has everything worked out?
then it is a hardware issue, it could be a malfunctioning control board on the LCD screen or a faulty cable from the control board which is located on the backside of the LCD monitor that runs through the hinges and connects to the main board. the LCD screen will need to be replace by a local repair shop, a LCD screen will cost you between $100-$130. If it's the cable, it will cost about $15. My suggestion would be to take it to a local repair shop and have them evaluate the problem.
