'm covered under the LCD pixel abnormality I'll just end up spending more money to not get it fixed. Any suggestions, updates, restores anyone would suggest or am I better off selling my iMac as is and getting a protection plan for my next Mac purchase? Thank you so much!

Excuse me? There is no need for that tone.
I got my info from Samsung here and if they haven't updated their site to reflect the new policy, then that is not my fault. Furthermore, if they can't update their site to reflect this policy, I doubt that they will stand behind it. If I had a "no-defect" policy, I would be sure to have it plastered all over my site.

New 2.4GHz Imac Dead Pixels

I know dead pixels are always an issue. I purchased a PSP and went through the dead pixel exchange over 12 times. I was lucky to get an iphone with no dead pixels, but now I decided to get my first mac. Since the new iMAC came out I decided to get one. I was going to get the mac mini, but when I saw the imac and the power you get for the price I was hooked.
Anyway I believe I have a defective screen and I think it is just going to get worse. At first the screen did not have any dead pixels, but after about 3 hours of use the first day I noticed a subpixel suddenly was now black. It looks like it is the green subpixel since that is the only color it cannot display. So I said to myself okay I can deal with one dead subpixel since it is on the dock and just placed photo booth over it and I couldn't see it and would be happy with it. Ignorance is bliss. But now the second day I was using the imac and then suddenly 4 more black pixels came near the top left area of the imac. So that is 5 dead pixels now it two days.
Has anybody had good experiences with returning their mac with dead pixels on their screen? I hoping 5 or more dead pixels is enough, but wanted to get a feel from the forums if I will be just wasting my time or if there is good chance they will replace my imac. Of course I am worried once I return it I will be going through this 12 times like I did with the PSP. Any thoughts?

Okay I guess the last 4 were not dead, but stuck because I was showing my fiance the dead pixels and I showed her the one on the dock, which is still black, and then I showed her the 4 at the top left. So we decided to scroll through the desktop wallpaper (I had the default blue wallpaper on when the dead pixels appeared) and suddenly the 4 at the top left area disappeared once I went back to the default blue wallpaper. Not sure if they are going to show up again, but as of right now they are not there anymore. I hope they are gone for good. Maybe I wil get lucky and eventually the one at the bottom on the dock will light up again. I will keep my fingers crossed. So I guess a suggestion to those who may experience what I just did, try chaning your wallpaper and see if that makes the pixels come back and if that doesn't work then you can try those popular pixel fixers.
I will update if more dead or stuck pixels appear or the others come back. I am now not sure if my screen is considered defective or just a late bloomer. I don't want to be a complainer I just want higher standards when it comes to QOS.

Dead Pixels on brand new 24" iMac

I picked up my 24" 2.8GHz, 1GB Ram, 320GB HDD iMac on Friday the 22/02/08, and the first thing I noticed was a few dead pixels. There is a green one in the top left, one in the middle/right top and what seems like a clump of about 2 or 3 in the middle of the screen. I am very annoyed, I paid alot of extra money for a 'Premium Mac.' I will not settle for just letting this go.
So, what is the warranty/general rule for pixels?
Will they replace it gladly? Or say there isn't enough missing pixels?
This is a brand new fresh out of the box Mac. If they refuse to replace it I will just return it because I'm not satisfied with the quality.
Is there a time period in which I can return an iMac because I don't think it is good quality?
P.S. I love my iMac! But seeing it with such a defection is breaking my heart, this is my baby!!!
P.P.S I'm in Australia
Thanks for any help!

The policy on pixels varies from manufacturer to manufacturer but one thing is consistent: none of which I am aware have a zero defect rule. Most companies look at three different factors: location, clustering, and number. A couple dead pixels clusters in the middle of the screen tends to be regarded as more serious then a couple dead pixels clustered on the edge. A moderate number of pixels scattered about the screen is considered less serious still. All you can do is 1) first deal with the local dealer and if that fails, 2) try dealing with corporate.
BTW, if you do a search on fix dead pixels, dead pixels, and dead lcd pixels, you'll find there are a lot of programs that claim to do just that. In general, I've seen more success with stuck pixels being fixed (they are always on) rather than unlit pixels, but I've even seen them revived on occasion through the use of these programs.

New iMAC 27" dead pixels

i got delivery of my first mac, iMac 27" high spec machine and it had three dead pixels.. one phone call to apple and ivw got to say, there service is second to none.. straight away they arranged a second one to be made and delivered, and the first one picked up. i got my second iMAC within two weeks of the phone call.
then the second one had specs of dust under the glass!!! Again, exceptional after sales and im sitting here waiting for my third iMAC to be delivered..
half of me thinking am i being too fussy, but for the £2500 ive spent i expect perfection and apple agree.
anyone who has these issues, if your patient like me, apple have made my problems simply stress free, and im praying the third one is perfect..
my question.. am i being to fussy? three dead pixels , then dust under glass... i mainly do photographic tweaking on the imac so i hope you dont think so??

hi mark wania, i dont think you are fussy. you have the right to ask for replacement because you pay everything for it. i dont see anything wrong. i have similar problem with dead pixels.
do you know how much i have to spend for an iMac in Malaysia? you times the figure with 3.6. and that is about a month salary for a regular executive.
i have spoke to JUDE on this issue. it is TOTALLY UNACCEPTABLE that apple support set a number of tolerable defect to them. they mentioned about at least 11 pixels to enable me to get a replacement. I am talking about product defect. it does not matter to me whether it is 11 pixels, 100 pixels or even 1. I pay for the price and I am expecting a good product and kind service.
to me, apple should addressed this manufacturing or delivery issue properly.
I have done what the support team asked me to do yesterday and it seems that this is nothing to do with software, drivers or even operating system. I am going to call for a replacement or repair tomorrow as i need to check other thing as well like iSight camera. it sounds like more and more people having defect items. those comments make me feels bad that I might have chosen the wrong computer manufacturer.
