Sounds like the screen is going bad. Isolate the problem by plugging an
external monitor to the laptop. Borrow a monitor from a neighbor,
friend, relative or co-worker to plug to the laptop. It can be
any kind of monitor even the
old big fat
crt monitors as long as it has a vga cable to connect to your computer's
vga
port. If the Borrowed monitor does not show the black lines and snowy
background, that proves your video card is ok and the problem is
your lcd screen. If the borrowed monitor shows the same black lines ans
snowy background it means your video card inside the
computer has the issue.
The video will show
on most systems when you reboot without you having to do anything. Some systems
will require you to hit the FN (Function key) + F1 thru F12. Hold down
the FN key then hit the correct key for displaying on the monitor (F1 thru
F12). The correct key will normally have CRT/LCD on it or it will have
the icon of a display.

before you spend $200 for a new lcd screen; may I interject; Please test your computer by hooking it up to another monitor if you get the same result; place your computer in the freezer for about an hour then start it as this model of computer is famous for overheating the nvidia video chip also the tiny fluorescent tube called a cold cathode has beeb found to glow red when about to fail the cathode can be purchased onlin at: laptoppartsdirect.com or, e-bay almost always the only reason to replace you lcd is: breakage or, bad pixels.

There is a Limited Enhancement Program that includes this model. If you are in the US call 1-800-474-6836. If you are outside US check the HP.com website and search for the Limited warranty enhancement Program.
This is normally a video chipset issue that is embedded in your MB. If your notebook is part of the program, hp will shoulder the repair cost for the MB replacement.
Please vote, Thanks!

Sounds like the NVIDIA chip. I had a guy on ebay fix mine a month or so ago for a real good price but I wasn't able to find the listing to give you the information.
