Trouble symptoms and remedies

If a problem occurs as a result of a connected computer or other equipment, refer to the connected computer/equipment’s instruction manual.

Use the self-diagnosis function (page 24) if the following recommendations do not resolve the problem.

Symptom Check these items

No picture

If the 1 (power) indicator is not lit,

or if the 1 (power) indicator will not

light up when the 1 (power) switch

is pressed,

• Check that the power cord is properly connected.

If the 1 (power) indicator is green, • Use the self-diagnosis function (page 24).

If “CABLE DISCONNECTED”

appears on the screen,

• 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.

If “NO INPUT SIGNAL” appears on

the screen, or the 1 (power)

indicator is amber,

• 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.

If “OUT OF RANGE” appears on

the screen (page 21),

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 using Windows, • 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.”

If using a Macintosh system, • When connecting a Macintosh computer, use an adapter (not supplied) if necessary.

Connect the adapter to the computer before connecting the video signal cable.

Picture flickers, bounces,

oscillates, or is scrambled.

• 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).
