How to Fix White Spots on Samsung TV?

With several brilliant TV series with excellent picture quality, elegant design, and outstanding performance, Samsung TVs have dominated the global market share for over 15 years. However, just like any other TV, users report the appearance of White Spots on Samsung TV screens after a year or two of the purchase.

White spots on the screen will ruin your TV-watching experience because these spots remain there whenever you play any content on the TV. These patches are caused by various factors, which can sometimes be fixable, and sometimes not.

If you want to know the causes behind these white patches appearing on your screen and whether they can be fixed for good, this article is for you. We will also look into the fixes for this problem in detail.

What causes White Spots on Samsung TV?

Numerous reasons can cause white Spots on your Samsung TV. However, we have mentioned below the leading causes behind this problem.

1. Dislodged LED Reflectors:

A dislodged LED diffuser lens is typically to blame for the white spot on a Samsung TV screen.

The bright LED light bulbs are covered by LED diffuser lenses, which distribute the light evenly across the TV screen. White light from the LED bulbs shines directly through the screen when they fall off. Assuming more reflectors lose up, you will find more than one white spot on the screen.

Diffuser lenses can become dislodged when the adhesive dries or breaks down. Any impact or even moisture in the air can also cause them to fall off.

If you find white spots on your TV with a diameter of around 2 inches, this might be the cause. Also, to confirm the cause, you can gently shake the TV. Some lenses have fallen off if you hear stuff moving inside.

2. Dead Pixels:

Millions of pixels and dots help to light up and create the image on the TV screen on every LCD and LED model. Frequently the issue emerges when any pixels are harmed and caught stuck in a specific screen region; when the electrical voltages that pass through the transistors that power the sub-pixels are not detected or received, dead pixels occur.

Commonly this is due to a bright dot defect or hot pixel, which is usually caused by the problem with the transistors, due to the electricity voltage. However, if the dots appear very tiny, it might be due to a problem with the main board.
