Check these items
• Check that the power cord is properly connected.
• Check that the u power switch is in the "on" position.
• Check that your computer power switch is in the "on" position.
• The monitor will recover when you press any key on the keyboard of the computer.
• The input select switch setting is incorrect.
• Check that the video signal cable is properly connected and all plugs are firmly seated
in their socket.
• Check that the 5 BNC's are connected in the correct order (from the power cord side:
Red–Green–Blue–HD–VD).
• Ensure that no pins are bent or pushed in the HD15 video input connector.
• Check that the video board is seated completely in the proper bus slot.
• Check that the video frequency range is within that specified for the monitor.
(Horizontal: 30 – 96 kHz, Vertical: 50 – 160 Hz)
• Turn the monitor off and on. If the indicator is off, the monitor is in the normal
condition. If the indicator is still flashing, there is a potential monitor failure.
• Unplug the video input 1 and 2 connectors and wait for 5 seconds. Then press and
hold the > + button for 2 seconds to display the color bars. If the color bars appear,
the monitor may be in normal condition. Turn the monitor off and on to return to the
normal operation mode. If the color bars do not appear, there is a potential monitor
failure.
• Check your graphic board manual for proper monitor setting.
• Check this manual and confirm that the graphic mode and the frequency at which
you are trying to operate is supported (page 6). Even 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 15).
If you place equipment which generates a magnetic field such as a loudspeaker, or
you change the direction of the monitor, color may lose uniformity.
This function is to demagnetize 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 (page 10).
• If the control lock function is set to on, set it to off on the OPTION OSD (page 15).
You will be able to adjust the monitor.
• Adjust color (pages 11, 14).
• Check that the 5 BNC's are connected in the correct order (from the power cord side:
Red–Green–Blue–HD–VD).
• Adjust the centering or size (pages 9, 13).
• Some video modes do not fill the screen to the edge of the monitor. There is no single
answer to solve the problem. This problem tends to occur on higher refresh timings.
• Adjust the geometry items such as pincushion and keystone distortion (pages 10, 13).
