connecting laptop to tv

[avfc45]

I am sorry if this question has already been answered.

I have recently brought a new tv that will allow me to connect my laptop to it. I have tried using a VGA cable which gave me picture but no sound. And I have also tried using RCA cables (Ble, red and green ones) which has not given me sound or picture?

can anyone help?

thanks in advance

Does your tv have a aux jack like most modern stereo's do? It looks like a headphone jack, I know mine does and I bought a cord that has the head phone jack on both sides and hook one into the headphone jack in my laptop and then the aux plug on my tv.

i think it does have a head phone jack when when i connect the wire into it and the head phone jack on my computer no sound comes out of either...........
