Stuck Pixel: not typical. Might be software related.

Well my friend has a mid 2009 macbook pro with integrated graphics. She just noticed this afternoon that there was a white pixel at the upper left hand of the screen which shows up on the black background in that corner. I immediately assumed it was just a stuck pixel and downloaded J pixel remover to try and unstuck it. The interesting thing i noticed while helping her out over ichat screen share was that her stuck pixel WAS actually showing up on my screen. now a stuck pixel seems to be a screen problem which means it SHOULD NOT show up on my screen. This leads me to think there is some problem with the signal the GPU is sending off which would explain why it shows up on my screen as well. Is there a way to reset the GPU? has anyone experienced something similar? Any ideas or thoughts? Thanks in advance.

Stuck pixels not auto removed Lightroom 3

Lightroom 2 automatically removed any dead pixels on import but my Lightroom 3 is no longer performing this function. What's going on here? Is there some way to turn this function back on?

Huh. This has /never/ happened for me. And I have a busted up old camera I use for IR stuff that has stuck pixels like crazy.
Oh, I get it, I think. It is probably ACR that does this, but for raw images only. But the busted up camera I'm talking about is only good for making JPEGs. I bet that is my misunderstanding.
So, as for the OP, it might be worthwhile seeing if they use any other ACR apps, and see if perhaps the pixel mapping done there has been tweaked by some other app.

Stuck pixels? Not sure...

I've been reading a lot of posts this morning about stuck pixels, and I thought maybe that's what I have, but mine seem to be a little off from what others are experiencing. I woke up my iMac (bought in May 2006 from the online Apple store, so warranty is definitely over), and noticed a straight, vertical line of light blue going right down the entire center of the screen. I thought maybe it was just on the Safari page I had open, but it was on the desktop as well. I restarted, thinking something had fritzed, but it's still there now.
On some of the other discussions there were links to pixel programs to try and fix the problem yourself. I did the Pixel Fix widget, and it had no effect on the line. I also used Pixel Check, and when I tried all the different colors, the line was there for Blue, Green, Red and Black, but NOT White. I'm not entirely sure what that means, though.
So far massaging the line hasn't done anything, and I'm scared to press too hard and mess something else up. Does anyone have any ideas of something else I could try? If I have to live with it, I will, but it's pretty horrible being down the center of the screen. I can't imagine trying to watch a movie on here ever again with it like that.
Thank you for any suggestions!!

It probably happened just as you turned it on that time. It wasn't random, just at the point when something failed. There's no telling whether the screen will get any worse or when, but I don't believe there's anything you can do to prevent it. If you can live with it, or have no choice, then carry on. Hopefully it wont bother you too much.

Stuck Pixels after Installing iPhone 2.0.1 Update

Has anyone else noticed any new stuck pixels after installing the iPhone 2.0.1 update?
As you can see in the image linked to below, my 8GB iPhone 3G began displaying a stuck pixel in the upper-left immediately after installing the 2.0.1 update. At first, I figured that this was an average stuck pixel that coincidentally appeared immediately after applying the 2.0.1 update. However, after further examination, I don’t think that this is a normal stuck pixel.
http://skitch.com/macmanx/1igt/stuck-pixel
A few hours later, my mother updated her 8GB 1st gen iPhone, and as you can see in the image linked to below, she now has a vertical line of stuck pixels in the same region as mine. Since her stuck pixels also appeared immediately after installing the 2.0.1 update, I’m beginning to think that my stuck pixel may not be an isolated issue.
http://skitch.com/macmanx/1i88/stuck-pixels
I have tried to restore both iPhones, adjust the brightness, apply light pressure to the stuck pixels, and run the Knox Pixel Fix for iPhone. Neither method worked. To further complicate the issue, the stuck pixels appear to flicker when viewed through the LCD screen of my digital camera.
Stuck pixels are (as the name implies) stuck, they do not flicker. This, added to the fact that the issue occurred immediately after applying the 2.0.1 update, leads me to believe that this may actually be a software issue, possibly involving a conflict between the display drivers in the update and the display hardware shipped with certain iPhones.
If you have also noticed new stuck pixels after installing the 2.0.1 update, I'd love to hear that I'm not the only one seeing this. And, if you have somehow managed to resolve the issue, I'd love to know how you did it.

As already pointed out, "stuck pixels" are hardware related. They will be evident all the time, regardless of the particular screen being viewed. If they show only on particular screens, it isn't a dead pixel, but a software/ driver issue. I see a horizontal line in my Unlock Screen that I didn't notice before 2.0.1, but I'm not sure I really looked for it before. However, I don't see it in other screens with a black background such as the Home Screen, indicating it has something to do with the Unlock Screen image, and not the LCD pixels.

A lotttttt of stuck pixels

I believe I have a lot of stuck pixels here. It's nothing I can't deal with, but I'd rather them not be there. Any suggestions? Some are pink and blue and grey when the screen turns to a black background (not sleeping, like a video) so I believe they're stuck and not dead. I could be wrong though. See picture for reference. Any help would be greatly appreciated.

You can try working through the 5 R's of troubleshooting to rule out any possibility of data corruption or software errors, but that type of scenario is usually hardware related with the iPod's LCD dispay.

Software Related Graphics Problem

Hey Guys,
My iMac C2D 17" early 06 has been having some software related graphics problems. It hasn't occured a lot but it has happened a few times. Small black dots or bars may appear but when I click or hover over them with the mouse, they go away. So, I am thinking that it may be the hard drive because it could be misreading something that could make it not show certain pixels but I am not really sure.
Any help will be well appreciated.
Thanks

RAM Specs:
2 sticks of 512 MB PC2700 CL 2.5 Apacer RAM. I don't know if this matters but they're in DIMM slots 1 & 3.
I downloaded nForce drivers (version 5.10 as Richard suggested) and everything installed fine. However, the computer freezes whenever I'm using MSI liveupdate.
So, instead of using liveupdate I downloaded the nvidia drivers directly from Nvidia.com. During installation the screen flickered three times, and immediately after this the only thing appearing on the screen was a blinking cursor in the upper left; the computer just hung at this point.

I have da stuck pixel on my screen. On my iphone5. What can I do?

Hi! Sorry for the late reply.
You could go back to Verizon, though it's highly likely they might send it away for repair. If you go into an Apple Retail Store instead they tend to do everything on the spot.
Not entirely sure with Verizon's options (Im in Australia) but can only give it a try

Stuck pixels in the thousands

Sorry to harp on stuck pixels I know there are alot of posts on this subject. However in most cases people are talking about 1 or 2 pixels, in my unfortunate situation I have hundreds if not thousands. A 5cm x 2 cm portion of my 14 inch screen is covered in green "stuck pixels". One line is permantly stuck on green however the remaining stuck pixels appear to change colours (pink or green) depending on what is on the screen.
Strangely I used Pixel Check (http://www.versiontracker.com/dyn/moreinfo/macosx/11661) and only the top green line showed up as being "stuck on green" the rest of the stuck pixels didn't show up. However after the test they reappear.
I have tried using "pixel fix" software flashing for hours on end trying to "unstick" the pixels and also I have given them a good rub but all has failed.
I bought the ibook over 18 months ago so it's no longer under warranty.
I am now contemplating getting the screen replaced, however I just wanted to know if anyone out there had any ideas on my situation. Is it really a bad case of the stuck pixel anomaly or something else?
thanks

Hello
I had 6 dead pixels on my macbook pro screen. I was quite annoyed about it.
After a huge research I did find solution. At least you can try it is for free
It is a small Jawa applet which flickers and can unstuck pixels.
I had 6 dead pixels. After using this flickering applet for 10 minutes 4 of the pixels disappeared They were in the center of the screen.
The last two are placed on the top of the screen. On the top dock where the blue apple is. Fortunately there is no way I know about how to hide this dock. Therefor stuck pixels remain. (if you know how to get this flickering applet over entire screen please let me know, the videos on the website did not work for me)
Anyway check this website and good luck, Hope it helps.

MB Pro Restarts/Reboots by itself - is this hardware or software related??

I've replied to a number of posts regarding this topic here but no one seems to have answered this question sufficiently.
My MB pro will just restart itself randomly. It usually happens when I'm not doing anything which makes me think it might be due to some process that happens when the computer is managing power (sleep settings, etc). I've tried changing all my energy settings as well as resetting SMC, pRam, etc. but nothing seems to work.
I'm thinking about doing a clean OS install if this is some software related issue so any input is appreciated!

I've the same problem after the mainboard has been changed two weeks ago. There are no signs or error messages. The MB restarts randomly during screen save.
Last restart time was today, 13:13 (1:13 pm). See enclosed extract of the system.log.
Any idea?

Macbook pro retina dead/stuck pixel and warranty question

So here's the situation. A couple of weeks ago I brought my macbook pro 15'' retina into the apple store because the speakers were buzzing sometimes. It wasn't a huge problem, but my 1-year warranty was about to expire so I figured I'd bring it it to get fixed.
About a week later, I went to pick it up and I brought it back home. I tried out the speakers (it was too loud to hear them in the store), and the problem was still there. It wasn't worth complaning and bringing it back because I usually use external speakers anyway, so I figured I'd just live with it.
But about a week later I noticed there is a dead/stuck pixel on my screen. It shows up white against a black background, but is also detectable against a white background. I can also faintly see a mark there when the display is turned off so I have a feeling it was caused by physical damage. I want to bring it in to get it fixed but my warranty is now 2-3 weeks expired. There is a 90-day guarantee on the speaker "repair" I had done, but obviously that is not directly related to the screen.
I realize it's hard to believe screen issues would arise from a speaker repair. However, I think it is at least possible that they damaged the screen when they took the computer apart. I've had this computer for a year without any issues; I definitely would have noticed the pixel had it been there before--I do alot of programming with a black background. It's quite a coincidence that I first notice a problem right after I bring it in to apple.
Do you think I can bring it in and get it repaired? Should I call AppleCare? Also, if they deny me the repair, is it too late to extend AppleCare for another year? Thanks!
(the display is Samsung, for those who are wondering)

We are just users such as you so our opinions don't really matter. Do bring the MBP in to the store and have a talk with a decision maker. Sometimes good things happen but don't expect that to be the case.
Regarding Apple care, you are too late. It must be purchased prior to the expiration of the one year warranty.
Ciao.

Dead or stuck pixels?

Hi
I got my MBP a week ago and I didn't notice anything worng with it, except for the known things like "whine" and "heat", but I'm OK with that.
Today I noticed a display issue, something like a dead pixel or whatever It might be called. I could have been there before, but I'm pretty sure I would have noticed it as I can see it pretty clearly now when browsing the net.
I ran a pixel checker and saw another one, the same appearance! But a bit further away so I don't notice it when surfing.
I have an external TFT monitor which also has one of these, the same kind. I Googled a bit now but I'm not sure if it's a stuck or a dead pixel. Stuck pixels seem to be fixable with some flashing movies, if you're lucky, but shouldn't be used too much as they might cause new stuck pixels (?).
Anyway, I read DEAD pixels are black. My pixels are not black, but they aren't of the same color all the time. Depending on the angle I view them from, they "blink"/change color from red,green,blue, they aren't the same all the time.
Do I have stuck or dead pixels?
Thanks!
edit: But it looks like a black little spot when I look at it straight in front with a, say, red, green or blue background behind it. I mean that there isn't any idea to run the pixel fixer if I know that they are dead.

You, know, I think I just fixed it :P
I read a lot on different sites just what you wrote here, but I wanted to make sure I had stuck and not dead pixels!
Anyway, I ran the little movie file which flashed colors and then I just rubbed the spot with my finger... they both disappeared! Took less than 10 seconds! Using both the methods at the same time did the trick for me (in the short time I tried it anyway!)
Would be pretty cool if my "dead" pixel on my external monitor disappeared also... Hehe, I've lived with that one over a year
Thanks for the fast reply!

Dead / Stuck Pixels MBA

Hi everyone,
Just got a brand new MBA from JB Hi Fi. Much to my disappoinment the moment I turned it on there were a clump of dead or stuck pixels just to the right of the middle of my screen. Now I'm no expert on the size of a single pixel, but this is certianly noticable and may indeed be more than one together.
I took my MBA back to JBs and they currently hold it there. They told me that they had to wait until Monday morning to call Apple to see if I can get a replacement.
In the meantime, can anyone tell me the chances of getting a new MBA? I haven't even had it for 24 hours! Repair work is not an option for me because last time I had an Apple laptop repaired it came back all scratched up. Besides, surely since it was defective out of the box it can warrant replacement.
Has anyone experienced pixel problems like this? How did you go with Apple?
What steps should I be taking right now?
Thanks I really appreciate any and all comments on this. I'm really quite anrgy that this has happened!
Ed.

I have had the same thing occur to me in the past with an Apple laptop (note: it occurs with all laptops since they use common components)... With my bad luck, it has occured to me twice now -- with both a new (within the return period), and another time almost a year later within the AppleCare period. The first one was a dead pixel, but I had another defect also with the case. Both times, I was fortunate they helped me out, and I will explain my situation below.
I would think that if it is brand new, you should return it and demand a new replacement computer (or all of your money back). You should not have to get it "repaired" which essentially makes it a "refurbished" computer. Even if it is only one or a few pixels, it should not do this within 24 hrs.
Now if it were outside the return period (such as more than 14 days), you may have a more difficult time. There apparently is an acceptable number of pixels allowed, but this all depends on the circumstances. I had a stuck bright red pixel almost dead center and some grey areas elsewhere... not good at all, and especially when showing my work to clients. I had it replaced under AppleCare.
I hope this helps you out, and I would also call up Apple and let them know. If you are not satisfied with the vendor, you might be able to work something out with Apple directly. Good luck.

Stuck pixel, what to do? are you experienced?

Hi, after 4 months of ownership my w520 developed a stuck pixel.
No big issue because mine is FHD and I can barely see it under normal conditions, at least is not in the middle.
I searched and read that stuck pixel sometime can be "fixed". I've read about different solutions, a "color flashing software" that you're supposed to run for some time, someone fixed with "pressure and turn on" method and someone else used the "tapping" method...
Well, if it was an acer entry level (no offence) I would try that and other methods and pretty violently too but on a w520 i'm a little more gently lol.
As now I tried one of these "flashing software" where you have a small "flashing area" that you move over the stuck pixel and leave it flashing, but until now the pixel is stuck.
I tried with easy pressure over the pixel area shutting on and off the screen, but pixel is there, stuck.
i tried light tapping and nothing.
Pixel is stuck to red, so it's not dead.
Are they always fixable? have you experience fixing one on FHD screen or other thinkpads?
(yes I know Lenovo's pixel policy will not cover one pixel)

with white background (as bios screen) it's stuck to red, with black background it's stuck to light blue.

Are these dead/stuck pixels? Glass damage? Or something else?

Can't quite figure out what this is. Are they stuck pixels? Dead pixels? Eyelash? Damaged glass? Something else?
Because of the glass pane between the display and the screen, I can't tell how much the glass, if any, is potentially refracting colors of the pixel below. I've tried running stuck pixel software to no avail. The display is out of warranty, so it would cost $400 for Apple to fix. But if it is simply in between the glass and the display, maybe there is a cheaper fix.
It is only visible on a lighter background. On a black background, it is not visible at all. I would assume if they were stuck pixels, they would remain visible on a black background. But if it is a small crack in the glass, it would make sense that it would only be visible under certain conditions.
Please let me know your thoughts.

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
