SOURCE: I HAVE A HP DV2000 LAPTOP WITH VIDEO ISSUES , I REPLACED THE MOTHERBOARD BUT STILL NO PICTURE ALL LIGHTS ARE ON AND THE FAN IS WORKING BUT NO VIDEO..

Hook a spare monitor to the video output, usually on the back. If you get a picture it means the inverter board is bad, or the backlight behind the LCD display, check to make sure the round video cable is plugged into the motherboard. But, if the symptom is the same for both screens, the problem is the Video Graphics Card normally built into the motherboard. If the connector to the LCD is damaged that would explain the issue of no video.
