New to these machines, need help please.

Greetings all,

I recently got this machine, and all was working fine until the other day. I turned it on, launched a ball, and it went in one of the holes. Now it won't do anything except a continuing cycle over and over. I turned it off, emptied all balls, turned it back and nothing changes. I put some balls back into the back top tray, and nothing changed. It won't launch a ball any longer either, however I hear the mechanism working as it before. Now it just lights up, and cycles through the same routine over and over.

I actually don't even know what I have here except it is a Heiwa. I have attached pictures if that helps any.

Any assistance would be appreciated.
