I read (and reread) numerous posts on this and other sights and decided
I was ready to give it a try. I have a Donkey Kong that I want to
replace the monitor on. The game has been unplugged for a few days. I
used a screwdriver with lamp cord attached to the frame as described in
the other posts. When I slip the screwdriver under the rubber I got no
snap crackle or pop! How do I know if the monitor is truly discharged?
I really do not want to give my wife the pleasure of burying me just
yet! LOL

Always best to be cautious! Personally I would wait a few minutes
after my initial attempt and try again. Under the suction cup thing
there are a couple of metal prongs that you need to make contact with
in order to make sure the monitor is being discharged (if you didn't
already know that) I know some people can use the end of the
screwdriver to actually remove the clips from the tube, which probably
makes things a little safer. It certainly doesn't hurt that you left
the monitor sit for a few days, that could be why you didn't hear a
pop. Are you replacing the whole monitor or just doing a tube swap?
Although this has been a topic of much debate, you probably won't make
your wife a widow even if something goes wrong, but it sure doesn't
feel good to get "bit" by one of those things!

I am replacing the whole thing with a working setup from another game.
Is it safe to pull the rubber boot off by hand? I have a pair of heavy
duty insulated gloves that I have been wearing.

Most raster monitors slowly bleed off HV by themselves over time. Some
vector monitors do not.

Provided you hooked up your cobbled together discharger correctly, it
should be discharged.

If you are not sure, power the game (and monitor) up, then turn it off &
unplug. Now attempt a discharge, you should hear a snap, wait a minute
or two and discharge again, you may hear a couple of small crackles or
nothing. Monitor should be discharged.

I strongly recommend purchasing an HV probe (w/ integrated meter). eBay
has them cheap, $20 or so. It is a great tool for monitor diagnostics
and discharging.

I've discharged a few monitors in my day, and only once gotten one to pop.
After a few days, most monitors are designed to loose enough charge not to
be so harmful. I would still be cautious though, and definitely remove the
suction cup with the same screwdriver if you can. The day you loose respect
for your good friend electricity, is the day it looses respect for you......

You're probably right, but I always say it's better to be safe than
sorry. Never know when you're pulling that thing out what you might
accidentally grab! I figure you might as well do it, since it only
takes a few seconds to do.

Discharging is easy. I used to be jumpy about the idea, but I've done
it so much that now it's a piece of cake. See here:

If you discharge your monitor immediately after it's been on, you'll
hear almost definitely hear a pop. If you wait a minute and do it
again, you might hear a small crackle.

If the monitor has been off for a while, you likely won't hear anything
at all. Don't worry, it's still likely discharged.

Ater you discharge the monitor continue with the flat blade screw
driver and push the spring metal in and lift the rubber cap up and pull
it off.

Why are you even trying to discharge an old dead if you're replacing the
whole monitor? There's no point in doing that.

I have gotten hit off a monitor that was not used in 3 months. They can
hold there charge for a very long time. Always discharge them before
disconecting the high voltage lead. Ted
