How are video games projected on screen?

Why is my tv picture bigger than my screen?

We have an older tv (Sony KP-43T75 projection tv, 4:3 standard def) in the basement that my younger brother uses for video games. I'm using it to watch a hockey game right now and I am noticing that an inch or two is cut off on all sides. It's like the projector on the inside is projecting the image too large for the screen.

Does anyone have any idea how to possibly fix this? Any help would be greatly appreciated.

Well if it is possible for "YOU" to open the back of the TV and pull the projecter back a tad without harming it, then it should be fixed.
