Guide :Optics : LXD55 AR5EC Achromatic 5 in f9 Refracting Telescope 05095503

LXD75 AR6-AT I have a problem with the doublet lens. I seem to be able to collimate it, but there is still light that spreads out from stars and planets that are brite. Also when I'm handling the scope to place it on the mount I hear a clunking sound from the objective lens. I think the secondary part of the doublet is loose. I see the concentric rings when I attempt to collimate the scope but the blob of light that forms when you defocus the scope, forms beside the star and not on top (as I would expect). If the corrector lens is loose an slumping down from it's correct tightened spot would this cause the image to spray light from where it's meant to? Can I repair this or should I return the scope to Meade?
