Before making adjustments, check that the video
signals are as follows:
Video : Analog, 0.7 Vp-p (at 75 ½ termination)
Sync : Separate TTL level
Unless otherwise specified, use 800 x 600 mode
signal (53.7 kHz/85 Hz) for adjustments.
5-3-1 Color Coordinates (Temperature)
Color temperature is a measurement of the
radiant energy transmitted by a color. For
computer monitors, the color temperature refers
to the radiant energy transmitted by white. Color
coordinates are the X and Y coordinates on the
chromaticity diagram of wavelengths for the
visible spectrum.
CONDITIONS
Measurement instrument: Color analyzer
Scanning frequency:
53.7 kHz/85 Hz
Display image:
White flat field at
center of display area
Luminance:
Maximum
PROCEDURE
Using the directions in sections 5-3-2 through
5-3-5, adjust the Color Coordinates for 9300K to
x = 0.283 ± 0.02 and y = 0.298 ± 0.02
5-3-2 Back Raster Color Adjustment
CONDITIONS
Measurement instrument: Color analyzer
Scanning frequency:
53.7 kHz/85 Hz
Display image:
Back raster pattern
Brightness:
Maximum
Contrast:
Maximum
PROCEDURE
1. Adjust the Screen VR on the FBT so that the
brightness of the Back Raster is 0.3 to 0.5 ft-L
(typically 0.4 ft-L).
2. Adjust the G_CUT to center.
3. Adjust the B_CUT to set the ÒyÓ coordinate to
0.298 ± 0.02.
4. Adjust the R_CUT to set the ÒxÓ coordinate to
0.283 ± 0.02.
Note:
If the above adjustments cannot be done to
each coordinate, adjust G_CUT to increase
or decrease the green cutoff and repeat
procedures 3 and 4.
5-3-3 Video Gain Adjustment

CONDITIONS
Measurement instrument: Color analyzer
Scanning frequency:
53.7 kHz/85 Hz
Display image:
Green box pattern
within range for which
the ABL circuit is not
active (1/3 to 1/2H and
1/3 to 1/2V).
Brightness:
Maximum
Contrast:
Maximum
PROCEDURE
1. Adjust G-Gain so that the brightness of the
green gain is 40 ± 1 ft-L
(typically 40 ft-L).
