I dont know where it got started either but I'm going to +1 this statement. I've been fixing coin-op arcade games since 1984. I NEVER did anything but discharge tubes with a piece of wire and a screwdriver and not once did the high voltage diode get damaged.
I dont even bother to discharge any of the new monitors. I just pull the cap off and hope I dont get nailed! LOL!

I've tested K7000's, and never seen one that has a charge left in it. By test, I mean pull the damn anode cup off and touch it to the frame, and then touch a screwdriver to the tube as well. No spark. So at least the K7000's I don't believe hold a charge. If they're not working properly, though, it may hold a charge, and certainly other monitors DO hold a charge. K7000's though you don't have to worry about discharging, just grab the anode cup and have at it.
