       I mean, Rods, many a time I have seen dud chips with nary a mark on them but yet indubitably not performing whatever it was that their maker had intended them to do.

       Large Scale Integration. Basically, a huge chip, with lots of transistors on it.

       How about adding a GaAs layer on top so as to provide built-in indicator lights?

       The larger chips get, the more difficult they are to test. Therefore modern LSI chips already have some extra circuitry devoted to improving their testability.   

       Added circuitry to test the chip on power-up and display the results on an attached LED or a dedicated display would not add much complexity.   

       Modern electronic appliances are fast becoming "single chip" designs, so all this may become redundant as replacement alone works.
