Blue Tint on TV (Causes, How to Get Rid of the Blue Tint)

Despite today’s modern advancements, TV screens aren’t immune to color issues. In all my years of repairing TVs, I’ve experienced it all: black screens, discolorations, odd tinting—the list goes on! Among these issues is the dreaded blue tint on TV, which is surprisingly common on modern flat-screen TVs. 

Blue tinting on TV is usually caused by three things: improper color calibration, loose or damaged HDMI cables, or defective LED backlights. Solutions range from adjusting the TV’s settings to replacing the backlight LED strip. 

I’ll go through each of these issues and show you how to get rid of the blue tint on your TV. Let’s dive right in!

Improper Color Calibration 

Blue tinting on TV is often caused by incorrect color settings on your TV or device. 

You may have accidentally switched the colors around or pressed the wrong option while adjusting your TV settings. 

If you’re using a second-hand TV, the previous owner might have adjusted the color settings too high on “Cool,” resulting in an obvious blue tint on the screen.  

How to Fix 

To fix this issue, you’ll simply need to go to your TV’s display settings

The exact step-by-step method differs from brand to brand, but you’ll generally need to press Menu on your TV’s remote, then go to display settings. 

From there, navigate to Picture Mode, Display Mode, or Image Mode and look for a section labeled Color Temperature

This option will present you with two options: Warm and Cool. Change the color temperature to Warm or manually adjust it to below 5000K. 

If you don’t want to mess around with the color settings, select an option that says Reset or Return to Default Settings. This will reset the color settings as intended by the manufacturers. 

Loose or Damaged HDMI Cable 

HDMI cables transmit video and audio signals from one device to another. If damaged or improperly inserted, they won’t render the screen colors properly. The screen might appear glitchy, blurry, or bluish as if covered in a thin veil. 

How to Fix 

To fix this issue, all you need to do is turn off the TV, unplug the HDMI cable from the device, wait about 10 seconds, and plug it back in. Make sure both ends are firmly and properly attached to the devices before turning the TV back on. 

If the problem remains, there might be an issue with the HDMI cable itself. It might have some internal wiring damage or physical wear and tear. 

You can check the status of the cable by inserting it into a different device. If the color appears odd on the other device, it’s time to get a new HDMI cable. 

Also, you’ll want to check the TV’s HDMI port. The port might’ve been damaged as a result of improper insertion. If the port’s pins appear wonky or flat, contact a technician to replace them for you. Unless you’re comfortable with soldering tiny connections, don’t attempt to fix the damaged port yourself.

Defective LED Backlights 

Most modern flat-panel LCD TVs are equipped with LED backlights to illuminate the TV screen and add depth and vibrancy to bright colors. 

The backlights are mostly white in color, but they do cast a slight blue tint depending on the TV’s color temperature. This blue tint is subtle, and you’ll only ever notice it when viewing a white image. 

If the blue tint is prominent and bleeds into all colors shown on the TV, there might be an issue with the backlights themselves. They might have short-circuited, burned, or failed. 

How to Fix 

Unfortunately, there’s no on-and-off fix to this problem. Defective LED backlights can’t be repaired, especially if they’ve short-circuited. They instead must be replaced with brand new LED backlights. 

Though you can replace the LED backlights yourself, I strongly recommend against doing so unless you’re well-versed in TV components and repair. It’s best to take the TV to a professional to avoid further damaging the screen. 

Try a soft reset

A soft reset, is where you turn off the TV and unplug it from the wall outlet. You then usually have to wait for 60 seconds then you can put the plug back in and turn the TV on again. Performing a soft reset clears a device’s internal memory of running programs, which often clears up any technical glitches.

Try a hard reset

A hard reset involves completely resetting the TV to its factory defaults. Most TV models have specific instructions.

Conclusion 

As you can see, there are multiple causes of blue tinting on TV. 

Usually, it’s a result of improper color calibration or either loose or damaged HDMI cables. 

Both issues have relatively easy fixes; for the former, simply adjust the color settings of your TV or return it back to Default. 

For the latter, just make sure the cables are properly inserted into the port. If the HDMI cable shows signs of wear and tear, it’s best to replace it with a brand new one as old cabling can also cause blue tinting on TV. 

If both solutions don’t work, the blue tinting might be caused by defective LED backlights. This is the worst-case scenario; you’ll have to take the TV to a technician to replace the backlights for you.
