A footnote is that field replaceable units (eg parts) have become ‘large complex units’. Once upon a time way back a tech could find a blown capacitor and replace it, or a worn out valve, but no more. Now it is the entire mainboard full of surface mount devices that require special tooling, skills and purpose designed diagnostic equipment.
The time and equipment to isolate a fault let alone repair it could cost more than replacing the product so many warranties are replacement style these days. ‘Right to repair’ and ‘Can We Fix It?’ are other Community topics.
