Leakage
Current
Check
Plug
the
AC
line
cord
directly
int
o
the
AC
outlet
(do
not
use
line
isolation
transform
ers
during
this
check).
Using
a
“Leakage

Test
er”,
m
easure
the
leakage
current
fro
m
each
exposed
metal
part
of
the
cabinet,
particularly
an
y
exposed
m
etal
part
having
a
return
path
t
o
the
chassis,
to
a
known
good
earth
ground
(water
pipe,
etc.).
Any
leakag
e
current
must
not
exceed
0.5mA
AC
(r.m.s.).
However,
in
tropical
area,
this
must
not
exceed
0.2mA
AC
(r.m.s.).
Alternate
Check
Method
Plug
the
AC
line
cord
directly
into
the
AC
outlet
(
do
not
use
a
line
isolation
transformer
during
this
check.).
Use
an
A
C
voltmeter
having
1000
ohm
s
per
volt
or
more
sensitivity
i
n
the
following
manner.
Connect
a
1500
10W
resisto
r
paralleled
by
a
0.15µF
AC-type
capacit
or
between
a
n
exposed
m
etal
part
and
a
known
good
earth
ground
(wate
r
pipe,
etc.).
Measure
the
AC
voltage
across
the
resistor
wit
h
the
AC
voltmeter.
Move
the
resistor
connection
to
eac
h
exposed
metal
part,
particularly
any
exposed
metal
par
t
having
a
return
path
to
the
chassis,
and
m
easure
the
A
C
voltage
across
the
resistor.
Now,
reverse
the
plug
in
the
A
C
outlet
and
repeat
each
m
easurem
ent.
Any
voltage
measur
ed
must
not
exceed
0.75V
AC
(r.m.s.).
This
corresponds
to
0.5mA
AC
(r.m
.s.).
However,
in
tropical
area,
this
must
not
exceed
0.3V
AC
(r.m.s.).
This
corresponds
to
0.2m

NOTE:
MTK1389D
is
a
type
of
LSIC
for
DVD
decode
.MTK1389D
IC
consists
of
RF,SERVO,DSP,DECODE,VIDEO
DAC
and
AUDIO
DAC.
1.
Under
normal
power
supply
conditions,
the
maintenance
plan
for
MT1389D
mono-chip
is:
first
the
rese
t
circuit
resets
the
MT1389D,
after
the
crystal
oscillator
circuit
gave
the
clock
signal
to
MT1389D,
MT1389D
wil
l
start
the
initialization
check
for
Flash
E
2
PROM
SDRAM,
after
everything
is
checked
to
be
normal,
it
will
star
t
initialization
check
for
built-in
Audio
DAC,
servo
and
motor
Driver
IC
.
2.
If
the
all
the
a.m.
parts
are
good,
then
MT1389D
will
send
signal
to
motor
Driver
to
drive
the
serv
o
system
pick
up
then
to
generate
DVD
light
for
collection,
tracing
the
main
shaft
to
check
if
there
is
any
disc
,
and confirm
if
it
is
CD
format
or
DVD
format
disc.
If
the
disc
is
in
DVD
format,
the
system
will
read
the
dat
a
from
the disc
directly;
if
it
is
in
CD
format
built-in
servo
will
drive
the
CD
laser
to
send
out
CD
light
and
read
th
e
data,
the data
then
will
be
amplified
through
built-in
RF
amplifier
and
sent
to
MT1389D
decode
part
for
dat
a
processing, released
by
MPEG
and
resolved
into
video
data
and
audio
data,
then
they
will
be
returned
t
o
analog
signals through
built-in
VIDEO
DAC
AUDIO
DAC.
Decoder
section
3.
There
is
power
supply,
clock
and
reset,
but
the
system
does
not
work.
1
Check
if
all
the
address
wires
required
for
FLASH
are
exist,
and
if
they
are
in
normal
status
,
especially
check
if
the
A0~A15
of
FLASH
have
normal
signals,
if
there
arent,
then
inspect
MT1389D
to
see
i
f
there
is
faulty
soldering.
If
there
are
normal
signals
at
A0~A15,
check
if
the
address
data
signal
of
MT1389
D
and
SDRAM
is
normal.
If
it
is
normal,
then
check
the
signal
at
A16~A19
of
MT1389D;
if
there
are
also
signals
,
then
check
the
video
output
wires
and
AV
filter
circuit;
if
there
is
no
signal,
then
check
the
corresponding
pins
of
MT1389D
to
see
if
there
is
any
short
circuit,
break
or
faulty
soldering.
4.
System
in
normal
operation,
but
the
audio
has
no
sound.
1
Because
the
AUDIO
DAC
is
built
in
MTK1389D
IC.you
need
to
check
the
lower
passing
amplifyin
g
circuit
and
the
MUTE
circuit
at
the
back
of
the
LPF
circuit.
Also
check
if
there
is
any
power
supply
to
the
LP
F
circuit.
2
Check
if
the
power
supply
voltage
required
for
playing
is
at
normal
level.

After
the
LOGO
of
the
machine
shows
normally,
there
is
no
OSD
display.
This
problem
mainly
is
caused
by
the
abnormality
built-in
RF
and
servo,
possible
problems
may
be:
1
Built
in
RF
and
its
surrounding
circuits
have
problems.
2)
Servo
part
of
MT1389D
has
problems.
6.

is
normal
while
there
is
no
action
of
servo
par
t
feeding
motor
does
not
work,
main
shaft
does
no
turn,
possible
fault
status
are:
1)
The
corresponding
signals
giving
by
MT1389D
to
DMSO
FMSO
are
missing,
the
reason
may
be
the
problem
of
MT1389D
or
the
communication
between
MT1389D
and
motor
Driver
IC
SA5668.
2)
Not
output
from
Motor
Driver,
the
reason
may
be
the
problem
on
motor
Driver
or
its
corresponding
circuit.
7.
Servo
part
in
good
status,
while
there
is
no
pick
up
action
no

1
No
light,
check
the
power
suppl
y
power
supply
for
pick
up
,
or
the
light
producing
driving
circuit
to
see
if
they
are
in
normal
status.
2
No
focus,
check
MT1389D
to
see
if
there
is
signal
output
from
FOSO
TRSO.
Secondly,
check
motor
driver
to
see
if
there
is
F+
F-
T+
T-signal
output.
Thirdly,
check
the
external
corresponding
circuit
of
the
motor
driver
to
see
if
there
is
any
problem.
8.
All
the
servo
part
has
action,
while
it
cannot
read
out
the
disc
1
Check
MT1389D
if
there
is
RF
net
picture
output,
if
there
isn’t,
then
it
must
be
the
problem
o
f
MT1389D
and
external
surrounding
circuits,
it
there
is
output,
then
it
might
the
problem
of
MT1389
D
and
its
surrounding
circuits.
2
There
is
RF
signal
but
not
in
normal
status
then
check
MT1389D
and
surrounding
circuits.
3
Everything
is
normal,
but
the
disc
cannot
be
read
out,
check
MT1389D
and
its
surrounding
circuit
