Troubleshooting

This section may help you isolate a problem and as a result,
eliminate the need to contact technical support, allowing
continued productivity.
No picture
/ If neither the u (power) indicator nor the
POWER SAVING indicator is lit
— Check that the power cord is properly
connected.
— Check that the power switch is in the "ON"
position.
/ If the POWER SAVING indicator is lit
— Check that your computer power switch is
in the "ON" position.
— The monitor will recover when you press
any key on the keyboard of the computer.
— Check that the video cable is properly
connected.
— Ensure that no pins are bent or pushed in
the HD15 connector of the cable.
— Check that the video card is seated
completely in a proper bus slot.
— Check that the video sync signal is within
that specified for the monitor.
— If using a Mac system, check that a proper
HD15-D15 adaptor is provided to work
correctly with your Macintosh.
/ If you do the above procedures and the
monitor does not recover.
— Unplug the video cable (HD15) then press
and hold the ¨ + button for 2 seconds to
display the color bars. Then, turn the
monitor off and on by pressing the
u power switch.
If the monitor does not recover, the
monitor is out of order.
/ If the u (power) and/or the POWER SAVING
indicator is flashing
— Turn the monitor off and on. If the
indicator is not flashing, the monitor is in
the normal condition. If the indicator is still
flashing, there is a potential monitor
failure.
/ If your computer is a Macintosh system
— Check that micro switches are properly set
on the Macintosh adapter for your system.
(See the adapter manual.)
Picture is scrambled
/ Check your graphics board manual for the
proper monitor setting on your Multiscan
20sfII.
/ Check this manual and confirm that the
graphic mode and the frequency at which you
are trying to operate is supported. Even
within the proper range some video boards
may have a sync pulse that is too narrow for
the monitor to sync correctly.
Color is not uniform
/ Trip the power switch once to activate the
Auto-degauss cycle*.

White does not look white
/ Adjust the "COLOR TEMPERATURE" on the
OSD. (page 7)
/ If your computer is a Macintosh system, check
that micro switches are properly set on the
Macintosh adapter for your system. (See the
adapter manual.)
Screen image is not centered or sized properly
/ Adjust the "CENTER", "SIZE", or
"GEOMETRY" on the OSD (page 5, 6).
/ Some video modes do not fill the screen to the
edge of the monitor. There is no single answer
to solve the problem. There is a tendency to
have this problem on higher refresh timings
and Macintosh video timings.
Edges of the image are curved
/ Adjust pincushion using the "GEOMETRY"
OSD. (page 6)
White lines show red or blue shades at edges
/ Adjust the "CONVERGENCE" on the OSD.
(page 7)
Picture is fuzzy
/ Adjust the "CONTRAST" and
"BRIGHTNESS" on the OSD (page 5). We
have come across several brands of SVGA
boards that have an excessive video output
level which creates a fuzzy picture at max
contrast.
/ Trip the power switch once to activate the
Auto-degauss cycle*.
/ If red or blue shades are found at the edge of
images, adjust the "CONVERGENCE" on the
OSD. (page 7)
Picture bounces or has wavy oscillations
/ Isolate and eliminate any potential sources of
electric or magnetic fields. Common causes for
this symptom are electric fans, fluorescent
lighting, laser printers, and so on.
/ If you have another monitor close to this
monitor, increase the distance between them
to reduce the interference.
/ Try plugging the monitor into a different AC
outlet, preferably on a different circuit.
/ Try the monitor on a completely different
computer in a differnt room.
Picture appears to be ghosting
/ Eliminate the use of video cable extension
cables and/or video switch boxes if this
symptom occurs. Excessive cable length or
weak connections can produce this symptom.
Two fine horizontal lines (wires) are visible
/ These wires stabilize the vertically striped
Aperture Grille. This Aperture Grille allows
more light to pass through to the screen giving
the Trinitron CRT more color and brightness.
