Never try to correct this misalignment with the shift correction or the static convergence controls. These shift
correction controls may only be applied to correct small errors which cannot be corrected by the CRT angle
adjustment. The Horizontal Shift and Vertical Shift for Red and Blue should be set near 50%.
Be sure that the rasters are centered on the CRT faceplate.
