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.
