Problem with Celestron Starseeker 100mm refractor

I've tried researching this problem with no success, and the folks at Celestron point me to Orion, and Orion points me to user groups.

I have a 100mm Celestron Starseeker refractor. I got it on ebay for a
good price. The original owner said it was gently used, but he wasn't
into it so he sold it. But now I'm figuring out why I got it for a
good price... Well, I struggled a bit on my own trying to get it to align. I
figured I was just dumb and couldn't figure it out. This is my first
computerized/motorized scope. So I went to a local star party this
past weekend where I asked for help from a guy with a similar goto
type telescope.

He confirmed that I have a problem. The problem is that the scope
moves fine when using the direction arrows to generally align a star
in the finder scope. But when you accept that part and then go to
align the star in the eyepiece, the scope lags behind 20-30 seconds
before it starts to move. So I guess it's the fine tuning movement
that doesn't respond correctly. Even if I "successfully" get the
scope to align, if I ask it to go to a chosen database item it doesn't
get it right.

Anyone else have this problem? Anyone know a fix? Will Celestron
repair or replace it? It's past warranty, so I'm on my own. Thank you.

Mike.
