Analysis
*
This
color
television
set,
using
a
frequency
eGrineaear
system,
is
provided
with
a
1-chip
microcomputer
having
channel
display
(on
the
screen),
remote
control
and
On/
Off-timer
functions
(JVC
custom
high-integration
PLL
incorporated).
Interior
construction
in
includes
the
fol-
lowing
blocks:
(1)
remote
control,
(2)
control,
(3)
recep-
tion,
(4)
picture
amplification/sound
detection,
(5)
pic-
ture/chroma,
(6)
sound,
(7)
deflection,
(8)
high
voltage,
and
(9)
power
supply.
These
nine
blocks
are
described
as
follows.
,
1
Remote
Control
Remote
control
function
includes
power
supply
switching,
volume
adjustment,
and
channel
selection
conducted
by
utilizing
near-infrared
rays,
and
thus
eliminating
wiring.
The
transmitter,
using
an
IC1
(M50463P),
offers
26
functions
that
include
power
supply
switching
by
digital
code,
outputs
from
pin
,
and
drives
Q1
and
Q2,
Data
is
transmitted
from
the
near-infrared-ray,
light-emitting
diode
D1
(LN66-
S).
Transmitted
signals
are
received
by
the
photo
diode
D841
(PD49P!)
on
the
TV
set
and
input
in
pin
of
the
remote
control
amplifier
1C841
(uPC
1490HA).
Input
signals
are
amplified,
and
after
waveform
shap-
ing,
are
output
from
pin

Control
To
perform
overall
control
of
this
Model
the
control
unit
is
composed
of
a
4-bit
1-chip
microcomputer,
1C701
(MN15266JMC-1),
memory,
1C831
(MN12C
25),
reset
pulse
generator,
and
IC702
(MN1280-K).
When
the
set
is
turned
on,
initial
conditions
of
the
microcomputer
are
determined
by
the
output
pulse
of
1C702
pin
3),
and
the
program
incorporated
in
the
microcomputer
is
started.
This
microcomputer
has the
following
functions:

,
and
.
Data
for
selection
is
memorized
in
1C831
(MN12C25).
Selection
is
performed
by
a
key
scan
signal;
selected
data
is
output
from
pin
@)
and
input
into
the
microcom-
puter.
Real
time
The
microcomputer
has
a
clock
function
using
a
frequency
of
the
commercial
power
supply.
Input
taken
in
from
1C701
pin
is
processed
in
the
microcomputer,
Character

The
character
output
function
is
designed
to
dis-
play
characters
such
.as

are
sehtormed
by
the
microcomputer
controlling
tuner
TU701
and
VCO/band
selector
switch
1C801.
In
control,
a
re-
ceiving
frequency
is
determined
by
the
active
filter
of
1C801
(uPC1486C)
integrating
the
charge
pump
output
of
1C701
pin
9
and
adding
the
result
to
the
tuner.
Further,
1C701
pin
40
receives
pre-
scaler
output
from
the
tuner,
and
pin
69
out-
puts
a
prescaler

signal.
Stations
are
selected
by
inputting
