    Vizio E500i-A1 Monochrome (black & white) image

    Hello, I have a very weird issue with my Vizio E500i-A1. It works well except it only shows monochrome (black & white) image. TV signal is b&w, all HDMI inputs are b&w. At the same time the TV menu is colorful. Of course I tried to change color/saturation settings, it doesn't have any effect.
    I tried to do factory reset. The TV setup screen was colorful, however it didn't help, all inputs are still showing b&w picture.
    Checked voltatges on MB and all seem to be fine.
    UPDATE: tried to play an .avi file via a built-in media player. The media player menus are colorful, but the video itself is b&w O_O

    Any ideas please?

    Tried erasing eeprom, it doesn't turn on this way...
    This is clearly a software problem, can anyone help to find the eeprom dump for it?
