RED/GREEN/BLUE FORMATTER CONVERGENCE ADJUSTMENT
NOTE: Do not apply excessive force on the adjustment screws. This might cause the convergence
adjustment to become misaligned once you remove the adjustment tool.
The Red and Green Formatters are identical in physical layout and adjuster function. The Blue
formatter board is slightly different in physical layout, but the adjustment functions are the same. The
vertical and twist adjustments (Screws 1 and 2) interact with each other, while the horizontal
adjustment (Screw 3) is indpendent, as described in (Figure 7).
Figure 7 Red/Green/Blue Formatter Convergence Adjustment
The physical layout of the Formatter boards dictates the behavior of the Twist and Vertical
adjustments:
• The adjustment of the twist and vertical is more like a "Twist with the left-side of the screen as a
sliding hinge point to allow vertical travel".
