(1) Enter the adjustment mode of DDC
- Set command delay time : 50ms
- Enter the DDC adjustment mode at the same time heat-
run mode when pushing the power on by power only key
- Maintain the DDC adjustment mode with same condition
of Heat-run (Maintain after AC off/on in status of Heat-run
pattern display)
(2) Release the DDC 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.
- Check DDC adjust mode release by exit key and release
DDC adjust mode
(3) Enter the adjust mode of white balance
- Enter the white balance adjustment mode with aging
command(F3, 00, FF)
* Luminance min value is 200cd/m
7-4. Adjustment of White Balance
(for Manual adjustment)
(1) Adjustment mode : Two modes (Cool and Warm)
(Medium data is automatically calibrated by the Cool data)
(2) Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000(LCD : CH9, PDP : CH10)
(3) Operate the zero-calibration of the CA100+ or CA-210,
then stick sensor to the module when adjusting.
(4) For manual adjustment, it is also possible by the following
sequence.
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 may be different.)
2) Push "Exit" key.
3) Change to the AV mode by remote control.(Push front-
AV or Input key)
4) Input external pattern(85% white pattern)
5) Push the ADJ key two times (entering White Balance
mode)
6) Stick the sensor to the center of the screen and select
each items (Red/Green/Blue Gain and Offset) using
D E
/ (CH +/-) key on R/C.
7) Adjust R/ G/ B Gain using F/G(VOL +/-) key on R/C.
8) Adjust two modes (Cool and Warm)
(Fix the one of R/G/B and change the others)
9) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
* CASE
First adjust the coordinate far 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

2 ≥ in the cool mode (For LCD)
(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
