Notes: • Perform the following adjustments after completing the Low-Light White Balance Adjustment.
• Set the COLOR TEM./BAL. data in the Setup Menu to “00”.
• The values adjusted with WO 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 WI.
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 HIGH.
3. Set the PHASE, CHROMA, BRIGHT and CONTRAST potentiometers on the front panel to the center click positions.
4. Adjust WO01 and WO03 in the Service Menu using the color temperature meter so that the color temperature is set as shown below.
(Do not touch WO02.)
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 WO04 to WO06 (Low-Light) to correct it.
(Do not set the values of WO04 to WO06 no more than “50”.)
6. Vary the adjustment signal and adjustment data, and re-perform adjustments in steps 1 to 5 above (see Table 18).
