Troubleshooting Tips
The picture seems to be constantly moving.
1. The monitor has lost its vertical sync. Adjust the monitor’s
vertical sync.
2. Move away any objects, such as another monitor or fan, that
may be creating a magnetic field around the display.
The screen seems to be constantly wavering.
If the monitor is close to another monitor, the adjacent monitor
may need to be turned off. Fluorescent lights adjacent to the
monitor may also cause screen wavering.
The hard disk drive failed.
Make sure the correct drive type has been entered in the BIOS.
The disk drive takes excessively long formatting period.
If your hard drive takes an excessively long period of time to
format, it is likely a cable connection problem. However, if your
hard drive has a large capacity, it will take a longer time to
format.
The serial device is not working.
1. Make sure that the serial device’s power (if there is one) is
turned on and that the device is on-line.
2. Verify that the device is properly plugged into the serial port
on the rear of the system.
3. Verify that the attached serial device works by attaching it to a
serial port that is working and configured correctly. If the
serial device does not work, either the cable or the serial
device has a problem. If the serial device works, the problem
may be due to the onboard I/O or the address setting.
4. Make sure the COM settings and I/O address are configured
correctly.
