Then there's the bad caps problem. Almost NONE of these get replaced
even though it's a trivial *component level* repair that doesn't need a
schematic. It seems very likely that more than 99% of LCDs that fail in
this way unnecessarily end up in landfill, when most of the components
would outlive the owner.

blinkenlights,
Modern PCs often give you millions of those.

Modern PCs do have components you can replace individually. There is
some variation, but typically the replaceable components are:
* system unit
* monitor
* power cable (typically two)
* video cable
* keyboard
* mouse
