Video problems
The system is running but there is no display.
The text on the display is dim or difficult to read.
Probable Cause Solution
The monitor is not turned on. Make sure the monitor is plugged in and turned
on. If power is applied to the monitor, the green
power LED should illuminate.
The monitor’s data cable is
not connected. Make sure the monitor’s data cable is
connected to the video controller on the back
of the system.
The connector or cable is
damaged. Check the connector and cable for bent or
damaged pins.
The monitor is defective. Connect a working monitor to the computer.
The monitor’s brightness and
contrast controls are turned
down. Adjust the brightness and contrast knobs to the
center position.
The video card is not seated
correctly. Open the system and reseat the video card.
The video card is not
compatible with the system. Make sure the card is compatible with your
system. Try a different video card.
Important Some systems do not have a video adapter card because
the video controller is built into the system board, so there
may not be a video adapter to remove and replace.
Probable Cause Solution
The monitor’s brightness and
contrast controls are turned
down. Adjust the brightness and contrast knobs until
the text becomes clear.
Sunlight is glaring off the
display. Position the monitor away from the sun or
window.
The CRT may be old. Replace the monitor.
