I have a Lg Chocolate phone with verizon and today out of no where the screen just went to white and I cant do anything with it. I tried to turn it off then on and the same thing happened. Im scared that its died forever and I have a small hope that there is a way to fix it, like getting a new battery ? Someone help ?

I dropped it in water a few months ago and it did the same thing, after it dried out it worked but this time I didnt drop it in water.
