Water damaged G2 D802

Hello, I've recently water damaged my g2. It shut down in about 20 min and when trying to power it on the red led is blinking and nothing happens. I removed the logic board and kept it for a week in rice and successfully managed to boot it and save my data but it went silent shortly. Now the same red led is showing and the LG logo when I try to power it on.

Water damage is pretty serious but I just wanted to ask if there is anything I can do to try and fix it.
