Troubleshooting

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.

3.Make sure your video card’s output frequencies are supported by this monitor.

The screen seems to be constantly wavering.

1.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.

Power Supply

When the computer is turned on, nothing happens.

1.Check that one end of the AC power cord is plugged into a live outlet and the other end properly plugged into the back of the system.

2.Make sure that the voltage selection switch on the back panel is set for the correct type of voltage you are using.

3.The power cord may have a “short” or “open”. Inspect the cord and install a new one if necessary.

Floppy Drive

The computer cannot access the floppy drive.

1.The floppy diskette may not be formatted. Format the diskette and try again.

2.The diskette may be write-protected. Use a diskette that is not write-protected.

3.You may be writing to the wrong drive. Check the path statement to make sure you are writing to the targeted drive.

4.There is not enough space left on the diskette. Use another diskette with adequate storage space.
