I am seriously considering one of these televisions to replace an original LC-30HV2U. However, one of the reasons I want to get rid of the old one is the noise the cooling fan makes, which at low volumes at night is quite audible. The new panels look great, but it's impossible to judge the fan noise (both in the panel and in the avc unit) in a noisy showroom. I would be very grateful for any impressions of the noise these TVs make in the home environment. Thanks.
