I learned basic electronics repair from modding and building arcade controllers, aka Fightsticks. That eventually evolved into Game Boy repair, and iPod retrofitting, and electronics restoration. It's kind of like cooking; find something you want to make, then follow the directions, and then make something else, and eventually, you'll come across a problem that you have the foundation to solve.

The most basic core of practical electronics repair is that there are things that should be conductive and things that shouldn't be conductive and you need to figure out how to do either.
