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)

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.

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
100x1 probe to TPP33 (pin-1 T1551).
2. Connect channel two of the oscilloscope with 10x1
probe to CRT HEATER (L-Board).
3. Adjust "HDAFP" so both waves are in the same
position.
4. Adjust "HDAFW" so TPP33 is 1.5
