newbie monitor handling
« on: December 28, 2008, 06:04:17 pm »
I need to remove a 25" monitor from the cab while i restore it, I guess this is perfectly safe as long as i dont touch the exposed circuit board or the flyloop?

Im simply lifting it out of the cabinet and putting into storage.

NO!!! NOT SAFE!!! STOP RIGHT NOW!
that ---steaming pile of meadow muffin--- hurts. you can get ZAPPED right in the chest. Been there. hurt like hell.
see the suction cup?
lift it up (just a section of it.)
see the 2 wires?
get a large screwdriver. (flat tip)
tape a wire to the metal of the screwdriver and tape other end to frame of tube
DO Not Have Tube Plugged In to AC Current
touch screwdriver (Flat tip) to two wires under suction cup
I hope you hear a loud POP ( dont  allways happen)
if you do not hear the POP then rub tip back and forth to be safe on the two wires
Make sure the screw driver is making good contact to the metal frame of TUBE
now it is safe

maybe I should not have used caps.
but I wanted to get my point across very firmly.
I have been zapped twice in my life
1st time
I worked at Aladdin's castle. I reached in the coin door and I grabbed the yoke of the tube.

2nd time
I was working on a TV at home.
I discharged it. I left for a bit
some one plugged the set in and then unplugged it. (checking if I got the set fixed yet)
I picked up the TV and got zapped in the chest.
That one took me to my knees.

Yes, caution should be used in handling a monitor, but I almost never discharge them until I get them out of the cabinet. For my part, I find it safer to do when I can get at the second anode (the "suction cup") cleanly.  Having said that, I always discharge, even if I am just putting the monitor aside.

I STRONGLY DISAGREE that you should lift the anode cap to check things out prior to discharge -- to my mind that is far more dangerous than removing the monitor without discharging.

I mean, really, why would you want to put your exposed fingers close the one part of the monitor that is dangerous while powered down ?  :dizzy:

Discharging is not a big deal, although it can seem pretty scary until you do it a couple of times. I have never had a loud pop and often get no pop at all (so I repeat the process a couple of times, just to be sure).

There is a video in this thread that is pretty good.

Obvious rules like making sure there is no power to the cab, not licking the anode cap and making certain that nobody can plug in the monitor while you are away from it  ;) apply. Also make sure that you can handle the monitor and get it to where you want without dropping it -- imploding (then exploding) tubes suck!

Working: Not Enough
Projects: Too Many
Progress: None

I concur
I followed those vids and felt very comfortable discharging then handling the monitor
