IMPORTANT SERVICE NOTES
Maintenance
and
repairof
this receiver
should bedoneby qualified
service personnel
only.
SERVICING OF HIGH VOLTAGE
SYSTEM AND PICTURE
TUBE
When servicing
the
high voltage
system, remove static
charge from it by
connecting a 10k ohm
Resistor in series with an
insulated wire
(such
as a test
probe) between picture tube
tag and
2nd anode
lead. (AC
line
cord should be disconnected
from AC outlet.)
1.
Picture tube in
this receiver
employs integral implosion
protection.
2.
Replace
with tube of the
same
type number for continued safety.
3. Do not
lift
picture tube by the neck.
4.
Handle the picture tube only when wearing shatter-proof
goggles and
after
discharging
the
high voltage completely.
X-RAY
This receiver is designed so that any
X-ray radiation is kept to
an
absolute
minimum. Since
certain
malfunctions or servicing
may
pro-
duce potentially hazardous
rediation with prolonged exposure at
close
range,
the
following
precautions should be
observed:
1:
When repairing the circuit, be
sure
not to
increase
the
high voltage to
more the
28kV, (at beam 1 .l mA), for
the
set.
2.
To
keep
the
set in a
normal
operation, be sure
to make it function
on 25.0kV + 1.5 kV
(at
beam
1.2
mA) in
the
case of
the
set.
The
set
has been
factory-adjusted to the above-mentioned
high voltage.
. .
If
there is a possibility
that
the
high voltage
fluctuates as a
result
of the
repairs, never
forget to check
for such high voltage after
the work.
3. Do not substitute a picture tube
with
unauthorized types
and/or
brands
which may
cause excess
X-ray radiation.
BEFORE
RETURNING THE RECEIVER
Before returning the
receiver to
the
user, perform
the
following
safety
checks.
1.
Inspect
all lead dress to
make certain
that leads are
not pinched or
that
hardware is not lodged between the
chassis and
other metal
parts in
the
receiver.
2. Inspect
all
protective
devices such as non-metallic
control knobs,
insulating fishpapers, cabinet
backs,
adjustment
and compartment
covers or shields,
isolation resistor-capacity networks, mechinical
insulators
etc.

When one of “1” to “10” keys is pushed, the data of the corresponding position is read out of the
memory so that the desired station is tuned in. The currently selected station is stored as lastly selected position in the memory.
When one of “1 fl to “10” keys is pushed, the corresponding position is displayed on LED. But the data in the memory remains as it is.
Not operative.
When FT(+) or
FT(-)
key is pushed, APT is turned
off and the unit performs a sweeping of tuning voltage. And when the key is touched off, the data
of tuning voltage is written in the memory.
Within 2 seconds after “10” key has been pushed,
when one of “I” to “6” keys is pushed, one of
“11“
to “16” positions is displayed and tuned in;
when one of “7” to “IO” keys is, however,
pushed, one of
“7”

and tuned in.

6. Tuning operation When one of “1” to “IO” keys is pushed in the normal
mode, the corresponding data is read out of the EA ROM so that the band output and tuning voltage are set up to allow the unit to tune in the desired station. Then
the currently tuned in station is stored as a lastly
selected position in the specified address of EA ROM. During the tuning operation, AFT output and MUTE output are caused in the following timing.

activates the vertical drive circuit and vertical

(2
)
When the vertical drive circuit and vertical output
circuit are in action, it is only in the
flyback
period that the booster (pump up) circuit is allowed to operate to provide the voltage about twice
Vcc.
(3
I) The design that the supply voltage is boosted only
in the
flyback
period results in remarkably reduced
power consumption.
(4) In the c
onventional
SRPP output circuit,
Vcc
must
be supplied until the
flyback
pulse voltage reaches
its highest value.
In this circuit, however, it is sufficient to use about half of Vcc for the circuitry operation.

IC701
RH-iX0689CEZZ
(POWER REGULATOR)
1. Oscillation principle (1) When the power switch is turned on, a current
IsI
is
applied to the base of TR5.
(2) Then, a current lc=hfe.ls, is applied to the collector
of TR5.
(3) The current lc available at the collector of TR5
causes a voltage (feedback voltage of the same polarity) at
T701.
(4) As the feedback voltage is given, a current
IF
available at pin @ of
l701
is allowed to run through 0705 and R711 and enter the base of TR5. When the feedback voltage increases to more than the speci­fied level, TR5 starts its oscillation.
(5) As the voltage at the collector of TR5 increases to
its saturation point, a reverse bias is applied to its base to interrupt the oscillation.
(6) When the oscillation of TR5 is stopped, the energy
stored in
T701
is discharged through the secondary
winding N4.
(7) Then there is caused a voltage (of the reverse
polarity) at Nl and N2 to turn on TR5 again. Thereafter, the process is repeated for TR5 to perform the oscillation continuously.
2. Operational principle of error amplifier (1) The voltage which is induced at N3 winding is DC
rectified to produce a control voltage (between pins
@ and
0).
The control voltage available at N3 is highly correla­tive with the output voltage of N4 because both N3 and N4 are electrically coupled with each other.
(2) Variation of the control voltage is detected by TRl
and
ZDl.
(3) As the det
ec e voltage increases, it is amplified by
t d
TR2 and TR3 so that the current at the base of TR5
is bypassed.
(4) Then the current at the collector of TR5 is limited to
the smallest.
(5) Accordingly, the pulse width is controlled to decide
the duration where TR5 is kept turned on.
3. Over-current protector circuit (1) An over-current 12 is applied to TR4. With TR4
turned on, the current at the base of TR5 is so
reduced that TR5 will eventually stop the oscillation.
(2) With the
over-current applied to TR5, there is
caused a
voltage
between
pins@and@of T701 and
this
voltage
is
supplied
via 0705 and
R711 to the
base
of
TR5, so
that Vin
DC is allowed to
run in C708 and R708
to
enter the
base
of
TR5.
In
the actual
circuitry,
however,
this
current
Vin
DC can’t
reach
the
base
of
TR5 because
that C708 has
already
been charged up.

When replacing or handling the IC, be sure to put on your wrist a metal ring (earth ring) that is connected to ground.
+
Avoid touching the IC directly by hand as much as
possible. For the soldering iron and other jigs in use, be sure to connect them to ground so that their potential is the same as that of the PWB and/or IC. The PWB cannot be connected to ground in some condition although you attempt to attach the IC to that PWB. In this case, be sure to keep the PWB at the same potential as ground by touching it by your
hand on which a metal ring is put. When handling the IC, it is recommended for you to wear such clothes as not causing static electricity; the ones of wool, silk or synthetic fiber should be
avoided. This is important in particular when hand-
ling the IC in a dry environment.

Note:
The probe of oscilloscope in
use
must be of a low
capacitance (2 to 3

ARE IMPORTANT
MAINTAINING THE SAFETY OF THE SET. BE SURE TO RE­PLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAIN­ING THE SAFETY AND PERFORMANCE OF THE SET.
CAUTION:
This circuit diagram is original one, therefore there may be a slight difference from yours. All the voltages in each point are measured with digital multi meter. All these figures represent the voltage levels measured upon reception of colour signals.
Waveform Measurement Conditions
1.
Upon receiving
EBU
colour bar signal of 70 dB in field intensity.
2. m indicates wave form check points (See chart, waveforms and measured from point indicated to chassis ground).
