I have just got a Panasonic 32PB50 and I am getting a slight problem with the picture when watching DVD's. I have a Pioneer DV444 connected to AV1 running in RGB mode and when I was watching Lord of the Rings (region2) last night I noticed a discoloured bar appears in the top half of the screen. It goes horzontaly all the way accross and is about 2 inches thick. You cannot see this on dark scenes but on very light scenes it is obvious. It puts a purple hue over the picture in the bar. Does anyone else have this problem or know a fix for it?
