Possible Faults

• Loose connection between the video cable and the LCD screen or a bad video cable
• Faulty or bad LCD screen
• Faulty or bad VGA card

Solutions                  

• Connect an external computer monitor to the laptop, to do this just connect the monitor to the VGA port at the back or side of the laptop, then switch the video output from internal to external mode by holding down the Fn + F (that has a TV icon on top of it) keys. On some laptops, to switch to external mode, you have to restart the laptop after connecting it to the external monitor, so that it can detect it. If the external monitor displays fine, then you have a problem with the LCD screen or video cable, but if the image displayed on the external monitor is the same as the one displayed on the laptop LCD screen, then it means that your laptop LCD screen is OK.

• If the external monitor image is the same as the one on the laptop LCD screen, then it means that the laptop’s VGA is faulty and needs to be replaced or the motherboard itself needs  to be replaced, in situation where the VGA is permanently attached to the motherboard.

• In some case, the cause of the problem might be a loose or faulty video cable. To check this connection, you have to disassemble the laptop LCD screen panel.
