I just bought a new TV and now my Wiimote has a delay for its action

So I just bought a new LCD tv that I thought would be better than my old CRT. however, I've noticed a significant delay between when I press a button during gameplay (Black Ops) and whe the action actuall takes place on screen.

It is most notable during gameplay. I have it plugged in through the component cables.

It is a Sanyo 39" LCD. What's going on and how do I fix it?

EDIT

I just noticed that some tvs have a game mode. I'm unable to find that on this tv. Also, I've read that turning off up scaling might help.
