Hello,
I recently got an Olympia Joker that has no sound. The previous owner says everything was fine, then one day the sound simply didn't work. All wiring connections appear to be intact. There is a main fuse, and one for the hopper, but there does not appear to be any fuse dedicated audio. I found the volume control on the inside of the door, which was at the highest setting, and changing the setting had no effect. I thought maybe if the control was dirty, moving it around might work, but it did not. I am wondering if the speaker might be blown. How probable is it for this to occur in this type of machine? Are there other common causes for this problem I might be overlooking? It only has one tiny little speaker in it, do these things ever just blow out?
