Did you know?
There was a time when every piece of electronic or mechanical equipment you purchased came with a complete schematic diagram enabling you to diagnose problems and buy any replacement parts you might need to repair it at any point in the future.
Ex: my Apple ][+ came with complete schematics. So did my first stereo amplifier.
This is the way. -

This is the way.I remember television sets had complete schematics inside. And if that wasn't enough, complete troubleshooting guides and parts lists at the local library.

This is the way.@jik Yeah, my parents' generation: most stereos came with schematics. And washers and dryers did too.

This is the way.@jik Stanford Research Systems still does this for most, if not all, of their lab equipment (although firmware source code is not included so if the processor or flash is dead you're out of luck unless you can get a replacement from them).
But for anything else, component level repair and troubleshooting is very doable.

This is the way.@jik Pro tip: up until the 1980s it was not rare for there to be a slip of paper inside the appliance with the circuit diagram(s).
Ovens, stereo amplifiers, turntables, clothes washers, etc.
And unless someone took it out, those older pieces of hardware STILL have them inside.
Sometimes loose, sometimes pasted on to a surface.

This is the way.@jik I have binders with beautiful schematics for a lot of my equipment, this is almost the entire reason why I prefer stuff from before 2000.
It's amazing how possible it is to repair things when they don't use a bunch of microcontrollers with secret firmware and publish actual schematics.

@ai6yr you are a role model the current era needs

This is the way.@jik I didn't know that, and tbh, the fact that my first reaction was "that is so wild!" is probably indicative of why this lack is such problem now. Goodness.

This is the way.@jik I once rescued a moped from a neighbor's junkpile, found that it was sold through the Sears & Roebuck department store, and was able to order specific carburetor parts from the exploded view in their catalog to get it going again.

This is the way.I seem to have a recollection of it also coming with an annotated 6502 assembly listing of the ROM, or am I mis-remembering?

This is the way.@jik It really annoys me when I'm trying to work on a device (usually audio) that was discontinued like 15 years ago and the manufacturer won't give me a schematic because it's 'proprietary'.
I often end up finding that there's nothing really proprietary in there, but there are some serious design flaws. I then assume that's what they were trying to hide.

This is the way.@jik I think about if that did continue and if manufacturers would be interested in including a small booklet of schematics alongside your warranty card or even if it'd be feasible. We've come a long way from the Apple II+ after all.
