| Published:

When you notice that your LG TV has a green tint, it can be very concerning.

In this post, we look at the potential causes of the LG TV green tint and how to resolve it.

Why does my LG TV have a green tint?

The reason for the green tint on your LG TV is usually due to one of the following: software problems, malfunctioning ports, incorrect settings, or improperly configured external devices.

How to remove the LG TV screen with a green tint?

Here are some important steps that you can take:

  • Soft Reset your LG TV
  • Update your LG Firmware
  • Check your input devices for issues
  • Switch your HDMI cables
  • Reset the LG TV to the initial settings
  • Check for backlight failures
  • Contact LG Support

Step 1: Soft Reset your LG TV (All LG Models)

Just in case you haven’t already tried this, do a soft reset and see if this removes the green tint from your LG TV screen.

Unplug your LG TV and wait 60 seconds before plugging it back in, this will power cycle the TV.

What does unplugging your LG TV do?

When you unplug your LG TV for around 60 seconds, it does a soft reset of the system.

The soft reset allows any updates that have been downloaded in the background to be successfully installed and started.

The soft reset also clears the system cache.

Performing the soft reset can help resolve the green tint issue if it is a software problem or a TV configuration issue that is causing the green tint.

Step 2: Update your LG TV software

Keeping the LG TV software up to date can assist you in preventing some issues, such as a green tint screen that can appear over the lifespan of your TV.

Most LG TVs have automatic updates enabled by default, and the updates should install automatically assuming that your TV is connected to the internet.

It is possible, even with this setting enabled that updates can be missed or an installation can be interrupted and thus cause issues with your TV.

Older LG firmware or a partial software installation could be causing the green tint screen problem and we strongly recommend that you update your LG TV firmware to ensure that you have the latest software, access to new apps, and an improved viewing experience.

Ultimately, regular updates improve your viewing experience and give you better security & privacy protection.

How to update your LG firmware

Assuming your TV is already turned on, hit the settings button on the remote.

Now you will see the settings menu appear on the left-hand side of the TV (please note that this may vary depending on the model of your LG TV).

At the bottom of the row of icons, you should see all settings button. Please select this option to proceed to the next menu.

Now navigate down to “SUPPORT” on the new menu that appears and then select “SOFTWARE UPDATE”

Now you can activate the automatic update feature and also check for new updates.

Step 3: Change your selected input device/source

Before we get into some of the more lengthy potential fixes for your LG TV’s green tint issues, we should try checking other input devices/sources.

You can change the input device or source by pressing the corresponding button on the LG remote, as shown in the image below.

LG remote source / input button

Once you have pressed this button you are shown a list of available inputs. Inputs are the devices that are connected to your LG TV. This could be a DVD player, Cable Box, Firestick .etc

You should navigate through all of your inputs to see if the green tint issue is still present when you switch through the different inputs.

If the green tint is only present on 1 or more of your inputs but the image displays normally on others then this would suggest that your TV is fine, it may limit the issue to an external device (like those listed above) or alternatively an input device I/O issue.

What is an input device I/O issue?

I/O stands for input/output – it generally refers to the different ports on your TV like, HDMI, DVI, DisplayPort, USB.etc.

It is not uncommon for a port to become damaged or unusable after prolonged use or an extended period of plugging and unplugging cables into the same port.

I/O Input issue example:

The green tint is only present on HDMI 2

This would suggest that you have a damaged HDMI 2 port or a bad HDMI cable.

Step 4: Switch your HDMI Cables

HDMI cables can differ in both quality and longevity.

The green tint on your LG TV may be the result of a bad HDMI cable.

If you commonly run content from a device that is connected to your TV, we recommend switching the HDMI to see if that can resolve the problem.

Step 5: Reset your LG TV to the initial settings

Your green tint issue on the LG TV could be caused by incorrect picture configuration.

If none of the other steps have helped in resolving the issue, give this method a try.

Option 1: Newer LG TV Models

  • Settings
  • All Settings
  • General
  • System
  • Reset to Initial Settings

Option 2: Older LG TV Models

  • Settings
  • All Settings
  • General
  • Reset to Initial Settings

Step 6: Back Lighting Failure (Generally occurs in older LG TVs)

A green screen can be a common issue on older LG LED TVs when the blue/green light eventually bleaches the yellow phosphor, eventually, turning the LED screen green.

How to prevent LG backlight failure

If you are not yet at the stage of failure, it is worthwhile reducing the brightness of your TV.

When you initially purchase an LG TV from your local electronics store, the brightness level can often already be set to 100.

This excessive brightness can lead to issues over time.

Option 1: Call your local electronic repair store

If you believe that a backlight failure may be the cause of the green tint on your LG TV, it may be time to call your local electronic store so that they can diagnose the issue.

We recommend that you perform your due diligence when selecting a local store for repairs, check their Google Reviews, and possibly get a secondary quote.

It is also worth considering just buying a new TV if you believe that your TV needs repairing.

Factor in the age of your LG TV and the quoted cost of repairs, and it may be more economical in the long run to just purchase a new TV, with older TVs, other issues may arise over time.

Option 2: Repair the LG backlight failure yourself!

To the braver LG owners, you always have the option of repairing the TV unit yourself.

Be aware that you should do this assuming the risk of causing more damage to your TV and potentially invalidating your warranty (If your TV is newer and still covered)

Contact LG Support

If none of our tips have helped in resolving the LG TV screen green tint issue, then it might be time to consider contacting LG support as you may have a defective TV unit.

LG may be able to advise you of other things to try or help diagnose the root cause of the issues.

I would strongly recommend contacting LG before you consider any other fixes that may invalidate your warranty or cause further damage to your LG TV.
