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