monitor discharge

[G1zm0]

posting this on behalf of a m8, after a monitor/tv has been unpluged, how long does it take to totaly discharge itself without help?

[SirPeale]

Depends on the unit.  It may take seconds.  Or years.  Or it may not happen at all.

That's why people discharge their own.  It's easy.

yeah don't count on that method for your sake and well being.

and don't forget, even after being discharged the monitor might "build up" a new charge after an amount of time, even if it is unplugged!

Remember, a CRT behaves like a large capacitor when not in use. It holds a charge, for a variable amount of time.

If there is no leakage, nothing to discharge it, then theoretically it could hold a charge forever.

I doubt that is the case, but an old TV repairman told me once he had seen television sets that had been sitting for several years and still sparked pretty good when he went to work on them

have serviced tv's for many years . i WILL vouch for that ! if no bleeder resistor present,  a crt can/will hold a charge for long periods.
remember, a capacitor is simply 2 conductors seperated by an insulator .
the conductive coating on both sides of crt glass ( not on the screen and neck - DUH )  becomes the cap
a small value cap ( called a gimmik ) can be made by twisting 2 insulated wires together ( NO conductive connection  !! ) the max voltage would be the insulation breakdown voltage of the wire used .
