 Hello jarkk, I believe your problem is with your backlight inverter. the hard drive should be installed for this process of checking it on an external monitor. with the hard drive removed it will not boot to the operating system. with the drive in, use the external monitor. if the monitor works when plugged into the external monitor plug, this will eliminate a bad video card. if the screen is still black on the laptop screen, replace your backlight inverter. the last case cenario is to make sure your backlights are not burnt out.

vast posts here on black screens of deathh
the screen is 100% black and never once shows text or that HP logo. 100% dead black, then that is the screen back lamps dead
as most long ago did, go dead , just not yours.
called the CCFL lamps dead.
ok the battery out test1
the other check is the fan is the fan blowing, it must or the CPU overheats fast and (it shuts itself off, like magic (intel inside)
see slide show here for Laptop link packup causes.overheated

see flash light test. there. on test one, do that.?
see test #1 (battery out, ac pack connected and working)


http://pcdied.com/black-screen.html#Basic-basics-101

if the flash sight trick passes, (see data) ask how to fix that
or read the service manual at HP.



see the list of HP , with CCFL here. dv9000 is it.

Dv 9000 what lcd fits it


1) 17 inch WXGA (1440 X 900 Pixels)

Here's an example;

MAIN THING > Match the Part Number on the back of the LCD screen to the one you are going to purchase.

It isn't just whether the screen is the correct size, and dimensions. Whether it is a glossy finish, or matte.
It is that the cabling on the back of the LCD screen is correct, and the LCD screen matches the Inverter that is installed.

My hp pavilion dv9000 17 power on but see black screen


If your 9000 is under two years old, you should contact HP customer care and have unit serviced under warranty.
HP has had allot of problems with the 6000 and 9000 units and in response has offered an additional year from date of purchase.
Its worth a shut. Doesn't cost a dime.
Hope this information has helped you.

1.remove the battery and then press the power button for 30 sec.Again refix it and check.
2.If windows sound is there then this mught be the issue with display.

3.If there is no windows sound might be the issue with RAM so please get it checked.

Hp pavilion dv9000 blue lights on won`t boot stuck just cli


Sounds like the harddrive went bad.
Some people call it the click of death.
Put the laptop to your ear near the harddrive and you will hear the clicking coming from there.
Good news is that it's easy enough to change the harddrive.
Bad news is you lose all your data to this point.
I hope this helps and i'm sorry that happend to you.

Hp dv9000 will not start up. blue lights are go


you get a black screen right, nothing at all then no bios, no logo, nothing at all?
Do you get any beep codes and if so in what order?
did you try different ram?
First try to plug your laptop to an external monitor. If it works, you screen is bad, if it doesn't you probably need a new motherboard.
