How To Get Rid of Blue Screen on TV? | Step-By-Step Guide

If you have landed on this article, I believe you are facing a blue screen on your TV, and you are too panicked. Isn’t it right?

Generally, a blue screen on a TV is caused due to an issue with the video cable (HDMI cable). To fix this issue, ensure that the HDMI cable is connected correctly to the TV. Also, inspect the HDMI cable for any signs of damage, such as tears, cuts, exposed wires, or knots.

If you find any such damage, replace the cable, as it could be causing the blue screen issue on your TV.

In the world of TV, a blue screen is generally termed as the “Blue screen of death” and is seen as irreparable damage. But, it’s not always true as there could be other causes of a blue tint that can be easily fixed.

So, let’s get into this and understand the causes and how you can fix the blue tint issue in your TV.

Why Is The Screen Blue on My TV?

Why Is The Screen Blue on My TV

Your TV has a blue screen when the source or input device is not set up properly, or there’s an issue with video input. However, the blue screen can also appear if there’s a hardware problem, for example, an issue with the T-con board.

Sometimes, it could be just the wrong color distortion. You can use our guide on how to fix color distortion on a TV.

Most of the time, a blue screen on TV has the same reasons as a black screen. Here’s our guide on how to fix a black screen on TV.

But, if you think that your TV might have a blown fuse, check our guide to identify a blown fuse and how to fix it.

Now, let’s get into the common causes of a blue screen on a TV.

Source or Input Device Isn’t Set up Correctly

One of the primary reasons why your TV might be displaying a blue screen could be due to improper setup of the source or input device. 

For example, if you’re using a coaxial cable to connect your cable box to your TV, your TV must be set to a program channel to receive a signal and not a TV/Video input. 

If not correctly set up, the TV may not receive the appropriate signal, resulting in a blue screen. Therefore, it’s important to ensure the correct setup of your input devices to prevent such issues.

Issue With Video Input

If your TV screen is turning blue and displaying a “no signal”, the problem is with your video input.

You can quickly fix this issue by setting up the correct video input to your TV.

Defective Backlight on an LCD TV With an LED Backlight

Most LCD TVs are equipped with an LED backlight, which enhances the brightness and color of the images on your screen. Without this backlight, the display would appear dark.

The LED backlight emits a cool-toned light, and when the TV is switched on, it can add a slight blue tint to your screen. This should be barely noticeable and not cause significant inconvenience.

Sometimes, the LED backlight might be defective, causing blue colors to start appearing all over your screen.

Problem With T-Con Board

A malfunctioning T-Con board can also result in a blue screen on your TV. The problem could range from something as straightforward as a loose connection between the T-Con board and the panel, to a defective T-Con board itself. 

Other potential causes could include a damaged capacitor or an improper power output from the panel to the T-Con board. 

If the T-Con board is not functioning correctly, it typically results in a black or blank screen.

How Do I Fix The Blue Screen on My TV?

How Do I Fix The Blue Screen on My TV

In 90% of the cases that we have analyzed, the blue screen on a TV was due to a connection problem.

Here are our six troubleshooting ways to fix a blue screen problem on a TV. Use these and thank me later!

Unplug the TV and PUT It Back In

Like any other device, your TV has processors that keep your TV running. Sometimes, these processors can crash.

Unplugging your TV from the power source for around 10 minutes can reset the microprocessor.

So, unplug your TV and put it back after 10 minutes and see if that fixes the problem.

Adjust the TV Display Modes

Sometimes, you may see a blue screen on your TV due to some technical glitch and adjusting the display mode restores the image quality.

Here’s how you can adjust the display mode on your TV:

  • Press’ Menu’ button.
  • Look for ImagePicture, or Display Mode in Settings.

You will find preset modes such as Bright or Cinematic. Switch these modes to check whether this resolves the problem. (Other modes that you can find are Standard, Natural, or Movie.)

Set the Color Temperature on Your TV to Warm

Here’s how you can set the color temperature on your television:

  • Press the ‘Menu‘ button on your TV’s remote.
  • Search for a category labeled ‘Color Temperature‘. This section usually contains presets with labels like ‘Warm‘ and ‘Cool‘.
  • Change the color temperature setting to ‘Warm‘ and check if the blue screen goes away.

Note: Some TVs may display color temperature in Kelvin degrees, such as 6500K or 5700K. If your television shows in Kelvin, adjust the setting to below 5000K for a warmer screen tone.

Check Audio/Video Input and HDMI Cables

Check Audio/Video Input and HDMI Cables

When the Audio/Video input is not connected properly or if there’s a weak HDMI connection, you can get a blue screen.


  • Make sure the Video input is connected correctly to your TV.
  • Check your HDMI cable is connected firmly to the TV and that there are no signs of wear or tear, including cuts, knots or exposed wiring.
  • Replace the cables if they are damaged.

Check Source Device Settings

Ensure that all output settings on your source device are activated. Once this is done, switch to a different source device as a test to see if the blue screen is still there.

Disconnect Devices That Can Cause Interference

When there are other devices, such as gaming console, AVR, etc., that are connected to your TV, they can cause signal interference.

Press the Input button on the remote and select another HDMI port. If you can still see the blue tint on the screen, unplug other connected devices and check if the problem is solved.

Check Your TV For Hardware for Faulty

Check Your TV For Hardware for Faulty

Your TV’s hardware might be at fault if none of the above troubleshooting tips worked for you. This step requires some technical board knowledge, and I recommend getting your TV repaired by a professional. You will have to test the power board voltage, and you may have to replace the TV T-con board.

If your TV is under warranty, contact customer support ASAP to get your TV repaired free of cost.

How To Fix A Blue Screen on an LED TV?

If your LED TV is consistently displaying a blue screen, there could be two potential reasons:

  1. The TV is functioning as intended but naturally implicit a blue tint.
  2. The TV’s LED backlight is faulty.

LED backlights are common in most LCD TVs due to their brightness, slimness, and efficiency. However, they often emit a cool color temperature, which may result in a subtle blue hue. This is particularly noticeable when viewing white images and less for other colors. 

Adjusting your TV’s color temperature can help mitigate this issue, although it might not completely remove the blue tint.

On the other hand, if the blue tint is visible on all colors displayed on the TV, especially visible in dark gray or even black areas of an image, the LED backlight might be defective. 

A faulty backlight will emit a blue light regardless of any color temperature adjustments you make on the TV settings.

If your TV naturally has a blue tint, you can manage this by switching the color temperature to the warmest setting available. 

However, if the backlight is defective, the only solution is to get professional help. You can either reach out to the TV manufacturer for warranty repair or take your TV to a local repair shop.

Should You Worry About A Blue Screen in an OLED TV?

You should not worry about a blue screen problem with an OLED TV since the technology in OLED displays is quite different from a typical LED TV.

This means that the blue tint problems that can arise from a malfunctioning backlight in an LED TV don’t usually occur with OLED TVs. However, you may notice a blue tint when the HDMI cable is not connected properly or damaged.

Also, a faulty OLED panel can result in a noticeable, permanent blue tint. But, you can quickly notice such a defect at the time of the TV’s unboxing.

Key Takeaways

  1. The blue screen could be due to a damaged HDMI cable. Check if it’s properly connected and look for any visible signs of damage. If damaged, replace it.
  2. The “Blue screen of death” isn’t always a death sentence for your TV. There can be other causes of a blue tint that are easily fixable.
  3. If the source or input device isn’t set up correctly, your TV might display a blue screen. Ensure the correct setup to prevent such issues.
  4. If your TV displays a “no signal” message with a blue screen, there might be an issue with your video input. Make sure the correct video input is set up.
  5. An LED backlight adds brightness and color to your TV screen. However, a defective one can cause blue hues to appear across your screen.
  6. A malfunctioning T-Con board can also result in a blue screen. An improper power output or a damaged capacitor might be the culprits.

Remember, you don’t always need to rush to a repair shop. Try these troubleshooting tips first, and you might save yourself some time and money!
