Question about LG 42PC5D Television
The TV makes this humming/buzzing sound when it's on. It comes from the left side of the TV (where the front component inputs are). I actually exchanged it last night for another TV (same model). It's the same thing, not as loud though. A tech guy at Best Buy told me that it might be the built-in HDTV tuner, and that I can download an update from the internet and install it into the TV. Anyways, if anyone has some input it would be appreciated.

Have you tried adjusting the contrast? , have a similar problem with a 42'' lcd and it appears to be related to the contrast setting .If is set my contrast below 90% the buzzing sound stops.
This buzzing sound seems to be a common problem with LG TV's

I tried Electcentric's solution of dialing the backlight up to 100 and that worked, unclear if there will be a downside to it, but the buzzing has definitely gone.
