It sounds like your backlight in the LCD screen has died. However your system should work with an external monitor. When you connected up the monitor to the VGA connector did you change the settings on the system to output to the VGA output ?
Try connecting the monitor before the computer is turned on - then once booted hold the Fn key and press F7. Then pause then press Fn and F7 again to see if you can get the external screen to show your screen. It sounds like a dead back light though.

Im on a laptop and the back light usually just flickers but the screen has gone dark and i have to use a flashlight to see the screen.


Replace the Inverter, rickeyjsmith.

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.

http://solutions.3m.com/wps/portal/3M/en_US/Vikuiti1/BrandProducts/secondary/optics101/

A lot of times the LCD screen is replaced for Backlight replacement, because some LCD screens require this.

Backlights cost more than an Inverter, and of course an LCD screen costs much more.

This is an example of an Inverter for an HP pavilion dv2000 series Notebook PC,

http://www.buy.com/prod/new-usa-lcd-inverter-hp-pavilion-dv2000-dv2100-dv2200/q/sellerid/23962916/loc/101/217117085.html

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,

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&lang=en&product=1817074&

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,

Hi, my hp dv2000 screen is blank when I turn it on. It hums and lights up like it's supposed to, but the screen is completely blank! What do I do?


Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.

My HP Pavilion dv2000 turns on, but screen is black


If the laptop appears to boot up but the LCD screen is black, then the problem is a back-light fault caused by either a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to determine the fault and fix :-

Doubt that it's the inverter. Sounds more like one end of the LCD cable has been knocked loose. You might wan to check those.

Hp pavilion dv2000 notebook will not boot up


hi,
i m in Hong Kong. The stupid HP repair center charged US 90 just for inspection!!!!! They they said the whole motherboard had to be replaced, thts additional US 630 dollars, the thing is just 1.5 yr old. They also said i don get to keep the broken mother board after replacement. This is simply irresponsible, unethical, sleazy and UNJUST!!

Thanks. right now the computer is fixed for US70. when i hv time, i'll open it up and see if i can figure it out how it was fixed. The shop suggested tht the computer wont last too long. This is such bad quality for HP... Sorry, i hv to do the following for other victims to find this easily:

If You want test lid switch, just connect A+B together for a monent!
If the monitor flashes on...? Lid switch is faulty.
It is too dificult to change the lid switch, so the easiest way is connect these pins together forever. :))

Dont forget to turn off your notebook... he wont sleep anymore ;))
