I would put it to them that the replaced pcb should itself have a 12

Isn't it part of the consumer laws (or something) that if something is
repaired or replaced under warranty, then the repair or replacement is
only valid for the duration of the origonal warranty? So if I buy a
widget with a standard 12-month warranty, and it fails after 360 days
and I get it replaced, then I don't expect to get a further 12-month
warranty out of it?

Different matter for a paid-for repair or replacement undertaken out of
warranty.
