Hello, has anyone else got a 36pg50 (or smaller) and noticed in darkening/dark scenes viewed in a darkened room you can see lines on screen? I have a horizontal (2-3 cm)and vertical (2-3 inch wide) noticeable in dvds. And two vertical lines, which I think are actually outer edges of a central block that is slightly lighter than the outer edges - and it isn't an aspect thing cause they are there regardless of ratio. Plus a central line in all viewing types, particularly in progressive scan. But apart from that in dif lighting/scenes it's great. Let's sob mate! Any known solutions or similar experiences any one? I've wrote to panny but still waiting reply after got an initial 'not known to us', cheers.
