My HP a6500f is acting up. An image will display during start up and then goes blank. Power light is on for the monitor, but nothing but a blank screen. The monitor works. How can I fix this problem?

Hi
You have a leaking capacitor. The monitor is fixable. Check my website @ www.micromendllc.com

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a few seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Look to see if you do have 12~18vdc feeding the backlight inverter board (located on the left side of the monitor), it can also have blown fuses on the inverter board. Post back what you see inside so we can guide you further, this is really old monitor, 2002.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

It's possible the video card is burnt out from over heating.If it is you need a new motherboard.

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

power shortage maybe...try to plug your monitor on the other power supply,,be sure that your monitor is compatible on the voltage it required..

It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)

hi try this ,,,

1. Ensure the video cable is connected (and connected to the correct video port).
2. Turn off the monitor using the monitor's power button and then restart the monitor.
3. Cycle the power on the monitor as follows:
4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
5. Unplug the power cord.
6. Wait 5 seconds.
7. Plug in the power cord.
8. Press the power button on the monitor to turn on the monitor. One of two things happens:
   1. The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
   2. The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
   3. Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
      • If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
      • If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
      hope it will work for u .. little_angel
      

I am not familiar with your particular model, but I do know what the problem is.
The inverter that runs the lights behind the screen is faulty and needs to be repaired. The lights shine from the top and bottom and reflect outwards through the panel so you can see what is on the screen. If you start the computer up, then shine a bright light into the panel you will see an image on the screen, but very feintly.
This can be cheap, it can also be expensive depending on where you go to get it repaired. Call aorund to a few TV shops in your area to get a rough idea on prices.

Hope that helps =)
