Notes:
•
Perform the following adjustments after completing the 1080/60i White Balance (High: D9300, Low: D65) Adjustments.
•
Set the COLOR TEMP./BAL. data in the Setup Menu to “00”.
•
The values adjusted with WW (see the description of the Component Signal White Balance (High: D9300) adjustment)
become the reference values for the white balance (high: D9300) adjustment. When this data is changed, it is required
to re-adjust the white balance (high: D9300) data of all of the adjustment signals (Component, NTSC and PAL).
•
The values adjusted with WX (see the description of the Component Signal White Balance (Low: D65) adjustment)
become the reference values for the white balance (low: D65) adjustment. When this data is changed, it is required to
re-adjust the white balance (low: D65) data of all of the adjustment signals (Component, NTSC and PAL).
<HIGH: D9300>
(1) Apply the NTSC 10-step gray scale signal to INPUT C (Terminal VIDEO1 of the NTSC/PAL Video Input Card).
(2) Set “COLOR TEMP.” of COLOR TEMP./BAL. in the Setup Menu to HIGH.
(3) Set the PHASE, CHROMA, BRIGHT and CONTRAST potentiometers on the front panel to the center click positions.
(4) Adjust
WA01
and
WA03
in the Service Menu using the color temperature meter so that the color temperature is set as shown
below.
(Do not touch
WA02
.)
Color temperature : HIGH (D9300). x = 0.283, y = 0.297 (Reference value)
(5) Ensure that the white balance tracking is correct from the gray scale steps with lower color temperatures to those with higher
color temperatures. If the white balance tracking is deviated in darker steps, adjust
WA04
to
WA06
to correct it.
(Do not set the values of
WA04
to
WA06
no more than “
50
”.)
<LOW: D65>
(1) Set “COLOR TEMP.” of COLOR TEMP./BAL. in the Setup Menu to LOW.
(2) Adjust
WB01
and
WB03
in the Service Menu using the color temperature meter so that the color temperature is set as shown
below.

Color temperature : LOW (D65). x = 0.313, y = 0.329 (Reference value)
(3) Ensure that the white balance tracking is correct from the gray scale steps with lower color temperatures to those with higher
color temperatures. If the white balance tracking is deviated in darker steps, adjust
WB04
to
WB06
to correct it.
(Do not set the values of
WB04
to
WB06
no more than “
