YH Adjustment (VR2 for Vertical dynamic
convergence)
1. Ap ply a crosshatch pattern.
2. Ad just contrast and brightness customer contro ls
to obtain a correct picture.
3. Wi th 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)
XV Adjustment(precise adjustment)
1. Ap ply a crosshatch pattern.
2. Ad just contrast and brightness customer contro ls
to obtain a correct picture.
3. Wi th a driver adjust the coil located in deflection
yoke board to obtain a proper convergence
horizontally.

Note: Apply a red pattern and confi rm 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. Pl ace strip between CRT and yoke, in quadrant
needing correction. Slowly move it around for
desired results.
2. Pr ess adhesive tightly to the CRT and secure
with tape.
DAF Adjustment
Preparation:
1. Ap ply a crosshatch pattern.
2. Se t user controls, bright to center and picture to
max.
3. Con nect a frequency counter to TPD10.
Procedure:
1. Con nec t chann el o ne of th e o scillosco p e with 10x1
probe to TPP33.
2. Con nect chan nel two of the o scilloscop e with 1 0x1
probe to CRT HEATER (L-Board).
3. Ad just R1581 so that frequency counter reads
15.7kHz±100Hz.
4. Ad ju st R157 7 so th at signa l o n TPP33 is o n phas e
with CRT HEATER (L-Board) pin. (see Fig. 16)
