Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

As I understand the monitor blacks out after it's turned on, 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you check the power, are the connections firm on both ends?

Did you reset the monitor?

While you respond to that, here are a few steps I recommend:

Before you begin

Do the following things to prepare for troubleshooting:

• Turn off the computer.

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

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

• Disconnect the display power cable, wait about 30 seconds, reconnect the cable and then turn on the display. This resets the electronics on the display. Make sure the display has power and the power light comes on when the power button is pressed. If the light on the display remains off, the display is not receiving power from either the wall outlet or the power adapter.

Check the power

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

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

• If the power light comes on, the display has power, skip to Listen to the computer and look at the lights.

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

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

  • Connect the display to a different power outlet.

  • Try a different power cord.

  If the light comes on, the display has power. Continue to the next section.

Reset the display

At first setup, or under certain signal conditions, the display might not be able to switch to a new display resolution. Do not shut down or restart the computer. Instead, perform the following steps:

You should see the image from the computer on the screen. If not, continue with the troubleshooting.

On-screen message shows on the display

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

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

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

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

   • If a message is displayed, the display panel is working and the problem is related to the video signal. For further troubleshooting steps, see HP support document, Flat Panel Monitor Displays Message about No Signal, Signal out of Range, Sleep, or Power Save.

   • If the display remains blank, turn off the computer and continue troubleshooting.

   • Some displays do not have on-screen messages but instead use the lights to indicate no signal. When you disconnect the cable, instead of an on-screen message, the light turns amber, indicating that the display lost signal and is working properly, but is out of range, or not receiving the signal.

Let me know if those steps worked for you,

If they did, that's awesome!

Thanks for your quick response to my question. Sorry I did not reply sooner but I was waiting to borrow another video cable to try. I tried your suggestions and a new cable. I also connected the defective monitor to another computer and same problem . I borrowed another monitor abd connected it to first computer, works fine but I prefer the 4:3 ratio of my old monitor and was hoping to repair it. I hooked it back up to first computer with new cable and now it stays black all the time. Power light is on. If I touch sleep button on keyboard monitor goes to sleep but no on screen messages. When pressing sleep button again it wakes up and there is a quick flash of an image, a fraction of a second. on screen. Power light stays on, (blue).I suppose a component may have failed such as a capacitor orchip. I would appreciate any other suggestions. Thanks again.
