Everyone loves to enjoy their favorite shows on TV. But, sometimes your TV has blue or green tint. This ruins the watch experience.
Everything on your TV screen looks blue or green. This happens due to some wrong picture or display settings. Another cause is the malfunctioning backlight.
In addition, some intricate hardware defects can also lead to this issue. This article will consider all these causes and their solutions. Apply all the tricks mentioned in this guide.
1. Inherent Blue Tint
There are a lot of TV brands in the market. Today, smart LCD TVs are very popular. However, some people still own previous models.
The blue or green tint can be native in the TV. It means the TV screen is inclined to give blue shade. When you watch the screen sitting from a direct angle, the display is normal.
As you move towards sides, the blue or green tint gets stronger. So, you should check whether it is the integrated feature of your TV or some real issue.
2. Adjust Picture Settings
Blue or green tint on a TV also indicates faulty settings. You can adjust the picture settings by the following method;
- Press the ‘Menu’ or ‘Home’ button on your TV remote.
- The TV screen will show you a list of settings. Choose the settings named as ‘Picture/Image/Display’ mode.
- Navigate to the ‘Cinematic’ or ‘Bright’ mode. Switch between these two modes and see if it makes any difference.
Some TVs have preset color modes such as vivid, night, dark, standard, game, etc. Shift between different modes to see if it makes any difference.
Also, adjust brightness, picture tint, and white balance in the settings. Increase or decrease the brightness to fix the issue.
Some TVs offer RGB mode that provides red, green, and blue tints. You should check this factor from picture and color settings. Apply the normal mode and disable RGB.
3. Set Color Temperature
This setting can affect the picture quality on your TV screen. Cool temperatures tend to give a blue tint. While higher color temperature is likely to brighten the picture.
So, adjust the color temperature settings by the following process;
- Open TV settings by pressing the menu button on the remote control.
- Navigate to the ‘Color Temperature’ settings. It has preset options like ‘Warm’ or ‘Cool’.
- To remove the blue tint, change the color temperature settings to ‘Warm’.
- The color temperature settings depend on the TV model and brand.
- Some TVs show the color temperature in Kelvin. You should choose below 5000K to remove the blue tint.
- You should also check the color temperature of the device that is sending video signals to your TV.
- For example, a Blu-ray, gaming console, laptop, etc. may be connected to your TV.
- Kindly read the user manual of your device to find the exact method.
4. Check the Connection Cables and Ports

Inspect the connection cable along its entire length. If it is damaged, replace the cable with the new one. As a trial, use a different cable if the issue is solved.
Furthermore, examine the connection ports, they should not be broken and the cables should fit firmly into them.
Also, check the antenna, cable box, Ethernet cable connected to your TV. You should ensure that all these devices are working properly and sending signals.

This trick proves very effective in solving a number of issues. Blue or green tint can be caused by a temporary software glitch.
Power cycling your device can remove the bugs. The process is as follows;
- Disconnect all the external devices from your TV.
- Unplug your TV from the wall power outlet while it is turned ON.
- Leave it for 1-5 minutes. Now, plug the power cord back into the wall outlet.
- Turn ON your TV by pressing the power button and connect the devices one by one.
- Because sometimes, an external device is responsible for a blue or green tint on your TV.
- You should carefully observe which device causes the issue. Then, troubleshoot the problematic device.

Normally, users do not bother to clean their TV. Therefore, it catches a lot of dust that blocks the vents. This condition creates many problems and your TV starts malfunctioning.
Hence, you should clean your TV regularly. Turn OFF your TV, disconnect all the cables and clean the connection ports using a new toothbrush and soft cloth.
Also, clean the vents at the back of the TV. Do not use a sharp tool to avoid any damage. Check the picture quality after a thorough cleaning.
7. Defective Backlight
Modern flat-screen LCD TVs use LED backlight. If this light becomes defective, your TV screen will show a blue or green tint.
You can recognize it by noticing all colors on your TV. If only the picture shows a blue tint, the backlight is fine.
However, a blue tint may appear on everything, and in each color such as dark gray or black parts of the image also look blue.
This situation cannot be fixed even by changing the color temperature to warm. If this is the case with your TV set, it’s time to contact the manufacturer.
Unfortunately, the LED backlight of your TV has stopped working. So, ask the company to repair it.
