The code, the manufacturer's checks, and the line where you stop

What every code page carries

• One official page, linked and dated

  The manufacturer's URL, its last-updated date and the day it was read sit in a provenance table on every page.

• The checks in the manufacturer's order

  Drawn as a decision tree and listed with the brand's own detail. Nothing is reordered or added.

• A red box that is not negotiable

  Where the page says to request service, the tree ends. The page also names what it deliberately does not cover.

• Same code, other brands

  Whether another verified brand uses the same code for something else, built from the site's own data, so you never apply LG checks to a Samsung.
