12-5. 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.(PDP : CH10)
- Operate the zero-calibration of the CA-110 or CA-210, then
stick sensor to the module when adjusting.
- For manual adjustment, it is also possible by the following
sequence.
(1) Select RF no signal by pressing "POWER ON" key on
remote control for adjustment then operate heat run more
than 15 minutes.
(If not executed this step, the condition for W/B will be differ.)
(2) Changing to the av mode by pushing the input or front av
key.(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
on R/C.
(5) Adjust R Gain / B Gain using
(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
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.
3) x > target , y < target
(1) First decrease B, so make y a little more than the
(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
(2) Adjust x value by decreasing the G.
(7) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
13. Input the Shipping Option Data
(1) Push the ADJ key in a Adjust Remote control.
(2) Input the Option Number that was specified in the BOM,
into the Shipping area.
(3) The work is finished, Push
