3-2. CONVERGENCE
Preparation:
@ Before starting, perform FOCUS, H.SIZE, and V.
SIZE adjustments.
@ Set BRIGHTNESS control to minimum.
@ Feed in the dot pattern.
(1) Horizontal and Vertical Static Convergence
RV 704 B-DRIVE
RV 703 G-DRIVE
RV 702 H.STAT
RV 701 SCREEN
1. Adjust H.STAT VR to converge red, green and blue
dots the in center of the screen.(Horizontal move-
ment)
2. Adjust V. STAT magnet to converge red, green and
blue dots in the center of the screen. (Vertical move-
ment)
3. If the red, green and blue dots do not converge on
the center of screen with H.STAT VR, perform
horizontal convergence adjustment using H.STAT
VR and V.STAT magnet as shown below. (In this
case, H.STAT VR and V.STAT magnet effect each
other.)
@ Tilt the V.STAT magnet and adjust static conver-
gence to open or close the V.STAT magnet.
4.When the V.STAT magnet is moved in the
direction of arrow @ and ®, red, green and blue dots

If the red and blue dot do not converge with green
dots, perform following steps.
Move BMC magnet (a) to correct insufficient H.static
convergence.
Rotate BMC magnet (b) to correct insufficient V.static
convergence.
In either case, repeat Beam Landing Adjustment.
