Hello, and welcome to Toyota Nation!
I'd start with the battery cables as it's often the simplest problems that go undiagnosed. I've seen this before where a vehicle is electrically dead even though the battery is known to be good. Take both cables off, clean them and the battery posts with a wire brush, then reattach them and see if you have power. If not, continue from there.
