I have recently purchased the Samsung PN58C7000. On another forum there was a post which talked of high AM radio frequency interference from this same TV, so I decided to do my own experiment.
To my amazement I have found extreme interference not only near the panel, but at 20 meters outside of the house! As soon as the TV is turned off, the noise completely disappears.
Samsung Tech Support have told the original poster to have the TV replaced as it is not acceptable, which he has done but nothing has changed, and everyone who has done the AM radio test on the said forum hears the same interference, Does anyone have any knowledge about this and should we be concerned health wise??
Below I have attached an identical example of what I hear.
