Question 9

How to fix the green display on all HDMI inputs of the JVC LT-32FV140 TV?

Accepted Answer

If your JVC LT-32FV140 displays a green screen on all sources (HDMI, antenna, USB), it is generally related to color or saturation settings. Here’s how to fix this issue:

1. Adjust saturation and color

Access the MENU > Picture menu and check the following settings:

Color saturation - Reduce it to around 50-60 (scale 0-100) to see if this eliminates the excess green
Color temperature - Test the different modes: Warm1, Warm2, Standard, or Cool
Brightness and Contrast - Ensure they are not set to extreme values

2. Disable adaptive contrast

Still in MENU > Picture, locate Adaptive Contrast and set it to Off (Disabled). This function automatically adjusts dark and light areas, which can sometimes amplify a color shift.

3. Test predefined picture modes

The JVC LT-32FV140 has several picture modes: Standard, Day Cinema, Evening Cinema, Dynamic, Sports, Game Mode. Try the Standard or Day Cinema mode to see if the problem disappears. If so, you can adjust the settings in the mode that works.

4. Reset picture mode

If no adjustment helps, go to MENU > Picture and look for the Reset current mode option. This restores the factory settings of the selected mode and may correct an accidental color shift.

5. Rare case: hardware issue

If the green screen persists after all these adjustments and on all sources, you may be experiencing an HDMI wiring issue or a defect in the video processing module. Check that the HDMI cables are securely connected and try different cables if available.
