Samsung TV Dead Pixel

Researchers lack specific data on warranty issues for Samsung TVs with dead pixels, but note some general trends.

  1. A dead pixel, appearing as a small dot about 4 inches from the edge of your screen, might qualify for a warranty claim.
  2. Samsung’s warranty may cover a dead pixel on your TV. Whether or not you can claim it depends on where that pixel is on the screen. There are cases where 1-2 dots can be a warranty case, but only for some screen diagonals.

In any such case, contact Samsung technical support to clarify the situation. The necessary phone numbers are in the TV’s user manual or official website.

Tolerances For Dead Pixels

The ISO 9241 specification outlines the acceptable tolerances for dead pixels in video matrix displays. ISO 9241-307 outlines four distinct screen quality classes based on the adequate number of dead pixels.

This standard presents four classes of defective pixels per million in LCD panels:

  1. Class 0 panels are completely defect-free, including no broken pixels or subpixels.
  2. Class 1 panels allow any or all types of defects:
    • One pixel that remains consistently illuminated, appearing “white.”
    • One permanently off pixel, also known as a “black” pixel.
    • Two individual subpixels, either bright or dark.
    • 3 to 5 “white” or “black” subpixels (depending on the number of each)
  3. Class 2 panels allow any or all types of defects:
    • 2 completely light
    • 2 completely dark
    • Use 5 to 10 light or dark subpixels, single or double, but no more than five can be bright (“white”).
  4. Class 3 panels allow any or all kinds of defects:
    • Five radiant pixels.
    • 15 entirely black pixels
    • 50 single or double subpixels.

Many brands label their high-quality LCD screens as Class 0, meaning “totally defect-free.”

 TV Dead Pixel

Broken pixels that don’t show the right color or stay black or white can degrade your TV’s picture quality.

A broken pixel on the TV won’t respond to any control signals. So, you end up with this annoying black or white dot that won’t go away, or sometimes it sticks to one color.

There are three types: stuck (one color), dead (black or white), and hot (too bright with incorrect color).

In the past, Samsung did not consider broken pixels as a warranty case. Today, for 2024, the company’s warranty varies from country to country and from display to display. Warranties typically apply only when a minimum number of broken pixels are close together on a 4K screen.

The warranty depends on the screen’s technology (LCD, OLED, QLED) and resolution, whether 4K, 8K, or 1080p.

Understand the warranty for your TV and check the documentation for pixel defect coverage.

The “dead pixels” policy doesn’t cover every situation. Samsung’s warranty does not cover pixel problems resulting from user damage, accidents, or modifications to the TV.

If you find bad pixels on your TV screen, check the warranty, visit Samsung’s website, and contact customer support. You need to find out if your TV is under warranty. If yes, follow the advice of the support service, and they will help you solve your problem with dead pixels on your TV.

Attention to broken pixels on displays has always been a priority and taken seriously. Therefore, even screens with a single broken pixel are considered defective. However, not all manufacturers recognize it as a warranty case. You can change the TV before you buy it in the store. What exactly qualifies as a warranty case? Is the TV already at home? It would help if you asked about this when you buy a Samsung TV.

Pixels that have successfully passed factory tests may fail during the TV’s operation. The manufacturer must guarantee the matrix’s performance for the period specified by standards.

Samsung TV Pixel Policy

Each company has its own policy regarding ad pixels. Many manufacturers determine the number of faulty pixels that qualify for a warranty claim.

Samsung perceives its displays as flawless. However, the company lacks a clear policy for annoying color dots on the screen, which impacts warranty replacements. These conditions are subject to change over time. The rules explain how many subpixels can be broken and show where these broken subpixels are on the screen. They also address stuck crystals in cells and burnt-out control circuits for dots, which impact the warranty policy.

You can still hope for a warranty from the seller, but you need to find out when buying a Samsung TV.

Why Are There Dead Pixels?

The cause of the appearance of broken pixels on the matrix of a color TV may be:

  1. Overheating or overcooling of the device. High or low temperatures cause sub-pixels to harden and lose their ability to move within the liquid crystals.
  2. Ambient humidity. Elevated humidity poses a significant risk to the integrity of the LCD substrate. Moisture on the matrix creates glowing areas or white dots on the display.
  3. Voltage spikes. A problem in the electric network can lead to transistor failure. When this happens, the energy going to the RGB matrix can cause the sub-pixels to get stuck in one position.
  4. Breach of production protocols. Factory defects mainly arise from three factors: repeated washing, drying, and lithography of matrices. The slightest non-compliance with technological processes leads to defects in the final product.
  5. Also, the matrix can be damaged during the careless transportation of the TV set to the point of sale. Despite the strong fixation in the substrate, the liquid crystals are very sensitive to sharp mechanical jolts.

Let’s familiarize ourselves with the 2025 TV buying guide.

Dead and stuck pixels are problems that can occur on digital displays such as LCD screens. A dead pixel is permanently disabled and always appears as a black dot. It occurs when the transistor that powers the pixel fails.

Dead pixels cannot be fixed and usually require replacing the entire screen.

On the other hand, a stuck pixel is a pixel that is stuck on one color, usually red, green, or blue.

Stuck pixels can sometimes be fixed using pixel correction software or gently massaging the area around the stuck pixel.

Use software that shows various colors on the screen to check for dead or stuck pixels. It is probably dead if the pixel remains black regardless of the color displayed. If it shows one color, no matter what, it’s probably stuck.

So, it’s good to remember that dead or stuck pixels can be annoying. Many brands have rules regarding the number of faulty pixels required for warranty repair or replacement.

The bottom line is that dead pixels are usually black (sometimes white). Stuck pixels typically show up as a bright dot on your screen. This happens when one, two, or all three subpixels of the primary color stay lit up all the time. If the pixel in question is white, both are possible.

F.A.Q.

Unfortunately, you can't resurrect dead pixels. Once they are damaged, they stay like that for good. If too many pixels go bad and the set is still under warranty, file a claim with the manufacturer in writing, stating that the set has too many dead pixels.

Your display can be replaced during the duration of the limited warranty period if the number of dead pixels is greater than the allowable number.
