(3) DDC adjustment support command set.
* R/G/B GAIN max value : 80
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 D / E (CH+/-) key
on R/C.
(5) Adjust R Gain / 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)
* 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.
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
A
Key.
14. Default Value in Adjustment mode
(Default values maybe modified the module condition)
14-1. White Balance
15. Internal press test
16. Sound spec.
