You'll need to remove the battery in order to access a series of screws that loosed the keypad and the smaller pad on which the power button resides. after unscrewing all of them [except the two little smaller ones located on your right edge], unscrew the covers off the RAM compartment and Wireless card compartment. Unplug the RAM and wireless cards. The wireless card has two cables attached to it that run right into your monitor, unplug those. Now you may be wondering why we are unplugging things that arent next to your backlight, well if it wasn't for the cale that runs from your wireless card right into the display, we wouldn't have to go through all this trouble. NEXT, flip the computer over and peel off the smaller pad on which you have your power on button. The remove the keypad and gently pull out the black and gray cables for the wireless unit. [you only have to do this if you need some slack when working with the screen]. Next widen the screen to its max and you'll see 4 dark screws (2 on each hinge). Before you unscrew them, you'll have to remove the data/power line connector located right next to your power switch. It's got this little black thingie you could use to pull it off [unplug it], all the above only allows you to place the screen on its back thus makig it easy for you to remove the screws that NOW open the screen [phew].
Now, once you have isolated your screen, remove all the rubber pads that like the perimeter of the screen [you'll find your screws below them. Unscrew those you'll on your way to accessing the backlight.
As for how to remove the backlight, read through the manaul on this link, I am sure you either have a loose connection, or your backlight really is wasted and needs changing

Why would my HP laptop screen go black?


A few reasons
1) backlight burnt out (or broken)
2) loose or broken cable AND backlight burnt out (or broken)
3) Failed GPU (probably integrated into the motherboard on that model)
4) failed motherboard (same issue above)

Check by plugging in an external monitor- if you get a signal, your LCD need a new backlight (or inverter, an easy fix under $15 USD)).

Cheapest solution is to simply replace the backlight, but you'll have to diassemble the entire laptop lid/cover AND the LCD to get to the backlight at the bottom. (this could be under $20 USD to do). Often similar sized LCD's with different part numbers will work fine in different laptops (meaning, a 14" LCD mady by samsung or LG will be compatible with almost any same 14" LCD made by either, especially if it comes WITH the inverter!)...

Hp dv1000 no backlight, repalced inverter, still no screen


plug in a monitor in the side of the laptop if it shows up then the lcd is bad. Also try and reset the memory by pulling it out and then put it back in if not in all the wall nothing will appear on the LCD.

Hp dv1000 laptop, just replaced lcd inverter, still no back light. You can see the screen is working just no back light. The led is on on the inverter.


You need to verify that you do have 9~12vdc feeding the inverter board. Did you see the backlight turn on for a second? Worst case will be bad lamp.

HP DV1000/screen turns on then turns off.


You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

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

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.

How to swap laptop LCD.


Follow the link given below to a page that will allow you to enter the specific model of dv1000 that you have. Download the maintainance manual for your machine and that will tell you everything that you need to know. Pretty much step by step instructions. Not rocket science and should only take a couple of hours.
Hope this is what you are looking for!

HP Pavilion dv1000 works fine on CRT but no LCD screen


Sounds like the LCD backlight or inverter went bad. More probably the inverter,and that's good because,of the two, it's usually cheaper and easier to replace.
Before considering those,check the lid switch to make sure that it is operating correctly and not stuck down.

http://h10032.www1.hp.com/ctg/Manual/c00312379.pdf there is the link to your service manual, You are going to need to replace the LCD Power Inverter.. It is going bad. They go for as little as 16$ on ebay..
It could possibly be the backlight going as well.. but the first step for your problem is to replace the inverter...
