Changed the battery on my 2ds and now its not charging

A friend brought me a 2DS that charged but wouldn't turn on. The console had a dead battery, which I replaced with a new one.

It was already turning on and everything was working fine, but then I realized that the console was no longer charging.

Now it doesn't charge and the orange LED doesn't light up, with the new battery, the old one, or without a battery.

Fuse 1 and the charging port are conducting electricity, so I don't know what the problem could be.
