Why Is My TV Screen Green?

When a TV screen is green, it means that either the TV is not receiving any kind of video feed or there is an over-saturation of green. If the screen is completely green, then it is due to the fact that the TV is not receiving any input. If there are pictures on the screen but the whole picture has a green hue, it is due to an over-saturation.

If the screen is completely green, the first course of action is to check the video source for the television. Users should make sure that the TV is checking for the video feed from the correct source. For example, if the TV is hooked up to a cable box via an HDMI cord, the user needs to make sure that the TV is turned to an HDMI source. Some TVs have multiple HDMI sources, so it is sometimes necessary to check all of the sources to figure out which one the cable box is plugged into.

If the TV screen has a green hue but a picture is still being presented, the problem is due to the over-saturation of the color green. To fix this, a user goes into the picture menu on the TV and looks for the saturation option. Once it is located, the user turns down the green coloring until the picture looks normal again.
