So I just bought my boyfriend a Toshiba Satellite L500 series and it runs Windows 7. I'm an IT specialist major and am still stumped as how to do this. We have a VGA cord connected from the laptop to RCA cords which are then connected to the TV. All those cords are plugged in correctly but we are having problems connecting the laptop to the TV. I went to the control panel to preferences to Display settings and tried every setting that there is. But we still can't get any picture or sound on the TV. Please help!!

Thanks!
just tried the windows key + p

that doesn't work either!
