TAPE RUNNING SYSTEM When cleaning the tape transport system, use the gauze moistened with isopropyl alcohol. 3. CYLINDER Wrap a piece of chamois around your finger. Dip it in isopropyl alcohol. Hold it to the cylinder head softly. Turn the cylinder head counterclockwise to clean it (in the direction of the arrow). (Refer to the figure below.) NOTE Do not exert force against the cylinder head. Do not move the chamois upward or downward on the head. Use the chamois one by one.

ELECTRICAL ADJUSTMENTS
1. BEFORE MAKING ELECTRICAL ADJUSTMENTS
Read and perform these adjustments when repairing the circuits or replacing electrical parts or PCB assemblies. CAUTION · Use an isolation transformer when performing any service on this chassis. · Before removing the anode cap, discharge electricity because it contains high voltage. · When removing a PCB or related component, after unfastening or changing a wire, be sure to put the wire back in its original position. · When you exchange IC and Transistor for a heat sink, apply the silicon grease (YG6260M) on the contact section of the heat sink. Before applying new silicon grease, remove all the old silicon grease. (Old grease may cause damages to the IC and Transistor). Prepare the following measurement tools for electrical adjustments. 1. Oscilloscope 2. Digital Voltmeter 3. Multi-sound Generator 4. Pattern Generator On-Screen Display Adjustment 1. Unplug the AC plug for more than 5 seconds to set the clock to the non-setting state. Then, set the volume level to minimum. 2. Press the VOL.

NOTE 1. Turn the unit on and let it warm up for at least 30 minutes before performing the following adjustments. 2. Place the CRT surface facing east or west to reduce the terrestrial magnetism. 3. Turn ON the unit and demagnetize with a Degauss Coil. 3-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT) 1. Tighten the screw for the magnet. Refer to the adjusted CRT for the position. (Refer to Fig. 3-1) If the deflection yoke and magnet are in one body, untighten the screw for the body. 2. Receive the green raster pattern from the color bar generator. 3. Slide the deflection yoke until it touches the funnel side of the CRT. 4. Adjust center of screen to green, with red and blue on the sides, using the pair of purity magnets. 5. Switch the color bar generator from the green raster pattern to the crosshatch pattern. 6. Combine red and blue of the 3 color crosshatch pattern on the center of the screen by adjusting the pair of 4 pole magnets. 7. Combine red/blue (magenta) and green by adjusting the pair of 6 pole magnets. 8. Adjust the crosshatch pattern to change to white by repeating steps 6 and 7. 3-2: PURITY NOTE Adjust after performing adjustments in section 3-1. 1. Receive the green raster pattern from color bar generator. 2. Adjust the pair of purity magnets to center the color on the screen. Adjust the pair of purity magnets so the color at the ends are equally wide. 3. Move the deflection yoke backward (to neck side) slowly, and stop it at the position when the whole screen is green. 4. Confirm red and blue color. 5. Adjust the slant of the deflection yoke while watching the screen, then tighten the fixing screw. DEFLECTION YOKE DEFLECTION YOKE SCREW MAGNET SCREW 3-3: STATIC CONVERGENCE NOTE Adjust after performing adjustments in section 3-2. 1. Receive the crosshatch pattern from the color bar generator. 2. Combine red and blue of the 3 color crosshatch pattern on the center of the screen by adjusting the pair of 4 pole magnets. 3. Combine red/blue (magenta) and green by adjusting the pair of 6 pole magnets. 3-4: DYNAMIC CONVERGENCE NOTE Adjust after performing adjustments in section 3-3. 1. Adjust the differences around the screen by moving the deflection yoke upward/downward and right/left. (Refer to Fig. 3-2-a) 2. Insert three wedges between the deflection yoke and CRT funnel to fix the deflection yoke. (Refer to Fig. 3-2-b) RGB RGB
