3-2. CONVERGENCE
If the blue dot does not converge with the red and green dots,
perform the following:
Before starting convergence adjustments:
1. Move BMC magnet (a) to correct insufficient H. Static
convergence.
1. Perform FOCUS, V.LIN AND V.SIZE adjustments.
2. Set BRIGHTNESS control to minimum.
2. Rotate BMC magnet (b) to correct insufficient V. Static
convergence.
3. Feed in dot pattern.
3. In either case, repeat Beam Landing Adjustment.
Vertical Static Convergence
PURITY
1. Adjust V.STAT magnet to converge red, green and blue
dots in the center of the screen (vertical movement).

Dynamic Convergence Adjustment
Before performing this adjustment, perform Horizontal
and Vertical Static Convergence Adjustment.
