Hi,
Generally the problem is caused due bad LCD inverter cable. Kindly run the LCD diagnostics
How to Run diagnostics
1. Shut down the computer
2. Disconnect the AC adapter and Battery
3. Press the power button for 10 sec.
4. reconnect both AC adapter and battery
5. Press FN key+ power button
6. Follow the screen prompts.
If the LCD problem is shown in diagnostics your screen would have to be replaced.
Thanks for using Fixya
