active control on philips 329986

Hi Chris,

The AC combines inputs from all sorts of sensors around the screen and in the mysterious depths of the circuitry. Some of these sensors detect sound levels, some detect signal inputs looking for particularly high luminecence and chroma spikes. Others detect fast movement and others ambient room light levels! (..and people wonder why the Philips is one of the more expensive sets!)

Set on Max and this contraption takes complete control of all sorts of functions. Look at the on screen graphic which shows all this activity and watch all the parameters that are controlled. Problem is, with all this trickery going on two things happen:
1) The picture response (not Pixel Response) slows down causing synch problems and Haloing.
2) It ruins all the fine tuning that has resulted in us acheive the best picture possible.

Run it at Minimum or Off.
