Is it a convergence problem or a color shift? How are you evaluating it?

You could have a g2 problem. These sets act funny with g2 adjustments that are off. More likely would be something in the scan velocity modulation where your edge focus is off. These kinds of problems can get messy to figure out. I have no easy solutions for your problem. It would take closer examination and troubleshooting. First thing to do is put up a cross hatch or dot pattern and check the edge focus vs the center.
