I have now taken delivery of PX11 and i'm about 72hrs into running in on low settings. I've noticed that the faces of people have a green-ish tint. What adjustments should I use to get rid of this effect? Also i've followed members advice about using AV2 for audio out into my surround amp. That works, but the sound seems to mainly come from the centre speaker and virtually none from L/R. Does anyone know if there is a setting on the service menu to alter the sound channels?
