YH Adjustment (VR2 for Vertical dynamic convergence)

1.Apply a crosshatch pattern.

2.Adjust contrast and brightness customer controls to obtain a correct picture.

3.With a driver Adjust VR2 (located in deflection yoke board Fig. 19) to obtain a proper corvergence at left and right side of the screen. (See Fig. 14)

Note: Apply a red pattern and confirm purity, if purity is poor, repeat purity adjustments.

Permalloy Convergence Corrector Strip (Part No. 0FMK014ZZ)

This strip is used in some sets to match the yoke and CRT for optimum convergence. If the yoke or CRT is replaced, the strip may not be required.

First converge the set without the strip and observe the corners.

If correction is needed:

1.Place strip between CRT and yoke, in quadrant needing correction. Slowly move it around for desired results.

2.Press adhesive tightly to the CRT and secure with tape.

DAF Adjustment

Preparation:

1.Apply a crosshatch pattern.

2.Set user controls, bright to center and picture to max.

3.Connect a frequency counter to TPD10.

Procedure:

1.Connect channel one of the oscilloscope with 10x1 probe to TPP33.

2.Connect channel two of the oscilloscope with 10x1 probe to CRT HEATER (L-Board).

3.Adjust R1581 so that frequency counter reads 15.7kHz±100Hz.
