Alot of Tv's have this sound that comes from the speakers or the back of the set. Its normally when the transformers inside are underload they start buzzing. this could come from the Powersupply or the Inverter. When changing channels they change their tone sometimes.

    It just depends on how old it is, if its fairly old then it might need some solder joint reflowing as dry joints could be causing the tv to draw more power than the transformer can handle thus making it buzz, in the case of the inverter buzzing the CCFL bulbs that light up the screen could be drawing too much current causing it to buzz.

LG 32LC2DB television says No Signal after 30 min


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

I'm pretty sure that the buzzing sound is a not normal thing for an LCD TV. I sell Flat Panels during my spare time and it should be as quiet as a CRT types. It is more likely a defect and you should return it ASAP.
Hope this helps.
