I have had my pv500 for about a week now and have noticed that sometimes when I power up my xbox console it returns me back to terrestial television, not always but 50% of the time. My xbox is softmodded and I wonder if its something to do with the xbox switching from pal > ntsc and during this switch the tv picks up a dropped signal momentarily. Does this make sense? I never noticed this on my old Toshiba crt. Perhaps the lead has become damaged but I can't see really how this could have happened. I have tried AV1 & AV4 connection inputs with no success. I suppose it not the end of the world but can be annoying when I have to keep switching back all the time. Has anyone else experienced this with this tv? Any help much appreciated. Other than this I think the tv is excellent. My first plasma and I am very happy with it.
