I had no buzz at all, but when I turned on the tv tonight and the cable box didn't come on, I did hear a little buzz, but with the cable box on and watching a show, I don't hear it. What does everyone use to clean the dust off there screen. I know they give you that little blue rag for the frame, but I wasn't sure about the screen, and the last thing I want to do is scratch it. Ive only had the tv for 2 weeks and just from running the sleeve of my sweatshirt around the frame it looks like there is tiny scratches. I guess with that high gloss finish its almost impossible not to get tiny scratches, just like a cars finish.
