Check these items
• 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.
• Ensure that no pins are bent or pushed in the 13W3 video input cable.
• 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.
• See "Self-diagnosis Function" (page 20).
• 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.
• Degauss the monitor (page 14).
If you place equipment which generates a magnetic field, such as a loudspeaker, near the
monitor, or you change the direction of the monitor, color may lose uniformity.
The degauss function demagnetizes the metal frame of the CRT to obtain a neutral field for
uniform color reproduction. If a second degauss cycle is needed, allow a minimum interval
of 20 minutes for the best result.
• Adjust the landing (pages 12 – 13).
1 The input signal condition
"OUT OF SCAN RANGE" indicates that the input signal
is not supported by the monitor's specifications.
"NO INPUT SIGNAL" indicates that no signal is input, or
the input signal from the selected input connector is not
received.
2 The selected input connector
Indicates which input connector is receiving the wrong
signal. If there is something wrong with the signal from
both input connectors, "1" (13W3) and "2" (HD15) are
displayed alternately.
To solve these problems, see "Troubleshooting" below.
