i thought it was bit wierd my self, because i went into 3 sony shops and put my ear to the same lcd but no sound the staff just said its because there noise around the store i was thinking hmmm i dont think so. because at the top of the lcd i hear like i said the buzzing sound sony staff said is the transformer or something but like u said you dont hear it so i think they conning me a little bit, plus when turning the tv I get some noise like crackling but this crackling noise i hear alot when tv is on more often when playing xbox on it, i think it maybe best i pay a visit to store again but sadly a engineer will have to come down first to confirm it faulty then hope i can get exchange you think that will be best?
