procedure.

FINAL CONVERGENCE PROCEDURE

NOTE
Vertical size and focus adjustments must be completed prior to performing the convergence
adjustment. Connect a dot pattern generator to the receiver. The brightness level should not be
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.

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
