Troubleshooting Tips

Monitor Has No Power
If the monitor's power indicator is off and no image appears on the display, perform the following checks:
• Ensure that the power cable is fully inserted in the monitor's power port and the electrical outlet.
• Test the electrical outlet by plugging in a working electrical device such as a lamp.
• Ensure that the power button has been depressed, and wait for the power indicator to light.
• Try another power cable on the monitor. Use the computer's power cable and turn on the monitor with the signal cable
disconnected. If the monitor is working correctly, a self-test pattern appears.
No Image Is Displayed on the Monitor
If the monitor power indicator is on but no image appears on the display, perform the following checks:
• Ensure that the video connector is seated properly. Tighten the connector screws securely with your fingers.
• Ensure that the computer is on.
• Increase brightness and contrast controls.
• Turn off the monitor and unplug the signal cable. Check the cable connector for bent or broken pins.
• With the signal cable still disconnected, turn on the monitor. If the monitor is working correctly, a self-test pattern
appears.
• Perform a monitor reset or recall.
