TV uses an RGB (Red, Green and Blue) color model to generate images on the screen. So, if your TV is mostly greenish, it is because the intensity level of green color is higher than the others.

It generally happens due to loose cable connections or when the color settings like Hue and Tint on your TV are misconfigured. Also, it is possible that the display components like T-Con board and LVDS cable are damaged.

Check Connections and Source Devices

A loose or faulty cable connection is the primary reason your TV can show a green screen. So, you first need to check if the source cable connections like HDMI cables are tight and secure. Unplug all the associated video cables and re-plug them. Also see if there are any frays in the cable. If any, consider using a replacement cable.

Likewise, as most of the users reported, they faced the green screen issue when trying to play 4K content on their TV. It is because the TV or the cable that you are using does not support the high resolution video. If you are sure your TV is capable of playing 4K video, we recommend you use HDMI 2.1 cables for better performance.

Next, verify if the source device, like a set-top box, is working properly. There can be cases when the video processor of the source device stops working and starts showing a green screen on TV. You can try restarting the source device and see if it fixes the problem. To verify if there is a problem in the source device or the TV itself, you can take the source device to another TV and check it there.

Troubleshoot HDMI Ports

Most of the source devices today use HDMI interface to establish a connection with your TV. So, if anything goes wrong with the HDMI port or HDMI module of your TV, it can show a green screen.

TV manufacturers like Samsung integrate a HDMI troubleshooting function that helps diagnose if there are anyissues in the HDMI connection. Here’s how to run HDMI troubleshooter on aSamsung 4 Series TV.

Check HDCP Compliance Issues

If you are facing green screen problems while watching only certain TV channels or contents, there is possibly an HDCP compliance issue. Most of the contents today are protected by HDCP (High-bandwidth Digital Content Protection) with the aim of reducing piracy and illegal distribution of contents.

To watch the contents that are protected by HDCP protocol, all the devices on your TV system must support it. To be more precise, the TV, the source device and the HDMI cable all must support it.

HDCP authentication uses a special encryption key called KSV (Key Selection Vector) that helps the receiver recognize the HDCP from the source device. The modern TVs and source devices do support HDCP. But, if the HDMI cables are not HDCP compliant, they can not transmit the key that can lead to an error. So, you must get a certified HDMI cable that supports HDCP to resolve the problem.

Re-configure Color Settings

If your TV screen is displaying more green color than other colors, you have probably set the wrong color settings. The misconfigured Hue or Tint (G/R) settings are mainly responsible for making your TV screen greenish. You can check it and adjust them appropriately.

Meanwhile, if the RGB settings are adjusted such that the green pixel values are higher, you may encounter green screen problems.

Troubleshoot Display Components

TVs mainly utilize red, green and blue pixels to form images on the screen. The green screen problem can arise if the red and blue pixels are dead and only the green pixels are glowing. So, if you remember any physical damage to the TV, this is the most probable scenario. There is no option exceptreplacing the broken screen of your TV.

However, there is also a DIY (Do It Yourself) method that may help solve the problem. You can try pressing the edges of your TV from where the green lines generate. If your entire TV screen is green, gently apply a pressure to each and every corner of your screen. You can take a soft cloth and try rubbing across the screen for a few minutes. Then, see if the green screen goes away.
