Well last night I was watching my 42 and the buzzing got really loud. It hasn't been this loud yet. It seems to only get loud when there is a bright image on the screen. Darker scenes didn't make it as loud. I had to have the volume up to 20 for it to even begin to muffle the buzz and I sit about 7 feet away. I think I will return the set today to best buy and see what other options are out there. I don't want to try another c450. This sucks because I was just starting to like the picture on this, but the buzzing will be annoying.
I have some questions for those of you who have returned TVs to BB. Do I need to put it back in the box or can I just carry it in the way it is along with the remote and manuals? Also, I bought the 2-year black tie protection, but I don't want to use it. I only had the TV for 4 days. I'm still within the 30 day return period so they should just credit me what I paid toward a different model? Will I have to purchase another 2-year warranty? I hope not. Thanks for any help.
