Maybe there is something wrong with the graphics processor on your XBOX360 or your TV. Have you tried using the XBOX360 on another TV to see if there are still jaggies?

This is kind of a hard to diagnosis because there are many factors that could be contributing to the problem. So the best thing to do is to narrow the problem down as much as possible. The first thing to do is figure out if it is the TV or the XBOX360 that has the problem (or if there is really a problem at all).

By the way, with consumer electronics it is almost always better to just replace the broken device then to try to repair it yourself. The only reason I ever do repairs on my stuff is because I am an electrical engineer and it presents a fun challenge to me.
