Tell me if you think this method is ok. I have a large steel support beam beside my work bench downstairs. I’ve been pulling off the flyback suction attached to the glass and touching inside prongs to the steel beam. I’m hoping this is grounding them but to be safe I’m leaving the main cord attached to the flyback. Thoughts?
the beam might not be grounded.
You can attach a wire from the beam to your copper plumbing and it will be grounded.
I have a flat head screw driver that i soldered a wire to and then cut off all but the grounding plug. I plug this into an outlet that i know is grounded and use that to discharge monitors.
If the tv isn't pluged in then why would the beam be an electrical ground for a tv. You are attempting to discharge a capacitor that is part of a circuit. The circuit is in the tv. connect the wire to the common ground on the tv. Mike.

Now go beat the copper out of something, Miked

But Mike it wants to go to an earth ground or to something with least resistance. The beam might be thru the concrete into the earth then it would make an excellent ground. Just throw a ground stake in the ground outside your window and bring in a wire from it with a small alligator style clamp on it and clamp it to the metal chassis of the TV, Use copper wire for least resistance.

Better to use the beam versus your tater tots as a ground.
If you use a chassis as the ground then the potenial(voltage) will go to zero the beam may work as well. The theory side of me comes out sometimes, Mike.

Would that make them "baked tater tots"??? Or fried,,,Better to use the beam versus your tater tots as a ground.

No it wants an "earth ground".ok seriously theres a pipe laying loose on the garage floor will that work

I never really had a problem with monitors/tvs but every dam time I get out of the wife's car and hit the lock button I get zotted, so now I touch the button with the key first.

If the CRT has been unplugged for a week or more, the capacitor should have lost its charge. But I always check anyway just to be safe. I had a TV the other day where I could not find a ground on it. I don't know if this is true, but supposedly you can use the aquadag as a ground. I did not make that word up.
Most likely the beam should be grounded; you can use a continuity tester from building ground to the beam to check. If you use the beam, make sure you are connected to the steel by scratching off a bit of the rust-inhibitor coating.
The copper water pipe would be a better ground though. That's the way I would go if it was close enough to the work place.

That beam is most likely not grounded unless for some reason they used it as a run for some copper pipe. Typically the steel beam will sit in a pocket that is formed up when they pour the foundation. It is seperated from the earth by a few inches of concrete. like drozenski said u should use a water line as your ground. If there isnt any close to your bench you could just ground the beam itself to the water line.

Don't know why as their only a 3 volt battery.Originally Posted by KZBell

It's the lock button on the door of the car and I think it's static electricity that is the culprit...very dry air in Denver.

Might need to check out one of these, like the oil/gas trucks have on them.

At the opposite end of the suction cup... what is that?? Some sort of transformer? Is it worth keeping them if you have alot? I've just been setting them aside for now. I dont feel like trying to call and ask the yard about those lol.

Flyback transformer. That's what steps up the voltage to the ridiculously high amount you see in the tube.
In electronics class we just discharged the tubes right to the tv's ground strap. Heard the crackle a few times doing this. I will agree with the other members hear also, a good earth ground will also probably do the trick.

Couldn't agree more I prefer my tots not fried
I would like to reask NDs question about the flyback transformers value. Anything more valuable it than just keeeping it on the low grade? I tried breaking one apart without much success. Seemed to be mostly that hard plastic. Don't think it would be worth the effort if there was though, unless there is an easy way to hack at it.

I agree 100%, but make sure your also discharging the cap's. And the transformer I just throw it in with the computer fans and other small transformers I pull off boards.

If you're getting much over shred price for your low grade---say, .15 or above, keep it on the low grade board. Many yards will pay EM prices for them but since I get +.20 for my low grades I keep them on. In fact, I dont pull anything off unless its very easy to get to. Just not worth the time.
