Troubleshooting
PROBLEM: There is no picture on the monitor.
If there's no picture on the monitor, please perform the following steps:
1.Make sure the power indicator on the monitor is ON, all connections are secured, and the system is running on the correct timing. Refer to Chapter 3 for information on timing.
2.Turn off the monitor and then turn it back on again. If there is still no picture, press the Adjustment Control button several times.
3.If step 2 doesn't work, connect your PC system to another external CRT. If your PC system Functions properly with a CRT monitor but it does not function with the monitor, the output timing of the VGA card may be out of the LCD's synchronous range. Please change to an alternative mode listed in the Standard Timing Table or replace the VGA card, and then repeat steps 1 and 2.
PROBLEM: There is no picture on monitor.
If you have chosen an output timing that is outside of the monitor's synchronous range (Horizontal: 30~ 80KHz and Vertical: 56 ~ 75 Hz), the OSD will display an "Out of Range" message. Choose a mode that is supported by your monitor.
Also, if the signal cable is not connected to monitor at all or properly, the monitor screen will display a message "No Input Signal".
