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.
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

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
