Kind of new to this projector scene, so forgive me if this a very obvious problem! Basically when I first switch on the PJ the picture displayed looks kind of like a green negative, if you see what I mean... It doesn't seem to matter what input I use (I'm not using the PC inputs at all) the problem is the same. When I switch inputs the picture displays fine, then fairly quickly reverts back to the evil green! after 10 - 20 mins it seems to settle down and doesn't do it anymore. Is there some kind of setting I'm missing, is this usual PJ behaviour, or should I be shouting at the supplier and/or Panasonic? Many thanks in advance for the help. P.S. Great forum, glad I stumbled across it!
