Chapter 6: Troubleshooting Monitor Your server is running but there is no picture ■ Adjust the brightness and contrast controls to the center position. ■ Make sure that the monitor is plugged in and turned on. If the monitor is turned on, the power LED should be lit. ■ Check the cable for bent or damaged pins. ■ Connect your monitor to another computer, or connect a monitor that you know works to your server. The color is not uniform Make sure that the monitor warms up for at least 30 minutes before making a final judgment about color uniformity. Make sure that: ■ The monitor is not positioned too close to another monitor, electric fan, or fluorescent light. ■ You demagnetize the screen using the monitor's degauss feature. For more information on degauss, see the monitor's documentation. A horizontal line or wire is visible across the monitor screen The monitor may use thin damper wires, located approximately 1/3 of the way from the upper and lower screen edges, to stabilize the internal aperture grille. These wires are most obvious when the monitor displays a white background. The aperture grille allows more light to pass through the screen for brighter colors and greater luminescence. The damper wire is a critical part of the overall monitor design and does not negatively affect the monitor's function. Power You press the power button, but the server does not turn on ■ Make sure that both AC power cords are connected to your server and a wall outlet. ■ If the power LED is green, the server is turned on, but you may not be seeing an image on the monitor.
