1. Receive the Monoscope signal.
2. Set 50% BRIGHTNESS and minimum PICTURE.
3. Turn the red VR on the focus pack all the way to the left and

then gradually turn it to the right until the point where you can
see the retrace line.

4. Next gradually turn it to the left to the position where the

retrace line disappears.

1. Turn on the power of the set.
2. Select VIDEO1 and make no signal input.
3. Supply DC (177.5 

± 0.5V) from external power supply to KR

(Fig.3-2).

3. Turn red of G2 VR clockwise, then retrace line appear.
4. Turn G2 VR counterclockwise and set retrace line just

disappear (Fig.3-3).

5. Add DC voltage DC (174 

± 0.5V) to KR.

6. Confirm if retrace can be seen.
7. Adjust green and blue at the same method.

1. Connect VIDEO-1 terminal.
2. Receive video dot hatch pattern.
3. Use lens-cover to red and blue.

4. Adjust electric focus (roughly).
5. Rotate the green lens and adjust to obtain the best lens focus.
6. Rotate the green focus volume on the focus pack and adjust to

obtain best electrical focus.

7. If focus is not good, repeat 4 process.
8. Repeat above process for red and blue lenses and electric fo-

cus.

9. Fix lens screw.

1. Receive the Monoscope signal.
2. Place the caps on the red and blue lens so that only the green

color.

3. Loosen the deflection yoke setscrew and align the tilt of the

Deflection yoke so that the bars at the center of the
monoscope pattern are horizontal.

4. After aligning the deflection yoke, fasten it securely to the

funnel-shaped portion of the CRT.

5. The tilt of the deflection yoke for red and blue is aligned the

same as was done for green.

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).
