Hi all, Have a Panasonic 42PE50B for just over two weeks. After day three I noticed a buzzing coming from the rear of the set (definitely did not have it at first) - sounds like a circuitry/PSU buzz. I accept that all plasmas will buzz to a certain degree, however (here's the question).......should you be able to hear the buzzing from 12ft away (as my wife and I can) during quiet scenes and when on mute? The buzzing is worse during bright scenes and when in dynamic mode. My opinion is definitely not since it really does interfere with my enjoyment of the televison. I can't see how it can be deemed 'fit for purpose' if it makes so much noise. I would really like to hear other peoples opinion as it will hopefully provide extra weight when I go back to retailer and seek a replacement. Thanks in advance.
