288.1.3. White balance adjustmentName of measuring instrument RemarksColor analyzer(Minolta CA-100 or equivalent)Note:The CA-100 which was calibrated to less than +-0.001 with CS-1000.Procedure Remarks• Make sure the front panel to be used on the final set is fitted.• Make sure a color signal is not being shown before adjustment.• Put the color analyzer where there is little color variation.1. Set to Service mode menu, WB-ADJ.2. Select [VIVID] for picture menu.3. Select [Cool] for color temperature.4. Push [5] key of remote controller to display window pattern.Confirm the brightness within 10 seconds. The following is the confirmation value.TC-P42C2 252cd/m2In the case of NG for the measurement of the brightness, display black pattern for 30 seconds from turning onthe TV set, and after that, display the brightness check pattern and measure the brightness within2 minutes again.5. Set [R-CUT] [G-CUT] [B-CUT] the values written in table 1.6. Attach the sensor of color analyzer to the center of window pattern.7. Fix G drive at C0h and adjust [B-DRV] and [R-DRV] so x, y value of color analyzer become the [Color temperatureHigh] in table 2.8. Increase RGB together so the maximum drive value in RGB becomes [FF].That is, set [ALL DRIVE] to [FF].Execute adjustment again. When that, the maximum value of R/G/B DRV should be [FF], and either R/G/B DRVshould be [FF].Note:(Note) In procedure 7, all description of data [FF] should be treated as data [FC] when the model isS2/C2/U2/X2 and manual adjustment is performed by service mode menu.9. The average of the adjusted values in color temperature Cool, Mid, and Warm is shown in Table 4.The setting value for color temperature Mid will be calculated by multiplying the adjusted value of color tempera-ture Cool to the ratio of the value of Cool and Mid in each GBR value in Table 4.Write that values to the data area of color temperature Mid in EEPROM (Table 3).10. The setting value for color temperature Warm will be calculated by multiplying the adjusted valueof color tempera-ture Cool to the ratio of the value of Cool and Warm in each GBR value in Table 4.Write that values to the data area of color temperature Warm in EEPROM (Table 3).Note :Adjusted valuemust be written toboth SD data areaand HD data areaof the EEPROM.
