Where do plug in the cables for sound from laptop using RCA on a LG LCD TV? - red and white male in jack

Hello, I know that the title seems a little confused, I struggled to think up.

Ok well I have a new Lenovo laptop and want films that are in my LG LCD TV have to be proved. I went to get a VGA cable, works well, the picture is perfect. So now I have an opportunity to the sound from the laptop to get to the TV. I went back and took such a product:

It is a 3.5mm stereo plug to two RCA Y-cable. So I reached 3.5 on the laptop, which corresponds perfectly to the headphone jack. Then I went to the red and white jacks on the back of the TV to connect to. Well, here's the thing. I do not know where infected, I've tried everything that I have made are in red and white. Another person said to be connected,the red and white, right next to the VGA port. But to my LG TV person next to him.

Please help?

Thank you have a quick response.
