Machine was on. I was looking at an error on the screen that I think was related to the pallet changer (that isn't on the machine anymore). The control turned off. I think I heard a click but wasn't able to tell if it was from the control or a breaker in the cabinet. I've checked every breaker I can find. I suspect a fuse or breaker that I'm not readily finding. Pressing the power switch doesn't make any clicking noises or turn on the CRT. Any ideas?
