INSTALLATION AND SERVICE ADJUSTMENTS
GENERAL INFORMATIONS
All adjustments are thoroughly checked and corrected
when the receiver leaves the factory. Therefore the
receiver should operate normally and produce proper
colour and B/W pictures upon installation. However,
several
minor
adjustments
may
be
required
depending
on the particular location
in which
the
receiver is operated.
This receiver is shipped
completely
in cardboard
carton. Carefully draw out the receiver from the carton
and remove all packing materials. Plug the power cord
into a convenient 220 volts 50 Hz AC two pin power
outlet. Turn the receiver ON. Check and adjust all the
customer
controls
such
as
BRIGHTNESS,
CONTRAST
and COLOUR
Controls to obtain natural
colour or B/W picture.
AUTOMATIC DEGAUSSING
A degaussing coil is mounted around the picture tube
so that external degaussing after moving the receiver
is normally unnecessary,
providing the receiver
is
properly degaussed upon installation. The degaussing
coil operates for about 1 second after the power to the
receiver is switched ON. If the set is moved or faced
in a different direction, the power switch
must
be
switched
off at least 30 minutes
in order that the
automatic
degaussing
circuit
operates
properly.
Should the chassis or parts of the cabinet become
magnetized
to cause
poor colour
purity, use
an
external degaussing coil. Slowly move the degaussing
coil around the faceplate of the picture tube, the sides
and front of the receiver and slowly withdraw the coil
to a distance of about 2 m before disconnecting it
from AC source.
HIGH VOLTAGE CHECK
CAUTION:
There
is no HIGH
VOLTAGE
ADJUST-
oe on this chassis.
. Connect an accurate
high voltage meter to the
second anode of the picture tube.
2. Turn on the receiver. Set the BRIGHTNESS
and
CONTRAST
Controls
to minimum
(zero beam
current).
3. High voltage will be measured below 32.0 kV.
4. Rotate the BRIGHTNESS Control to both extremes
to be sure the high voltage does not exceed the
limit of 32.0 kV under any conditions.
FOCUS ADJUSTMENT
Adjust FOCUS
Control on FLYBACK TRANS. (1461)
for well defined scanning lines in the centre area on
the screen.,
