Can you shut it down and restart. Sounds like your backlight is out. Looks to me like you need either a backlight or a new inverter. Your LCD is okay as long as you can see your icons etc. Of course first try to shut it off and restart after and see if that will resolve the issue. http://www.batterycentury.com/gateway-md2614u-inverter-p-185670.html has the inverter. Hope this helps to clarify this a bit. Good luck and let us know what happened.
