LCD Back light doesn't come on anymore after accidental water spill.

Hi All,

My cat spilled a glass of water that was on an ottoman where the macbook air was cause a puddle to form right where the laptop was sitting. I don't know how long the back part or the laptop was under the water we were gone for about 2 hours. I cleaned it up dried it stuck it in a bag of rice for 48 hours. The macbook air turns on and if i plug in an external monitor to it we can use it but the built in monitor no longer has light. If I shine the light through the back apple logo I can see the middle of the screen and am able to barely click menus and other stuff. I have been reading all over the net for the last 4 days and looks like it may be a fuse problem but am unsure since most of them don't sound like my exact situation and also other mention it may be the logic board may be damaged. I have read that it may be a good thing that it was just filtered water. I have taken pictures of the macbook air logic board. Would i be able to just replace the screen? my apple care expired 12 days ago although i dont think it would matter to apple since it says liquid damage is not covered.

please help, thank you
