MacBook Air charging but won’t turn on

About a year ago my MacBook Air would not turn on. I do not believe any water damage occurred, but still had the issue. After several attempts to figure it out I took it to Apple and paid the money to get it fixed.

They replaced the logic board in October and it had been working great since then...

Suddenly last week while I was using it it randomly shut down and now is doing the same thing. I don’t believe any water damage was sustained (I have only ever dribbled some water on it and immediately dried it off but before it shut down this had not occurred).

I left it for a few days to “die” and charged it again. It fully charges but does not respond when I hit the power button. I have also attempted a SMC reset Several times and no response. The charger indicator light does not change when I’ve attempted the SMC reset either.

What could be wrong? And what can I do??

I already shelled out the money for the logic board to be fixed and I don’t want to have to do so again (the warranty from the replacement from Apple only lasted 90 days)

HELP!
