3-2. CONVERGENCE
(1) Horizontal and vertical Static Convergence Adjustment
on the Center of Screen.
Before starting, perform Y. SIZE, Y. CENT, H.SlZE, H.CENT
and Screen Distortion Adjustment rightly.
(Static Convergence Adjustment)
I. Receive a dot signal, setting BRIGHTNESS minimum and set
CONTRAST to normal.
2. Adjust H.STAT YR to coincide red, green and blue dots on the
center of screen. (Horizontal movement)
3. Adjust Y .ST AT magnettocoincide red, green and blue dots on the
center of screen. (Vertical movement)

If the red, green and blue dots do not coincide on the center of
screen with H.ST AT YR, perform adjustment using Y .STAT at
the same time while tracking.
(Tilt the
Y .ST AT magnet and adjust static convergence to open or
close the Y.ST AT magnet.)
