(3) ACT Gain and Phase is variable and the Tartan plaid of R,
G, B, W Horizontal Line adjust not distinguished not to be.
a. The Phase(Base value : 220) variable adjust
Mutation point of Actuator.
b. The Gain(Base value : 70) adjust mutation quantity of
Actuator.
* The Tartan plaid of R, G, and B adjust not visible not to
be. But, when the R, G and B will not agree, adjust with
point R and G agree.
(4) Using the Service Remote Control, enter from ADJ to
Actuator_50Hz.
(5) ACT Gain and Phase is variable and the Tartan plaid of R,
G, B, W Horizontal Line adjust not distinguished not to be.
a. The Phase(Base value : 165) variable adjust
Mutation point of Actuator.
b. The Gain(Base value : 47) adjust mutation quantity of
Actuator.
* The Tartan plaid of R, G, and B adjust not visible not to
be. But, when the R, G and B will not agree, adjust with
point R and G agree.
Before Actuator Adjustment

13. CWI / NDC Adjustment
(Base value --> CWI: 160, NDC: 12)
7 segment Color wheel - CWI : 160, NDC : 12
6 segment Color wheel - CWI : 100, NDC : 0
- 6 segment Color wheel admits 4,500EA only for inventory
reduction.
1) Required Test Equipment
: Remote control
2) Preparation for Adjustment
(1) Connect power and turn Power on.
(2) Using the Remote Control, enter from ADJ to CWI/ NDC.
<Fig 12. Test Pattern>
After Actuator Adjustment
3) Adjustment
(1) Using the Channel key, adjust CWI-Pat.1 to the LEFT/
RIGHT
(2) As adjustment, check the appearance noise in the
TEST Pattern<Fig 12>.
Setting the value reduced (3)~(4) step at a GREEN noise
disappearing spot.
* Intermediate value the point Green color disappears from
the Ramp Pattern and the point bottom color purity
comes to be uniform from the RED Pattern is same
(3)~(4)-step with value Green color disappears from the
Ramp Pattern.
(3) Using CH UP/DOWN key of the Remote Control, enter
the RED PATTERN.
(4) Check the RED Pattern<Fig 13> to uniform. After
checking unless abnormality do OK.
<Fig 13. RED Test Pattern>
4) NDC Adjustment
For compensation deviation of each Lamp uses NDC
Mode.Sees the Pattern and adjust left/right value using
Channel Key on Remote Control for Adjustment to be
uniform color of the White. (Lamp life compensation)

Adjusting the Auto CCA
1) Required Test Equipment
: CA-210
2) Adjustment Sequence
(1) Install the equipment(CA210) be 5cm away from screen
center.
(2) RS-232C cable is connected from Control PC in the SET.
(3) Measure is started in the statement that SET is done to
Heat Run.
