The monitor screen on your laptop is an LCD screen.
An LCD screen cannot produce enough light by itself. It needs an additional light source.
The additional light source is a Backlight.
A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.
LCD screens are a composite of layers. The layers are held together by a metal frame, much like a picture frame.
The Backlight is usually located on one side, accessed after removing one side of the metal frame.
As stated, a Backlight is a very small type of Fluorescent lamp, (Tube)
Very fragile, easily breakable, and not usually approached by one who has very little, or no experience in replacing.
More common the entire LCD screen is replaced, which includes the Backlight already installed.
A laptop also needs an Inverter to provide power, both for the LCD screen, and the Backlight.
90 percent of the time the fault is the Inverter.
I repeat, 90 percent of the time the fault is a bad Inverter.
An Inverter is cheaper than an LCD screen, and MUCH easier to replace than a Backlight.
Allow me to show you replacing an Inverter on an HP Pavilion dv6000 series laptop.

My premise is to teach, and hopefully save people money.

You can find partlists on HP Partsurfer. But it looks like the inverter is included in the LCD assembly on these models.
If you post the modelnummber I can check if I can find a partnumber at work. It should look something like this AA111BB#CC.
