A note about monitor discharging

I think it's the way some people like to describe monitor discharging, or they are passing on the same fear, uncertainty and doubt that was passed onto them. Like when I asked my buddy if he's ever discharged a monitor and he proceeded to tell me about the time that he discharged one that was so powerful that the screwdriver was shot from his hand, flying across the room and impaled itself into the drywall handle deep. Or the story about a friend of his who once saw someone who decided to touch the anode cap of a still-charged monitor, blowing his thumb off completely.
But something tells me that all the parties involved weren't very bright (my friend included). ;D
Ummon:
Sounds like they were illuminated greatly, to me. Alternatively, those sound like big fish stories, too.

People writing advice aren't writing it for others who already know how to discharge. We're writing it for people who don't know, and don't understand, where the teeth are. Common sense is that if you don't know where the teeth are you don't stick your hand in until you do. You know damn well that people don't read instructions, don't take advice, and absolutely don't read whole threads. Given those facts about the people who are usually looking for instructions we write them in harsher language than is necessary. Intelligent and prudent people do not need to be told the monitor is going to kill them. Most people are neither intelligent nor prudent.
BTW, for the people who are talking about TVs and PC monitors... a lot of them are housing ground and not chassis ground. They are not the same as an arcade monitor that is designed to run without a dedicated housing. This is important and some of them are dangerous if you handle them the same way as an arcade monitor. The challenge here is that in order to know which are which you have to already understand what you're doing.

I used to work at an Apple authorized reseller doing repair work. We had one guy who would just grab the anode cap and pull it off the tube with his bare hands on the iMacs and Apple monitors. These more than likely would self-discharge when not powered but his method was to say the least, ballsy.
We of course had the right tool which was a length of 8 gauge wire with a clip on one end and an insulated probe with a solid wire exposed on the other. You ground to the chassis frame, sneak the tip under the anode cup, wait a second, and then remove it. Other places, not so well equipped, we would just use alligator clips and screwdrivers.
We would always store the analog boards with the anode caps secured to the metal chassis frame to ensure the flyback didn't store a charge.
I always hated working on monitors, not for the danger, but because replacing a part wouldn't always fix the problem on the first try and you'd have to tear the WHOLE thing down again.
