• HOW TO HANDLE THE ANODE-CAP
1 To prevent damaging the surface of th e anode-cap do not use sharp materials.
2 Do not apply too great a pressure on the rubbe r, as this may cau s e da mage 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.
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 b eing required to the sold er 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 PLATES
Because the plates differ in size it is important that the correct plates a re ref itted in
their original location.
Please note that the plates need to be rotated 180 degrees from the cut position to
allow the tabs to be fitted in the catch positions.

SET-UP ADJUSTMENTS
• 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%
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 be en determined,
fasten the deflection yolk with the screws.
7. If the beam does not lan d correctly in all 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
3-4. Focus
3-3. White balance
Note : Test equipment requ ired
1. Color bar/pattern generator.
2. Degausser.
3. Oscilloscope.
4. Digital multimeter.
5. DC Power supply.
