There might be something wrong with the blue gun, or something wrong with the mechanism which drives the blue gun. In the additive color system, red+green = yellow, so if the blue is less intense, in general, than it should be the yellow would become more prominent. If it's the gun, itself, you'll probably be getting a nice new LCD monitor. . . . . . . . . . . . . . . . . . . . . . . O'Brien
