Modern television screens consist of numerous tiny pixels that light up and change colors to form images. When one is dead, it always remains dark (black). This interferes with the viewing experience in an annoying way, but you may be able to have it repaired or at least stop the problem from getting worse.
Your Samsung TV could have dead pixels because a portion of the screen wasn’t manufactured correctly. Another possibility is that the television was accidentally damaged before or after you began using it. A few other theories exist but have not been verified.
If you’d like to learn more about dead pixels and find out what you can do about them, please continue reading.
You’ll discover how to check your entire screen for pixels that don’t work. This article also discusses prevention as well as warranties and return policies.
Why does my Samsung TV have dead pixels?
Unfortunately, the most likely reason why your TV has dead pixels is that the pixel has broken. There is not really much you can do about it other than seeing if you can get it repaired.
This problem usually exists because electrical power isn’t reaching an individual pixel. The connection might have been broken or may have never been made.
Even if no manufacturing defects exist, your television could’ve been damaged in transit to your home or the store where you bought it. Such problems are normally evident as soon as you begin watching the TV.
It’s also possible that you or a previous owner accidentally dropped the TV set or knocked it over. A natural disaster such as an earthquake could have the same effect.
Additionally, there’s a theory that black spots may appear if you display the same picture on your television for many hours.
How to prevent dead pixels
Place the TV in a location where you’re unlikely to bump into it. Put it on a sturdy piece of furniture or wall mount. Keep pets and young kids away from the television.
Use the original Samsung box and packing materials to safely move and store this equipment. When transporting your TV to a new home in a vehicle, ensure that it’s fully secured and protected.
Can you fix dead pixels on Samsung TV?
Sadly, it’s usually not possible to repair them on your own. You can find various techniques and products on the internet, but none of them appear to be reliably effective.
If your screen actually has stuck pixels that light up and always stay a single color, you may be able to fix them using certain methods or apps.
Some people claim that dead pixels have eventually “come back to life” without being repaired.
However, many technology experts say it’s impossible. You could try adjusting the brightness and contrast in a way that reduces the visibility of black spots.
Unfortunately, Samsung’s latest warranties typically don’t cover this screen defect. Some electronics stores can repair televisions for a fee.
Do retailers cover dead pixels on Samsung TVs?
Certain stores will let you return or exchange them during the normal return period. For example, Best Buy generally allows customers to bring back units with at least three dead or stuck pixels.
Newegg permits returns of TVs with any number of dead pixels. You may qualify for additional protection if you bought extended coverage or have joined a retailer’s membership program.
How to test for dead pixels on Samsung TV
You can accomplish this by displaying a solid bright color across the entire screen.
If you’re able to access the internet on your TV or a computer that’s connected to it, you could navigate to a dead-pixel testing website or video.
Another option is to run the Windows Paint application in “Accessories” under “All Programs” on the computer’s Start menu. Leave the “canvas” blank, and press F11 for full-screen viewing.
Count how many tiny black spots you see. Larger black areas indicate that multiple adjacent pixels have failed. If you see spots of the wrong color, the pixels are stuck.
