Very good service Within one day i received a pdf of the users manual and electric circuits so I was able to measure the different voltages in the printed circuit and find out the fault Payment was also reliable and easy.Without the manual i could not have repaired.So thanks to "Search for a manual"

STATIC CONVERGENCE ADJUSTMENT [AV-25L91-BK]
1. Input a crosshatch signal. 2. Using 4-pole convergence magnets, overlap the red and blue lines in the centre of the screen (Fig. 7) 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.

3. Using the YH VR on the deflection yoke, match the YH (CROSS). (Fig. 7 and 12) 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. 11, adjust the XV difference by using the differential coil on the top of the deflection yoke (Fig. 12) so as to minimize the XV difference.
