Hello,
I totally agree with Igans316. Don´t accept the fault of the Pana Plasma only cause they tell you to do. Perhaps some of the purple issue is indeed source-quality related, there is also clearly a problem to the Panasonic. For myself, I got really purple problems with my 42' until I got a new board with a modified software from Japan last friday (I think, it is the same as Igans316 got last tuesday - I was told it was one of the 3 first boards available here in Germany). Now, most of my snakes are nearly gone and e.g. in the Harry Potter underwater-scene, I got only some little fizzing purple dots. This dots aren´t alright in my opinion, but a big improvement for my situation. So I think, other affected owner should at least try to get the improved boards and let´s hope they can get rid of the purple issue with the infos Igans can give them next tuesday.
