I doubt very much that the problem is the CCD.  Instead, I expect that light
is scattering off dust or oils on the optics.  

One way to check out the scanner would be to take a completely unexposed
piece of slide film (the scraps from the end of  roll would work great) and
use a paper punch to make a clear area in the middle.  If the CCD is the
problem, you should see ghosting in one direction only around the hole.  If
the problem is contamination on the optics the haze should be uniform in all
directions.
