▪ After enter Service Mode by pushing "ADJ" key,
▪ Enter White Balance by pushing " ► " key at "9. White
Balance".
* CASE Cool Mode
First adjust the coordinate far away from the target
value(x, y).B.
1) x, y > target
2) x, y < target
3) x >target, y < target
4) x < target, y > target
- Every 4 case have to fit y value by adjusting B Gain
and then fit x value by adjusting R-Gain.
- In this case, increasing/decreasing of B Gain and R
Gain can be adjusted.
How to adjust
1) In case G gain more than 172
Adjust R Gain and B Gain less than 192
2) If the G gain value be adjusted down to 172
One of the R/B Gain is 254
3) If G Gain is 172 , More than one of R/B Gain is to be
between 192~254
