• HOW TO HANDLE THE ANODE-CAP
1 To preve nt damaging the surface of th e a node-cap do not use sharp materia ls.
2 Do not apply too great a pressure on the rubber, as this may cau s e damage to the
anode connector.
3 A metal fitting called a shatter hook terminal is fit ted inside the rubbe r ca p.
Do not turn the rubber foot over excessively this may cause damage if the shatter

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET
BOTTOM PLATES.
For safety reasons, on no account should the plates be
£
removed and not refitted after servicing.
(1) REMOVING THE PLATES
In the event of servicing being required to the solder side of t he 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 plat e to gain access to the printed wiring board.

SET-UP ADJUSTMENTS
• When com pl ete readjustment is necessary or a new
picture tube is installed, carry out the following
adjustments.
• Unless there are sp eci fic instructions to the contrary,
carry out these adjustments with the rated power supply.
• Unless there are sp eci fic instructions to the contrary, set the
controls and switches to the following settings :
Contrast ............... 80% [or remote control normal]
Brightness ............... 50%
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 si gnal 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 i n al l the corners, use
magnets to correct it. [See Fig.3-4].
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 requ ired
1. Color bar/pattern generator.
2. Degausser.
3. Oscilloscope.
4. Digital multimeter.
5. DC Power supply.

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.STA T magnet in the manner indicated below.
[In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other].

so that they coincide at the centre of the screen
[by moving the dots in the horizontal direction].
