STATIC CONVERGENCE ADJUSTMENT
(Same as AV-24LS and AV-25LX.) 1. Input a crosshatch signal. 2. Using 4-pole convergence magnets, overlap the red and blue lines in the centre of the screen (Fig. 4) and turn them to magenta (red/blue). 3. Using 6-pole convergence magnets, overlap the magenta(red/blue) and green lines in the centre of the screen and turn them to white.

4. Repeat 2 and 3 above, and make best convergence.

DYNAMIC CONVERGENCE ADJUSTMENT
(Procedure is changed from AV-25LS and AV-25LX.) 1. Move the deflection yoke up and down to adjust the pin cushion distortion in the screen top and bottom. (Fig. 5) 2. Move the deflection yoke left to right to overlap the lines in the periphery, and match the Yv. (Fig. 6) 3. Using the VR on the deflection yoke, match the YH (CROSS). (Fig. 7 and 9) 4. Repeat the steps 1 and 3 and obtain an optimum convergence. 5. Differential coil ADJUSTMENT. In case where the horizontal lines of red and blue around the centre of both sides of the picture as shown in Fig. 8, adjust the XV difference by using the differential coil on the top of the deflection yoke (Fig. 9) so as to minimize the XV difference.

� After adjustment, fix the wedge at the original position.
Fasten the retainer screw of the deflection yoke. Fix the PC magnet with glue.
