the center of the screen. Make R and B almost
identical. (Fig. 2-1)
6. Switch to B only, R only, and G only and verify each.
7. Bring the deflection yoke gradually forward and adjust
the deflection yoke so that R and B on both sides of
the screen will be green. (Fig.2-2 → Fig. 2-3)
8. If the deflection yoke comes forward too much, the
pattern shown in Fig.2-4 will appear. If so, move the
deflection yoke backward. (Fig.2-4 → Fig.2-3)
9. Switch the signal generator output signal to the BLUE
only color and confirm the screen. (Fig. 2-6)
10. Switch the signal generator output signal to the RED

11. When two colors are mixed, set the mixed color as the
standard, and repeat operations 6 and 7.
12. Switch to an all-white signal and check the uniformity.
13. When the deflection yoke position is determined,
fasten it with the DY screw.
