A Question about PAL television sets

[dtuomi]

I was reading and replying in another thread about PAL implementations and as often happens I was told about the superiority of PAL because of its built in color correction and siting the superiority of having no tint control.

I personally think the built in color correction was a very compelling feature of the PAL color encoding system, so I'm not interested in that so much. What I am interested is in the implementation on a PAL set.

I assume that color phase (which is what the tint control is called on a professional monitor) was preset at the factory for PAL sets. That way the PAL set would be calibrated to the correct color phase and need no adjustments in the field (the above touted lack of tint control).

But is there a color phase adjustment pot on the inside of the set? For example, on a circuit card or color decoder board? That way if the set came out of adjustment it could easily be recalibrated?

I guess what I'm asking is did they just move the tint control from the outside of the set where it would be an end user adjustable control, to the inside of the set where only a repair tech would have access to it? Or was the factory calibration good enough where absolutely no adjustments were provided for?

Might be a stupid question, but it was just something I was curious about.
