Macbook Pro Dead Pixel
The dead pixel on the MacBook pro may be due to the reason that it is not getting enough energy. You can replace the entire display unit in order to fix the dead pixel issue. If it is under warranty then it will be covered for free.
This is a simple test designed to facilitate the detection of dead pixels on an LCD display (pixels which are stuck ON or stuck OFF) by showing a set of pages with a consistent background colour to provide contrast. Once you run a Mac Dead Pixel Test, you are presented with a series of colors.
If a pixel is not blocked by your monitor, you can wipe your screen clean with a soft cloth, and then head over to Dead Pixels Test website to see if you can fix it on your own. There is a possibility that you may be able to fix a pixel that is stuck by massaging the screen or playing a video that has a bouncy color. You could potentially fix the stuck pixel using the fixes below, massaging the area, waiting it out, turning the display off, or viewing the stuck pixel video.
If you are using a monitor, you can easily check your display for dead or locked pixels using several websites. InjuredPixels allows you to easily check faulty pixels on your LCD display (hot, dead, or stuck). InjuredPixels can be used to check for new LCD monitors before purchase, or already purchased monitors in the warranty period (since you may receive a replacement according to a manufacturers policy regarding dead pixels).
Using Dead Pixel Test & Fix (Android) App, you can test and fix dead or stuck pixels on an Android device. You can use PixelHealer to repair dead, locked, or warm pixels on LCD or TFT screens, desktop monitors, laptops, or tablets. PixelHealer uses an already tested concept, flashing RGB colors over a dead or stuck pixel will resurrect it.

Selling is a good way of recycling a product to be used in places where a dead or stuck pixel is not going to be such a huge problem, like in industrial processes or in server rooms where graphics quality is not a major concern. Using third-party tools, you can blink a pixel with different colors to help make it look better after being stuck or dead for some time.

If you are seeing colored or white pixels, you may have the ability to repair them. If so, launch a repair, which quickly blinks the whole screen to a mixture of black, white, and primary colored pixels. JScreenFix will load up the black browser window with the square flashing pixels.
If your pixels are showing a particular color besides black, or changing colors depending on your background, then they are probably stuck. Because a stuck pixel is always-on, it usually appears as a bright, permanent spot on the screen, and is either red, green, blue, or white. A hot pixel is so because the electrodes behind it let in all the light, no matter what is on the screen.
Each pixel is made up of three different electrodes, one for each color. Each subpixel has its own transistor, which is responsible for turning on or off that subpixel. Brighter or darker sub-pixels may arise in LCD monitor panel manufacturing, but they will not impact LCD monitor function.
Using Screen Utility, you can check to see if there are dead or flawed pixels in the display. If a defect does not affect a single pixel, though, or it is simply causing a great deal of distress, then you could always swap out the monitor. Even if you try to fix the issue, you may still discover that there is one pixel that is dead on the screen; it is probably dead in your case, which will require replacing the screen. If a pixel continues to degrade in your screen, then you need to replace it.
Most display manufacturers require a minimum amount of dead pixels before you can exchange the screen. The best way to repair a dead pixel is to contact the manufacturer of your LCD screen to find out if they will replace your screen.

Dead pixels caused by manufacturing defects, on the other hand, are more serious than dead pixels because it indicates the screen needs replacing. Dead pixels may result from alignment errors, incorrectly cut components, or even dust particles landing on an LCDs matrix may lead to dead pixels. Used in many of Apples products, including the Cinema Display, MacBooks, and MacBook Pros, as well as in iPhones, iPod Touch, and iPads, LCD screens may experience pixel anomalies. If you have not noticed unusual spots on your screen (blacks, or any color), you are probably not having a problem with dead or blocked pixels.
Soft fabric or a blunt object should apply pressure on any pixels that are trapped or dead. Gently press down on stuck pixels using the blunt object and a soft cloth.
You may want to try the hand-held method, which involves wiping a damp cloth over the pixel or using a sharp yet soft object such as a rubber/eraser on the end of a pencil. Be cautious using this method, as you run the risk of scraping the screen, and you may also end up damaging multiple pixels.
If you cannot locate any dead pixels, turn the phone to landscape and run a full-screen site. If the problem pixel is dead, it should appear as a small black rectangle.
If your screen is not covered by a warranty, and you did not buy AppleCare when you purchased the phone, you will need to pay for your screen to be replaced. A dead pixel is an issue that is more or less permanent, and does not get better with time. If your retina display is under warranty, it will either be covered at no charge, or else repair would be pretty expensive. Pixel defects can be frustrating and distracting, but Nintendo has indicated they are not going to replace those tablets under warranty anytime soon. The dead-pixel policy is the third internal document from Apples support department leaked in the last week to BGR, the first was about whether you could transfer your AppleCare warranty to new purchases, and the second was about display issues on some new MacBook Air models.
Note that most manufacturers specify the maximum amount of allowed dead pixels at a given resolution, and a warranty does not kick in until your display crosses this threshold. DeadPix is an app that can help you correct pixels that are stuck to your screen. PixelHealer is likely to work with a stuck pixel showing signs of life, rather than a dead pixel which might remain unresponsive, but there is a possibility that PixelHealer could solve either, so try out this DeadPix fix no matter how you are dealing with the wounded pixel.
Can you really fix a dead pixel?
Press down on the spot where the trapped pixel is located. Avoid applying pressure elsewhere to prevent the formation of further stuck pixels. Your computer and screen should be turned on while exerting pressure. Once pressure is released, the trapped pixel should disappear.
What causes dead pixels on MacBook?
It is often the result of a foreign object embedded in the display or on the front surface of the glass panel that causes pixel anomalies. There are often irregular shapes to foreign materials, and they are usually most noticeable against a white background as they can appear to take place on a white background.
Can you really fix a dead pixel?
Put pressure on the area where the pixel is stuck. Make sure you only push elsewhere since this may cause more stuck pixels. Press firmly on your computer’s screen and turn it on while you apply pressure. Removing the stuck pixel should be no problem once you release the tension.
