9. Adjustment of White Balance
9-1. Purpose and Principle for adjustment
of the color temperature
(1) Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
(2) Principle : To adjust the white balance without the
saturation, Fix the one of R/G/B gain to 80 and decrease
the others.
9-2.Adjustment mode
: Two modes of Cool and Warm.(Medium data is
automatically calibrated by the cool data)
9-3. Required Equipment
(1) Remote control for adjustment.
(2) Color Analyzer : CA-100+, CA210 or same product.
- Plasma TV(ch : 10)
(3) Auto W/B adjustment instrument.(only for Auto adjustment)
9-4. Connecting diagram of equipment for
measuring 
(For Automatic Adjustment)
(1) Enter the DDC adjust mode.
- 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 DDC adjust 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.
* Standard color coordinate and temperature when using the
CA-100+ or CA210 equipment.
* Synchronization relation between PSM and CSM.
(3) DDC adjustment support command set.
* R/G/B GAIN max value : 80
9-5. 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
/
(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.
10. Default Value in Adjustment mode

(2) DMM.
13-3. Connection Diagram for Measuring
: refer to (Fig. 1)
13-4. Adjustment Method
(1) Va Adjustment
1) After receiving 100% Full White Pattern, HEAT RUN.
2) Connect + terminal of D. M..M. to Va pin of P812, connect

3)  After turning VR901,voltage of D.M.M adjustment as
same as Va voltage which on label of panel right/top.
(deviation; 
±0.5V)
(2) Vs Adjustment
1) Connect + terminal of D. M..M. to Vs pin of P812, connect
-terminal to GND pin of P812.
2)  After turning VR851, voltage of D.M.M adjustment as
same as Vs voltage which on label of panel right/top.
(deviation ; 
±0.5V)
14. 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.
