I've had this tv for a week and noticed an effect which I can only describe as a halo or shadow effect around objects. This effect is more obvious when displaying graphics, Sky's blue banner at the bottom of the screen for example. I've tried it different modes, DRC off, DRC50, DRC100, DNR off, etc and just cant get rid of it. I can reduce the effect to some extent by reducing the sharpness to 0, but that less then ideal. What's really puzzling me is that I cant see this effect when viewing the tv's own menu graphics. Is this the 'smear' effect that some people have been experiencing on other Sony models or is it a 100Hz effect? Could this be a delay line problem (where the colour information is displaced from the b/w information)? If so, does any one know how to make this adjustment from the service menu for this model? Any one ?
