3.4.3 Red/Green/Blue Formatter Convergence Adjustment Description
Remove all jewelry (rings, watches, necklaces, bracelets etc.) before adjusting convergence.
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 work together on the horizontal axis, as described in
Figure 3-10 .
Figure 3-10 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 two is more like a “Twist with the left-side of the screen as a sliding hinge point to
allow vertical travel”.
• The vertical adjustment screw and twist adjustment screw interact with each other such that if one is turned
in the opposite direction of the other, the twist is affected.
• If both screws are turned equal amounts in the same direction, the image moves vertically.
