>>30685277>>30685697Leaving water damaged electronics in rice does nothing. I don't know how this shit started, but it's the same as if you were to do nothing.
The only actual fix would be to open it up, clean out all the liquid, clean any corrosion off the board/flex cables, maybe reflow the soldering on the board, put it back together and hope for the best.
Even then it's kind of a 50/50 chance it'll still work. Depends on the extent of the damage and exactly what sort of liquid got in it. Some liquids are more corrosive than others.
Water damaged LCDs and speakers aren't really fixable either so they'd just need to be replaced.
