OK! Sorry to bore you guys! My 36" Strata is back from the engineers. All problems seem to be sorted! picture is fantastic, Apparently was out of focus and the geometry was out. So . . . picture for DVD rules! and progressive scan NTSC mmmm!!!! but . . . My av speakers still buzz through the tweeters when the TV is switched on! The engineer could find nothing wrong! Help what can I do - is very annoying! is like having a lightsabre in the room! HELP! Cheers, Steve.
