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 ﬁ eld around the display.

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

tor.

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 ﬂ oppy 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-protect-

ed.

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 ad-

equate storage space.
