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.

Faint lines show up when i get dark screens in movies


First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.
Thanks.

Dark vertical line(s) on Lcd tv


Most likely it's the LCD panel failure. You can replace the panel if you can find a spare part. But the new panel may cost you as much as to buy a new tv. Hope that will help you.
