A capacitor burnt on the motherboard of galaxy j2

[AC Question]

Just yesterday I dropped my phone in water. I pulled out of there but forgot to switch it off at that time.I evaporated it from outside. After an hour it stopped working. I restarted the phone and it hanged at samsung logo. I tried to boot into recovery mode but it was not booting into recovery mode as well.
So I decided to open the circuit and see whether some water drops are still there, instead I found that one of its capacitor has burnt there at right top corner.
So can I buy it from some store or will I need to replace its motherboard entirely?

A remote diagnosis is hardly possible. But in mind that there may be other damage of which you are unaware, and that water damage tends to be progressive over time.
