How do I discharge a monitor with no frame?
« on: March 18, 2005, 03:32:17 pm »
All the info. I've seen about discharging the tube says to hook the wire to the screwdriver, and the other end to the monitor's frame.  Suppose your monitor doesn't have a frame, or that the frame is made of wood.  What then?  I would guess that hooking up to earth ground via the wall socket would be an option, but I read something recently that said specifically not to do this.  What's the solution?

To  a metal pipe in your house, that'd work.

I hope you were posting in jest there Peale!

Think of a picture tube as a large capacitor.

No, I wasn't joking...I was speaking in ignorance. Thanks for correcting me!

That makes sense, thx Guru!  Is the ground wire (on the tube) usually connected to the monitor's frame?  Is that why most tutorials suggest hooking up to the frame?

I usually clip my dischage lead to the chassis of the monitor and discharge it that way. The chassis should be tied to the tube with a ground wire. I've never had a problem doing this way, just make sure you wait a few minutes and discharge it again to eliminate any residual charge before you pop off the anode lead.

Grau,

when you say "chassis" of the monitor are you referring to the circuit board or the metal mounting frame?

I'm talking about the circuit board. There is usualy a good place to clip your lead too somewhere on there. Usually the metal frame that serves as a heat sink is good. There should be a ground wire that ties the tube to the chassis via the neckboard so the tube is properly grounded and will discharge.

monitors scare me, I just have no clue or confidence that I would actually have discharged it so I would never fully feel good about working with one, and therefore I probably never will.

However, that being said... I just bought two non-working cabinets today with monitors in 'em.  Is it relatively easy/safe to remove a monitor without discharging it first?  And how serious would it actually be to get zapped by a monitor?  Any helpful hints would be greatly appreciated.

Everything I've read says it's simple to remove the monitor and there is no need to discharge it unless you're going to attempt to work on it.  Just be careful not to touch the anode wire (the one attached to the tube with a suction cup) or any of the capacitors on the circuit board.
