Note : Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon paint on the CRT, after removing the anode.
•    REMOVAL OF ANODE-CAP
• HOW TO HANDLE THE ANODE-CAP
1 To prevent damaging the surface of the anode-cap do not use sharp materials.
2 Do not apply too great a pressure on the rubber, as this may cause damage to the 
anode connector.
3 A metal fitting called a shatter hook terminal is fitted inside the rubber cap.
Do not turn the rubber foot over excessively this may cause damage if the shatter 
hook sticks out.

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET
BOTTOM PLATES.(1) REMOVING THE PLATESIn the event of servicing being required to the solder side of the A Board printed
wiring board, the bottom plates fitted to the main chassis bracket require to be
removed.
This is performed by cutting the gates with a sharp wire cutter at the locations
shown and indicated by arrows.
Note :There are 2 plates fitted to the main bracket and secured by 4 gates.
Only remove the necessary plate to gain access to the printed wiring board.
(2) REFITTING THE PLATESBecause the plates differ in size it is important that the correct plates are refitted in
their original location.
Please note that the plates need to be rotated 180 degrees from the cut position to
to allow the tabs to be fitted in the catch positions. 
£
For safety reasons, on no account should the plates be
removed and not refitted after servicing.

• When complete readjustment is necessary or a new 
picture tube is installed, carry out the following 
adjustments.
• Unless there are specific instructions to the contrary,
carry out these adjustments with the rated power supply.
• Unless there are specific instructions to the contrary, set the 
controls and switches to the following settings :
Contrast ............... 80% [or remote control normal]
Brightness ............... 50%Carry out the following adjustments in this order :
3-1. Beam Landing
3-2. Convergence
3-3. Focus
3-4. White balance
Note :Test equipment required
1. Color bar/pattern generator.
2. Degausser.
3. Oscilloscope.
4. Digital multimeter.
5. DC Power supply.

Preparation:
1.In order to reduce the influence of geomagnetism on the set’s 
picture tube, face it in an easterly or westerly direction.
2. Switch on the TV set’s power and degauss with the
degausser.
3-1. BEAM LANDING
1. Input an all-white signal from the pattern generator.
Set the Contrast and Brightness to normal.
2. Set the pattern generator raster signal to all Red.
3. Move the deflection yolk forward and adjust with the purity
control so that the Red is at the centre and the Blue and Green
take up equally sized areas on each side of the screen. 
[See Fig.3-1 - 3-3].
4. Move the deflection yolk forward and adjust so that the entire
screen becomes Red. [See Fig.3-1].
5. Switch the raster signal to Blue, then to Green and verify the
purity condition.
6. When the position of the deflection yolk has been determined,
fasten the deflection yolk with the screws.
7. If the beam does not land correctly in all the corners, use 
magnets to correct it. [See Fig.3-4].

3-2. CONVERGENCE
Preparation:
• 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) Horizontal and vertical static convergence
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.

(2) Operation of the BMC (Hexapole) magnet.
• 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].
(3) Dynamic convergence adjustment.
Preparation:
• 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.3-3. Screen [G2], White balance
G2 Setting
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.
White balance adjustment
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.
3-4. FOCUS
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.
