If you're sure that you have:
Turned the cabinet above in Hall B to the on position and that it shows the green light at top left of the cabinet is lit.
Also that the lever of the brown control panel is on position.
Double check this part. Usually it is the problem:
Go to storeroom and down to the cellar. Go to the factory circuit left of the hungry monster.
Flip off the left switch of Hall B and flip the switch of lobby using the push skill. Push the lobby lever down.
