•

Before starting this adjustment, adjust the focus, horizontal
size and vertical size.

•

Minimize the Brightness setting.

•

Input a dot pattern from the pattern generator.

1.

[Moving horizontally], adjust the H.STAT control so that the
Red, Green and Blue points are on top of each other at the
centre of the screen.

2.

[Moving vertically], adjust the V.STAT magnet so that the 
Red, Green and Blue points are on top of each other at the 
centre of the screen.

3.

If the H.STAT variable resistor is unable to bring the Red,
Green and Blue points together at the centre of the screen,
adjust the horizontal convergence with the H.STAT variable 
resistor and the V.STAT magnet in the manner indicated below.
[In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other].

•

Tilt the V.STAT magnet and adjust the static convergence
by opening or closing the V.STAT magnet.

4.

If the V.STAT magnet is moved in the direction of the    a
and   b   arrows, the Red, Green and Blue points move as
indicated below.

•

The respective dot position resulting from moving each 
magnet interact, so be sure to perform adjustment whilst
tracking.
Use the H.STAT VR to adjust the Red, Green and Blue dots
so that they coincide at the centre of the screen
[by moving the dots in the horizontal direction].

•

Before starting this adjustment, adjust the horizontal and 
vertical static convergence.

1.

Slightly loosen the deflection yolk screws.

2.

Remove the deflection yolk spacer.

3.

Move the deflection yolk as indicated in the figure below and
optimize the convergence.

4.

Tighten the deflection yolk screws.

5.

Re-install the deflection yolk spacer.

•

If you are unable to adjust the corner convergence properly, 
this can be corrected by the use of permalloy assemblies.

1.

Input a dot signal from the pattern generator.

2.

Set the Picture, Brightness and Colour to minimum.

3.

Apply 170Vdc from an external power supply to the 
R, G and B cathodes of the CRT.

4.

Whilst watching the picture, adjust the G2 control [RV701 
SCREEN] located on the C Board to the point just before the 
flyback return lines disappear.

1.

Input a ‘PAL’ all-white signal from the pattern generator.

2.

Enter into the Service Mode.

3.

Enter into the ‘Picture’ service menu.

4.

Select the ‘Green drive’ and adjust so that the White Balance
becomes optimum.

5.

Select the ‘Blue drive’ and adjust so that the White Balance
becomes optimum.

6.

Set the Picture to MIN.

7.

Set the ‘R-cut-off’ to 07.

8.

Adjust the ‘G-cut-off’, and the ‘B-cut-off’ so that the White 
Balance becomes optimum.

10.

Press the

button to return to TV operation.

1.

Input a Phillips colour pattern

2.

Set the picture settings to normal.

3.

Adjust the focus control located on the Flyback transformer to 
bring the centre of the screen into focus.

Note :Bring only the centre area of the screen into focus, switch to an

all-white pattern and confirm that the magenta ring is hardly 
noticed. To obtain optimum focus balance the focus setting 
between optimum screen centre focus and a reduced magenta 
ring level.
