TROUBLESHOOTING
A.
General:
A
general
guide
to
troubleshooting
of
a
flat
panel
display
system
it
worth
considering
the
system
as
separate
elements,
such
as:
Controller
(jumpers,
PC
settings)
Panel
(controller,
cabling,
connection,
panel,
PC
settings)
Backlight
(inverter,
cabling,
connection,
panel,
Pc
settings)
Cabling
Computer
system
(display
settings,
operating
system)
Through
checking
the
system
step
by
step
cross
with
instruction
manuals
and
a
process
of
elimination
to
isolate
the
problem
it
is
usually
possible
to
clearly
identify
the
problem
area.
B.
No
image:
If
the
panel
backlight
is
not
working
it
may
still
be
possible
to
see
just
some
image.
A
lack
of
image
is
most
likely
to
be
caused
by
incorrect
connection,
lack
of
power,
failure
to
provide
a
signal
or
incorrect
graphic
card
settings
.
C.
Image
position:
If
it
is
impossible
to
position
the
image
correctly,
the
image
adjustment
controls
will
not
move
the
image
far
enough,
then
test
using
another
graphics
card.
This
situation
can
occur
when
a
graphic
card
is
not
close
to
standard
timing
or
when
something
is
in
the
graphics
line
that
may
affect
the
signal
such
as
a
signal
splitter
(please
note
that
normally
a
signal
splitter
will
not
have
any
adverse
effect).
D.
Image
appearance:
A
faulty
panel
can
have
blank
lines,
failed
sections,
flickering
or
flashing
display.
Incorrect
graphic
card
refresh
rate,
resolution
or
interlaced
mode
will
probably
cause
the
image
to
be
the
wrong
size,
to
scroll
to,
flicker
badly
or
possibly
even
no
image.
Incorrect
jumper
settings
on
the
controller
may
cause
everything
from
incorrect
image
viewing
to
total
failure.
CAUTION:
Do
not
set
the
panel
power
input
incorrectly.
Sparkling
on
the
display:
faulty
panel
signal
cable.
E.
Backlight::
Items
to
check
include:
Power
input,
controls,
inverter
and
Tubes
generally
in
this
order.
If
half
the
screen
is
dimmer
than
the
other
half:
Check
cabling
for
the
inverter.
Also:
If
system
does
not
power
down
when
there
is
a
loss
of
signal.
