My classroom projector screen will not retract all the way without considerable effort, how can I fix it?

humorous to my students, aggravating to me...

With several attempts, I can assist the retraction spring by lifting the screen into the storage part and have it rolled up enough that I can rest the handle and... bar, for lack of a better term, on top of a bulletin board.  Is there an easy fix or should I just start looking for funds for a new screen?

In general these roller screens ar tensioned by turning one end cap. It will/should pull out slightly and then you can turn it to tension the blind.

your mechanism may be different so take the time to investigate.
