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%:

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.

Satellite 5100 - Question about dead pixels. Is it really dead pixel problem?

Hi,
I've got Satellite 5100-603. There have been some dead pixels on display. I don't know is it really dead pixel problem or not because the black area seems to be behind the screen. When i move left and right sides, the black area moves left and right sides too (as if the black area is behind the screen pixels)! And i can tell that all pixels are working OK when i look from the right and left sides of the display (because the pixels that seems to be dead, changes at different looking angles).
Are there really dead pixels or is it some other problem?
Is there anything that i can do about it?
For info, i am using my laptop for 2,5 years and there is no warranty of course...
Thanks for any help..

Hi
to answer your question I will try to make a simple description the layout of the TFT display.
I'll go from the front to the back.
In the front is a tough plexi-glass like layer to protect the screen from harm and the user from glass in case the TFT should break. It is also prepared in a way that will soften the reflections from behind (that does not go for the newer SuperBright screens).
Behind that is the 2 layers (at least 1 of glass, probably both) that hold the actual matrix of the pixels.
Behind theese 2 are a very complex set of layers that take care of the backlight. It consists of various numbers of films that should spread the light from the singel FL-tube evenly across the complete screen. Not a easy task if you ask me!
Sometimes, physical stress or dirt can make 'blotches' appear on the screen and they are in fact either dirt on the backmost layer or marks on the same. If there is dirt or marks on it, that will 'shadow' the light that comes out from it and show dark spots on the screen. They are quite different from defective pixels.
The defective pixels do not change with the angle of view for example.
I think you cannot do anything about this except changing screen. The construction is very complex and sensetive.

You can return this computer and get another one.
Best.

Have 2ipod 80 gb and 120gb both with dead pixel problems

How to fix them?

Try the Hard Reset
After charging till full charge, at least 2 hours (preferably 4 hours)
Toggle the Hold switch, make sure you dont see the red mark when you do the next step
Reset the iPod -> Press Menu and Center button simultaneously for about 10 secs till the Apple Logo comes ON
Then release the buttons
Select your preferred language.
Here is the Apple support Article on the 5Rs
http://www.apple.com/support/ipod/five_rs/classic/
If it doesn't work, then you need to send it in to Apple Store for the Genius to have a look, or 3rd Party service vendor to have the LCD screen replaced.

Aperture 3 RAW conversion and hot pixel problem

I've used every version of Aperture since release, but I'm not very happy with the RAW conversion in Aperture3.
My images from earlier versions have no hot pixel problems but if I update to the new processing I can see them.
Single red or green pixel in the 100% crop image, that didn't show up before and also don't show up in LR.
The images I'm importing are NEF files from a Nikon D2x.
Is this a bug in the new RAW conversion for this camera?
It makes all of my images now unusable through Aperture if I reprocess them?

I haven't noticed the pixel issues that you mention, but I wasn't looking for that yet. Instead, my images from my Nikon D300 have been stressing A3 out as follows....
I have been having new issues with A3 now. I bought A3 when it was 1st available and had all of the same issues that plagued some users, I worked through it and until recently have loved A3.
While editing I noticed that A3 had a large number of my photos, about 30% of 34,000 images, labeled as being processed under an earlier version (A2). I decided to go ahead and re-reprocess the images, even though this step took a couple of weeks and countless crashes when I first purchased A3. Again, just over a week later, the images are now re-reprocessed within A3. And a new problem cropped up.
My Macbook is...
[img]http://jasonksepka.smugmug.com/photos/942470326_QzaME-M.png[/img]
and when I open A3 and begin looking at my images, the program is slow to respond and when it opens an image I get a very unprocessed version of lines for up to 5 seconds before the image finally loads. The image and all edits do load, but the workflow is significantly effected and I would like to know why this is happening now, and how to fix it. Below is an example of what happens with each image.

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..

Problems with new Macbook Aluminum 13" Airport not found + Dead Pixel

I'll start off by saying that this is my first Mac. I noticed today that I have a dead pixel (not a big deal I can exchange it, kind of a pain since I have already installed all my files and configured windows XP). My other problem is with the Airport card. The error I get is "No AirPort card installed". When I go into system preferences/network/Airport tab and click "Turn Airport On" nothing happens and the status is "off". I also try "Assist me..." and run the network diagnostics for the AirPort and it just scans forever and finds nothing. Now, here is where it gets fun. It works just fine on the Windows XP side. Like I said, I am going to exchange this Macbook anyways b/c of the pixel but I would like to know what is going on here incase this happens again. The Airport was working fine yesterday on both Mac and Windows. I'm very impressed with the graphics but disappointed that XP runs better on my new Macbook then Mac OS X.

If you have a USB2 hard drive you can spare (it will be formatted as a Mac drive, not FAT32) you can do a Time Machine backup of the machine before the exchange. You can then load that into your replacement machine and not have to reinstall anything. That's how I went from my old MacBook to the new one on Tues and it was very slick. Even Windows (under Parallels) was installed.

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' Cinema Display with Dead Pixel

I just exchanged an LED Cinema Display under AppleCare for the blinking/cord problem. Got the new one set up and see that it has a dead pixel. Is there a fix for these, especially being brand new, or do I have to exchange this one too?
Running tests it is very visible on a black background, then blue, and slightly on a green background. Red and white backgrounds make it so that the pixel is not a visible problem.

When I chose my LED Display, I refused two monitors because of dead pixels (green pixels on full filled white background). All of them I tried to order in on-line shops.
When I found out that Apple use LG panels for the LED Display and I understood that I have to go to the off-line shop and choose the display by myselfl. I met 2 years ago with usual LG TFT displays on my work - they all had dead pixels. (IMHO, LG is not good).
I came to one shop and there were 2 Apple LED displays - one at the exposition and one in the storehouse. Of course I wanted new one from storehouse and let manager know beforehand about not going to buy if dead pixels. He brought up the display from storehouse, unpacked, plugged and I personally start to check. I changed the background to whole white and pointed into two green pixels. "***", - I said to the manager - couldn't believe that the display costs crazy money (in Ukraine - $1400-1500) and everyone with dead pixels!
I also have 20" NEC display with perfect IPS panel that I bought 3 years ago for $800. And I should leave the buying of the Apple LED Display and back to my favourite and proven NEC it could be the right decision as you'll see below .
But the manager offer me to check the exhibition example - he assured me that exhibition one is also absolutely new and stood only 5 days in the shop. We plug it, set the background to white and ... "O, miracle! No dead pixels! After three checked displays! Can't belive!" - and this one was really total perfect.
So I forgot about to buy new NEC instead of Apple display. Brought Apple LED Display to home, connected to my brand new MBP 13, compared to my old NEC - everythnig was perfect, colors and overall picture are better than old NEC.
I was happy ... BUT JUST FOR ONE WEEK! It started to blink/flash/blackout - this is the known problem as I found out later: http://discussions.apple.com/thread.jspa?threadID=1902288&tstart=0
I'm very disappointed because I realize that if I give it for guarantee service and they offer me to change it - I'm sure that I'll got the display with dead pixels and I don't want it! So I hope that it the software/firmware trouble and it'll be fixed in the next MacOS update. If no - it'll be the disaster because I'll not be able to return the display and give my money back from the one hand (under Ukrainian laws the money back period of goods is 14 days), and I don't want to give the guarantee replacement with dead pixels!
Sorry for large text I had to to unburden myself!

Stucked green or Dead Pixel since Update

Hey to everyone...
Ive found one strange Pixel mistake on my screen... If there is Red color the Pixel stays green... but on Black., White ,Green or Blue there is no Problem...
For example hopefully you know the NBA logo... i zoom the Pixture but the Pixel ist still on the Black background... if i scroll the Pic to its blue side the Pixel does not have any mistake but if i scroll it to the red side there it is on the Black Background one green dot....
And its not the only one down under the back button there is also one which is always green no matter what color my screen has...
Im extremely sad about it, i hope sony has a solution otherwise ill bring back my device and will think twice before i get another sony device again i had untill now nokia lumia devices and never even a small problem

Hey, i have the exact same issue after i updated to .290 but Sony says that if we have 2 stuck/dead pixels thats normal and they will only service/replace the phone only if we get a 3rd or more stuck/dead pixel.
The funny thing about this is that my screen was flawless until i updated to the .290
I guess we're stuck in here....

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 pixels appeared on Macbook Pro Retina 15"

Hi,
Bought my Macbook on September / 2014 and so far no problems.
Unfortunately today a lot of dead pixels appeared on the center of my screen !
I tried to clean it but it seems to be behind the screen actually. Tried to reboot and reset SMC as request by Apple support, with no success : (
They suggested i bring it to the nearest service center, problem is i use my machine to work and it probably will take weeks to repair.
Is there any other solution ? Why this happened ? My previous Macbook was not Retina and never had this kind of issue.
I took a photo of the screens while in the google website :
Very disappointed

A 15 ft display boy that is big. Perhaps a smaller display with fewer pixels is in order.

Lenovo G460 - dead pixel, LCD can't be waken up from sleep/ hibernation , very hard to use Touchpad

I got this unit as my birthday present last week. I was very happy about it, as i've been using Dell laptops for the past 6 years of my life, this is the very first time in my life that i'm getting a Lenovo laptop, and i gotta say i'm very disappointed. Friends around me saw me carrying a new Lenovo and they all went " oh my god, that's Lenovo leh !!!", and now i must say "it's no big deal, it's only Lenovo".
after i got this laptop as a present, i'd been quite busy with work and didnt even play with it much. But when i first got my hands on this laptop, i found the touchpad is the hardest one i have ever used in my life. i dont know if it's me or the touchpad itself. Sometimes, the right click doesnt work or the pointer just stalls on the screen for a few seconds no matter how hard i try to move it. Ok, i said it to myself, fine, maybe i got too used to Dell's touchpad, this is a laptop of higher end/ bigger name and it's too hard for me to use. i could get myself an optical mouse. But the nightmare is just about to start !!!
It's labour's day, i got 3 days off work and i started playing this new laptop. After playing around with it for half a day, i left it for shower. After i returned, the display turned off. I tried every way to wake it up and they all went in vain, only a hard power off would do the job. I got online, searched the forum and found that many other users were having the same problem as i had. Ok, read that a BIOS update would solve the problem, though it's not available now. I can be patient and not a crazy **bleep** complaining about it.
just the next day, i woke up from bed, turned on the laptop, as windows 7 was starting up, i suddenly noticed there was a **bleep** dead pixel !!!!! it's so tiny that it could be so hard to see, if it wasnt windows 7 startup screen (all black with some colorful animation at the center) i wouldnt have noticed it !!! I googled on G460 having dead pixel, oh my, i'm certainly not alone !!!
Now that i have sold off my old dell laptop, and had everything set up in this new laptop, and it seems that i need to return this laptop, and certainly i'll have to live my life without a laptop for the next few weeks. I gotta say it again, i'm very disappointed in Lenovo !!!
Now please let me know how do i return this laptop for repair or whatever you call it, as i work on weekdays in singapore and return to malaysia only on weekends, and this laptop was bought in Malaysia. looks like i gotta take a day off just to send this laptop back to lenovo..........what a big let down.
have had so many Dell laptopsand never had a single tiny problem with them......

I'm banging my head because I can't find a solution to make my arch-install detect an audio CD
I assume that you mean the optical drive. I don't see a /dev/sr0 in /dev
Does it show up with lsblk or parted -l?
Looks like it's a LiteOn drive.
You can play an audio CD.
mplayer cdda://
mpv cdda://track[−endtrack][:speed][/device] −−cdrom−device=PATH
An audio CD doesn't have a mountable file system on it.

My new iPad has a dead pixel in the middle of the screen. Can I get it replaced?

I've heard that there is a minimum number of dead pixels before apple will replace it. Very frustrating because otherwise the screen is perfect, and it's one of those things you can't stop looking at. What can I do? I don't live near an apple store so I fear that shipping it away is the only option.
Any help is appreciated!

Given that you can return/exchange it for any reason within the 14-day window after you bought it, you shouldn't have any problems.
Do you live near an Apple retail store? That may be your best bet. It certainly worked for me: I ordered mine online and when I noticed an air bubble embedded in the glass, I brought it to my local Apple Store and 15 minutes later walked out with a replacement. No fuss whatsoever.

Does Apple's warranty cover dead pixels on the iPhone 4S?

I received my iPhone 4S in the mail today and a few hours after I had been using it I noticed a tiny dot on the screen. At first I ignored it, thinking it would go away, but it hasn't. I searched what the problem was and found out it is a dead pixel. Like I said it's very small but it really bothers me every time I watch a video or take a picture. If I take it to my local apple store, will the warranty cover this?

The warranty should cover it if it is a defect in manufacture. In any case, you are covered by the 30 day trial return period.
