Don't be afraid to discharge, it's super simple and very easy to do safely.
Good vid, not me, and you don't need one of those specialty tools, you need a screwdriver, a wire, and some tape. Tape one exposed end of the wire to the metal of the screwdriver and affix the other to the frame of the set, make sure you aren't touching the set, and slide the screwdriver in until you hit metal. Easy peasy!
