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.

2-2. CONVERGENCE
Before starting convergence adjustments:
1  Perform FOCUS, VLIN and VSIZE adjustments.
2.  Set BRIGHTNESS control to minimum.
3.  Feed in dot pattern.
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:
