How do I hook up a Wii to a mitsubishi tv?

I have a Mitsubishi 65" Home Theater tv (Model: 65738) and the menu's on the tv suck. I'm having trouble hooking up a Wii to it. Any tips?|||If it has the 3 color ports, plug them in. I have a Sony TV, not sure if its the same but its worth a shot. Ok now use the TV's settings *NOT YOUR CABLE BOX* open the menu for external output. You then select a different mode which is what I do if I want to switch from the game, DVD player or to cable.|||put the cables into the back of the tv where audio and video in diagonally. There will be a red white and yellow inputs. Put the red white and yellow av cables into them by matching them up by color.
