One day, the stage lights flickered all at once very slightly, it was hardly noticeable. Over the next 6 months it got worse and worse. The problem was that it was sporadic, and just happened at random. This was the theater at my high school, so we weren't doing a show all of the time, and the lights stay dark most of the year. So when the next show came around, we were in trouble. Eventually the lights flickered (and would nearly go black) when I was by the dimmer rack. I pulled out some modules to look at the CEM (an ETC rack), and then it starting going haywire, the lights on stage would flicker like crazy (someone was shouting this to me), and the rack seemed to turn itself off. Did some research, found out that the problem was the airflow sensor. Called ETC, they sent a part. A little plastic part no bigger than the tip of your thumb to sit over the sensor. Never had the problem again. Luckily we managed to fix it before the next show.
