These instructions explain how you can remove the LCD screen and replace the backlight bulb (aka CCFL tube) in a HP Pavilion zv5000 series laptops. Also, this disassembly guide should work for Pavilion zv6000 series.
Backlight bulb failure symptoms.
For about a month or so, my back light starts off as red on startup and slowly returns to normal (white). This can take as much as 30 seconds to a minute. Much recently, my backlight has been turning off randomly, but the frequency has been slowly increasing. As of yesterday – I noticed a high pitched hum sound just before the light kicked off. My light would come on instantly if I hit the screen position switch. And lastly, if I turned the brightness down, most of the symptoms disappears – except the back light had a red tinge to it.
If the backlight bulb in your laptop is failing, you have two options:
1. You can disassemble the display panel, remove the LCD screen, disassemble the screen and replace the backlight bulb. The backlight bulb itself is not expensive, you can find it here for about $15-20, but it’s hard to replace. The backlight bulb is located deep inside the LCD screen and you can easily damage the screen during the disassembly process. I wouldn’t recommend this repair to a novice. I would attempt replacing the backlight lamp only as a last resort.
2. Replace the LCD screen. This repair will cost you more but it’s much easier to replace the whole LCD screen. You can find a new or used LCD screen replacement or other display parts here.
Also, you can use this instructions for replacing the video cable and display hinges.

however the bulb should always be replaced when the inverter is replaced
I cannot agree with this statement. You can replaced these two parts separately from each other. If your inverter board is dead but there is nothing wrong with the backlight bulb, you can replace just the inverter.

Static electricity can kill your laptop. I recommend wearing an anti-static wrist strap while working with internal parts of your laptop.

my Intel presarioa V3000 Comaq laptop crashed. I got it fixed but now when it is running and I close the lid (or when I shut it down and it is in process of shutting off and I close the lid) there is a high pitched humming sound coming from the left back vent on the back of the vent where the hinge is near the cooling fan. the computer guy says this is normal and it means it is working but what is strange is that when I close it and it is running—and I put my hand on the computer or near it the pitch sound changes with the movement of my hand. Is this because the rotation of the fan is interacting with magnatism or something in the screen and the electro magnatic fields of my hand?
weird.

Lu,
It’s not a common failure and I’m not sure what’s going on.
Maybe the high pitched sound coming from the bottom of the display panel, where the inverter board is located.
I’m thinking about inverter because the said the display has to be closed.
When you close the display, the backlight lamp goes. I’m thinking maybe the noise is coming form the inverter when it’s not loaded. Just a guess.
