I got a 19"Phillips Magnavox tv with no jacks out put I want to hook a game to it

Can you please make this clearer? The model of TV would help, as would a link to the manual. Same for your PC.

I'm not sure what you mean by a tv with no jacks out. You would need an input jack on the TV that matches an output on your PC, yes? Or are you gaming on something other than a PC - some sort of console?

If we know the two devices, we can look up inputs and outputs and see if there's a matching combination.
