Yellow is the lack of blue. It can happen when you are running your contrast - which is your overall light level - too high.
Try turning down your contrast. On CRT tech, contrast should always be run at half what the factory allows as full, on the user controls. Full up is what calibrators call Torch Mode, and is NOT the way to get performance to be in the linear operating range of CRT tech.
If your sides are more yellow than your middle, your set may need lenstriping. Mild yellow on the sides is not uncommon, and usually not noticed. But heavy yellow on the sides would indicate that the blue image needs work on white field uniformity.
