Quoted from VALIS666:
My god this video was a lifesaver, and cheers to my wife for finding it while I was in the gameroom cursing up a storm trying to figure out how to simply change out a broken upper slingshot rubber without taking Munchkinland off entirely. I'm sure this is elsewhere in this thread, but just putting it here in case a new WOZ owner (or someone who hasn't had to change the upper slingshot rubber before) runs into this issue.
But of course, every time the playfield goes up/out, it's a 50/50 chance the voice part of the audio gets knocked out, and it did again. Tried to crimp the white RCA plug to fit tighter on the sleeve, didn't fix it. Who knows. My Jersey Jack luck has been terrible this week. Multiple failing mechs on a brand new August built Wonka, this rubber on WOZ breaks in the middle of a game and at first looked like an hours-long project just to change it, I fix that but then the voice audio dies, I'm afraid to turn my Hobbit on lest it go up in flames. And not those really cool game over flames, either.
Maybe just replace the audio cables if they are flakey, I did.
