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?

Extreme amount of dead pixels on 24" 2006 iMac intel

Currently I am in possession of an iMac Core 2 Duo model A1200 (24"), which has severe display problems. There are dead pixels all over the screen, and even when in text mode the same problems occur, but distorting the text characters. This is OS-Independent, as it happens on every OS I have tried on it. In addition to that, sometimes CDs/DVDs don't show any display when they boot, however the dead pixels are still there. I've tried swapping the original RAM with new RAM of same make/speed/capacity, and the same glitches still happen. The RAM I swapped in is known to be good, as it has gone through 7 passes of Memtest86 with no errors. The only two things I could possibly narrow it down to are the Optical Drive or the HDD. The HDD is failing (according to the OSX install disc Disk Utility), but that should not affect the display. I checked the internal display cable and it shows no signs of a break. I have tried resetting the PRAM, which did nothing to fix it.
Example of display problems (shown while running memtest): http://img812.imageshack.us/img812/8060/imacfaildisplay.jpg
Any help would be appreciated.

+However, the apple page does not seem to accept my serial number for some reason+
I would assume that it doesn't accept it because you are past your warranty period. You can still take it to an AASP for an estimate and/or repair.
As for the Apple Hardware test, it does not necessarily pick up 100% of all hardware problems, so it is not the "absolute" test to rely on. Did you run the extended test?

Dead pixel on 14 inch latop

Hi,
I've just bougt HP DV4 3029TX from local store last week.
I found out that my unit has dead pixel (or maybe bright pixel? one red pixel).
Is there anything I can do about that? The store won't replace the unit unless HP provides DOA document and HP can't provide it because it is just one dead pixel.
I mean, it's a brand new laptop, and there should be something I can do about that. I don't mind paying if it can fix my screen. I''ve contacted HP Instant support 3 times and finally they told me to contact HP service centre, where I'd need to tell theme the whole story all over again.
Any help/suggestion is appreciated.
Thanks,
Daniel

There is a pixel policy and it requires that a specific number of pixels (plural) be bad within a certain radius. One bad pixel does not make a warranty claim. All laptop makers have similar policies. It is a holdover from the days when a laptop screen was much more expensive than now and frankly I think it is time to stand behind the product a bit better, but all you can really do is make a nuisance of yourself and see if they will bend the rules.

Dead Pixel Lines Across My iMac G5

Hello. PLEASE HELP I don't know how to attach pictures here to show you what this looks like, but its about 12 inches across of non conforming pixels. One near the top of the screen middle, then two more lower middle half about the same in length. They go away sometimes, after a reboot, or when I change users. But they are there no matter which background I have up. AND also now it seem like there are problems with the same image distortion crap when I am using Safari.
PLEASE help. Is there anything I can do? or is this a hardware issue for sure.
I know the computer is not that new, but any type of warranty for this stuff?
Let me know if you have seen this happen, AND if you'd like to see pics to diagnose, let me know I can send them along.
THANKS!

Dead pixels on late 2012 27-inch iMac

i've been using the default configured starry Galaxy desktop wallpaper since i bought my iMac 27-inch late 2012 and today i noticed a small light spot near one of the small stars on the left side of my screen, it is mostly noticeable standing up and looking down at it when windows are open on that side, i.e. safari, finder windows, and on lighter solid-color backgrounds. it looks like dead pixels as opposed to dirt to me, but i dunno.

If you have had this new iMac for longer than 14 days, you can no longer return it for a replacement.
You might be able to get a new, replacement LCD panel installed under AppleCare, if this bothers you or you are just going to have to live with it.
There is a certain amount of dead pixels that determines if the LCD is good or defective.
Every LCD panel is prone to dead pixels. The pixel can be stuck "on" (white) or stuck "off" (black).
If this is the only pixel that you found that is dead, then it maybe considered OK and not defective.
If you had the LCD replaced, there is no guarantee you wouldn't get a replacement LCD with another or a few stuck pixels.
In the near future or before your free year of AppleCare expires, I would strongly consider budgeting, purchasing and registering with Apple for the 3-year extended AppleCare warranty plan. You will need it.

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.
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.

27¨ iMac - Dead Pixel Madness!

Hi,
Today was a very interesting and exhausting day for me.
I purchased a new *27¨ iMac* a few days ago, I set it up and I noticed that there is a *dead pixel*, right in the middle of the screen.
I told myself to live with it but a friend of mine said 'Are you crazy? You paid 2000 dollars for it, go and get a new one.' And I headed to the *Best Buy* store, that I bought my iMac at.
Customer representative took a quick look at it and said 'Oh that's right. Let's give you another one.'
I got the new one and asked them to check it for me before I took it home. They opened it and... Yes. That one also had a *dead pixel!*
He said 'That's unbelievable. Let's get another one'. I got another one, we opened it and... No way! There was two of them! Nobody believed it, people started to laugh and then the supervisor came. She said, 'Sir, I'm so sorry for this but we cannot open another box. Do you want to go to another BestBuy and get a new one there?'. I said OK and went to another store... +(By the way, that meant 'We want to sell the other iMacs with dead pixels to someone who doesn't notice', which is not acceptable in my opinion... Anyway...)+
As you may guess, the same thing happened! They opened 2 boxes for me and both had dead pixels!
*2 different stores, 5 iMacs with dead pixels in a row!*
Supervisor of the other BestBuy store also came to me and said, 'Sir, I'm sorry for this but we cannot open another box. Do you want to go to another Bestbuy and get a new one there?'. I said 'No, please give my money back and I'll go to an *Apple Store* and buy a new one there.'
They did it and I'll wait 48 hours for my money to be transferred back to my account. In such busy days, I'll spend two days without a computer at home...
After such a weird day, I began to think if the guys in the Apple Store will open the box for me and try it. And I also wonder if they will exchange it if there's a dead pixel. Does anyone have an idea about this?
+I know there are some topics about the dead pixel issue, but I think this one is a bit different :)+
Thanks in advance.

Here is the update
I went to an Apple Store and told them my story. The guy that helped me said he had never experienced such an issue before and he said 'OK, let's get you a new one'. He got a box, opened it, turned the computer on and... Yes! One more iMac with a dead pixel, this time in an Apple Store!
6 in a row! This might be a record! I'll contact Guniess for this soon...
Then I got another one and finally I found a 27 inch iMac in Los Angeles, without a dead pixel. What a success story, huh?
Thanks for your replies and be very careful while buying a 27 inch iMac

IMac 27" Dead Pixel....

Hi
I'd purchased an iMac 27 inch online from the Apple Store on the 20.05.2010 and taken out Applecare. While cleaning the screen today I noticed a speck of dust behind the screen, on further inspection I've noticed a dead pixel. I spoke to Applecare, a collection has been arranged so they can take it away and inspect it. Anybody any ideas what the outcome of this will be?
Thanks
Baz

Unless they are saying that they will replace the display then cancel the pick up. On a display that large Apple rarely does anything for just one dead pixel.

IMac dead pixel

I Think my Imac has a dead pixel. It's the latest iMac 27 inch display and it has a black mark on the screen. If I take it to apple what will they do?

If I take it to apple what will they do?
We cannot second guess what Apple will do, however you should go in educated about their policies on dead pixels. They like most manufacturers will not replace a display for a single dead pixel however if there are number of dead pixels that negatively affect the appearance they are likely to replace the display.

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

What is Apple's dead pixel policy for MacBook Pro 13 inch 2011?

I have just noticed a dead pixel in my MacBook Pro 13 inch. Is it possible that i could have my Mac replaced? If not, what do I do and what is the policy? I do have Apple Care. Thanks.

One thing I'm fairly certain of is that Apple will choose to repair the unit instead of replacing it. Since you wisely purchased AppleCare, they should repair it if you're in your 3-year warranty (and, obviously, you are).
Good luck,
Clinton

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 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.
