Why is my MacBook Pro screen black?

I have a mid-2009 MacBook Pro 13". Suddenly when I woke up my laptop from sleep the screen was black. I did a forced shut down and when I turned it back on the screen was black again. I know the laptop works because it boots and I here the initial chime when it is turned on. The keyboard works as well, the light turns on and the Caps lock key turns green when pressed. When I put my finger in front of the camera, the keyboard light brightens, I know the camera and display are connected separately but maybe it could help to know.

I already tried every solution I could find and nothing works. I did the SMC reset, the PRAM Reset, I even disconnected the the screen cable from the board and connected it again and nothing seems to work?

Could it be something related with the LVDS cable or the inverter cable?

Thanks a lot in advance!!!
