so i finally goto to look at my machine, and i noticed that the little floor on my center feature doesnt function correctly. i have pin pointed the part that seems to not be functioning. i believe it is the solinoid (sp?, also i think that is a solinoid, i might be wrong calling it that). I was wondering if there is a way i can test it to see if the part is working, and i have a bad connection, so it is not getting powered. or if the piece is broken. if it is in fact fried, is there any way to replace it, or is that something i just wont find a replacement for? here are some pics. it is the black cylinder with the white sticker. any insight will be appreciated

this video below shows how the floor is supposed to shut

@ 1:13 the floor snaps shut, and allows a second v zone to be accessible, this is how the bonus is continued for another round.
without the floor shutting even if the ball goes in the original v zone, the bonus ends.

if needed i can up a video of my machine. thanks in advance!
