Chosen Solution

Good afternoon. Need help identifying a component that has deteriorated due to oxidation on the board. There were two faulty components an inductor and a component that appears to be a transistor but is very small. There are other similar components on the board, but I can’t identify them. The first image shows the location of the component, very close to the coil that is damaged:

Here’s an image of the component similar to what’s missing:

The rest of the board seems to be ok, just missing this to revive this monster! Thanks to anyone who can help!

wagner.m.v that is reference designator Q7800 which is a SSM3K15FV N-Channel Mosfet in a SOT-723-3 package.
