My samsung TV won't show any picture/sound.

Question

So, I turned my tv off like i normally do on my 32 inch samsung LN32A330J1N lcd tv. And the sound goes off, so I know it turns off.

But I come come, and try to turn the tv on, and nothing.. No noise. I have made sure that it's plugged, in the red light is on, so I know it has power. I have tried using it in different outlets, and even checked if it was the motorola cable box, it's the tv.  Even the on screen guides don't show up.

Any help?
