Dead pixel surrounded by white spots

I have had my Powerbook G4 for about 3 months and have noticed a dead black pixel in the lower, center portion of the screen. I believe this deadpixel is abnormal because a cluster of white light surrounds it making the area appear larger than just the dead pixel (the white cluster is most apparent under greens, blues, dark colours). The white spot surrounding the dead pixel appears to be increasing in intensity and size.
Does anyone familiar with this problem? Could the dead pixel be affecting the pixels surrounding it? Will Apple replace my screen?

Hi Denise & Welcome to Apple Discussions --
Take a look at the following Apple Kbase article, if you haven't already: http://docs.info.apple.com/article.html?artnum=22194
You also might find this web page to be of interest: http://forum.notebookreview.com/showthread.php?t=11976
Sometimes, you can get rid of dead pixels by very, very gently massaging the are of the dead pixel with your thumb -- this doesn't always work, of course and you need to rub very, very gently.
Bottom line: if you're unhappy with how the screen looks because of the dead pixel(s), you need to take it in to have Apple look at it to determine what can be done. No one on here can make that call or can accurately predict what Apple will say.
Good luck.

PS You may have heard that some PowerBooks suffered from a known problem of faint white spots in the display, see http://docs.info.apple.com/article.html?artnum=86632 But, as you can see, this issue was with PowerBooks produced a while back (and at least 2 or 3 revisions ago, and to the best of my knowledge the problem has been resolved.

  • A White Dead Pixel

    My almost a month old retina macbook pro has a single white dead or stuck pixel on right top side of screen. It is very noticeable during movies and photoshop. What is apple policy on a single dead pixel. Is white dead or stuck pixel? My old non retina MBP had black dead pixel. Any advice would be great. I am from nepal it may take few weeks to get it replaced even if it is replace in the first place. So i want to know single dead pixel on 3 and half week macbook pro is worth sending to have it checked for possible replacement thanks in advance.

    yes i think you should do it sand it for a replacement ,because its the screen it may get worse in do time ,the best this is to sand it back for a replacement screen  ,its best to be save then sorry ,and you should do  back up to just in case you  never no they may do full resat there on it

  • Dead pixel spot

    I just bought an iPod Nano a week ago.
    I imported all the CD's I had into iTunes, and when I connected the iPod to the computer (Windows XP), a black spot the size of a laser pointer appeared.
    I went back to the Apple store from where I made the purchase, but they told me that this happened because water got inside, and they could not help me.
    I only took the iPod out of the case when I connected it to the computer, and it did not come in contact with water.
    Could someone help? It was supposed to be a birthday present.

    Sounds like you've got dead pixels. Just call support, and tell them your situation. They generally won't replace anything for 1 dead pixel, but for a spot the size of a laser pointer, they should. Especially with the size of the nano's screen. Also, the water(possibly) could have gotten in during shipping. Just tell the support guys everything.

  • How to cope with a dead pixel

    Yes, I know, there's no fix for a dead pixel (is there?), and there are lots of maybe-fixes for a "stuck" pixel. Well, I have a dead pixel, super-dead, in a really terrible place (the lower right quadrant, just a tad above where, say, the iTunes ministore would be). I'm stuck with it. I can't do anything to get it fixed or replaced (can I?), so my question to the community is about dealing with it. How does one cope with something so aggravating? Are there some tweaks one can do to make, say, white web pages reverse their colors so the pixel is not as apparent? Are there other methods to get rid of it or make it less obvious? I'm going mad. Someone help. <<br>

    Well , I do understand how crazy it can drive you when a pixel is dead. Everything was fine on my MB then about a month in I noticed a pixel that was dead, I too looked at every topic I could find on the subject, nothing helped. So I took my MB into my local Apple Store, they sent it off to repair. Of course Apple did not fix because "One pixel is not considered enough of a problem to repair". So the Apple Store actually ordered me a new screen and replaced it for free.
    I was very happy until I turned on the computer at the A.S. and once again it had a dead pixel in a different spot. they said that there was nothing they could do about it. They would not replace it again because it would screw up their store budget. So I'm learning to deal with it. Believe me it really *****, I'm a perfectionist at it really bugs me to see this flaw. Other than that my MB is great and I love it. Good Luck!

  • Policy and best way to get dead pixels fixed.

    I have an iPhone 4 and I have 1 or 2 dead pixels surrounded by about 20 dark pixels. I was wondering if the default warranty would cover this or if I'm stuck with it. Overall the dead pixel isn't that noticeable but the dark cloud around it is really annoying. Thanks for any help you cann offer.

    Hi,
    Don't know about the cost... but here is the Link to the Apple Store in Brisbane...

    You can Call them and/or Make an appointment at the Genius Bar and they will advise you...

  • Ipad 1 dead pixels

    i've notice about a year ago that my ipad 1st gen had a dead pixel at the top of the screen, i've read on the internet that apple will replace my ipad only if i have 3 dead pixels, today i've noticed another 2 dead pixels which can be spotted when the ipad is hold orizontally and you try to see the screen.
    i've got 2 questions:
    1.they will replace my ipad with a 2nd gen ipad?
    2.is it worthing to change it, or the dead pixels isn't such a big problem.
    Thanks for your time.

  • White dot (not dead pixel) on external LCD monitor.

    Hi all,
    I recently noticed a strange situation. I've owned a MacBook Pro 13" since October, and usually run it with an external Samsung T260 LCD monitor by MiniDP to DVI. I run the monitor at its full resolution of 1920x1200.
    When I arrange the monitors so that the Samsung is on top of my MBP, there is a white dot about the size of a pixel approximately 3 inches from the left and 1/2 inch from the bottom of the screen. I thought it was a dead pixel, but when I move the external monitor to be on the left of the MBP, the white dot moves to 3 inches from the top and 1/2 inch from the right.
    * The white dot does not appear when I arrange the monitors in any other configuration.
    * The white dot appears when using MiniDP to VGA adapter as well.
    * When I zoom using the modifer key+scroll method, the white dot grows bigger.
    I've tried using the JScreenFix applet, but as I said, it doesn't look like a dead pixel.
    Can anyone offer any other suggestions, that may involved poking around in the Video RAM space?
    Thanks,
    -Tony

    Hi all,
    Just returning to provide more information:
    While playing around with my screen layouts, I found that the white dot is actually part of the menu bar graphic. I arranged my monitors and captured the screen to show the placement of the dot.

    I hope Apple is able to fix this in the next SW update.

  • White Specs and 1 Dead Pixel

    Hi everyone,
    I'm not sure if anyone else is experiencing this but I have a week 36 iPod, without any of the audio or negative black issues but instead with tiny white specs that appear and disappear when I move the iPod in different angles. These white specs can only be seen on a black background and there are so many of them that I couldnt even count them. They also appear to be randomly appearing so they are very difficult to count.
    The one dead pixel is to the right of the screen and is green. I am not too fussed about this but I wondered if any of you have the same issue?
    I have looked at my iPod video and I do not seem to have the same white spec issues.
    Here are some screens of my iPod touch video quality:

    I have the same issue as you do. I think the technical word for this problem is a stuck pixel. In my case they are green and white and lots of them. Turn your brightness to full and then test you screen with a black background, and while you are at it show it also to a genius. I am sure they would replace it, please let us know how things went.

  • I've got a dead pixel (white) in the middle of my Macbook-pro retina display.

    I've got a dead pixel (white) in the middle of my Macbook-pro retina display, what to do?
    Just bought it a a month ago, and it's really anoying me!
    Harmen

    Take it back in and gently but firmly try to persuade a senior supervisor to authorize a replacement. Had it been stuck on black, would have been easier on the persuasion, but you may get lucky.

  • There is a small white light in the retina display on my ipad 3. Is this a dead pixel/light leak and how do I fix it? (Located at the bottom left side between home button and left corner)

  • White IPAD2 64 3G - White dot underneath Screen, Dead pixel

    Hi,
    I am residing in Stockholm,Sweden. i bought my ipad2 the day it was released here on march 25th.
    3 days back, i noticed a dead pixel, which was visible while using safari. i have downloaded the pixfix app to confirm the dead pixel. the pixifix conducts few tests by changing the colors and the dead pixel was visible as black.
    how ever, i switched off the ipad and to my astonishment, i can see a small white dust/mark underneath the glass with no visible scratches or anything. since i take care of my IPAD very well.
    i had the same problem with my first generation ipad after few months which apple replaced it.
    since then, i called apple in stockholm, and they directed me to go to Digitall Inn their premium reseller/support. this is the place I bought my ipad2. i went in there and the support guy(daniel) try arguing that it is not a dead pixel instead scratch. and he had no answer when i showed him the white dust/mark. he said one of their technicians will analyze and get back. this was happening last saturday.
    its been two days since they never updated/called me, i called up digital inn and i was told that, they will take a photograph of the issues and send to apple. it will take 3 more days to get an udpate from apple. and he also offered me to take the ipad2 back or keep it in store. i told them i need a solution to this and till then they can keep it.
    i am seriously surprised by the kind of support i am getting from digital inn. i have invested a lot in this device, and when it is defective, i dont understand the kind of support i am getting from this premium resller
    Dear Apple support,
    please help me to resolve this issue of ipad2.
    Subramoniam AB

    Yesterday afternoon at 1.01 pm, got a call from  the technician at digital inn, and he told me that apple had indeed sent a new ipad for me and i could go there to collect it.
    well, i was thrilled by the sudden turnarround of events and i rushed from my place of work to get it.
    so finally a brand new one, i beilive no refurbished stuff. bought a belkin verve folio from webhallen which is next to digitall inn in stockholm.
    so glad that, go every thing fast rather than after 2-3 weeks.
    hi thenextbutton.
    in stockholm, sweden, they dont have any apple stores but we have to go through thier premium resellers who has stores similar to apple store. hence for any issues, we are left with no choice but work with these folks. digitall inn is one of thier premium reseller.

  • 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.

  • Camileo S10 - White Dead Pixel in HD modes

    I purchased an S10 yesterday and have noticed a massive problem. When I shoot in any HD mode there is a dead (white) pixel that floats over the footage mid screen.
    I would like clarification on this issue as quickly as possible otherwise it's back to the shop for a other camera?
    Many Thanks...

    Hi
    Do you have this white pixel only on the monitor or on the recorded videos?
    The LCD displays could have 1 or 2 dead pixels. Thats normal.
    But if you have this dead pixel on the recorded videos you should contact the nearest authorized service provider. It seems that there is something wrong with the picture sensor

  • Dead Pixels/Dark spot?

    I was just working on some homework on my macbook pro and all the sudden I noticed this dark spot/dead pixel in the right center of my screen. At first I thought my screen just got dirty, but that was not the case. Can anyone tell me what this is... and if apple will cover this?

    ****... well here is the weird thing... there hasn't been any sort of blunt force or anything even close to that, that happened to my laptop. I make sure that if I ever take it out that it is gentally set down. I have the laptop sleeve as well as a laptop bag.
    The only thing I can think of is that maybe when I sent my Macbook Pro into Apple to get the logic board replaced that somehow some sort of pressure was applied to the screen to cause this. Would the problem that I'm having appear several days/weeks/months after the actual day when some sort of pressure is applied to the screen? I think this whole dead pixel or whatever it is happened sometime within the past 3-4 days in which my laptop has been sitting here on my desk with nothing stacked on top of it.

  • Dark spot (not sure if it is a dead pixel).

    I have a dark spot in my menu bar. I'm not sure if it is a dead pixel... it almost look like if there is dust inside my screen. Do you have something to recommend to take it away?

    If you have not already solved your monitors problem, you can try PiXel Check, to see if you have any dead or stuck pixels.
