— 11 — KV-27FS100L/29FS100L The following adjustments should be made when a complete realignment is required or a new picture tube is installed. These adjustments should be performed with rated power supply voltage unless otherwise noted. Set the controls as follows unless otherwise noted: VIDEO MODE: Standard PICTURE CONTROL: Normal BRIGHTNESS CONTROL: Normal SECTION 2: SET-UP ADJUSTMENTS Perform the adjustments in order as follows: 1. Beam Landing 2. Convergence 3. Focus 4. Screen (G2) 5. White Balance Note Test Equipment Required: 1. Color Bar Pattern Generator 2. Degausser 3. DC Power Supply 4. Digital Multimeter 2-1. BEAM LANDING Before beginning adjustment procedure: 1. Degauss the entire screen. 2. Feed in the white pattern signal. ADJUSTMENT PROCEDURE 1. Input a raster signal with the pattern generator. 2. Loosen the deflection yoke mounting screw, and set the purity control to the center as shown below: Purity Control 3. Turn the raster signal of the pattern generator to green. 4. Move the deflection yoke backward, and adjust with the purity control so that green is in the center and red and blue are even on both sides. ������� ����� 5. Move the deflection yoke forward, and adjust so that the entire screen becomes green. 6. Switch over the raster signal to red and blue and confirm the condition. 7. When the position of the deflection yoke is determined, tighten it with the deflection yoke mounting screw. 8. If landing at the corner is not right, adjust by using the disk magnets. a c b d ba c d Purity control corrects this area. Disk magnetsor rotatable diskmagnets correctthese areas (a-d). Deflection yoke positioningcorrects these areas.

VERTICAL STATIC CONVERGENCE 1. Adjust V. STAT magnet to converge red, green and blue dots in the center of the screen. 2. Tilt the V. STAT magnet and adjust static convergence to open or close the V. STAT magnet. When the V. STAT magnet is moved in the direction of arrow a and b, red, green, and blue dots move as shown below: B RGB RG RGB BGR 1 2 b bb bb b b aab aa aa 3 R G BB G R HORIZONTAL STATIC CONVERGENCE If the blue dot does not converge with the red and green dots, perform the following: 1.
