Steps
Remarks
[condition]
• 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.
[Adjustment]
1. Set COMPONENT / RGB-IN SELECT to COMPONENT.
2. Select the IIC mode “PANEL W / B Adj.” item.
3. Check that the color temperature is “COOL (Hi)”.
4. Output a white balance pattern.
5. Touch the signal receiver of color analyzer to the highlight window’s center.
6. Fix G drive at E0h and adjust B drive and R drive so x, y become the “Color temperature 
COOL (Hi)” in the below table.
7. Increase R / G / B together so the maximum drive value in R / G / B becomes FCh.
8. Set color temperature to “NORMAL (Mid)”.
9. Fix G drive at E0h and adjust B drive and R drive so the highlight window’s x, y becomes 
the “Color temperature NORMAL (Mid)” in the below table.
10. Increase R / G / B together so the maximum drive value in R / G / B becomes FCh.
11. Set color temperature to “WARM (Low)”.
12. Set G drive to E0h and adjust B drive and R drive so the highlight window’s x, y become 
the “Color temperature WARM (Low)” shown in the below table.
13. Increase R / G / B together so the maximum drive value in R / G / B becomes FCh.
14. Copy the R drive, G drive and B drive data in YUV1_525ip, YUV3_625ip region.
Adjustment target
Hi-light: x ± 0.003 y ± 0.003
Hi-light is target of the number at drive adjustment in the hi-light windows.
Therefore, it is not target of the hi-light number at after adjustment white balance.
