LN46A650 (user),
Welcome to the forum.
The scrolling bar is an image retention and burn-in feature built into certain models of Samsung plasma units. It wouldn't be available on the LN46A650, as that's an LCD unit.
Let me know if I can assist you further.

Where can I find this feature on my Ln46@650 or do I even have it. I don't see it in the manual?
