Now I don't want to scare you, but this will be releasing an average of 20,000 volts of power from your tube. If you take precautions, everything will be fine. Clip one end to the metal chassis of the monitor, and the other end to the shaft of a very long, thin, plastic or rubber handled screwdriver. Wait 5 minutes or so and do it again. If you don't hear anything the first time, no need to wait and retry.
Many monitors lose their charge on their own.
It's a little frightening the first couple of times, but the thrill wears off. The alligator clips are optional, some recommend that you don't use them in fear that they will fall off during the procedure. You can just wrap the exposed wire around the screwdriver and around the metal chassis. It is clipped to the monitor, you can squeeze and rock it back and forth to get it off of the tube at the suction cup thing. Remember where the cables went and how they are oriented so you'll be able to reconnect them when you put it back together.
