I am no expert, but I have to imagine it would be quite hard to learn electronic repair without learning some basic circuits.

I've learned a decent amount with some electronics adjacent hobbies, like 3d printing, diy sim racing stuff, mechanical keyboards. Mainly just copying things other people build. Enough that recently I was able to diagnose a broken transformer in an electronic theater chair power supply.
