Causes of LED TV to Change Color and How to Fix it

TV is very important entertainment, especially in the current pandemic era. In addition, TV can also be a good educational tool to teach children about various things. Today, the world has switched to LED TVs instead of LCD or tube TVs.

This is due to the advantages of LED TV which are more environmentally friendly, thinner, lighter, more durable, more environmentally friendly, have many additional features, and are easier to maintain when compared to other types of TV.

However, although LED TVs have many advantages, LED TVs can also experience interference if there are errors in installation or settings. One of the most common disorders is related to discoloration.

These color changes can certainly interfere with the comfort of watching television, even in the worst case it may damage your eyes.

Generally, there are two types of interference with TV color, namely those related to color temperature and color distortion. In this article, we will explain what causes color changes in LED TVs.

1. TV Functions Correctly But Has a Default Blue Color

Most flat-screen LED TVs have an LED backlight. LED backlights are generally bright, sleek, and efficient, but have cool color temperature lighting that produces a slight blue tint. The color will be clearly visible on a white image, and not visible on other colors.

What is color temperature? Color temperature is a TV control that is in the TV settings but is rarely changed. Though this setting is the most important thing in the TV display.

Generally normal TV has a standard temperature of D6500 (or 6500 K). If the setting is changed, it will produce colors that are more inclined to one color, such as red, blue, or green.

2. The Distorted TV Screen Image

Another cause of discoloration on the TV is that the picture may be distorted. Light distortion is a term that describes the failure of a lens to focus all colors onto the same point.

A distorted TV shows colors that sometimes flash red, green, or white repeatedly. There are several things that can cause the screen image on the TV to be distorted:

Loose Cable or Wire

Loose cables or wires can affect image quality and colors. This is generally not realized or noticed by most people.

Picture/Video Settings Error

Picture settings from TV to TV are generally different. So it is necessary to study the location of the categories of this arrangement. To fix this can be done by searching on google and studying the resolution of the TV you are using.

Insufficient Power

Every electronics has different power requirements. If the TV is not getting enough power, it can distort the screen.

In addition, the image on the screen may become buzzy and foggy. To fix this, you can check whether the power cable is properly installed.

Video input is broken

Generally, distorted colors can also be caused by a damaged or dirty video input, such as a USB, HDMI, RGB, or coaxial cable. The buildup of dust on the video input can have a negative effect on the input of the television.

Problem with T-Con Board

The distorted color issue could also stem from the T-Con board. The T-Con board is a piece of electrical electronics that takes the individual frames generated by the GPU, corrects color and brightness, and sends parts of the image to each individual driver at a specific time on the panel.

Damage to the T-Con board can result in faded and whiter colors on LED TVs.

3. Other Hardware Problems


Mainboard is the main board that contains components and controller chips. These components are useful for regulating the movement of data in the system motherboard.

Errors in this section generally cannot be resolved on their own, and need to be handled by experts.

Remote Part

The next problem could come from the remote settings. Maybe while watching television, there is an accident in pressing which changes the normal color of the TV being used.

Here are some explanations regarding the causes of LED TVs changing colors. To fix this you can double check your TV settings or re-tighten loose cables.

But if the problem still persists, it’s a good idea to call an experienced technician to fix it. But if you are confident enough in your own abilities, you can try to fix it according to instructions that can be searched on google or in the manual of the TV.
