We have an older 27" TV with I believe a "coax" cable in the back (it's the input that you'd hook basic cable to or an old NES system to... you screw cables into it. Anyway, I need to know if there is an adapter out there that allows you to hook up a new system to an old TV... that will take the new system's component cables (the yellow, white, red cables) and adapt it so it can connect to the old TV. Can anyone help?
