Hi,
Your screen is:
15.6"
1366 x 768 Resolution
Widescreen
LED Backlight
WXGA HD
40pin BOTTOM LEFT connector.
But HP Pavilion DV9000 is '''17.3" '''.
The part number of the screen for your laptop must start like this x156.
x - this is manufacturer, 156 - 15.6"
LTN156 - samsung, LP156 - LG, Philips...
Your search must look like this: LED 40pin. screen 156,
or you can write LTN156, LP156, N156... (Samsung and LG are more popular manufacturer of this part).
