Question about Hitachi 42EDT41 42 in. HD-Ready Plasma Television
Mine has the buzzing. I even created this current one out of 2 damaged ones, the original internals did it as do the internals I took out the "new" one I got (it had a smashed screen). I noticed it stops completely when muted, but not when the volume is on 0. It also gets louder when the contrast is higher (just flick between the preset PICTURE MODE's). I think it's something to do with the internal speaker cables perhaps running too close to the display circuit or whatever (Im not sure what causes it, its normally electrical interferance being picked up by an unshielded cable). I'll no doubt get hacked off and reopen it soon to look about. I'll post back when I do, may be a few months though!
