Tv Screen Green

Today, televisions come in different types, from CRTs to LCDs to plasma screens. So the display color issues are also diverse and problematic. The one you might be facing is the green screen.

Quick Answer

It is possible to fix the green screen on your TV by replacing damaged or loose cables, repairing bent cable connectors, power cycling your TV, adjusting color properties, or factory resetting the TV.

Although the green screen may hinder your viewing experience, this does not mean that your television display won’t get back to normal. We’ll explore why this happens and guide you with step-by-step instructions to fix each of the causes.

Why Is My TV Screen Green?

If your TV screen has turned green, it could be due to the following reasons:

  • Loose or damaged cable connections
  • Bent TV connectors
  • Incorrect HDMI input on streaming devices or TV
  • A temporary glitch in TV software due to power fluctuation
  • Misconfigured color settings.
  • HDR and RGB settings are enabled.
  • Hardware defect in the TV screen.

Fixing Green Screen on TV

Fixing the green screen on a TV is not as complicated as it sounds. But our step-by-step instructions will save you a lot of time and take you through the troubleshooting process without any hassle.

Now that you know the possible causes, it is time to reveal the four methods of resolving the green screen problem on your TV.

Method #1: Checking Cables and Connectors

Loose cable connections, damaged cables/connector pins, and wrong HDMI inputs are the common reasons for various TV issues. Luckily, you can rule out these possibilities by following these steps.

Step #1: Verifying Loose Connections or Damaged Cables

Visually inspect the TV and see if any cables such as HDMI or power cables are loose or damaged. Next, firmly tighten the loose cables and replace the damaged ones.

If the issue persists, check the TV connector pins. If the connector pins are bent, use a long thin metal object to straighten them out.


Trying to straighten out the connector pins yourself might break the pins and result in costly repairs.

Step #2: Checking HDMI Port

If your TV shows a green screen while connected to another device and streaming content through an HDMI cable, you may have inserted the cable in the wrong HDMI port on either the streaming device or the TV.

Here’s how you can fix the HDMI port issue on your TV.

Connect one end of the HDMI cable to the HDMI port (HDMI 1 or HDMI 2) on your streaming device. Now connect the other end of the cable to the same HDMI port number on the TV as the streaming device.

Finally, verify that the green screen problem is resolved.

Method #2: Power Cycle/Reset Your TV

Sometimes, temporary software bugs due to power fluctuations can cause the TV screen to exhibit a green color. To quickly fix the issue, you can power cycle or reset the TV.

  1. Turn off your TV and unplug the power cable from the primary power source.
  2. Now Wait for 10-15 minutes.
  3. Next, plug the power cable into the power source and switch on the TV.
  4. Check the TV screen to see if the issue has been fixed.

Method #3: Adjust Color Settings

You might have switched on your TV’s HDR/RGB mode or changed your TV color settings, causing the issue.

Step #1: Disable HDR and RGB

HDR and RGB for TVs display a more natural image by adding more contrast and colors. However, this can lead to a green screen issue on your TV. You can quickly disable the HDR+ and RGB on your TV by pressing the Home/Menu button on your TV remote.

Now navigate to Options/Settings > Picture > Expert Settings. Select the HDR+ mode option and switch it Off. Next, go back one step, select the RGB Mode Only option, and switch it off as well.

Step #2: Adjust Screen Brightness

If the problem persists after disabling the HDR+ mode, try to adjust the screen’s brightness.

Press the Home/Menu button on your supplied TV remote. Just like in the first step, navigate to Expert Settings or Picture.

Select Brightness and move the slider to remove the green hue on the screen.

Method #4: Reset Your TV

If the green screen persists after the power cycle procedure, the last step you should try is resetting the TV.

  1. Press the Home Button on your TV’s remote control.
  2. Select Settings > Support > Self Diagosis > Reset.
  3. Input the security PIN and select the Reset option again.
  4. Wait for a few minutes to let the TV complete the Factory reset process and restart automatically.
  5. Now confirm that you don’t see a green screen anymore.

Performing a reset process will erase personal customizations settings and restore the TV back to its default state.
