If you do need assistance, please call the phone number on the warranty card, the phone number on the Information section or contact your dealer. Symptom No images on the screen. I cannot turn on the monitor. Check List Solutions Is the power cord connected properly? Check the power cord connection and supply. Can you see "No Connection, Check Signal Cable" on the screen? (Connected using the D-sub cable) Check to see if the computer is connected properly. (Connected using the DVI cable) If you still see an (error) message on the screen when the monitor is connected properly, check to see if the monitor status is set to analogue. Press Source button to have the monitor double-check the input signal source. If the power is on, reboot the computer to see the initial screen (the login screen), which can be seen. If the initial screen (the login screen) appears, boot the computer in the applicable mode (the safe mode for Windows ME/2000/XP) and then change the frequency of the video card. (Refer to the Preset Display Modes) Can you see "Video mode not supported" on the screen? Note: If the initial screen (the login screen) does not appear, contact a service center or your dealer. You can see this message when the signal from the video card exceeds the maximum resolution and frequency that the monitor can properly handle. Adjust the maximum resolution and frequency that the monitor can properly handle. There is no image on the screen. Is the power indicator on the monitor blinking at 1 second intervals? The monitor is in PowerSaver mode. Press a key on the keyboard or move the mouse to activate the monitor and restore the image on the screen. Connected using the DVI cable? You may get a blank screen if you boot the system before you connect the DVI cable, or disconnect and then reconnect the DVI cable while the system is running as certain types of graphic cards do not send out video signals. Connect the DVI cable and then reboot the system.
