•REMOVAL OF ANODE-CAP
Note : Short circuit the anode of t he picture tube and the anode cap to the metal chassis, CRT shield or carbon paint on th e CRT, after removing the anode.
•HOW TO HANDLE THE ANODE-CAP
1To prevent damaging the surface of the a node -cap do not use sharp materials.
2Do not apply too great a pressure on the rubber, as this may cause damage to the
anode connector.
3A metal fitting ca lled a shatter hook terminal is fitted inside the rub ber 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 being required to the solder side of the A Board printed
wiring board, the bottom plates fitted to the main chassis bracket r equ ire 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.
15
(2)REFITTING THE PLATES
Because the plates differ in size it is important th at the corr ect pla tes are ref it ted 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 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 r as ter signal to Red.
3.Move the deflection yoke 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 yoke forw ard 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
condition.
6.When the pos ition of the deflection yoke has been determ ined,
fasten the deflection yoke with the screws.
7.If the beam does not land cor r ectly in all the corners, use a
magnet 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 required
1.Color bar/pattern generator.
2.Degausser.
3.Oscilloscope.
4.Digital multimeter.
5.DC Power supply.

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
•Tilt the V.STAT magnet and adjust the static convergence
by opening or clo s ing the V.STAT m a gnet.
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.
1.[Moving horizontally], adjust the H.STAT control so that the
Red, Green and Blue points are o n t op 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 o n t op 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 belo w.
[In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other].

Tilt Direction
•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).
(2)Dynamic convergence adjustment.
Preparation:
•Before starting this adjustment, adjust the horizontal and
vertical static convergence.
1.Remove the deflection yoke spacer.
2.Tilt the deflection yoke as indicated in the figure below and
optimize the convergence.
3.Re-install the deflection yoke spacer.
Note :This adjustment will affect the geometry of the
display, therefore adjust to obtain the optimum
setting.

Note :
•All capacitors are in µF unless otherwise noted.
•pF : µµF 50WV or less are not indicated except for
electrolytic types.
•Indication of resistance, which does not have one for
rating electrical power, is as follows.
Pitch : 5mm
Electrical power rating : 1/4W
•Chip resistors are 1/10W
•All resistors are in ohms.
k = 1000 ohms, M = 1000,000 ohms
•: nonflammable resistor.
•: fusible resistor.
•: internal component.
•: panel designation or adjustment for repair.
•All variable and adjustable resistors have
characteristic curve B, unless otherwise noted.
•All voltages are in Volts.
•Readings are taken with a 10Mohm digital mutimeter.
•Readings are taken with a color bar input signal.
•Voltage variations may be noted due to normal production
tolerences.
