Be VERY careful while discharging the monitor. Most monitors discharge themselves after they have been off for a period of time. Usually a day or two. Follow Chad's advice - Screwdriver with a wire wrapped around it. The other end of the wire connected to the chassis body (metal), and slip the other end under the high tension cable under the section cup. You should hear a "pop". If the monitor is already discharged, you might not hear anything. Then wriggle the suction cup fitting lose and then touch the metal prongs back onto the chassis. You are ready to go now !

If you are unsure, get someone out to do it for you.
