Bit like when the early colour TVs had to be 'professionallty installed' as the early shadow mask tubes were extremely sensitive to external magnetic influences like the earth's field.
The convergence had to be adjusted 'in situ' ,and if they were moved, even slightly, it all had to be done again.

I'm sorry, WHAT? The whole shebang is so sensitive that it's affected by the local magnetic variance?

Cathode ray tubes are the most insane consumer electronic of all time, except maybe the VCR. It's an electromagnet-driven particle accelerator that blasts electrons at the inside surface of a massive vacuum chamber made of dozens of pounds of thick-as-fuck glass powered by a deadly capacitor.
