3 Adjustment
3.1. PAL panel white balance adjustment
Instrument Name Connection Remarks
· W/B pattern (PAL-M or NTSC signal)
· Color analyzer (Minolta CA-100 or equivalent) RF input
Panel surface User setting: Normal
Procedure Remarks
· Asing time is longer than 15min.
· 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 colour variation.
Complete the adjustment within 10 minutes after the turn on electricity.
Turn on the power supply again when it is not possible to complete it by aging etc.
1.Display the white balance pattern.
2.Check that the color balance is “cool”.
3.Enter the <Service1> mode.
4.Select “G-CUTOFF” item, using the color-key “Red” or “Green”, and set to “128”, using the
color-key “Yellow” or “Blue”.
Also, “B-CUTOFF” and “R-CUTOFF” set to “128”.
5.Set “G-DRIVE” at “224”.
6.Touch the signal receiver of color analyzer to the highlight window’s center, and adjust B
drive and R drive so x, y become the “Color balance Cool” in the below table.
7.Set “ALL-DRIVE” to “252”.
8.Set colorbalance to “Normal”.
9.Fix G cutoff , B cutoff and R cutoff at “128”.
10. Fix G drive at “224”.
11. Adjust B drive and R drive so the highlight window’s x, y become the “Color balance
“Normal” in the below table.
12. Set “ALL-DRIVE” to “252”.
13. Set color balance to “Warm”.
14. Set G cutoff, B cutoff and R cutoff to “128”.
15. Set G drive to “224”.
16. Adjust B drive and R drive so the highlight window’s x, y become the “Color balance Warm”
shown in the below table.
