Hello,

I have had this same problem with a HP DV2000 and the problem is not the contrast light. What it is, is that the laptop thinks that the screen is been shut down that is why the light does not come on. The best way to solve this is to remove your keyboard first.

You can remove the keyboard by removing exactly 7 screws from your laptop back, there are 5 screws located under your battery and other two that are in the location of your RAM'S.

Just open them up and then you will notice that the key board pops out abit then just simply take it up and then just below the keyboard, on the same line where HP brand logo is on your machine there are two small clip types of pind, that you can remove and put back.
There is a clip that is hidden abit under the metal plate, so just try and remove that clip from its place using a needle or any long and thin object.

That will make the laptop not have the problem. But once you remove that the laptop constantly will think that the screen is open even if you close it. then after like a week or two you can put it back and all shall be fine if not then just remove it and keep it out.

You can then set your power options to shut down the screen light every 2 minutes or something like that so as to avoid the backlight being switched on all the time.

Hope this solves your problem.

SOURCE: power comes on but screen stays black

The backlight inverter board may be bad, or worst case will be bad lamp. You should look to see if the cable comes off the inverter board first. You may learn maore here:

Hp entertaiment pc problem display STAYS BLACK BUT ALL LIGHTS COME ON


If the Video Controller fails, the screen will stay black when the rest of the computer runs as it should. To test this, look to the side of the computer and locate the external Monitor attachment. It is a nine pin male outlet. Take a regular computer monitor and attach it to the connection and turn on the computer. If the Monitor acts like your normal LCD screen, then the main LCD screen is bad. If Neither the Monitor or LCD works, then the Video portion of the computer may be defective.

Computer turns on but screen stays black


This is often caused by the screen lights or screen failing. Try looking at the screen from different angles in different light conditions, you might just be able to see the image.

If it worked on a computer at the IT person, it is most likely a faulty graphics card in your computer. You may want to get that checked out.
