Where's the ground on a computer monitor? Answered

I'm building a lifter. I'm using an old monitor for a power source. I'm hooking a wire from the 25kV output (that plugs into the monitor tube) but I want to know where the best place is on my monitor board to hook up the ground wire. There seems to be a number of grounds on the board, but I want to be certain; I don't want to smack up the monitor if it can be avoided. Thanks in advance.



Neither. You should build a new ground, using something capable of accepting that kind of discharge.

Let me try to understand this. On my (future) lifter, I will run a wire from the 25kV terminal that plugs into my monitor screen. That wire will wrap around the top of the lifter supplying the power to ions the air around it. Below that, and not in contact with it, is the aluminum sides with a ground wire attached to one leg. That ground wire can be attached to something outside of the monitor, say a 10k ohm/2 watt resistor embedded in a block of rubber?

Sorry, I can't really visualize what you're doing... in fact I fear the worst. I'm just telling you that you should make CERTAIN that you have a ground wire capable of readily discharging the voltages you're dealing with. Connect this to the nearest available contact point and the other end of the wire should be connected to to any good clear path to the ground. I'd go so far as to suggest using a range-outlet's ground-pin. However, why the resistor??? I was under the impression that you need a special kind of resistor to reduce ground current safely.

Sorry...I meant to say "........supplying power to ionize the air around it.

Uhm... If you have to ask, you REALLY shouldn't be attempting this solo. (Or possibly at all; I have no idea what the "lifter" is you're trying to build.)
