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
Need to transmit the aging off command to TV set after finishing the adjustment.

Adjustment of White Balance
(For Manual adjustment)
Adjustment mode : Two modes of Cool (Dynamic) and Warm(Mild) (Medium data is automatically calibrated by the cool data)
Color analyzer(CA110, CA210) should be used in the calibrated ch by CS-1000.(LCD : CH9)
For manual adjustment, it is also possible by the following sequence
Operate the zero-calibration of the CA-110 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 15 minutes. (If not executed this step, the condition for W/B will be differ )
(2) Changing to the av mode by remote control.(av mode : av1 or av2 or av3)
(3) Display the internal pattern of the VCT-Pro IC by pushing the IN-START.
(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 two modes of Cool(Dynamic) and Warm(Mild) as below figure. (Fix the one of R/G/B and change the others)
1) Push the one time the in-start key : Dynamic(Cool)
2) Push the two more the in-start key : Mild(Warm)
(For Manual adjustment)

(6) Adjust two modes of Cool(Dynamic) and Warm(Mild) as below figure. (Fix the one of R/G/B and change the others)
1) Push the one time the in-start key : Dynamic(Cool)
2) Push the two more the in-start key : Mild(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).
x,y > target
1) Decrease the R, G.
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
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
CASE
First adjust the coordinate much away from the target value(x, y).
x,y > target
1) Decrease the R, G.
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
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
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.
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.
