I´ve now had a PV60 (PX60 without dvb-t) for a week, and even though I can hear the fans, they are not disturbing me. But I can hear some kind of buzzing from the sides of the tv - it can be heard clearly when I stand next to the tv, but should not disturb 10 feet away. I guess it´s the power supply. However, I can hear a very high frequency sound, which bothers me (but not anybody else at home) I´ve spoken to the Panasonic repair shop, and they offered to pick it up and treat it with some kind of spray/silicone. In a PV500 thread about buzzing some people mentioned the same as far as I recall. My question is: Has anybody experienced that this kind of treatment has actually helped? I could also get it replaced, but my feeling is that they are all the same (have listened to a couple of sets in the store) I have also considered swapping it to a PA50 (PE50) because perhaps the lower plasma cell count mean that the power-supply doesn´t have to work as hard. It would be a sad decision, because in every other way, this is a fantastic set. What do you think?
