Anytime I play a certain part of a game it shuts off

Anytime that I play a certain part of a game such as when I try to make a advanced entrance in wwe2k19 it shuts off anytime I play nba2k22 it shuts off and we thought that it was the fan so we bought a new one and took it to a place that can put the fan into the ps4 but they said that they couldn’t do anything because when they opened it they saw that it was water damaged and if they tried to replace it, it would destroy the motherboard or somethin. So if anyone knows anything that I can do to make it stop shutting off other than that it’s water damaged it would be great.
