A Question about PAL television sets

[ppppenguin]

There is no tint or hue control in a PAL set. Internal preset or otherwise*. If the demodulator phase is wrong, the colour simply desaturates slightly. In older decoders there would be presets for the U and V demodulator phase. Various ways to set these but disabling the PAL correction and tuning for minimum "venetian blinds" or "Hanover bars" was one possibility. If these controls are wrongly set the result is reduced tolerance of phase errors, reduced saturation and possibly very slight colour imbalance.


*This is not strictly correct The Thorn 2000 chassis had an unnecessary tint control that varied the R-Y vs B-Y gain. A gimmick and best removed. The early Sony PAL sets had an NTSC style hue control because they didn't have a proper PAL decoder. This is because of patent restrictions.
