I got a hand me down $700 new espresso machine that stopped heating up, fixed it with a jumper (the power circuit got fried during a storm) and it worked perfectly for 10 more years.
When it comes to digital stuff? Good luck. When I comes to regular dumb electronics, just check for burns and busted capacitors. 90% of the time that'll be your problem
Everything around the digital stuff is the same, troubleshooting wise. Does the power go where it needs to? Is it changed how it needs to be (stepped up or down, etc)? For digital stuff... yeah, code is usually locked down so you can't just buy a chip and flash it and replace it. Though, I've considered doing the old school hacker thing and adding in my own MCU setup dead-bug style before...
Yeah, at some point, you need an electronics microscope a la EEVBlog, and a really fine tipped iron (fine tipped everything really). I've ton a bit of bodge wiring on SMD boards though for prototyping. My fanciest work was hooking up a WiFi module with equal length wires since it was fast, parallel lane SPI (SD something, can't remember what that protocol is called. EDIT: maybe it's just called "SD SPI", according to reading on wikipedia). The wires were stiff enough to hold the module up in the air though.

I wish I knew how to make basic repairs on electrical stuff. I can put up a lamp and that's about it. How do you learn more?

I meant low voltage boards with smd components lol, replacing stuff on those is really hard

YouTube can get you pretty far for basic electrical know how and repairs, I think.
