It sounds like the LCD on your screen may have burned out. Here's a few things you can try to verify if that is indeed the case:.
1. Unplug the power cord and take the battery out of the laptop. Then, press and hold the power button in for at least 30 seconds. That will drain the residual power from the system. Then, plug back in only the power cord - the battery should still be out, then try to turn the computer on. See if any video occurs at all. If the screen is entirely blank after a few minutes, go ahead an unplug the power cord again to turn off all the power to the unit.
2. Put back in the battery and power cord, and plug an external monitor or projector into the laptop. Turn the laptop on and then close the lid immediately after pressing the power button. See if any video will appear on an external video source. (IE monitor or projector). If video does show on the external monitor, then open the LCD screen back up and see if any video shows there.
3. If the video does not show on an external monitor at all, try the hot keys/function keys to swap the video output. (On your model of laptop if should be the F4 key.)
4. Also try the screen brightness keys. Press and hold F3 to increase the brightness on your laptop.
If these steps all fail - then most likely, the LCD is dead. You will need to either call HP to set up a return to depot repair - or contact a certified technician to repair the laptop for you. The number to call HP is: 866-234-1377. (This can be expensive if your laptop warranty is expired.)
I hope this helps you out!
