Thank you for posting on the HP Support Community.

• Have you tried disconnecting and reconnecting the power cable?
• Are you getting any error message "No input signal"?
• Did you check with an alternate power source or wall outlet?

While you respond to that,

do the following items to prepare for troubleshooting:

• Turn off the computer.

• Disconnect all connected devices from the computer except the mouse, and keyboard. This includes removing thumb drives and camera-type memory cards.

• If the monitor has a detachable cable, obtain a second monitor cable for testing purposes.

Step 1: Checking the power

Disconnect the video cable from the monitor and make sure the monitor power cable is plugged into a power outlet.

With the monitor plugged in, press the power button on the monitor. There should be a power indicator light located on the monitor case. What happens to the light?

• If power light remains off when you press the power button, either the monitor is not receiving power or the monitor is defective. Check all of the following items before attempting to service or replace the monitor:

  • Make sure the power outlet has power and the power outlet matches the power rating for the monitor.

  • Connect the a different power outlet.

  • Try a different power cord.

• If the light comes on, the monitor has power. Continue to the next Step.

Step 2: Displaying a built-in on-screen message

Use the following steps to see if a built-in on-screen message displays.

1. Connect the video cable and turn on the computer.

2. Turn on the monitor and wait about ten seconds while the computer starts.

3. While the computer is starting, disconnect the video cable. What happens?

   • If a message appears on the monitor, the display panel is working and the problem is related to the video signal. For further troubleshooting steps, see Message about No Signal, Signal out of Range, Sleep, or Power Save.
