2407 Component video input is shifted to left

I use the component video input for my Xbox 360 and it was working fine for years.  Then a couple days ago the picture comes up shifted to the left.  Meaning a bit of the left side is cut off and there is black space to the right.  I looked through the menus for any picture adjustment settings but they do not exist for component input.  Other than the horizontal shift in picture there appears to be nothing else wrong with the picture.  I tried another device with components and it does the same thing.  The VGA and DVI inputs don't have any problems with the picture though, it's only the component input.  Is there anything I can do to adjust this or is it just a defect?
