the INSTART key twice (White Balance) on R/C.
3) Stick  sensor  to  center  of  the  screen  and  select  each
items using  
D/E
(CH +/-) key on R/C.
4) Adjust G Gain / B Gain using  
F/G
(VOL +/-) key on R/C.
5) Adjust it until color coordination becomes as below. 
- By controlling G, B GAIN, adjust X, Y target value. 
- R Gain fixed at cool, normal, warm mode.
- But, Control the R GAIN, unless it has correct value
(Initially, R/G/B gain and R/G/B offset values are fixed as below.)
Red Gain: 80h
Green Gain:  80h Blue Gain: 80h
Red Offset: 80h
Green Offset: 80h Blue Offset: 80h 
*Target value
6) When  adjustment  is  completed,  Exit  adjustment  mode
using EXIT key on R/C.
