Any ideas for fixing a "buzzing noise" on a Panasonic TH-42PZ700U? It occurs on...
...every input, tv, dvd, cable. I just bought this tv and am pretty sure I have everything hooked up right, but am still getting this loud, annoying, buzzing sound. The sound is too loud to be an internal fan in my opinion. It comes and goes when watching hd, standard def, dvd..etc., sometimes it will just stay on, but I have noticed it seems to stop and start when I change channels on the cable box or when there is a scene change in a tv show. So I'm thinking it might be some sort of signal noise?? I don't think it's normal. Using component cables from hd/dvr box from comcast to tv and have checked a million times on the connections. Any suggestions would be appreciated...Thank You.
