1. Unplug your LG TV from the power outlet to perform a reset.

The first recourse you need to consider when troubleshooting an LG TV blue tint issue should be unplugging it from its power source to reset it. Unlike more technical solutions, simply resetting your TV this way is quick and easy to do.

Unplugging your LG TV will immediately shut it down, and its system will refresh its memory once electricity is reintroduced. We also recommend performing a power cycle to eliminate residual electrical charges from the capacitors while it’s turned off.

Power cycling goes far beyond your usual unplugging from the wall. Though it takes a minute or two, the solution is much more effective. 

Follow these steps to reset your LG TV quickly:

  • Disconnect your LG TV from its power source.
  • Plug it back in after 30 seconds of keeping it unplugged.
    Note: Please ensure its power cable is securely plugged into the electrical outlet.

Follow these steps to perform a power cycle on your LG TV:

  • Disconnect your LG TV from its power source.
  • Press/hold the power button on the LG TV.
  • Wait for 30 seconds and let go of the power button.
  • Wait for another 30 seconds and then plug the LG TV back into the electrical outlet. Note: Please ensure its power cable is securely plugged into the electrical outlet.


Resist the temptation to rush things up and not observe the number of seconds you should wait before doing the next step. The specified period of time is essential as it ensures your unit is reset right and free of any electrical charge. 

2. Check all of your LG TV’s HDMI connections.

This next troubleshooting trick for solving the LG TV blue tint issue involves physically inspecting its HDMI connections. 

  • Check if the HDMI cable is connected securely to your LG TV and the external input device.
  • You can unplug and re-plug the HDMI cable on the TV and the input device to ensure they’re plugged in tightly on both ends. 
  • Once the connection is secure, you should look for signs of damage on the HDMI cables.
    Note: The type of damage on an HDMI cable you must look for is the usual wear and tear on the wire. Also, ensure no dirt on the HDMI ports and connectors that might mess up the connection.

  • If you find out your HDMI cable is faulty, you can replace it with a new one. In the case of a faulty HDMI port, you can switch to another one if your LG TV has multiple ports available.

    Note: If your LG TV only has one HDMI port or if all of them are busted, go to the LG product support page and contact them for assistance or book a repair service. A faulty one may take a lot more expertise to repair. 

3. Reconfigure the picture settings of your LG TV.

Since the LG TV blue tint issue affects the display, you should be able to remedy it by adjusting and changing the picture settings. Depending on how intense the blue tint on your LG TV is, you might be able to remove it entirely or just reduce its effect.

Please note that every LG TV model has different options and features under the picture settings. If your TV doesn’t have some of the options in our example, only adjust and change those available to see if that fixes the issue.

Follow these steps to adjust the picture settings of your LG TV:

Press the gear button  on the remote control to open the settings
             panel on your LG TV screen.
Step 1: Press the gear button on the remote control to open the settings
            panel on your LG TV screen.

Step 6: Select/click Brightness and adjust the display’s brightness level.

Other LG TV models will have a Smart Picture Mode to switch the picture mode to a pre-programmed selection of options such as Vivid, Standard, APS, Cinema, Sports/Soccer, Game, HRD Effect, Photo, Technicolor Expert, and Expert.

So, it’s important you take note of your TV model so you can factor repairs right, especially true with new models coming in every year. 

4. Run a Picture Test or Screen Self-diagnosis on your LG TV.

If you’re unsure what adjustments to make to fix the LG TV blue tint issue, you can perform a picture test instead. This option provides you with a test image to inspect its quality, and you’ll get some suggestions based on the result.

Depending on the webOS version or model of your LG TV, the picture test might instead be called screen self-diagnosis. In this case, you will find this option in the support settings, not the picture settings.
