Question about HP Pavilion dv4000 Notebook

1 Answer

Dark Screen I have an HP pavilion dv2000 that I have just bought from the US. When I turn it on the screen is very dark. The screen birghtness is on full. More strange, when I pu *** onto a setting with a moon picture on it (presumably night mode or something) it flashes full colour (as if a normal computer) then goes blank, which I uess is the end product of that button. It's realy frustrating as it works fine but I just can't see it very well!!

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,

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,

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.

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,

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 :-

Dv4000 hp pavilion dark screen


Have you replace the lcd inverter? if it works on external monitor, given the screen is new, then it leaves the inverter. Usually in the case of dark screen, it should be the first thing to check/replace.

My screen went dark !


hello sir
To state the obvious, make sure the brightness is turned up. This is usually a function key on the keyboard. If this doesn't accomplish anything, then the backlight on the lcd may be damaged, and the lcd will have to be replaced.
thank you

the lcd lamp driver (inverter is likely bad)
inverter provides the high voltage that the lamps need.
as it heats up it has the symptoms you describe.
