Question about Gateway Computers & Internet
I don't know any laptops that have separate video cards, they are integrated with the motherboard.
To test if the video card is faulty, connect an external monitor to the laptop's external video connector/port and boot up your laptop. The external monitor may automatically display images, if not you may have to press the blue Fn key plus one of thr function keys to switch the video output to this video port. If you see a clear image the the Video card is OK and the LCD is faulty.
Is the display garbled or it is very dim?
If it is dim and the image is OK then the problem is associated with the backlight. It could be the inverter that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty and 80% of the time it is the CCFL lamp.
The inverter is easy to replace but the CCFL lamp requires more work and soldering skills.
