My Screen is filled with green and blue dots- pixels dead?

Hi I have had ben Macbook for 2 years with very few issues.
I noticed today that when I switched on my screen is filled with waves of green, some blue colours through the desktop background. Is the screen knackered or can this be resolved?
Many thanks in advance

Somehow, you've managed to post in the new 24" Cinema Display section. You'll probably have better luck with an answer in the Macbook section. Cheers.

Green and blue dots around all the screen

I have noticed that green and blue dots appear around the screen of my tablet, i have send to sony service, can anyone have this issue too? it has only 1 month of use...

Same problem on my tablet (second one, first i already replaced) green dots all over screen.Two months of use.
Model is sgp511 b2/b 14w16. Sony (if any of you guys reading this) please do something about that, your tablet is not cheap to have this problems.

Screen covered with green and blue pixels (visible on dark colors)

Hello,
I have this tablet since beginning of April, and since few days I've noticed the little dots on the top of the screen.
From far away it looks like dust behind the screen, but by having a closer look, it's like pixels that stay green and blue when the rest of the image is dark.It's very visible when I'm using the tablet with no lights around me. i've tried to restart the tablet, and even when It's loading with the SONY sign, I have that! what should I do ? Did people had that issue before ?
(BTW, The screen is also unresponsive when plugged to charge)

I encounter the same problem. I bought my Z2 tablet 16GB from the Singapore Sony Store. I got it for one month and the same pixel problem appeared. I send it in for servicing at the Singapore Sony care centre at 313 somerset outlet.. One week went by and nothing happened. The service was bad, no reply from the customer care or technician. They gave me a website so i can check the status of the servicing but all it shown on the page was pending.. one full week and still pending. I had to call them once and asked them what happened, the Sony personal over the line could only say they can check and get back to me. The next day i called again to check if any technician has even start and immediately right after that they called me to go down to collect. Turn out they are giving me a new tablet. And the screen protector was not refund to me as they said that the device was still in the service centre.. had to buy a new one for myself. Such a disappointment in the servicing.. and now the current one i am holding as the same freaking problem.. also i notice the corners of the screen has some yellowish hue.

Mac stuck at Gray apple screen that turns red, green and blue.

A month ago I was playing world of warcraft on my powerbook when the entire screen froze up and pixelated. I forced shut down and powered it back up. Now I only get the gray screen with the apple and the spinning wheel. The gray screen changes color to blue, then green then red and lines flicker horizontally up and down my screen. After a minute the little wheel stops spinning. I have tried all of the various resets, booting into safe mode, hooking it up to an external monitor and none of those options worked. I booted into target disk mode and ran checks on my hd and it is fine. If I try to boot from my installer cd the screen just goes gray. Do you think this could be a sign of logic board failure?

Welcome to the Apple discussions.
Sorry to hear about your system. You've done some good troubleshooting, however, I'd suggest you take it to an Apple store or Apple Authorized Service Provider, to get their take. It does sound likely that the logic board has issues. You can find the closest store/provider at http://www.apple.com/buy/locator/service/ . Assuming it is a logic board issue, you can buy and replace it yourself, however, it is very involved. You can see how to do it at http://www.ifixit.com/Guide/Mac/PowerBook-G4-Al-12-Inch/Logic-Board/53/16/

My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. Help?

My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. I have tried several times to get it past this point but tnothing helped.
I have an appointment at the Apple store today, but was wondering : will all of the information and files on my desktop be lost? Or is this a logic board problem?
Any help is much MUCH appricated.

I'm not sure, if you're out of warrenty it'll cost quite a bit for the replacement of the logic board replacement...unless you have apple care. you could ask apple to try and recover your hard drive but i'm not sure.

I updated my iMac to 10.7.3 and about an hour later the screen began to flicker with a gray line on the upper side, and it also flicker green and red small pixel lines all over the screen, mainly green.

I updated my iMac to 10.7.3 and about an hour later the screen began to flicker with a gray line on the upper side, and it also flicker green and red small pixel lines all over the screen, mainly green. The computer froze with these pixels, so I shut it off and restarted it, and there were this green lines everywere. So I turned it off, and the next day I turned it on and it began to work just fine, but suddenly the same thing happened again, and when I restart the computer again there are these green and some red pixels everywere.
I've read 10.7.3 is giving people many problems, but I never saw that it gave one like this. How can I fix this, or what will Apple do to fix this problem they caused me with their update.
Thanks

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

Qosmio F30-117 - green and blue lines on the screen

So my F30-117 has been working well recently until I turned it on and had green and blue lines (sort of like scan lines) overlapping the screen.
I tried to install new drivers from nvidia, but that didn't work, as Vista just picked them up as unknown.
Anyone got a solution? Do you think the graphics card needs to be reseated?
Thanks in advance!
- Shayde Zehetbauer.

You can easy determine what the reason is for this.
Do you know how?
Just connect an external monitor to the notebook and check the picture on it.
If you have the same issue on the external monitor the reason is the graphic card and/or mainboard, if not its an internal display issue.
Check this!
Furthermore you should only use the drivers from Toshiba. The Nvidia drivers dont have an overheat protection so the graphic chip could be damaged. Its on your own risk.
So try to install the drivers from Toshiba.

Green and purple dots on screen (fixed!)

So I had green and purple dots all over the screen of my iMac (10.5.6, intel 24"). The dots would disappear briefly when windows were dragged over them. Green dots appeared on black backgrounds and purple dots appeared on lighter backgrounds (e.g. "about this mac" was really bad). I didn't find the solution anywhere and several people reported needing to replace their hardware. With the help of a technician at Apple, we figure out the fix (in my case).
Here's what didn't work:
- shutting off the machine and unpowering for 15 seconds
- resetting the PRAM
Here's what DID work:
- go to Utilities
- go to Disk Utility
- select Macintosh HD
- press "verify disk permission" (and wait a long long time)
- press "repair disk permission" (and wait a long long time)
- reboot
This fixed it. Apparently errors on disk impact bits in displaying certain things. Who knew.
Anyway, I hope this helps someone else.
Nate

OK. Thanks.
I noticed that when I ran the verify/repair permissions again, it found some, repaired it, and the dots went away again. That would indicate a hardware problem.

Has anyone experienced Labview 8.2 crashing when attempting wire a cluster filled with object and task references?

I am getting a complete shutdown (crash) of Labview 8.2 when placing the wiring tool over a cluster that is filled with task and object references. The crash occurs on all computers I have attempted it on and happens throughout all VIs in all classes that distribute multiple references throughout the VI using a cluster. The entire project I am developing is programmed in GOOP. Has anyone experienced anything like this? I have provided a screen shot of the place where the crash is generated. Let me know if anyone has any insights.

There are several known crashes with LVClasses. One of the easiest
fixes is to load your application into memory and then hit
ctrl+shift+click on the Run arrow of your top-level VI. Then do
File>>Save All. You might also try selecting that wire (with the
selection tool -- use the Tools Palette to explicitly select a tool
other than wiring) and deleting it and then rewiring those terminals.

Why my phone doesn't have that Red Green and Blue circles on camera, I have an iPhone4 v7.1.1

My classmate has an iPhone 4/4s, the camera has Red Green and Blue circles while mine doesn't have that circles.

Does your classmate have an iPhone 4? Or a 4S? There is no such thing as a 4/4S. Even with the same version of iOS, different models may have different features. As far as I know, the live filters are only available on the iPhone 5 and later.

Problem extracting red, green and blue from ColorModel

Hi everyone,
I'm attempting to write a piece of code to extract the red, green and blue components from an image using the ColorModel class. When I attempt to run my code below, I get the following error: Exception in thread "main" java.lang.IllegalArgumentException: More than one component per pixel. Does anyone know how to extract an integer representation of the red in a pixel in order to solve the problem? Here's the code snippet:
public void getRGBValues()
          String imageFilename = new String("C:\\Documents and Settings\\David\\My Documents\\My Pictures\\blue hills1.jpg");
         PlanarImage image = JAI.create("fileload", imageFilename);
         //Get the color model for that particular image
         ColorModel imageColorModel = image.getColorModel();
         //ints to store the appropriate values for each colour component
         int totalRed = 0;
         int totalGreen = 0;
         int totalBlue = 0;
         int averageRed = 0;
         int averageGreen = 0;
         int averageBlue = 0;
         int pixelNumber = 0;
         int pixelCount = 0;
         //Loop to extract the colour values out of each pixel in an image passed into the class
         for(int i = 0; i < image.getWidth(); i++)
              for (int j = 0; j < image.getHeight(); j++)
                   totalRed += imageColorModel.getRed(pixelNumber);
                   totalGreen += imageColorModel.getGreen(pixelNumber);
                   totalBlue += imageColorModel.getBlue(pixelNumber);
                   pixelCount++;
                   pixelNumber++;
              pixelCount++;
              pixelNumber++;
         averageRed = Math.round(totalRed / pixelCount);
          averageGreen = Math.round(totalGreen / pixelCount);
          averageBlue = Math.round(totalBlue / pixelCount);
          System.out.println("Average red is " + averageRed);
          System.out.println("Average green is " + averageGreen);
          System.out.println("Average blue is " + averageBlue);
}

You are misunderstanding the ColorModel methods. The color model can translate between colors and pixels, but it doesn't know or hold pixel data.
I don't know the JAI, but if you use J2SE classes like BufferedImage, this is easy to do:
BufferedImage im = ImageIO.read(input);
int argb = im.getRGB(x, y);
int r = 0xff & (argb>>16);
int g = 0xff & (argb >>8);
int b = 0xff & argb;
