8. Adjustment of White Balance
Caution: Press the POWER ON KEY on R/C before W/B adjustment.
8-1. Test Equipment
- Color Analyzer (CS-1000, CA-100+(CH.10), CA-210(CH.10))
[ Please adjust CA-100+ / CA-210 by CS-1000 before measuring
--> You should use Channel 10 which is Matrix compensated
(White, Red, Green, Blue revised) by CS-1000 and adjust
in accordance with White balance adjustment coordinate.

8-2. Connecting Picture of the Measuring 
Instrument
(On Automatic control )
Inside PATTERN is used when W/B is controlled. Connect to
auto  controller  or  push  control  R/C  ADJ  Key—>  Enter  the
mode of White-Balance, the pattern will come out.
8-3. Auto-control Interface and Directions
(1)  Adjust  in  the  place  where  the  influx  of  light  like  floodlight
around is blocked. (illumination is less than 10ux).
(2) In case of PDP: Measure and adjust after sticking the Color
Analyzer (CA-100+, CA210) to the side of the module. 
In  case  of  LCD:  Adhere  closely    the  Color  Analyzer  (
CA210)  to  the  module  less  than  10cm  distance,  keep  it
with the surface of the Module and Color Analyzer’s Prove
vertically.(80~100°).
(3) Aging time  
1)  After  aging  start,  keep  the  power  on  (no  suspension  of
power supply) and heat-run over 15 minutes.
2) In case of PDP, keep white pattern using inside pattern.
3) In case of LCD, using ’no signal’ or ‘full white pattern’ or
the others, check the back light on.

8-4. Manual White Balance 
(1)  Press  the  POWER  ON  KEY  on  R/C  for  adjustment  and
heat run over 5 minutes.
(2)  Zero  Calibrate  CA-100+  /  CA-210,  and  when  controlling,
stick the sensor to the center of PDP module surface.
(3) Press the ADJ KEY on R/C and enter EZ ASJUST
Select “3.W/B ADJUST” and press ENTER(

)
Set test-pattern on and display inside pattern. 
(4) Control is carried out on three color temperatures, COOL,
MEDIUM, WARM.(Control is carried out three times)
<Temperature: COOL>
- R-offset / G-offset / B-offset is set to 128
- Control R-Gain and G-Gain.
- Each gain is limited to 192
<Temperature: MEDIUM>
- R-offset / G-offset / B-offset is set to 128
