In a typical T&B, the left 4 colors have the green gun on.
Without green, I think it would be purple red blue black, then that again (at least with the bars I make for color testing)

Primary colors of light = Red, Green & Blue = white.
Red & Green = Yellow
Green & Blue = Cyan
Red & Blue = Magenta
The OP's TV screen is magenta, which means there's no green in the picture. (Or there is some green, but not enough to equalize the color.) Could be a bad gun. Could be the cooling fluid needs to be replaced. Could be an electronic issue. Start by making sure the gun isn't working.
