Check these items
• Check that the power cord is properly connected.
• Use the self-diagnosis function (page 24).
• Check that the video signal cable is properly connected and all plugs are firmly seated in
their sockets (page 7).
• Check that the video input connector's pins are not bent or pushed in.
• Check that the input select setting is correct (page 11).
• A non-supplied video signal cable is connected. If you connect a non-supplied video
signal cable, "CABLE DISCONNECTED" may appear on the screen. This is not a
malfunction.
• Check that the video signal cable is properly connected and all plugs are firmly seated in
their sockets (page 7).
• Check that the video input connector's pins are not bent or pushed in.
• Check that the input select setting is correct (page 11).
xProblem caused by a connected computer or other equipment, and not
caused by the monitor
• The computer is in the power saving mode. Try pressing any key on the keyboard or
moving the mouse.
• Check that your graphics board is installed properly.
• Check that the computer's power is on.
xProblem caused by a connected computer or other equipment, and not
caused by the monitor
• Check that the video frequency range is within that specified for the monitor. If you
replaced an old monitor with this monitor, reconnect the old monitor and adjust the
computer's graphics board within the following ranges:
Horizontal frequency: 28–80 kHz (Analog RGB), 28–64 kHz (Digital RGB)
Vertical frequency: 48–75 Hz (Analog RGB), 60 Hz (Digital RGB)
Resolution: 1280 × 1024 or less
• If you replaced an old monitor with this monitor, reconnect the old monitor and do the
following. Select "SONY" from the "Manufacturers" list and select "SDM-HX73 or
SDM-HX93" from the "Models" list in the Windows device selection screen. If "SDM-
HX73 or SDM-HX93" does not appear in the "Models" list, try "Plug & Play."
• When connecting a Macintosh computer, use an adapter (not supplied) if necessary.
Connect the adapter to the computer before connecting the video signal cable.
• Adjust the pitch and phase (analog RGB signal only) (page 16).
• Isolate and eliminate any potential sources of electric or magnetic fields such as other
monitors, laser printers, electric fans, fluorescent lighting, or televisions.
• Move the monitor away from power lines or place a magnetic shield near the monitor.
• Try plugging the monitor into a different AC outlet, preferably on a different circuit.
• Change the orientation of the monitor.
xProblem caused by a connected computer or other equipment, and not
caused by the monitor
• Check your graphics board manual for the proper monitor setting.
• Confirm that the graphics mode (VESA, Macintosh 19'' Color, etc.) and the frequency of
the input signal are supported by this monitor. Even if the frequency is within the proper
range, some graphics boards may have a sync pulse that is too narrow for the monitor to
sync with correctly.
• This monitor does not process interlace signals. Set for progressive signals.
• Adjust the computer's refresh rate (vertical frequency) to obtain the best possible picture
(60 Hz is recommended).
