Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

SOURCE: LG LCD TV - Buzzing Sound and Faint Horizontal Lines

From your description, the sound you are hearing is the inverter(s) that drive the back light for the LCD screen/module.
The inverters mounted on the back side (one lower right and one left side) of the LCD screen/module. They are under the sheet metal cover/shields.
The inverters are going out and or the LCD screen/module is going bad too.
That LG TV has only a 1 year on parts and labor from the date of purchase, but you could call LG and ask for their help for such a new TV. They might do it under a warranty, for little or no cost to you.
I hope this information has helped you.
Good Luck.

I have a Nexxtech tv mount, model 8008654 that i used for a 40 inch flat tv. I purchased a 47 inch tv and i want to install it, but i lost the booklet and i'm wondering how to fit the panel


Don't fit the 40" panel for a 47" TV. It's not designed for it.

Buy a mount for a 47" or even a 50" TV instead. It will come with better fixings so that your 47" TV doesn't end up on the floor.

Lg 47 inch tv sound


We had the same problem of pathetic sound quality and volume with a sony brava. Thats just the way they make tv's these days because most people buy a surround sound system as well. We bought logitec computer surround sound speakers for about $140 and plugged into the ear jack, problem solved, we have heaps of volume and stacks of bass.
