Visual Procedure For Color Decoder:
You need color test patterns like those found on AVIA to set the color decoder
properly. Use only the blue LCD panel and the blue pattern to set color and hue,
the green pattern and LCD panel is used to set GYR & GYB, the red pattern and
LCD panel is used to set RYR & RYB. To switch the panels on and off use RGBS
in category 2170P-2.
The colored filters can also be used, but the green with Avia is much less
accurate than switching the panels. You need to view a display like THX
Optimode for setting picture level and increase SPIC only to the point where the
light grays do not shift in color.
Light Meter Procedure For Color Decoder:
Use the special Avia color bar pattern with the 77 IRE white bar below each color bar
and the blue and red filters included with Avia. This minimizes the shift in brightness
caused by a change in horizontal position.
Use the blue filter to set the adjustments for blue. The filter should be between the
light meter and the screen with the sensor pressed up to the screen. Set the level of
blue to match the level of blue in white with the COLOR adjustment. Then adjust
HUE by measuring the level of blue in cyan and magenta and match them to the
level of blue in white.
Next, use the red filter to set the color decoder for red. Adjust RYR (red level) by
setting the red bar intensity to match the white bar with the red filter. Adjust RYB
by setting the red level in yellow and magenta to match that in white.
Green requires a different method because the color filters are inadequate for that
primary. The color bars should follow the following intensity pattern for NTSC relative
to white:
•
White 1.0
•
Yellow 0.866
• Cyan 0.701
• Green 0.587
• Magenta 0.413
• Red 0.299
• Blue 0.114
HD should follow the following pattern if you had a test pattern:
•
White 1.0
• Yellow 0.9279
• Cyan 0.7875
• Green 0.7154
• Magenta 0.2846
• Red 0.2125
• Blue 0.0721
