Can you copy and paste the relevant part? That site requires an accout to view.

I think he's talking about this:
"If you're just pulling the monitor to swap it out, you should *not* discharge the tube. You should only do that when you're going to work on the unit."
Any comments?? I've removed my K7000 series 25" many times without discharging. Here's the comments I left:
"There's a couple things that dictate discharge vs no discharge.
- Most 90's monitors and newer have circuitary that automatically discharge the monitor once they power down.
- If all you're doing is moving the monitor from one cab to another, I don't see why you'd need to discharge the unit. All you're doing is touching the chasis and the front of the tube. It's not like you're sticking your fingers under the anode (where most of the charge is located!)
So discharging it for movement I think is more dangerous than not. "

If the entire unit is coming out I think it would more trouble than its worth to discharge. But I'm not ken, so am I allowed to comment? :P

I could not get into that site either. It asked for login and password.
Absolutely NO NEED to discharge a monitor just to either take out, put in, or swap it. You only need to discharge it if you're going to work on it like pulling out the main board to recap it or replace a component.
Be aware though that if you're going to remove a monitor and that monitor was _just_ turned off and there is no ground strap/wire connected to the frame then there's a good possibility of a static charge on the front glass. So if you tip the monitor face towards you you may get a static zap just like you'd get if walking across a carpet and touching a doorknob. This sudden (and maybe unexpected) static zap may startle you enough to make you drop or jerk the monitor causing damage to you, the monitor, or both. For safety be sure the monitor has been off/unplugged at least ten minutes and that there was a ground strap connected to the frame.
Some newer monitors do have circuitry that disharge the high voltage right after power off, but remember that as a safety precaution (and to stay alive!) assume that the monitor is fully charged.

Grrr....
I've posted NUMEROUS times that I have no idea how the idea started on the net that you have to discharge a tube anytime you come near the monitor!!
