Is there a way of reducing picture noise on a plasma? I have a PDP 434 and have noticed that (looking from very close up) there is a fair amount of "noise" from all sources except VGA, which still has noise, but much less. Both scart inputs are set to RGB and I dont use the analogue tuner. As the VGA signal is quite clean, I would have expected progresssive component from the DVD to have been clean as well (IIRC VGA is pretty much a component signal anyway). I've shielded the power cable going into the panel but I'm wondering if I should put the rest of the kit on a "clean" mains supply, or if there is something else worth trying? Thanks! PS. I've turned off all the picture processing and set contrast down to about 26 as this gives a much more clear and natural look, and I'm not using HDMI yet.
