SET-UP ADJUSTMENTS

3-1. SCREEN VOL T A GE ADJUSTMENT

(ROUGH ALIGNMENT)

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. Loose the lens screw.

2. Set in service mode.

3. Place the caps on the red and blue lens so that only the green color is shown.

4. Press the Commander button and select OSD (CHSW) to display the test signal (crosshatch) on the screen.

5. Rotate the green lens and align with the optimal focus point from the test signal.

6. Rotate the green VR on the FOCUS Pack and align to obtain the optimal focus point.

7. Perform the same alignment for red and blue lenses and electric focus.

8. Fix lens screw.

1. Set to receive the Monoscope signal.

2. Set in service mode.

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

4. 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.

5. After aligning the deflection yoke, fasten it securely to the funnel-shaped portion (neck) of the CRT.

6. The tilt of the deflection yoke for red and Blue is aligned the same as was done for green.

3-3. SCREEN (G2) ADJUSTMENT

1. Connect JIG (A) to 200 V and GND.

2. Select VIDEO mode without signals.

3. Connect JIG to the TP701(KR), TP731(KG) or TP761(KB) of CR board, CG board and CB board.

4. Adjust R, G and B screen voltage to until retrace line disappears with screen VR on the focusblock.

2. Set to receive the Dot signal.

3. Place the caps on the red and blue lens so that only the green color is shown.

4. Turn the green VR on the focus b lock to the right and set to overfocus to enlarge the spot.

5. Now align the 2-Pole Magnet so that the enlarged spot is in the center of the Just Focus spot.

6. Align the green focus VR and set for just (precise) focus.

7. Perform the same alignment for red and blue.

3-8-1. Green and Red Lens Focus Adjustment

1) Input a monoscope signal.

2) Place a lens cover over Red and Blue lenses and project only Green.

3) Rotate the Green lens and ajust to obtain the best lens focus.

4) Fix lens screw.

5) Repeat above process for Red.

3-8-2. Green and Red Electrical Focus Adjustment

1) Input a monoscope signal.

2) Project only Green.

3) Rotate the green focus volume on the focus pack and adjust to obtain an optimal electrical focus in the top right corner, taking care of center focus is not NG. obtain a compromise between center and corner focus.

4) Repeat above process for Red.
