Re: TV system differences?
In the US color sets retained a physical hue control until ICs replaced
discrete transistors. However, it slowly moved to a hidden place.
Even my current 55 inch Sony LED set actually has a real hue control
in the hidden service menu ... it rotates U and V. And the correct setting is not how it came set from the factory, though it has remained perfectly stable.
I can't get color right without it. One suspects that Sony uses "test subject panels", different for each country, to set everything "to local taste" instead of correct.
