Check these items
• Make sure the power cord is properly connected.
• Make sure the u (POWER) switch is in the "ON" position.
• Try pressing any key on the computer keyboard.
• Make sure your computer is turned on.
• Make sure 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).
• Make sure none of the HD15 video input connector pins are bent or pushed in.
• Make sure the video board is completely seated in the proper bus slot.
• Make sure the video frequency range is within that specified for the monitor.
Horizontal: 30 – 107 kHz
Vertical: 48 – 160 Hz
Refer to your computer system's instruction manual to adjust the video frequency range.
• Run the SELF TEST function:
1. Turn off the monitor and disconnect the video cable from the computer.
2. Turn on the monitor and wait five seconds. The "NO INPUT SIGNAL" message
should appear with a color bar pattern. The message and pattern are
displayed for 60 seconds.
If the monitor displays White, Red, Green and Blue colors, the monitor is
functioning properly.
• Make sure none of the HD15 video input connector pins are bent or pushed in.
• Check your video board manual for the proper monitor setting.
• Check this manual and make sure the monitor supports the graphics mode and the
frequency at which you are trying to operate. 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 9).
If you place equipment which generates a magnetic field, such as a loudspeaker, near the
monitor, or you change the direction of the monitor, the color may not be uniform.
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.
Getting Started
Additional Information
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.
The message disappears after about 60 seconds.
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" (HD15) and "2" (5 BNC) are
displayed alternately.
