Submerged Fitbit Surge, screen/liquid crystals flicker - Any Fix?

Hi there,

I stupidly took my fitbit surge into the ocean and now the screen flickers and the liquid crystal displays appear unfinished ie. have streaks through them. I can still control it (just) and find my way through the menu's.. I have tried putting it in a bowl of uncooked rice to draw out any moisture but to no avail..

Any ideas or is this a bin job?

Cheers in advance.
