An LCD screen cannot produce enough light by itself. It needs an additional light source. A Backlight is the additional light source.
A Backlight is a CCFL. Cold Cathode Fluorescent Lamp. Very similar to the Fluorescent lamps, (Bulbs), used in homes and businesses, but on a MUCH smaller scale.
HP Pavilion dv6000z series Notebook PC, is a general series designation. The EXACT model number is on the bottom of the laptop in a white Service Tag.
The HP Pavilion dv6000z series of Notebook PC's used either an LED or CCFL type of Backlighting. Depends on which model it is.
As stated in the above information a Backlight is mounted in the back, or on the side of the LCD screen. The LCD screen is composed of layers. These layers are held together by a metal frame which emulates a picture frame. If the Backlight is a side unit it will be held in place next to the layers, and inside the metal frame.
[Which means the LCD screen's metal frame, (LCD Panel Frame), needs to be opened on one side. This will leave the layers which compose the LCD screen loose. The layers MUST be held in the proper placing when changing out the Backlight. Not an easy job to accomplish]
An Inverter is used to change the power coming from the laptop, to be used by the LCD screen, and Backlight. 90 percent of the time the problem is the Inverter.
The Inverter for the Pavilion dv6000z series of Notebook PC's is located inside the Display Assembly.
The Display Assembly is the 1) Display Enclosure Cover, (Plastic top of laptop), 2) LCD screen, 3) LCD Panel Frame, (Metal frame around LCD screen), 4) Display Bezel, (Thin plastic frame which surrounds the LCD screen in the front) 5) Camera Module 6) Inverter 7) Display Enclosure Cover Hinges (2) 8) Display Enclosure Cover Hinge Covers (2) 9) Wireless Antenna Transceivers and Antenna Cables 10) Microphone receivers and cables 11) Various mounting screws
[The Top Cover for a Pavilion dv6000z series Notebook PC is essentially the Palm Rest. The cover under the Keyboard]
With the Display Bezel removed the Inverter is located at the bottom. (Display Assembly removed from laptop first)

An LCD screen cannot produce enough light by itself. An additional light source is needed. A Backlight is the additional light source.
A Backlight is a CCFL. Cold Cathode Fluorescent Lamp. (Lamp = Bulb) Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale in physical size. (Average size is 3 to 5 inches long, and half the diameter of a No.2 pencil)
An Inverter is used to provide power to the LCD screen, and the Backlight.
90 PERCENT of the time the Inverter is the problem.
Which is a Good thing. The Backlight is located inside the metal frame that hold the LCD panel layers together. Usually on one side of the LCD screen. {Some LCD screens require Two Backlights}
Replacing a Backlight is a job for a trained repair person. The LCD screen is a composite of layers.
The above is ONLY an example. An Inverter MUST be matched to THE LCD screen.
Stating Pavilion dv2000 is only stating the series. The EXACT Product Number is located on the bottom of the laptop in a white Service Tag. P/N = Product Number
Also, there is an HP part number on the Inverter. Match the HP part number to the listing for the Inverter you are going to purchase.
A reputable seller will list THE HP part number so that the buyer will purchase THE correct Inverter.
How to replace an Inverter in an HP Pavilion dv2000 series Notebook PC;
1) Service Manual
I'm going to use the HP pavilion dv2000 CTO Notebook PC as an example. The Service Manual is the same for All of the Pavilion dv2000 series of Notebook PC's,
On this page click on the file name > HP Pavilion dv2000 Notebook PC Maintenance and Service Guide.
After you click on the above link it may take up to 30 seconds, or more, to see the first page. In the meantime you will be viewing a blank white page. The PDF file is downloading in the background.
In the Bookmarks menu to the left, click on the + sign to the left of > Maintenance and Service Guide.
Click on the + sign next to > Removal and Replacement Preliminaries Read up on Anti-Static Precautions
Now go back, and click on the + sign next to > Removal and Replacement Procedures.
Scroll the sidebar down, and click on > 5.12 Display Assembly
Direct information on replacing the Inverter is on Page 152. (Page Number Box at the top of the PDF file, to the right of the blue Down Arrow)
I use a computer pick to ease up on one side of the rubber Screw Covers. You may have a similar device you can use. If you are careful with the rubber Screw Covers, you can reuse them. There is a contact cement on the covers.
Lay them down glue side up on a piece of paper. (They do like to stick to the computer pick, and your fingers, however. Giving you a 'heads-up'. Try to keep the glue side from picking up debris, however)
If you need guidance, no matter what it is concerning this procedure, please post in a Comment.
One more thing that pertains to the HP pavilion dv2000, dv6000, and dv9000 series of Notebook PC's, that I think you should be made aware of,
Suggest you replace the Inverter. A Backlight goes out all at once. 90% of the time the Inverter is the hardware part at fault.
[ An LCD screen cannot produce enough light by itself. A Backlight is used to supply the needed extra lighting. A Backlight is a CCFL. Cold Cathode Fluorescent Lamp. Similar to Fluorescent lighting used in homes, and businesses, but on a much smaller scale
An Inverter is used to required power for the LCD screen, and the Backlight. Boosts power up for the LCD screen, brings it down for the Backlight.

Replacing an Inverter is a simple job. Replacing a Backlight is not. The Backlight is located within the LCD screen assembly.
The metal frame of the LCD screen assembly is removed along the edge where the Backlight is located, to access replacing the Backlight.
In the above list for Service Manual, click on > Display Assembly and Display Latch.
This information shows you where the Inverter is located on a Dell Latitude D620 Notebook PC. The Latitude D620 is part of the Latitude D600 series of Notebook PC's.
You might have either a faulty LCD cable or screen inverter board. The
LCD cable transfers data signal from the motherboard & video card
to the LCD screen. It also supplies high voltage DC power to the screen
inverter board. The screen inverter board works as a power supply for
the backlight lamp mounted inside the LCD screen. It converts low
voltage DC power to high voltage AC power needed for the backlight lamp.

This is almost always an "inverter" or "backlight", which are both relatively inexpensive and easy to replace.An Inverter can run about $60 for the part itself, and a backlight about $5.00 .However to fix either problem ,you will have to take your screen apart. Almost anyone can replace an inverter with some common hand tools and a little care. I would not recommend trying to replace the backlight unless you are highly skilled at screen repair.
The bad news is that this can also be caused by a problem on your motherboard.
You most likely have a defective inverter that supplies high voltage to CCFL backlight. It is unlikely a faulty CCFL lamp because your laptop is approx 1yr. old.
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 the inverter or 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. Check out www.lcdparts.net for parts, repair service and DIY info.
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.
