Power Saving Test; Dcc 1/2B Test - NEC N9902 F-1 Service Manual

(C) Contrast control set to Max and brightness control set to the center, adjust R.G.B. GAIN
standard as below
9300K x = 0.283 + 0.010
y = 0.297 + 0.010
Y = 155 + 5 cd/m²
7500K x = 0.300 + 0.010
y = 0.315 + 0.010
Y = 155 + 5 cd/m²
6500K x = 0.315 + 0.010
y = 0.325 + 0.010
Y = 155 + 5 cd/m²
(D) PATTERN: FULL WHITE 9300K.
(E) If they are out of spec, adjust to following:
BRIGHTNESS: Back raster is 0.2 cd/m² position
CONTRAST MAX: (MAX-5 digit )~(MAX)
Adjust R/G/B gain to be 9300K color due to about spec.
(F) When adjust 6500K and 7500K color¡Akeep brightness and contrast max position to (E)
condition. Adjust R/G/B/ GAIN to be 6500K color due to about spec..
(G) Adjustment: Brightness control and contrast control set to Max, adjust VR303 to
Y=29~31FT-L(103+3cd/m²)
