Jay, you shouldn't have to remount the cartridge if the unit came with the cartridge mounted. And since no one knows what the preoblem actually is, the whole TT is going to have to go back to MH anyway, so let them remount a new cartridge (if that's even the problem.)
This kind of thing sucks, however, when something is in warranty, you just have to take the attitude that you have 'all the time in the world' for it to be made right, even if it means them replacing the entire unit after figuring out they can't fix it!
Another very important tip: keep all records showing (1) the date you returned it to the dealer for repair (NOT the date he sent it to MH, but the date you returned it to HIM -- get a receipt!) and (2) the date you received a working unit back. Attach these to your original purchase invoice. The time elapsed between the two dates can be (legally) added to extend your warranty ;--)
