|Does your tv have a hdmi, svideo or vga port?|
Normally you have no "converter" box. You take a regular vga cable and connect from the pc vga port to the vga port on the tv.
You would then connect a audio cable from pc to tv for sound.
If the tv has a svga port and so does your video card you would use a svga cable to connect the two.
The last step is to set your tv to the correct interface whether its Video, HDMI, or SVGA
Since you have a converter box you would hookup like this diagram and choose vga on the TV
