I just installed another wei-ya chassis on an old WG monitor. The monitor powers up and has a clear picture, but i cannot get the color right no matter what i do. I have tried adjusting all the colors, and no matter what i do ms pacman is purple. The first maze is pink, like it should be, the dots are white, but she is purple. On galaga, most of the bugs look good, but the main bugs that beam you up, they are off color, the green/blue they turn is off. Is this the mark of a bad tube, or am i missing something.
