Hi,

Try connecting an external monitor to see if you still get a display.

If you do then good, the motherboard is probably OK as far as the video goes but maybe not the backlighting power supply and most likely only the screen will have to be replaced. If you don't get a display, then at the moment you know that the motherboard has a problem and that the fate of the LCD screen is an unknown.

By reversing the cable incorrect power levels would have been connected to components that weren't designed to cope with them and most probably would have destroyed them, resulting in no display.
