Hi shagger, welcome to BC.
Most of the HP and Compaq 17.1" WXGA screens use two CCFL backlight lamps. However, that particular model may only have one. Below are the full optional replacement screens for the DV8000:Example 1Example 2
The only way to know for sure how many it has is to take it apart and get the numbers off the back of the lcd.
Replacing a backlight lamp on a laptop is not for the faint of heart. It is very easy to damage the screen and in most cases you need a couple of very fine specialty tools just to disassemble it. It is not visable by simply removing the lcd itself. It is "inside" the lcd. You cannot
touch anything in there with your bare hands. You will need tight fitting rubber surgical gloves. If you're going to go that far, you always replace the inverter at the same time too.
Here's a few pics of what you'll be looking at when replacing a backlight lamp on a typical notebook:
