If you're going to repair television sets, you're going to have to learn how to discharge a picture tube. It's not hard, nor is it dangerous. And if you do get zapped, remember, it's low current. It'll hurt like hell, but it won't kill you.
Just ground a screwdriver with a cliplead, and slide it under the suction cup. You'll hear a loud ZAP! Do it again, just to be sure. The suction cup is held to the tube with two little metal tabs that go into the hole in the side of the tube. It's a lot like how the top is held on Christmas ornaments. Squeeze the tabs together and rock them out of the hole. I typically have a "discharge tool" handy. It's just a screwdriver with a length of lamp cord connected to it, and the shaft wrapped in tape. The end of the lamp cord has an aligator clip on it. And yes, I've been bitten. By a computer terminal that I _thought_ wasn't producing any high voltage. It was. It hurt, made my arm twitch pretty good, and I felt it afterwards for a good hour or so. But, I'm not dead. And now I'm more careful  -Ian
