Notes:
• Perform the following adjustments after completing the Low-Light White Balance (Reference Value) Adjustment.
• Set the COLOR TEMP./BAL. data in the Setup Menu to “00”.
• The values adjusted with WX become the reference values for the following adjustment. When this data is changed,
it is required to re-adjust the white balance data of all of the adjustment signals (Component, NTSC and PAL).
When re-adjusting the 1080/60i signal, use the WJ.
(1) Apply the 1080/60i component 10-step gray scale signal to INPUT A.
(2) Set “COLOR TEMP.” of COLOR TEMP./BAL. in the Setup Menu to LOW.
(3) Set the PHASE, CHROMA, BRIGHT and CONTRAST potentiometers on the front panel to the center click positions.
(4) Adjust WX01 and WX03 in the Service Menu using the color temperature meter so that the color temperature is set as shown
below.
(Do not touch WX02.)
Color temperature: LOW (D65). x = 0.313, y = 0.329 (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 WX04 to WX06 to correct it.
(Do not set the values of WX04 to WX06 no more than “50”.)
(6) Vary the adjustment signal and adjustment data, and re-perform adjustments in steps 1 to 5 above (see Table 19).
