Hi,

It seems like that it's a hardware problem, your built in display to be exact. I would suggest opening the laptop and checking if the ribbon cable that connects the LCD to the motherboard is seated properly. Disconnect both ends from the motherboard and LCD then reconnect it and see if that will solve the problem. If it will still not work your last option would be to replace the LCD itself.
