• Check that the power cord is properly connected.
• Check that the u (power) switch is in the “on” position.
• The screen is blank when the monitor is in power saving mode. Try pressing any key on the
computer keyboard.
• Check that your computer power switch is in the “on” position.
• Check that the input select setting is correct.
• Check that the video signal cable is properly connected and all plugs are firmly seated in
their sockets.
• Check that the 5 BNCs are connected in the correct order (from left to right: Red–Green–
Blue–HD–VD) (page 6).
• Ensure that no pins are bent or pushed in the HD15 video input connector.
• Check that the video board is completely seated in the proper bus slot.
• Check that the video frequency range is within that specified for the monitor.
Horizontal: 30 – 96 kHz, Vertical: 48 – 160 Hz
Refer to your computer’s instruction manual to adjust the video frequency range.
• If you are using a video signal cable adapter, check that it is correct.
• See “Self-diagnosis Function” (page 22).
• Check that the Macintosh adapter and the video signal cable are properly connected (page
6).
• If you replaced an old monitor with this monitor, reconnect the old monitor and do the
following. Install the Windows Monitor Information Disk (page 7) and select
“CPD-520GS” from among the Sony monitors in the Windows 95/98 monitor selection
screen. If you choose to select “Plug and Play,” connect the monitor to the computer with
the HD15 video signal. You cannot use the five BNC connectors.
• Check your graphics board manual for the proper monitor setting.
• Check this manual and confirm that the graphics mode and the frequency you are trying to
operate at is supported. Even if the frequency is within the proper range, some video
boards may have a sync pulse that is too narrow for the monitor to sync correctly.
