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.

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

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.

Will they replace for a single dead pixel????

My new macbook pro is beautiful. I would have to say it is one of the nicest laptops I have ever owned. I have two real complaints and one minor. Almost smack dab in the middle of the gorgeous display is a solitary dead pixel. At first I thought I could live with it but it has been two days and I unfortunately cannot. I am afraid that apple will not allow an exchange for this though, so I was wondering if anyone else has had a similar problem.
The other complaint of note is of the very nice glass trackpad. While I really enjoy using it, mine is canted from flush on the left to a noticeable lower attitude on the right side. While this is something that I can live with, I just feel like when you drop $3000.00 on a laptop it is not to much to expect perfection in the product. This I doubt would be repaired and is a bit nicpickie.
The other complaint is one that has already been posted about the screens hinge tension. I would have not noticed until I tried some alternate positions, such as in bed.
If anyone could offer any advice or is experiencing similar problems please post. I am fairly new to apple products and am curious if it is even worth my time to call and try to find a solution.
Thank you in advance.

I believe you need to have 5 or more dead pixels to quality for a replacement. If you're not happy though, call Apple and ask for Customer Relations (bypass support). They will take care of you.
For other people that want to check their screens for dead pixels, use PIXel Checker.

Dead pixel- BlacBook

I just got a new black macbook- Yesterday I noticed there was one dead pixel in the upper left of the screen. I first thought it was my desktop picture- but then changed it and sure enough it's still there.
Later on in the day- I got sidetracked, and back to work- I noticed the display is fine- no more dead pixel?
Is this something that can come and go? or am I insane and there was no dead pixel to begin with? I'd like to take care of this right away if it's something that going to be recurring.
Thanks!

Most manufacturers have a policy where three dead/hot pixels are enough to get a replacement, Apple decide on a case-to case basis. I understand however that more than one is required to get a replacement.
On the other hand, you have a 14-day money back guarantee (atleast when shopping online). But atleast I would feel like abusing that guarantee if I were to return one product just to buy the exact one straight after.

Dead pixel on MacBook Pro?

I'm getting really upset about this. I bought a 13" MacBook Pro w/ Retina about three or four months ago. Now I have dead pixels. The guiness at the Apple Store informed me that one or two dead pixels was within the quality control standards. He then proceeded to let me know that he could replace my screen, but there may or may not be more dead pixels on that screen and eventually they would cut me off because it meets Apple's "standards."
So I guess I actually have a few questions:
Is this a problem with all Mac displays? Or is this specific to the Retina display?
Should I get it fixed now, or wait for more and more pixels to die?
Are there any "at home" remedies? (Other than massaging the screen, because I already tried that)
I know Apple will replace products, but would they let me exchange it for a Pro without Retina if this is a retina specific problem?
This may all sound petty, but this computer was extremely expensive and I'm really not happy about this issue.

1) All displays. Retina display is no different in terms of composition, it simply has a higher pixel density. It is still an LCD display. Perhaps the fact that more pixels are being crammed into the same surface area would raise the probability of a pixel failure. But, it would be safe to say, no.
2) Now. This is an anomoly, not a major issue. There would be no advantage in my opinion to wait. See below for Apple's 'standards' regarding dead pixels.
3) Not applicable / No. Apple's warranty only covers your model. There is no exchange program. They will service your display free of charge within the one year warranty period. During this period, you can opt at any time for an extended warranty (Applecare), which would extend hardware coverage for two subsequent years.
4) Not petty, extremely legitimate. Expensive machine that should work as intended. This is why Apple's warranty coverage is more extensive than any other major CPU manufacturor. You are paying for a top of the line product, and the servicing needs to be commensurate with the price.

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.

3 Day Old Macbook Pro. Dead pixel.

I just got a MBP and it has a dead pixel near the bottom and bit off center to the left. I´ve tried just about every thing to fix it, but nothing.
I called the place we bought it, and the stupid Apple policy can only replace it if it has 5 or more dead pixels. There is literally nothing I can do? It´s the most annoying thing ever. I shouldn`t have to pay thousands of dollars to have a fault screen, even if it is just one single pixel.

hard to say, it depends on the product and how much it cost.
If this happened to me again, and was a less expensive computer, I likely wouldn't care as much. It'd still bug the heck outta me, but I'd be able to learn to deal with it.
For what macs cost, I don't have any qualms or any guilt about expecting things to be pretty much perfect. I understand there will be things slightly wrong here and there due to mass production, but when its something glaringly obvious like a stuck/dead pixel, that's where I draw the line.
And besides, there is no publicly stated rule that says it has to be 5 dead/stuck pixels before a replacement/refund. I know Apple has that knowledge base article on stuck/dead pixels, but last I checked, it didn't stipulate any rules when trying to exchange/return a computer for dead pixels.
I can't say I agree with your statement about how few LCDs are perfect. Out of the entire time I've purchased electronics, I've only encountered just 2 instances of a stuck pixel. Perhaps I've just been lucky, I don't know, but I'm seriously not kidding.
Lastly at this point, it seems absurd to still think that stuck/dead pixels are acceptable due to cost. While this might have been the case a few years ago, if cost is the big reason as to why we're supposed to accept dead/stuck pixels, how is it possible that companies like Dell can offer a guarantee on no stuck/dead pixels for their LCDs?

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.

ONE DEAD PIXEL ACCEPTABLE?

i have one dead pixel in my right top corner you cant stee unless everything around there is lit up, but when it gets dark like in the sliding menu you can see it...is this acceptable and will it get worse as in more dead pixels later on?
Solved!
Go to Solution.

It's always annoying, but I am not sure of Nokias policy on dead pixles. I had dead pixles on my computers before, but never on a cellphone. I had one on the Dell laptop I am using now. It was dead from the beginning, but after 2 months it dissapeard. Now the screen is perfect.
I have read a lot of posts on other forums about pixle massage and programs to get the pixle back, but as I have understood, it's a difference between a dead pixle and a stuck pixle.
If nobody can answer you on this, I would use the contact link and ask about it, or take it to a carepoint. But as i mentioned, I don't know what the policy is on that issue is.
Personal opinion - the screen is small and it's annoying. It should be covered by warranty and get replaced.

Dead Pixel !!! What is the acceptable limit ?

My iPod Touch has a dead pixel which I observed very recently. What is the acceptable limit before I need to request for replacement? Its about 6 months old now.
Thanks,

The link explains apple's point of view. However, if a dead pixel does come in itouch, do i need to worry ? Does it increase the possibility more dead pixels ??

What does a dead pixel even Look like ?

I posted a thread 24 hours ago that ended up w/ a missing section, then 2 replies to finish.... a real mess that went deservedly unanswered.
I'm sure I can do better :
Suddenly I've got 2 "bits of dust" towards the lower right corner of my 24" display. They're different sizes ( the smaller close to a pin-head ) and the slightly larger one is a much darker shade of grey. They're also roughly-edged...misshapen.
They look like pieces of grit , is it even possible for a foreign particle to "ride in on a CD" and end up visible within the display ?
I'm sure that's doubtful, but I don't know much beyond what they "look like"
I've tried the Pixel-Fixer widget, but have seen no effect.
I'd just like to hear what else others may have had, the better to determine what these interlopers actually are !
thanks, Dave

The LCD is a sealed unit before it's placed in the computer so no it's not possible for foreign particles to "ride in on a CD". It may be possible for dust to get under the "glass" that covers the LCD, but again, not from a CD.
I'm sure that's doubtful, but I don't know much beyond what they "look like"
Apple has a decent article on pixel anomalies. In order to keep LCD costs down, a certain number of pixel anomalies are considered "acceptable" by most manufacturers. Some resellers offer a dead pixel warranty for an extra cost. They lose money with individual LCDs that are returned with pixel anomalies that are considered "acceptable" (the manufacturer would bill them for repair or replacement) and usually sell them at a reduced cost. In the long run, though, most LCDs don't have pixel anomalies so the more dead pixel warranties they sell, the more profit they make.
I've tried the Pixel-Fixer widget, but have seen no effect.
Software like the Pixel-Fixer widget are often just temporary solutions. Stuck pixels usually indicate a hardware issue with the LCD matrix and the only guaranteed way to make sure they're gone is to replace the display.
This picture mistakenly refers to a "bright" pixel as "dead". When the pixel is stuck in an open position (allowing light to pass through) it's a "bright" (sub-)pixel. When it's stuck in a closed position (blocking light from passing through) it's called a "dark" or "dead" pixel.
This picture shows a dead (or "dark") pixel.
Hopefully that clears some of your questions.

IPad 2 - Dead Pixels

I just sent my original iPad 2 in because it had a bunch or dead pixels in the screen. My replacement iPad just got here and there are still more dead pixels in the screen. What do I do?

If you have dead or stuck pixels on an iPad 2, you need to make an appointment with the Genius Bar at your local Apple store. If found to be defective, Apple will likely replace the unit. Make sure you back it up before you go to Apple.

Dead Pixels - Two Separate iPads

I recently purchased the 64-gig WiFi iPad in black and noticed that it had a cluster of dead pixels. Took it back to the Apple Store today to do an in-store exchange. The store had only one unit left, so we opened it up just to make sure it was okay. The salesperson turned it on and we both noticed that it had... more dead pixels, this time in the center of the screen. Since it was the only unit left, I was told that there was nothing more that could be done for me other than giving me a refund and was told that the store cannot order a replacement unit for me and that I'd have to either re-order online or find one in stock again.
It's so disappointing to finally get one and have this happen. Is anyone else having similar issues with units bought in the recent months? Is this a common occurence or do I just have bad luck? I'm thinking about waiting a few more months and hoping it was just a bad batch.

That's a good idea; they let me turn it on and check after I purchased last time, but it would be better to check before I actually pay for it. Again, I'm glad that I was able to get a refund and not be stuck with a defective iPad, but it is rather annoying to have to stake-out various retail locations to find the model that I want in stock. It seems that the Apple stores are pretty tight-lipped about upcoming shipments and when they expect new iPads to be in stock. It is frustrating to have finally found the model I wanted, bought accessories and apps, only to end up with no iPad in the end.
