• 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.
• Check that the Input 1-2 switch settin is correct (page 5).
• 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 video input connector.
• Check that the graphic board is completely seated in the proper bus slot.
• The computer is in power saving mode. Try pressing any key on the computer
keyboard, or moving the mouse.
• Check that your computer power switch is in the “on” position.
• Check that the graphic board is completely seated in the proper bus slot.
• Check that the video frequency range is within that specified for the monitor.
(Horizontal: 30 – 107kHz, Vertical: 48 – 120 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 the correct one.
• 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 graphic boards may have a sync pulse that is too narrow for the monitor to sync
correctly.
• Degauss the monitor (page 11).
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.
• If the control lock function is set to ON, set it to OFF using the OPTION OSD
(page 13).
• Adjust the color temperature (page 9).
