    connect an external monitor to the back connector of the laptop and verify if it does switch on when you put on the laptop. Do you hear any beeps or signals. look really hard into the monitor and check if there is a picture really faint. it happens when the screen gets bust.

How do i fix my LCD?


Hi,
I have got a hp pavilion dv5000, when I turn on it the screen goes blank.

Power led glows, I hear for a few time the fan, disk led flashes intermittently and also I feel that the DVD player tries to load.

If I try to click on caps lock or num lock, leds don't respond to commands. I tried the hard reset pressing the power button for 30 seconds with the battery and the power removed. Nothing to be done by connecting an external monitor....

What can I do ?qqb002.gif

Thank you

HP Pavilion dv1000 screen has gone extremely dim. changed the inverter and nothing. connected to an external monitor and nothing. what is wrong? HELP PLEASE!


Two things: video card issue or video card settings. Try to go to the power options configuration of your portable system. Adjust the brightness. If changes does not take effect on your portable's display as well as the external monitor, it is a video card issue. The last option of resolution is to re-install the video driver. Click the link below and choose the exact model of your computer. Try to download the video driver for your computer. Make sure that you have the correct driver for your operating system. If re-installing the video driver still fails, unfortunately you need to have your video card replaced. Usually the video card comes embedded on the motherboard. That means you have to have your whole board replaced.

HP Pavilion a1230n had bad power supply I changed it out for a better one of the same make and model. Now when it turns on I can hear the hard drive spinning and the fans running but it beeps every few...


If the beeping is coming from the power supply, that typically means that you are pulling too much wattage. I would recommend trying a higher wattage power supply. The video card is one of the lowest things on the computer's list of things to keep running at all costs, because even if your video card flickers off, you won't lose data. Before getting another new power supply though, I would ensure that your video cables are properly plugged into your video card and your monitor. To be sure that they are snug simply screw them in so that they don't wiggle at all when you pull on them.

All the lights turn on on the hp pavilion dv1000, but the screen remains black. Almost as if there was no power going to the screen. I have tried reseating the RAM and the HD. Problem still remains. ...


Hook a external monitor to the video output on the back of the laptop, if okay! there is a LCD problem with the laptop screen, causes! bad inverter board, or back light. If both show black! causes are Video Graphics Card that is part of the motherboard.

Blank screen HP DV1000 I can get video on an external monitor though


Your laptop may have video options:
* only internal LCD screen
* only external monitor (leaving your screen "dark")
* both screens.

Try toggling through the above 3 options.

After that, there's no part in the LCD screen that you can repair, by yourself.

So, if the computer is still under warranty, contact HP to exercise the warranty.

Otherwise, take the printer to a qualified technician, for proper trouble-shooting & repair.

Black screen when turn on the computer


The problem could be a loose video cable/connector.
Reseat the video cable or the connector that connects to the motherboard.
To check if the video card is faulty, connect an external monitor to the video port on the HP, power up the external monitor first, then bootup the laptop. The video will automatically switch to the external monitor and if you see a normal image then the video card is OK and the fault is the LCD screen/video connector.
If you see a faint image when you view the LCD screen at a sharp angle, then the fault could be the CCFL lamp or the inverter that supplies high voltage to the CCFL lamp.

HP Pavilion dv1000 Notebook PC display not coming on


Does the laptop power up even though you can't see an image on the screen?

Connect an external monitor to your laptop and powe it up, if you see the normal Windows images then the laptop is OK and the problem is the backlight.

If you see a very dim image or flicking image on the LCD screen it means you have a backlight problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
