higher than necessary to obtain a clear pattern. Converge the red and the blue dots at the center of the screen by rotating the R&B pole static convergence magnets. Align the converged red/blue dots with the green dots at the center of the screen by rotating the R &B&G pole static convergence magnets. Melt wax with soldering iron to reseal the magnets. Slightly tilt vertically and horizontally (do not rotate) the deflection yoke to obtain a good overall convergence. If convergence is not reached at the edges, insert permalloy in the DY corners to achieve proper convergence. Recheck for purity and readjust if necessary. After vertical adjustment of the yoke, insert wedge at 11 o�clock position, then make the horizontal tilt adjustment. Secure the deflection yoke by inserting four side wedges. Apply adhesive between tab (thin portion) of wedge and CRT and place tape over the tab to secure to the CRT.
14.1. DYNAMIC CONVERGENCE ADJUSTMENT
Use this for a precisely overall convergence adjust at the edges. DY(YHC, YV, XV) ADJUSTMENT YV ADJUSTMENT / (VR1 FOR HORIZONTAL DYNAMIC CONVERGENCE)
1. Apply a crosshatch pattern. 2. Adjust contrast and brightness customer controls to obtain a correct picture. 3. With a driver adjust VR1 (located in deflection yoke board to obtain a proper corvergence at top and bottom of the screen
