-  Maintain  the  white  balance  adjustment  mode  with  same
condition of Heat-run 
- Maintain after AC off/on in status of Heat-run pattern display
(2) Release the white balance adjustment mode
-  Release  the  adjust  mode  after  AC  off/on  or  std-by  off/on  in
status of finishing the Hear-run mode
-  Release  the  Adjust  mode  when  receiving  the  aging  off
command(F3 00 00) from adjustment equipment)
(3) Enter the adjust mode of white balance
-  Enter  the  white  balance  adjustment  mode  with  aging
command(F3, 00, FF)
9-4. Adjustment of White Balance for 
Manual Adjustment
(method 3) 
Adjustment  mode:  Three  modes  of  Cool,  Medium(Vivid)  and
Warm
- Equipment : 1) Color analyzer(CA100+, CA210) should be
used  in  the  calibrated  ch  by  CS-1000(PDP  :
CH10)
2) Adjustment remocon
-  For  manual  adjustment,  it  is  also  possible  by  the  following
sequence.
Operate the zero-calibration of the CA-100+ or CA-210, then
stick sensor to the module when adjusting.
(1) Select white pattern of heat-run by pressing “POWER ON”
key on remote control for adjustment then operate heat run
longer than 5 minutes. (recommend) 
(If  not  executed  this  step,  the  condition  for  W/B  will  be
different)
(2)  Changing  to  the  AV  mode  by  remote  control.(Push  front-
AV)
(3) Input external pattern(85% white pattern).
(4) Stick sensor to center of the screen and select each items
(Red/Green/Blue  Gain  and  Offset)  using 
D
/
E
(CH  +/-)  key
on R/C..
(5) Adjust R/ G/ B Gain using 
F
/
G
(VOL +/-) key on R/C.
(6)  Adjust  three  modes  of  Cool,  Medium(Vivid)  and  Warm  as
below figure.
(Fix the one of R/G/B and change the others)
- Push the “VOL + “ key : Cool, Medium, Warm
[ Refer to the below case to know what value is fixed.
[CASE]
First adjust the coordinate much away from the target value(x, y).
1. x, y > target
1) Decrease the R, G. 
2. x, y < target
1) First decrease the B gain, 
2) Decrease the one of the others.
- In case of decreasing the x, decreasing the R : fix G
- In case of decreasing the y , decreasing the G : fix R
3. x > target ,  y < target
1) First decrease B, so make y a little more than the target.
2) Adjust x value by decreasing the R
4. x < target ,  y > target
1) First decrease B, so make x a little more than the target.
2) Adjust x value by decreasing the G
(7)  When  adjustment  is  completed,  Exit  adjustment  mode
using EXIT key on R/C.
9-5. Connecting diagram of Equipment for 
Measuring
(For Automatic Adjustment) 
(method 1, using IIC, You connect RGB Cable)
(1) Enter the adjustment mode of the white balance
- Enter the white balance adjustment mode at the same time
heat-run  mode  when  pushing  the  power  on  by  power  only
key
-  Maintain  the  white  balance  adjustment  mode  with  same
condition of Heat-run 
- Maintain after AC off/on in status of Heat-run pattern display
(2) Release the white balance adjustment mode
-  Release  the  adjust  mode  after  AC  off/on  or  std-by  off/on  in
status of finishing the Hear-run mode
-  push  the  “power  on”  key(IIC  Mode)  on  Adjust  remote-
controller.
-  Release  the  Adjust  mode  when  receiving  the  aging  off
command(F3 00 00) from adjustment equipment)
(3) Enter the adjust mode of white balance
-  Enter  the  white  balance  adjustment  mode  with  aging
command(F3, 00, FF)
O
Color Temperature & Color Coordinates Setting
-  When  adjusting  the  Color  Temperature,  Color  Analyzer  CA-
210(Matrix  should  be  corrected  through  CH10  of  CS-1000)
should be used. When CA-210 have used, it don’t need to fit
the CH10.
-  Adjust  the  Color  Temperature  based  below  adjustment  color
coordinates.
