Question about HP Pavilion dv9000z Notebook

HP Dv9800 Blank Display

My almost new (just 2 months old) HP Pavillion DV 9800 has developed an issue where display is completely blank after starting the computer. It flashes for a second and then goes off completely. There are no tones or beeps. I have taken out the battery and drained the power and then tried to turn it on but the issue still persists. A few days ago, there were few issues with Graphic card Nivdia but computer worked after restarting the computer.

Since the computer was purchased from eBay, HP says there is no warranty. I have tried using it with external display and it works fine.

Anyone have any idea?

    Please explain the solution fully rather than shooting randomly.

  • bloach Oct 06, 2008

    There is no issue with wiring.

  • bloach Oct 06, 2008

    I followed your solution. If I keep the escape button or F1 and F2 buttons pressed, nothing happens and I see the Windows boot sound after a while. If I start it and keep escape pressing up and down, there are strong beeps after a few seconds.

  • bloach Oct 06, 2008

    HP won't provide warranty as I mentioned in the problem. Please read the problem before you answer it.

  • bloach Oct 06, 2008

    I just tried to set up the external display and now external display is also not working.

  • bloach Oct 07, 2008

    I am returning the laptop to the seller for a refund. However, now external display doesn't work so I will need to take out the hard disk and copy the data to my computer. I have a hard disk enclosure so all I need to find out is how to take out the hard disk from my laptop. Can anyone please give me step by step directions for removing hard disk and copying data and I will select that solution.

    Thanks

It clear you got a faulty LCD display which is a common problem with laptops since the screen is always flipped up and down.

need to have it replaced at your own expense since manufacturers doesn't like ebay for some reason

about the external video output, let the computer to boot normally and use the Fn + Function key (check your keyboard) to activate

Hi,
as you have said that there is a display on external monitor , this shows that your system is working fine, the problem is in the display panel, this is due to the cable that gives display to your panel, get it checked by a technician, you have to replace this cable.

Well it is pretty clear that the problem is the display itself not the graphics card. A bad graphics card would give you no display on external monitor as well. As Ekse suggested it is probably just a bad connector. It can also be the LCD inverter board that is present inside the LCD screen of the monitor behind the panel. You can usually find an Inverter board for a pretty low price on e-bay. I bought one for 35$ the other day for fixing a client's Lappy. Worth a go if you are skilled enough in electronics. Otherwise the best thing would be to seek proffessional assistance.

Good Luck!

Hey it sounds as the external is working fine that the internal lcd connectors may be loose or lcd board / inverter is faulty

Posted on Oct 06, 2008

  • Ekse Oct 06, 2008

    you will have to open up the laptop, check or reconnect the lcd cables / connecotrs (1-3)

    Check the cables, this can be easyer to fix than you think. A cable could be loose or broken.

  • First, reformat the hard
    drive. Under Windows, you can format by going to My Computer,
    right-click the icon for the hard drive, and then select Format. When
    the format completes, you will have erased all files from the drive.

  • Since your computer now has an empty hard drive,
    you'll need to re-install the operating system with the original
    CDROMs. It's still possible, but pretty unlikely, that some shreds of
    your old files might still be visible. But finding them requires some
    pretty advanced sleuthing tools and a lot of determination.
    If that solution doesn't satisfy you, there are two other options you can try:



  • Hard Disk cleaning tools such as Disk Wipe, Drive
    Scrubber or R-Wipe & Clean claim to remove every last shred of your
    personal files. You can also search the Web for "disk wipe" or "file
    shredder" to find similar software options.

  • Remove the hard drive and hit it with a sledge hammer


  • mohammed marika thambi
    mohammed marika thambi Oct 07, 2008

    You will have to go through the 'Remove Disk' wizard,
    where WHS will try to move the existing files if there is space
    available. You could also switch off duplication prior to removal, to
    free up some extra space.
    When you re-add the drive, you could then re-enable Duplication, to allow the extra space to be utilised.

      To jump start it ---- press Esc button as soon as you turn it on, hold it until something happens can take 20 sec or more and may take more than 1 attempt.
      sometimes if Esc fails then restart and press F1 or F2 buttons then hold it. When it starts you follow the instructions it gives.

      I think its a problem with one of the following Ram, Rom, systemboard or Bios

      hope it helps, tell me if it does.......

    • mastermind10 Oct 06, 2008

      or try this if it still does not solve your problem

      remove the battery and take out the jumper, move it from slot 1+2 to 2+3 and back to 1+2. Put the battery back in, and the it Booted.mostly it starts working.

    • mastermind10 Oct 06, 2008

      I think you might have a failed screen inverter (FL inverter); this problem is very common with laptops. The inverter board acts as a power supply for the LCD screen backlight bulb, it converts low voltage DC power into high voltage AC. On most laptops the inverter board is located inside the display assembly below the LCD screen and you can get access to it if you remove the screen bezel (LCD mask). When the screen inverter goes bad the backlight will not turn on anymore or it turns on for a short time and then goes off, but you still can see a faint image on the screen and the external monitor works just fine. First of all I would make sure it’s not just a loose connection and reseat connectors on the inverter (it looks like you already done this part). Next, I would try replacing the inverter board. It might fix your problem with the backlight. It’s possible that you have a faulty cable, bad motherboard or even bad LCD screen, but I would try replacing the screen inverter first.

    • mastermind10 Oct 06, 2008

      Here is a simple diagram that will help you to understand how a notebook display assembly works and how an image appears on the screen. I’m not an artist and I tried my best drawing this diagram, so if you cannot see a laptop in this picture,

      for diagrams click this link below

      http://www.laptoprepair101.com/laptop/20...



      A generic display assembly includes a very few parts and knowing them will help you to understand witch part can cause a problem if you laptop video not working properly.



      Video cable. A video signal from the motherboard goes to the LCD screen through the video cable. The video cable connects to the motherboard (or video card) through the connector 1. The video cable connects to the LCD screen through the connector 2. The video cable (in most cases) is also responsible for supplying a necessary voltage for the FL inverter board. The video cable connects to the FL inverter board at the point 3.



      FL inverter board. This board is responsible for converting low voltage DC power (point 3) to high voltage AC (point 4), necessary to light up the backlight bulb. If the FL inverter board is bad, the LCD screen (backlight bulb) will not light up when you turn on the laptop, but you still should be able to see a very dim image on the screen.

      Looking for a new screen, video cable or inverter board? Find it here.



      CCFL (backlight bulb). When the backlight bulb lights up, you can see an images on the LCD screen. In most cases the backlight bulb is a part of the LCD screen and if it’s bad, the entire screen has to be replaced. By the way, some specialized repair shops can replace the backlight bulb itself.



      Lid close switch. The lid close switch is a small button that locates close to the display hinges. On some newer models there is no button, because the switch is magnetic. You can set up your laptop to go to a hibernation mode or to a standby mode when the LCD is closed. It’s done through power management software. These modes are triggered when the display is closed and the lid close switch is pressed down. If the LCD screen on your laptop will not light up when you open the display assembly, check the lid close switch is stuck inside (it might happen because the switch is dirty).

    • mastermind10 Oct 06, 2008

      the beep ensures that there might be problem in the RAM in *********** board please remove and reinsert the RAM . try cleaning the golden lines on the RAM with a rubber (which we use in schools for rubbing pencil marks ).



      and also check the link above which i had sended in my coment before that has a diagram of how the screen works that will give you more perfect idea.

    Hi All,


    This happens because of static energy storing in the motherboard components.

    We can try power drain to resolve this issue.


    Try doing power drain by taking out the battery & keep holding down the power button for complete one minute to drain out the power from the computer components. Restart the computer after putting the battery in.
    Try restarting the computer only with the AC power, without the battery & vice-versa.

    That should resolve the issue, if the issue persists, then you have to contact service center.


    Hope that information helped you!!
