1. Connect an external monitor to your laptop and check that its' display is OK when the laptop is turned on with the lid open.
2. ''If the external monitor shows a display'' and the laptop's LCD screen doesn't, shine a torch at an angle close to the LCD screen and see if you can detect an image on the screen at all. It will be very faint, so doing this in a darkened room may be an advantage.
If you can see an image (the same that is on the external monitor) then you have a backlight problem. This could be caused by a faulty backlight or a faulty backlight cable.
Here is a link to the [http://h10032.www1.hp.com/ctg/Manual/c02641795.pdf|service manual] for your laptop, which may be of some help, if it is the backlight (or cables ) that is the problem. It describes how to access them for removal etc.
