I think I broke the game

[slomoe]

I made it down to the kennels, turned right and got to the room with the electronic light switch. When I first turned it on, I heard this switching going on. I left the room but didn't get as far as the other side where the lights are supposed to be cycling.

I came back to the switch and pressed it rapidly a bunch of times. Now, I've learned that the switching noise is the lights in the other hallway turning on and off. The problem is, now the switching has stopped when the display is lit up. But, when I turn off the display, the switching noise returns.

If I turn off the display and leave the room, that hallway is now dark and I get attacked if I go that way. If I turn the display on and go to the other hallway, it is dark and no lights ever come on.

Did I make a bad mistake, or is there something I've overlooked? Any help would be appreciated. Thanks.
