No it doesn't solve all the problems, but how many TVs now sit in the dump because of the failure of some 1 cent part that nobody could diagnose even if they wanted because they would have to reverse engineer half the board, rather than probe a few different points on the board?
Appliance repair use to be big business. Did it stop being so because washers and TVs and vacuums became too complicated to understand, or the parts went up in cost, or because $1000 is considered cheap enough of a device to be considered disposable? No. They stopped existing because appliances stopped coming with the reference materials to repair them in a reasonable time and parts are obfuscated from their source so people don't even know what their broken part is half the time. Is that a thermistor, a capacitor, a diode that blew up? Have fun spending the next 2 hours tracing the obfuscated part number down through 5 different suppliers to figure it out because you obviously can't test a broken part and there is no schematic to look at and identify it from.
Major appliance repair is very much still a thing, and manufacturers share repair info under their partner programs. But this makes sense because shipping them back for warranty is prohibitively expensive and people are willing to pay a few hundred bucks to fix a couple thousand dollar appliance. They’re still not doing component level repair, because module replacement is still cheaper and more reliable.
Small appliances and electronics are not repaired as any more much because:
1. their real price has cratered over the past 50 years
2. they have more integrated and specialized parts that simply aren’t repairable or available
3. They have fewer mechanical parts prone to regular failure or which pay the bills for repair shops (belts, timers, etc)
4. They are far more complicated than their predecessors, and therefore more complicated to diagnose even if you have a schematic
But yeah, when everyone’s washing machine has a belt transmission and a clunky mechanical timer, they failed all the time and there were repair shops on every corner. But these places weren’t doing the type of work akin to SMD rework on a digital circuits.
