We should deal with the water damage first. That may fix the issue, and if you don't address the water damage, you'll have bigger problems.

I have already took out all the parts and bath my logic board with 91% alcohol and let it dry for almost 48 hours and I dont find any mold or anything on the logic board . I have two liquid which turn into RED now but other than that nothing else.
