I just got my 50" panasonic g-20 set up and I am getting a buzzing noise from 8'+ with low volumes, that is more pronounced when the screen displays large amounts of white. I have read on other forums that people are having similar issues, trying to decide whether I should live with it or return/ excahange. I currently have a 40" samsung lcd that is 4+ years old and no buzz whatsoever. Any thoughts on this, I purchased it at Sears so I believe I have 30 days to return it for exchange/ refund.
