Forum:Controller sensitivity changed on me

I recently bought a sharp 70" led 3d tv and as soon as I started to play mw3 the sensitivity of my controller has changed for the worst. It very over sensitive when I'm moving or aiming and I haven't changed anything from when I was playing on my old dlp tv. I have tried calling ps and sharp and none have been able to help me. I have changed the sensitivity up and down and still can't get it back to where it was prior to my new tv. I also have reset my controller and the ps3 as well nothing has worked. Anyone help anyone could give me would be great. I'm at the point where I'm going to stop playing because nothing works.
