I remember in the early 1970s my friend's parents had a Hitachi colour TV
and it had a tint control (we had fun tweaking it just before his granddad
wanted to watch the snooker!). I understand that Hitachi didn't pay the
royalty to use a genuine PAL decoder and converted PAL to NTSC and then used
an NTSC decoder (or something like that).

The Sony 18 inch from that era also had something similar but they called it a
hue control. It also had a shedload of wirewrapping between boards rather than
using connectors.

My 1978 Sony 18" had a "Picture" slider control that adjusted the
brightness, contrast and colour contrast together. Useful to adjust to
suit different room lighting. Behind a panel at the front there were
additional colour contrast and either brightness or contrast buttons.
And a tone control (treble cut).

There were also controls at the back - I think you had to insert a
screwdriver through holes - one was "Height" which I had to adjust to
show the whole picture from my BBC Micro.
