(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

-  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)

(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.

(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.
