Hi, A friend gave is old phone because it not working. After dissembling it I can clearly see that it had been water damage because of the water indicator. It a Galaxy Ace II X. I tried cleaning it with dome alcohol and bought a new battery. After pressing on the power button a can only hear sone crackling coming from the earphone speaker. I tried plugging into a a computer it not detected. Do what should I tried now ? Huge thanks for the help. Update (12/22/2019) Thanks for the answer, I tried to totally submerge the motherboard in alcohol but it still not working. I search for anything that look bad but it doesn’t seem like there any corrosion on the electronic. I took a picture of it. Huge thanks for the help.
This is a hard question to respond, because many things can have liquid damage inside, but this is my personal rule: “Inspect for liquid damage and corrosion, wherever is bad or looks bad needs to cleaned be replaced, if liquid touched the motherboard/circuit board, the same rule wherever is bad or looks bad needs to be cleaned or replaced.”
It looks very hard to fix it on your own. You may try sending it to a pro or a repair center if it is really important for you.
