1. Receive 1080i/50Hz dot signal from HD/DVD 1 terminal.
2. Set “Hi Fine” and PICTURE 100%, other 50% and white

balance “COOL”. (VM OFF)

3. Blue 4 pole : make round in the center of screen.
4. Confirm that center dot focus is adjusted in focus. (Fig.3-12a)
5. Adjust blue electrical focus to make the left side spot nearly

round by minimizing width and height. (Slight overfocus is
OK) (Fig.3-12b)

6. Confirm that the green to blue spot size is within spec.

Blue center dot height shall be 

≤

 1.2 times the green dot heght.

7. Return making condition data to orignal data.

1. Input a cross hatch signal into VIDEO 1. (composite video

input)

2. Place a lens cover over red and blue lenses and project only

green.

3. Rotate the green lens and adjust to obtain the best lens focus at

the center area.

4. Fix lens screw.
5. Repeat above process for red and blue.

1. Input a cross-hatch signal into VIDEO 1.
2. Project only Green.
3. Rotate the green focus volume on the focus pack and adjust to

obtain the best focus at the center screen.

4. Repeat above process for red.

1. Receive the Dot signal (1080i/50Hz) from HD/DVD 1 termi-

nal.

2. Place the caps on the red and blue lens so that only the green

color is shown.

3. Turn the green focus volume of focus pack counter-clock-

wise, so that diameter of the dot become large.

4. Adjust the 2-pole magnet,  counter-clockwise and clockwise

center of the dot doesn't move. (Use focus volume)

5. Center position is changed by 2-pole magnet adjustment.

So, center magnet adjustment and 2-pole magnet adjustment
are needed tracking adjustment.

6. Repeat same adjustment method for red and blue.

1. Turn Grenn focus volume of focus pack clockwise.
2. By using 4 pole magnets make the spot size round.
3. Repeat for red and blue.
4. Turn focus pack counter-clockwise and “Just Focus” red,

green and blue.

1. Turn blue focus volume of focus pack counter-clockwise, so

that diameter of the dot becomes large, and can see bright core
position.

2. Pay attentio to left side dot of the screen. (Fig.3-10)
3. Adjustment 2 pole magnet, so that bright core position of dot

become center position of dot. (Fig.3-11)
