Here in Brazil, in the 80's, (probably still happens today) you could buy suitcases filled with many pages of reverse engineered schematics of popular TV and radio sets. If you had any problem with your TV, would could take it to a workshop, the technician could diagnose it, query the schematic of that specific model and replace any defective part.

You could in the us too. However that soon stopped as solid state became reliable enough to rarely need repair.

  Aside from the pesky capacitors, but then you don't need a schematic to find the part surrounded by burned PCB. It's is a great shame how many LCD's have been landfilled for want of a part that costs nickel.

    There's so much of this. Think of how many perfectly good battery cells from powerbanks end up in landfills because of cheap micro USB connectors that snap off the PCB.
