Help with my Nishijin Y&O Model

Try to see what's stopping them from coming out the back.

When you say it plays. When you drop a ball in the middle start pocket. Do the video reels spin?

Yes, when I first bought it, there was not a jam and if you dropped a ball in the pocket, the reels would spin and music would come on and if there was a payout to be had, it never gave any. But now there is a jam and I think my son took the back off and messed with it.
