You need to discharge the high voltage first. Here is my favorite method of doing it: Get a large screwdriver and a wire with alligator clips. Connect one end securely to the metal shaft of the driver and the other end securely to something grounded on the set-there will be some sort of spring that makes contact with the outside of the picture tube and it will have a small wire connected to it, probably running somewhere on the chassis. Hook the other alligator clip to that spring or that wire. There might be a metal frame for that chassis which will work, too. Now, with one arm behind your back, and your hand off the screwdriver shaft, poke the tip of the screwdriver under the "suction cup" HV connector on the picture tube. When you make contact with the connection you should hear a "snap" from the HV discharging. Do it a couple times. Then you can grasp the rubber cup and pull the connector off the tube. Usually you have to squeeze it and wiggle it around some. Before you put it back on there, I would discharge the HV again. They can build up a charge just sitting there.
The HV wouldn't kill you; but you sure wouldn't like the experience!
