How to fix "dead" line of pixels on canon dslr camera?

I turned on my canon dslr to find that there was a vertical white line of "dead" pixels on my screen. it does not effect the pictures themself but its a little annoying to have a white line of nothing now the screen. the camera is a rebel xs that i bought about 2 years ago. if anyone knows what to do, how to fix it or who to go to that would be much appreciated. thanks
