SET-UP ADJUSTMENT
s The following adjustments should be made when a complete realignment is required or a new picture tube is installed. Perform the adjustments in order as follows : 1. Color Purity 2. Convergence 3. White Balance Note: The PURITY/CONVERGENCE MAGNET assembly and rubber wedges need mechanical positioning. Refer to figure 1. Mounting position of the purity magnet assembly should fit to same position as old one because slightly difference to the position depend on a kind of tube.
*
There are no adjustment of purity and convergence in some picture tube (Unified with purity magnet) 5. Remove the Rubber Wedges. 6. Rotate and spread the tabs of the purity magnet (See figure 2.) around the neck of the picture tube until the green belt is in the center of the screen. At the same time, enter the raster vertically. 7. Slowly move the yoke forward or backward until a uniform green screen is obtained. Tighten the clamp screw of the yoke temporarily. 8. Check the purity of the red and blue raster.
SPECIFIC INFORMATIONS GENERAL ADJUSTMENTS
COLOR PURITY ADJUSTMENT NOTE : Before attempting any purity adjustments, the receiver should be operated for at least fifteen minutes. 1. Demagnetize the picture tube and cabinet using a degaussing coil. 2. Set the brightness and contrast to maximum. 3. Use a green raster from among the built-in test signals. 4. Loosen the clamp screw holding the yoke and slide the yoke backward or forward to provide vertical green belt (zone) in the picture screen.
