Please attach an external monitor to your system and let us know if the picture is normal on the external monitor.

Then we know it is from the connector on the mother board back to the screen. It could be the cable was crushed or pinched but moving the screen back and fourth usually changes the display if that is the problem (the exception is if one wire is complete severed).  The power inverter usually just darkens the screen when it fails. So that leaves us with the screen probably being bad.  Try laptopscreens.com .  They have videos on how to replace screens and I believe they offer an install service.  If your laptop is still under warrantee, contact HP customer support and try to get a replacement or repair order.

I brought my laptop to day its only 4 hrs old I did what was suggested here AND IT WORKED should I take it back to where I brought it - it keeps doing it between screens but if I move the monitor on the lap top it corrects itself to a nice crisp screen if I have to take it back I will not be impressed
