Troubleshooting
Solution
Make sure the monitor is plugged in and turned
on. If power is applied to the monitor, the green
power LED should illuminate.
Make sure the monitor data cable is connected
to the video controller on the back of the
system.
Check the connector and cable for bent or
damaged pins.
Connect a working monitor to the computer.
Adjust the brightness and contrast knobs to the
center position.
Open the system and reseat the video card.
Make sure the card is compatible with your
system. Try a different PCI video card.
Some systems may have a built-in video adapter, so there
may not be a video adapter to remove and replace.
Solution
Adjust the brightness and contrast knobs until
the text becomes clear.
Position the monitor away from the sun or
window.
