Adjusting the TV picture settings can fix the bright spots problem. Many other solutions can also help you fix this issue. But before heading toward solutions, it is essential to understand the potential causes of the bright spots on your Samsung TV screen.  

So, let’s start with the reason that causes the bright spot issue on the screen. Then, I will explain the effective solution to your problem. 

Bright Spots On Samsung TV Screen? 5 Possible Reasons

How to fix Bright spots on Samsung TV

Why is there a bright spot or ghosting screen on my Samsung TV? Depending on the model, various reasons cause the Bright Spots on the Samsung TV screen. 

The five most common reasons that cause bright spots on every Samsung TV model are essential to know. Therefore, I will describe these 5 possible reasons for the Bright spots on the Samsung TV screen.

1. Dislodged LED Diffuser Lens

Dislodged LED diffuser lenses on the Samsung TV screen cause bright spots due to uneven backlight distribution. Modern smart TVs have backlights with LED bulbs.

Each bulb is sheltered with a diffuser lens to distribute the bright lights from the bulbs equally on the TV Screen. When the LED diffuser lenses become dislodged, they spread the light on the screen unevenly. 

As a result, it creates concentrated and brighter spots on the screen.

Slightly tilt your TV from both sides; if you hear some noise, it means the diffuse lenses got unglued and fell. Fixing the defective LED diffuser lenses can fix the Bright spots on the Samsung Screen issue.

Additional information: 

The LED diffuser lenses shelter the bright light bulbs on the backlight. These lenses spread the bulb’s light equally on the TV screen. When these lenses dislodge, they reflect light directly onto the TV screen and create white spots.

These white spots are known as “orbs.” The lenses can dislodge when the adhesive attached to the backlight panel gets unglued or dry. If you notice 0.5-2 inch circular white spots on your Samsung TV, it indicates dislodged LED diffused Lenses.

2. Pressure Damage

Pressure damage results in Bright spots on a Samsung TV Screen due to the physical impact on the display’s layers. TV screens are made of liquid crystals and other components that can be affected by pressure damage. 

The pressure damage disrupts the arrangement of the liquid crystals and other materials. The disrupted liquid crystals lead to variations in Screen pixel behavior. 

The changed pixel behavior causes the pixels to get stuck in a position where one or more pixels emit more light than the surrounding pixels. These damaged and stuck pixels appear as Bright spots on the Samsung TV screen. 

3. Faulty LED Backlights

LED backlights in Samsung TV screens provide illumination to allow efficient picture visualization on the screen. The screen gets inconsistent illumination when there is an issue with the LED backlights

Ultimately, the inconsistent illumination leads to Bright spots on the Samsung TV screen. These spots can also appear as concentrated white patches on the TV screen. 

These spots or patches affect the picture quality and user experience. Repairing or replacing the Fualty LEDs will resolve the bright spots issue. 

4. Defective Pixels

Sometimes the screen pixels get “stuck” in the on or off position on the screen. They emit a higher and more constant brightness than the surrounding pixels. These stuck pixels result in bright spots on the Samsung TV screen. 

Any electrical difficulty, physical damage, or manufacturing defect can cause stuck pixels. The quick fix to this problem is to repair or replace the screen. If your TV’s warranty has not ended yet, contact Samsung customer support to get free repair or replacement services. 

5. Faulty Panel

The TV panel can malfunction due to defective pixels or sub-pixels that get stuck in the “on” position, emit excessive light, and cause bright spots. The panel can also be damaged due to backlight bleeding. 

During blacklight bleeding, the TV’s blacklight shines unevenly and causes certain areas to be brighter than the surroundings. Moreover, damaged or faulty LCD layers or OLED technology can result in faulty panels. These faulty panels lead to bright spots on Samsung TV screens.
