Spilt coffee, fan spins when connected but doesn't start

I spilt coffee on my Macbook air from 2017 and it worked for a while afterwards. But now it does not start at all. When I plug in the charger the fan spins but nothing else happens (starting doesn’t work). I have cleaned the logic board with isopropyl alcohol but it still doesnt work. Any idea on how I should go about identifying the problem and fixing it? Is it even possible fixing it?
