Just discharged my first monitor (I feel vigorous!)
I heard a click when I inserted the screw driver, the second time there was no sound at all. This is probably a stupid question, but do the clips inside the anode cap sound similar to the discharge when you're trying to remove them? I'm trying to figure out if the click I heard was actually voltage being discharged or simply the clips moving around.

yes, sometimes they do. some have little pokey bits on them.
people wait and do it several times. I don't. i discharge and at the same time use my screwdriver to flip back the cup inside out and then push one side of the clip out.... in one fluid motion.
what you are actually doing is discharging the tube, not the chassis. the tube is what holds the charge. some tubes tend to "re-generate" their charge...the voltage is deep in the glass. this is especially true of older tubes and large 33" tubes.
if you are still concerned... sometimes i'll clip a wire with an alligator clip at the end to the tubes belly button and the other to the rimband on problem tubes while i fix the chassis. then i don't get another surprise when i go to but it back on.
if you do get zapped it's not so bad... more scary than anything.

I also do what Lilshawn does - discharge, then use the tip to compress the pins. Then remove right away. There's no need to keep discharging.
I do, however, discharge right before I put the clip back ON. As you know, the charge can build back up.

I have NEVER gotten a pop when I have done it, even right after a monitor was powered on recently. And most of the time the discharging with a screwdriver/tool leads to me accidentally popping the anode cap off anyways, so it sounds like an easy way to kill 2 birds with one stone, eh?

most monitors chassis have a bleeder resistor inside the flyback that uses up the last little bit of power inside the tube when shutdown.
if it doesn't have one (or is defective) be prepared. ;D I find allot of the larger 30 inch and up tubes seem to lack this power dissipating feature. (IE Makvision) and with the tubes so big, you can get quite a crack when discharging.
