Solved!

(Monitor Problem) Screen lights up for a split second then blue on/off light blinks

HP Recommended
HP w1907
Microsoft Windows 8.1 (64-bit)

This monitor is old. About 10 years old. I have it hooked up to my Toshiba laptop, same age. I was doing my normal thing until suddenly the screen went black. I thought it was the power but the monitor's on/off light was on, and blinking. I check the VGA cable and it was fine. I tried to shut off computer power and turn on again, but the screen stayed off. It will not show anything but it's still on. I try everything and fail. I see that every time it turns on, I can see a dim white triangle that usually shows VGA and DVI input and resolution for a split second. I really need help as this is the oldest thing that isn't me. I can't use my laptop since the screen is broken from transport. I need help.

@meem36314,

 

Welcome to the HP Support Community!

 

Have you checked the monitor with a different computer or your laptop with a TV or monitor?

 

Meanwhile, 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?
  4. If a message is displayed, the display panel is working and the problem is related to the video signal.
  5. If the display remains blank, turn off the computer and continue troubleshooting.
  6. 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 how it goes and you have a great day!
