Try to connect to an external monitor and see if this give an image. If it does, then the Inverter / backlight or possibly the VDU cable on your laptop is damaged.
If it does not, the issue is most likely a failed graphics chip (common on these models). You CAN get the chip "reballed" but this will cost about £70.00, and not guaranteed to last

Try moving the display to different angles in bright environmental light while the computer is on. Look closely at the display. If you can see a faint image, the power inverter for the backlight has likely gone bad.

    So what is the solution? Does the entire display require replacement or can the power inverter need replacement? is this a replacement that can be done at home?

Generally this problem is due to contact/loose wires connected to your hardware components but the pile of dust may occasionally prevent the visual display.

HP Pavilion dv7 won't light up


Connect an external monitor to the laptop. Power up the monitor first then the laptop. You should get a normal Windows display if the laptop is OK. This indicates the video card is functioning normally and you most likely have a faulty LCD display screen.
Get back to me with the results of this and any error messages and I might be able to advise the next course of action.
