Hi all Does anyone use the RGB of DVD playback on this set ? If so is the picture OK ? The problem I have is that the picture flickers intermittently It seems to be when the picture content is quite contrasty (ie outdoor scenes) and is as though the RGB circuits cannot handle signals of a larger amplitude. I've tried composite and S-Video and both are fine, however the quality is obviosly not as good. I have an engineer calling to have a look at this fault (among others) with the view to exchanging the set (it's less that 2 weeks old) and I need to be sure that this is a 'one off' and not a stock fault.
