Dead pixels or something

My question, before I even get into the story, is whether or not this is worth pursuing...
I bought a 20" Intel iMac in late 2006. It's still under AppleCare warranty. Shortly after I bought it, something went wrong and it would only turn on intermittently. The folks at the Apple Store ran their tests and came up empty. I finally took it to Micro Center and they replaced the logic board and solved the problem.
This past month, I've been having hard drive and optical drive issues. I was having major slow downs, and Disk Verify was telling me the volume was damaged, and the optical disk drive would only accept the discs it wanted to. I took it to the Apple Store, they did an erase and install and told me the problem was solved. Obviously it wasn't, which I only found out after re-installing a hundred and fifty gigs of software and data and getting everything organized again. I pitched a fit and they finally replaced the HD and optical drive.
I picked it up today and starting reinstalling everything again. Then I noticed all these little grey dots on my monitor! I used to have one super tiny red pixel and one grey smudge. Now I've got an additional red pixel and about 13 grey smudges. (Just dot-like smudges, but I can see them and they're totally distracting.) I mean, I can still work on the machine, but this kind of ticks me off! I don't know if some dust got in there when the machine was open or what.
What do you guys recommend? It seems like when that first red pixel appeared almost two years ago, someone told me that was normal and unless a certain percentage of the screen was affected, I had to live with it. Well, these dots weren't here when I put the machine in the box to take it to the Apple Store! Any suggestions?

My initial reaction to that picture is there's a defect in the display. It doesn't look like a video card defect nor something caused by some object under the glass to me.
You don't say which monitor that is. But if it's an imac-like monitor (or the recent crop of apple stand-alone monitors). and you are interested in removing the glass to look under it, there are instructions on removing the glass covering the screen. iFixit has some. And if you put something like "remove imac glass" into google you'll find a whole bunch.
One final thing; your sig says you are using Lion. Did you see this problem with Snow Leopard. Anything involving lion I hold suspect

Cheers!

If you are looking on a different page is the mark always in the same place? If so it could be a dead pixel.
If you took it in I don’t think they will do much about it, as I think 1, 2 or 3 dead pixels are probably within the tolerances allowed for that screen.
You can always take it in to see what they say.

Dead pixel and something stuck between glass and LCD

Just got a new Apple Thunderbolt Display (27-inch). As you can see from the photo below there is one dead pixel and some material stuck (that move around a little when you press the screen).
Apple will replace this if I take it back won't they?

You can exchange for a new one (that is what I did). However, using suction cups you can remove the glass screen for cleaning( only held on with magnets). Of course that will not solve the pixel being out which is unusual for TBD.

Dead Pixels? Broken Screen? HELP!

Hi everyone,
So about 3 weeks ago I bought a brand new 8G iPod touch.
I use it almost every day, and I've never had a problem with it.
Recently, I started getting battery issues which weren't drastic but were obvious enough to bug me, but I let it slide because the amount of time I used the ipod wasn't affected by it.
Just this morning, I was using it, and after I was done I placed it on my desk. Without any use between the time I had put it down, and when I came back for it (About 3 hours), A patch of dead pixels or SOMETHING about the size of a fingernail formed. I got pretty annoyed at this, but I didn't move it anywhere else, because I plan to take it to the store tomorrow and ask about what can be done.
Though, another hour or so after that happened I checked it again, and the patch had gotten bigger.
This kept happening until the patch became a line which strewed across the whole screen.
After that, the screen began to flicker and pulse like a broken TV.
What the heck is going on!?

Pictures to show the damage.

Hey what happened, did they give you a new one, cause exactly the same thing has happend to mine, I even had it in a protective case thing and grey lines appeared on the screen, But the screen didn't flicker or pluse.
I've only had it 5days!!

MacBook Pro w/Retina has moving dead pixel (white)

I recently purchased a MacBook Pro w/Retina and have an annoying issue that comes up from time to time. Once in a while a bright white pixel will appear in the middle of the screen. It stays put while it is there and I can drag screens around and nothing changes but then suddenly it will go away. After awhile it will popup in a new location and the same thing will happen. Any ideas what this might be? Is it an issue with my screen?

Anyone reading in 2013/2014 running Mavericks (and worth a try with earlier OS) and having this issue on an external display, I wrote about the deceptively simple solution here: http://forums.macworld.com/index.php?/topic/153791-dead-pixel-or-something-else/
Basically, in display preferences try moving the menu bar (that small white rectangle on the arrangement screen back and forth...that's it.

Not a dead pixel.....but actually something stuck under the screen

I just got home from the Apple Store where they swapped out my iPhone because on some phone calls there would be a crackling sound like the earpiece in the phone was blown or something. I got home and was getting it set up and on white screens a see a little dark dot. I thought it might be a dead pixel but when you turn it off and look at the screen and turn it just right you can actually see something underneath the glass. I don't want to be a pain but this is really going to bug me. Should I take it back again?

Yes I have had this problem
The first phone I had, had a "stuck" pixel (it was always whiteish/blueish/greenish on any black/dark background). It was only one pixel but they exchanged it.
The next had another bad pixel and a piece of lint or something...they exchanged it again, though this took some arguing and second opinions. Finally I found the manager who agreed with me unlike the guy at the "genius" bar.
This one AGAIN had Many pieces of noticeable debris. They exchanged this one right away, no questions.
Now I'm on my 4th phone haha and it has Several "stuck" pixels. Around 5 or 6 actually noticeable ones. Its really driving me nuts. I want to have a phone with a good screen and have all this exchanging nonsense to be over. It also has another piece of dust you can see on white screens and when the phone is off.
I brought it in and they said to give it a few weeks and see if it gets better or worse. I said okay and left. It's just too upsetting for me. The thing was over 600 bucks. I'm going to another apple store tomorrow. Hopefully they can fix or replace it with one I can examine before I leave.
Did they replace yours with a good one?

Problems with stuck/dead pixels, battery life, ICS, and other problems

Stuck/Dead Pixels:
I bought my Droid Razr at around the 21st of December last year. On or around Christmas, I found a bright red pixel on the very bottom of my screen. Unlucky for me, I was leaving for Florida on Christmas Night. I got back on December 31st. Sometime in the first week of this year, I visited my verizon store and told the customer service lady that I had a dead pixel on my screen and had just bought it. But, she told me that she needed the manager to fix this and there was no manager there. For the next week I was busy with school and sports etc and was not able to go back to the store. It was now past my 14 day return period. So I decided, its only one pixel, most people won't notice it anyway. So here I am 5 months later, just starting to discover more pixels dying on my screen. I now have the one bright red one, two light blue ones, and one dark red. I have no idea what the return policy is on defective phones, and the verizon site is designed so that you can't find anything. And an FYI, I have tried stuck pixel removers and other apps, which haven't been successful.
Battery Life:
I have also been finding more problems with my phone. The battery life is terrible when 4G and even 3G are on. I actually see no difference in battery consumption between 3G/4G. My battery dies about 4-5X faster when data is turned on, compared to using no data. I know it isn't because of the apps I installed since when I use WiFi, the battery is alright. I also make sure that my RAM isn't above 400MB, so that the processor doesn't use a lot of battery. I feel like I completely wasted my money buying the Razr. Mainly because of the fact that the Razr Maxx was announced two weeks later, which has about 80% more battery. Not only this, but I've seen the Razr selling for only ONE PENNY on amazon over the past month and it still is. I payed $300 on my Razr.
Ice Cream Sandwich:
After these major problems comes another one, that I bet all Razr and Razr Maxx customers are still thinking about. When will I get Ice Cream Sandwich? It is very disappointing when you are told that you will be getting an upgrade in early 2012, and are still wondering where your upgrade is 5 full months in. From what I understand, we won't see an upgrade until the end of June, since Motorola has posted on their website that "rollouts" would begin in the second quarter. Even if they release it by the end of June, when will it get to your phone? Maybe another week or two for some people. This is another thing that I feel I wasted my money on. My brother told me to get the Nexus because of ICS, but I trusted Motorola that they would upgrade my phone in a timely manner. WRONG.
Phone Freezing:
One more problem that I've had is that the phone will freeze. Usually you only need to turn the screen off and on, but once in a while, you have to completely reboot your phone. When I was coming back from Florida, right as I was about to get home, my phone completely froze. I was about to go return it, but after about 15-20 minutes, it became unfrozen.
Motion Sensor not functioning:
Another problem, an annoying one, is that sometimes the motion sensor that controls portrait and landscape mode will just stop working. Some of the games I play are completely dependent on the motion sensor. It is very embarrassing when you are trying to show off to an iPhone friend and major components of your phone aren't working. They always tell me "why didn't you get an iPhone?". And I really just wanted to have a phone that didn't look like everyone else's, but I guess that comes at a cost. When the motion sensor stops working, I have to shut down my phone and restart, which takes a couple minutes.
Problems with camera:
My last problem would be with the camera. Sometimes if you bring the camera close to something, like a barcode, it will keep trying to focus, but never will. Another problem is photo quality in low light situations. It seems like the camera can't focus because it goes from being very dark into being bright because of the flash. I doubt this can be fixed because it's hardware, but a potential fix could be having the option to keep the LED light on during picture mode, that way the camera will be able to focus correctly.
In Conclusion:
I really just want someone to tell me how to return my phone for a new one, due to the dead pixels. I also wish I could be upgraded to the Razr Maxx because of the poor battery life on the Razr, but from what other people are saying, that probably won't happen. And finally, if anyone has more info about Ice Cream Sandwich, that would be awesome.

Well since it's a Manufacturing Error it should Fall under your Warranty if you got one with your Razr. You know you can Call C.S. an they can Assist you with the Matter on it.. Just remember to have another phone so they can Trouble shoot the One that is Experiencing the Issue an when you talk to them go over thing. An they should send you C.G.A.N unless they request you to send it in before you get anther one. If you feel Better going to the Store try that. And Good Luck..

Dead pixel in my iPad

I was grievously disappointed to discover a dead pixel near the center of the screen in my iPad yesterday just before leaving to the U.S. from Japan.
Almost everything I have ever gotten from Apple has had a defect like this and I've had to fight fight fight to get it fixed each time.
But... I decided to see if I could get it replaced while here in the U.S.
So I made an appointment at the Genius Bar at the Apple Store at the Chestnut Hill Mall here in Boston and brought the iPad over at 2 pm.
The guy at the Bar was nice, saw the broken pixel and immediately said he'd swap it for a new one for me! So I was very pleasantly surprised and glad about that.
Then the new swapped one ALSO had a broken pixel - almost in the exact same area!!!
So he sort of sighed, but did a 2nd swap out for a 3rd iPad. This time we looked and looked (while impatient people were backed up to get help) and couldn't find a single broken pixel.
So fortunately this problem was resolved very nicely by Apple and I'm good to go. Using a 2 GB AT&T contract with an AT&T SIM card while I'm in the U.S.
I'm surprised that two iPads in a row had a broken pixel, and almost in the same area. But I was really pleased at the friendly, reassuring service I got at the Genius Bar.

Yes, extraordinary bad luck.
While I haven't had problems with my desktop Macs (iMacs) or my iPhone 3G, every other mobile/portable device I ever bought from Apple, going back 20 years, has had something go wrong with it, usually from the start, often multiple times. Examples:
- Duo: the screen had multiple broken pixels and needed to be replaced from the start.
- iBook: the wireless card (then an option) was set improperly and wasn't working. Needed to be sent back for repair.
- PowerBook G4: broken pixels needing replacement from the start, keyboard problems requiring top case and kb replacement. Also, that model had a really poorly designed cover that never closed properly (the famous wiggling cover problem.)
- MacBook Pro: Failure 2 times in 3 years of my trackpad requiring replacement; broken pixels requiring replacement; hard disk failure requiring replacement. Two replacements of mother board! The last one 2 months after my AppleCare warranty ran out, but Apple fixed it anyway. Keyboard needing replacement. I'm using it right now on my trip to the U.S. and it's still working after almost 4 years, but it definitely has taken advantage of the AppleCare warranty multiple times. And I'm not a rough user - I almost never take it off my desk, except on travel.
- iPod nano: Don't even get me started on that one. The screen was tilted (big discussion thread here) - they sent me 3 replacements, one worse than the other. I finally had to go to the Japan consumer affairs agency to force Apple to give me a refund. Which they finally did, with an apology and a gift certificate to use at the online store.
- iPad: broken pixel needing replacement, followed by a 2nd iPad with another broken pixel needing immediate replacement.
This is just what I can remember off the top of my head.
Unless I am unusually unlucky, my own sampling over the years tells me that while Apple support is great and they take care of the problems after the fact, they definitely have quality issues coming out of the factory to begin with.
I always have to "mentally prepare myself" before buying an Apple product because I know I am very likely going to have to invest a certain amount of time in dealing with Apple support and getting things fixed afterwards. Eventually it turns out ok each time, but just knowing I will have to deal with it is stressful.

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

Example of Aperture dead pixel problem

A lot of people have been complaining about green pixels in their converted output. I noticed a pixel in the RAW image as rendered within Aperture and went in for a closer look. It's more like a dead pixel. I've put up crops of an image mangnified at 300%:
Aperture:

Photoshop CS2:
http://www.pbase.com/chrobb/image/53050270
Make sure you're looking at the "Original" size of the file (located at the bottom of the webpage)
This is a pretty glaring example of some major processing problems with CoreImage. I'm going to send a bug report to Apple.
G5 1.8G SP, 1.5M RAM Mac OS X (10.4.3)

I think this was one of the biggest concerns that I had with Aperture: the reliance on OSX code to decode the RAW files. If Apple were to re-write their RAW file processor or need to tweak it to fix this bug, it would likely need to come in the form of an update to the operating system. A couple of problems with that:
1) Sometimes, because of other problems with an update, you might not want to update your OS. Say, an update fixes something in Aperture, but breaks Mail. Which is more important?
2) OS updates are likely to be released more slowly than application updates. This may not be the case since Apple may release Aperture product updates even slower, but there are a whole slew of considerations that developers need to take into account when getting something merged into the much larger OSX train.
Maybe Apple can release small RAW updates that only affect the portion of the OS that deals with RAW. I seem to reall them doing that with other apps. It remains to be seen how well and how quickly they respond to these issues. I know a lot of people are probably waiting to see how responsive Apple is before entrusting their library to a proprietary application.

Hot / dead pixel elimination in later versions of Camera RAW

Hi!
I was wondering if we could get some under the hood info on how Camera RAW handles hot / dead pixels. The standard answer 'Camera RAW eliminates these automatically' does not apply I'm afraid. I've seen more and more of these stuck pixels in my final output over the last few CR versions. Now, it could be my camera showing its age, but I'd like to know more about how Camera RAW maps stuck pixels.
I've just re-developed a set of some stage performance from last year, Canon 5D Mark II, high ISO and pushed, yes, but thats my whole niche. There's stuck pixels in all of them in the same spots. So I wondered how camera raw handles the whole mapping / processing of hot pixels. The set of images are here, and there's access to full size images also: http://www.flickr.com/photos/mvejerslev/sets/72157627732199199/ (I did clone out the stuck pixels on just a few of them though). It's a mix of processing version 2010 and 2012. Did not make a difference to the stuck pixels.

Well, the issue with higher ISO images is: what's a hot pixel vs. what's a result of salt & pepper noise–those are different artifacts...
When you start ramping up the ISO (and use PV 2010 or 2012 without luminance noise reduction) the likelyhood of random bright (more or less) pixels (or subgroups of pixels) goes up.
The hot pixel fix is still in LR/ACR...but it becomes a battle between what's a hot pixel vs what's a result of camera noise...and ACR/LR tend to be very conservative when it comes to mapping out a hot pixel (or dead or constantly a certain color pixel).
ACR/LR can really only estimate what constitutes a hot pixel because there's no way of recording the XY position of a single pixel and telling it how to handle the mapping. It's an auto thing and as such it's subject to sometimes not working perfectly...
To really determine the issue, one (or Eric) would need an actual raw file–not something that's already been processed and resample. The more examples of ACR/LR not doing an optimal result the better the likelyhood somebody will look at doing something about it.

Dead pixels appeared on my retina display. Can it be repaired?

My MacBook Pro Retina is a little over 10 months old, and recently, two areas of dead pixels have shown up on the screen. I have no idea what made them appear, as I baby this machine much more than my prior original MacBook Pro (7 mostly problem-free years!). The one spot is a bright white when the screen is black, and the other is a smaller gray dot.
I've tried to keep this machine as like-new as I can, and it doesn't go a day without getting a wipe-down from a micro-fiber cloth. I keep it in an external shell, and it is never touched by by my kids. Still, I somehow got these two areas of the screen that do not turn black.
Is it possible to have the display repaired, or is this something I'm just stuck with? I always get AppleCare with my laptops (out of paranoid fear), but I can't tell if something like this is covered.

I don't believe there is a minimum # of dead pixels, but mende1 knows better than I.
Before I got my first Mac and while I was looking for more information about Macs, some websites published an Apple's "secret" document about dead pixels, and that's what it said (Apple did not replace displays with a "small" number of dead pixels even if it was in warranty, and some users have had this experience).
As I told you, this may not be true and the display gets replaced, and also we do not know if that applies to the MacBook Pro with Retina display, but if the Mac has got Apple Care the display should be replaced

Macbook Pro Retina (2 or 3 dead pixels)

Hello,
My MBPR is around 8 months old and does have 2 or 3 dead pixels around the center of the screen. I didn't buy Apple care (i stil can) but i'm wondering if i even need it for a replacement/repair. Does Apple even does something with or without the Apple Care for only 2 or 3 dead pixels?
I hope someone here got any experience in this.
Cheers!

The Apple warranty on the MBPr is one year from date of purchase so you are within the warranty period at 8 months. Take the MBPr to an Apple store genius bar and discuss the display with the technicians and see what they will do about it. Some have said that 2 or 3 pixels is below the threshold for service/replacement. But you don't know for sure until you take it in and see what the techs will do about it.

How to fix stuck/dead pixel on my iPad 2

I just got an iPad 2 and I found out that there is a stuck/dead pixel on the screen. I thought that I could ignore it at the beginning but it just gets too annoying and it grabs my eye when doing anything. So I need to fix it. But first I need to know is it dead or stuck.
On some colors it appeared in two different colors, it changes each time I look at it from different position.
So on white : blue and red
On black : it does not appear
On purple : red and blue
On red : blue and red (so it does not appear)
On blue : black and blue
I hope I gave enough information. Waiting for your help...
P.S. I entered on YouTube and saw a video called stuck pixel fixer or something like that and I opened it for like three minutes each day for about three days now, and it did not fix it, do I need to play it for a specific time? Or do I need something else?

there is an app (cant remeber the name sorry) but it it basical flix up soild images of colour (red,blue,yellow ect...) and it did it at a speed to try and shake the pixel into working agian, sorry i cant remember the name....but its sumit like screen cleaner or sumit like that.

I have one dead pixel on my iPad Mini, besides sending it back is there anything I could do?

On my iPad Mini screen, since I have bought it, there has been one small black dot in the middle of the screen (I'm presuming a dead pixel because its absolutely always there). And I'm not too bothered about it but if there was something I could do without having to send it back that would be great!
Thanks
Ryan

My iPad Mini arrived this morning with a dead pixel. I am going through the exchange process now. Hopefully the next one I recieve will not have this problem. Is this a popular issue?

Dead pixels or something
