Why is My TV Green-Screened?
In general, all TV display panels use green, red, and blue pixels. The TV module controls the brightness of these pixels to display images correctly on the screen. If there’s an issue with the TV module, which manages brightness, software, and hardware, your display might turn off or display an entirely green screen and behave oddly. If your TV module is functioning correctly, you should inspect the HDMI cable. This cable is responsible for transmitting both audio and video between devices. If it’s damaged or broken, you will observe a green screen on your TV.
1. Loose Cable Connection
There are mainly two types of cable used in TV.
a. Power Cable
It should be your priority to check the power cable to troubleshoot and fix the issue. If you have a poor-quality cable that is damaged or loose, then your TV does not have a proper connection, and due to this, the TV does not work properly.

b. HDMI Cable
The main cause of the green screen issue is typically a loose HDMI cable connection or a damaged HDMI cable. HDMI, which stands for High-Definition Multimedia Interface Cable, is used to transmit high-definition video and audio from one device to another. If your HDMI cable isn’t securely connected, it can lead to display problems. In many instances, the cable tends to be loose or damaged. To determine if the cable is damaged, inspect the bottom part of the cable. If you notice burn marks or it turns black, it’s time to replace the old cable with a new one. Afterward, check if your problem is resolved before proceeding to the next step.
2. Improper Picture Settings
After you have examined the cable for loose connections and the issue persists, you should inspect the TV unit’s display settings. These settings are crucial for maintaining the quality of your screen display. If the display settings are incorrectly configured in terms of saturation, contrast, or brightness, it can result in undesired colors on the screen, leading to an improper display. To address the green screen problem, pay special attention to the sharpness of the green color. An incorrect setting can cause abnormalities in the colored display, resulting in the green screen issue. If you wish to adjust these settings, access the menu bar and navigate to the display settings. Make sure that the color temperature and other settings are appropriately configured. If any setting is at an extreme value, you will need to make adjustments to bring them into balance.
3. Hardware Problems
After examining the cable and display settings, if you’ve completed all the basic troubleshooting steps and your TV screen still displays a green hue, there’s a significant possibility of hardware problems or even issues with the motherboard. This could be attributed to a damaged ribbon cable inside the TV or potentially some display components within the TV unit being damaged. If you identify any hardware problems, it’s advisable to get in touch with the TV manufacturer. Most brands provide a one-year warranty. Check if your TV is still under warranty; if not, you will need to cover the repair costs yourself.
4. Software Glitches
Believe it or not, software updates can sometimes fix issues with your TV screen. Smart TV manufacturers regularly release software updates to improve performance and fix bugs. An update could be the solution you need. Typically, these updates happen automatically. However, if you want to address a software problem on your TV manually, you’ll need to perform a manual update. Once you’ve updated to the latest software version, you should restart your device and check if the screen issue has been resolved.
How Do I Remove a Green Screen from My TV?
1. Restart TV
One of the easiest ways to fix some software bugs is to restart your TV once. Something stuck in your smart TV’s flash memory can also cause a green screen on your TV. To cut off your power supply, flash memory will be reset from your main board without losing any personal settings. Let me explain how to restart your TV below:
- Switch off the button on the main board and unplug your TV.

Note: Make sure you switch off your TV for at least 15 to 30 minutes.
2. Check the Power Source and Cable Connections.
The power cable and HDMI cable are essential components for your device. If either of them becomes damaged or broken, you may encounter issues such as a green screen or a non-responsive display. To prevent these problems, it’s crucial always to ensure that both the power cable and HDMI cable are in good condition. These cables are integral to the proper functioning of your connected devices.
To check their condition, you should physically inspect both cables. Unplug them and carefully examine each one for any signs of damage or breakage. If you observe any cuts on the cable or notice that its connectors are discolored, it is advisable to replace the cable. Obtain a new cable and follow the necessary steps to connect and secure it in the same manner as before. This should resolve the issues you were experiencing.
3. Check the Display Settings.
If your display configuration is incorrect, you may encounter a green screen issue. There are certain default display settings that you should always check before making any adjustments. These include HDR and RGB mode. You can disable these settings to ensure proper image quality. Additionally, you may need to make changes to other settings like contrast, sharpness, and brightness to achieve the perfect image. To do this, navigate to the settings option, select the picture settings, and make the necessary adjustments to color or brightness. It’s important to note that every TV manufacturer provides different options for adjusting settings, so it’s advisable to consult the user manual for specific guidance.
4. Disable HDR and RGB Mode
HDR stands for high dynamic range, and RGB stands for red, green, and blue. Both settings are designed to improve the picture quality of the TV. However, when you activate HDR mode, it increases the contrast between dark and light colors on the TV, resulting in brighter whites and deeper blacks. On the other hand, RGB mode allows you to emphasize a specific color. If you enable both settings simultaneously, you will encounter a green screen issue. To resolve this problem, you need to deactivate these settings.
To Disable HDR Mode, Follow These Steps:
- Open the menu and select Settings.

Every smart TV manufacturer periodically releases software and framework updates to address various issues, including bugs. These bugs might manifest as the green screen problem on your TV. To resolve such issues, companies provide updates for your TV. In most cases, these updates are automatically installed. However, to ensure the updates are applied, you need to have a Wi-Fi connection for downloading. A stable and fast internet connection can facilitate a quick and seamless download process.
