Answers :

The problem could be a loose video cable/connector.
\015\012Reseat the video cable or the connector that connects to the motherboard.
\015\012To check if the video card is faulty, connect an external monitor to the video port on the HP, power up the external monitor first, then bootup the laptop. The video will automatically switch to the external monitor and if you see a normal image then the video card is OK and the fault is the LCD screen/video connector.
\015\012If you see a faint image when you view the LCD screen at a sharp angle, then the fault could be the CCFL lamp or the inverter that supplies high voltage to the CCFL lamp.
