(h) Set the brightness control to the center and adjust the sub contrast control to get the screen
luminosity from 33Ft/L.
(i) Check if the x, y coordinates of color analyzer is in x=0.281±0.015, y=0.311±0.015.
If the color coordinates is out of range, adjust the R. G. B BIAS & GAIN to get the coorinates in
x=0.281, y=0.311. Make sure that the coordinates is in range by using contrast control.
7. Static Convergence Adjustment
(a) Apply a magenta cross hatch pattern on display.
(b) Adjust the focus from the best over all focus on the display.
Also adjust the brightness to the desired condition.
(c) Vertical red and blue lines are converged by varying the angle between the two tabs of the 4-pole
magnets.
(d) Horizontal red and blue lines are converged by varying the tabs together keeping the angle between
them constant.
(e) Apply a yellow cross hatch pattern on display.
(f) Vertical green and red lines are converged by varying the the angle between the two tabs of the 6-
pole magnets.
(g) Horizontal green and red lines are converged by varying the tabs together keeping the angle
between them constant.
