I am changing out a display on a pavilion laptop and

problem with motherboard replace motherboard

alejandro,

An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Very similar to the Fluorescent lamps, (Bulbs), used in homes and businesses, but on a MUCH smaller scale.

HP Pavilion dv6000z series Notebook PC, is a general series designation. The EXACT model number is on the bottom of the laptop in a white Service Tag.

The HP Pavilion dv6000z series of Notebook PC's used either an LED or CCFL type of Backlighting.
Depends on which model it is.

http://www.screentekinc.com/backlight-ccfl-led-explained.shtml

As stated in the above information a Backlight is mounted in the back, or on the side of the LCD screen.
The LCD screen is composed of layers. These layers are held together by a metal frame which emulates a picture frame. If the Backlight is a side unit it will be held in place next to the layers, and inside the metal frame.

[Which means the LCD screen's metal frame, (LCD Panel Frame), needs to be opened on one side.
This will leave the layers which compose the LCD screen loose. The layers MUST be held in the proper placing when changing out the Backlight. Not an easy job to accomplish]

An Inverter is used to change the power coming from the laptop, to be used by the LCD screen, and Backlight.
90 percent of the time the problem is the Inverter.

The Inverter for the Pavilion dv6000z series of Notebook PC's is located inside the Display Assembly.

The Display Assembly is the
1) Display Enclosure Cover, (Plastic top of laptop),
2) LCD screen,
3) LCD Panel Frame, (Metal frame around LCD screen),
4) Display Bezel, (Thin plastic frame which surrounds the LCD screen in the front)
5) Camera Module
6) Inverter
7) Display Enclosure Cover Hinges (2)
8) Display Enclosure Cover Hinge Covers (2)
9) Wireless Antenna Transceivers and Antenna Cables
10) Microphone receivers and cables
11) Various mounting screws

[The Top Cover for a Pavilion dv6000z series Notebook PC is essentially the Palm Rest. The cover under the Keyboard]

With the Display Bezel removed the Inverter is located at the bottom.
(Display Assembly removed from laptop first)

The Windows administrator or users password can be removed or changed with the Hiren's boot CD - Click on one of these link to download.
http://www.hirensbootcd.net/ or http://67.20.82.163/
Use a computer that has Internet access and download and burn onto a CD. Then boot-up this CD in your computer and select password removal and follow the instructions.

If the screen can not hold when you open the laptop, you need to change LCD display hinge. You can buy from here.

Dear John,

do you hear beeps from the laptop? if yes there could a problem with RAM module. if so changing RAM module will solve the issue.

Also try connecting an external monitor. to check if the display is not faulty.

it sounds like your hard drive is having issues. it may not be dead, but one of your boot files is corrupted. try starting the computer from your windows disk. and select the repair option. if you cant get any farther or get a read error your hard drive is dead.

How long have the colors on your display been "reversed/inverted" and looking like a negative....... Did you drop or damage the laptop in any way (sudden shock/bump)? Also, has it been allowed to overheat (if you run the laptop while it is sitting on a soft surface such as a bed, pillow, couch, etc it can allow the motherboard to overheat because it cannot get the airflow through the cooling system through the fan/vents because they are blocked). Have you checked to see if your laptop is included in the "HP Service Enhancement" program???
