I am experiencing a ghosting effect on the TV (3 weeks old) noticeable on sports programmes as the camera moves across the screen. It is a dark haze in the background. Did not have this problem on my previous Samsung TV. I have a Samsung Soundbar HW-Q800T connected immediately under the TV.
So far I have tried:
Adjusting all picture controls
Reconnecting to different HDMI socket
Disconnnecting Soundbar and moving it away from the TV
Turning off Router and Cable TV.
Plugging the TV in a different socket
None of these have cured the problem and it is constant on both cable and terrestrial programmes.
