One of my favorite episodes of the Beverly Hillbillies was Jethro sticking
his tongue into the light socket to show Ellie May "What the big old dumb

Sigh. And since my original post was that a child should not take apart
a TV unless a grown-up knows how to discharge the thing that holds the
charge...it is likely we're all in agreement essentially.

That's the LEAST of your worries. Ever seen a picture tube implosion?

Any TV that's been sitting for a week won't have a charge in it.

BULLSHIT! Put your tongue on the HV lead of the flyback transformer six
months after you unplugged it and you'll probably piss all over yourself
if
you are lucky..

I'd do it, I pretty regularly touch flyback HV leads, there's nothing in the
flyback that can store a charge, the tube itself does that. A B&W monitor or
a vacuum tube TV chassis can hold a charge for quite some time, but a solid
state color set has a focus divider that'll discharge the HV within minutes.
It's still always wise to ground the anode just in case though.

Depends mostly on the quality of the rectifier, and on whether there are
any bleeding resistors or voltage dividers. Give a vacuum type HV
rectifier and no bleeding resistors it should be easily possible that a
picture tube retains high voltage for weeks.

Well that's certainly true, though mostly due to the implosion hazard.

You sure don't want to touch the ungrounded coating on a picture tube a
minute after switchoff while standing in a second story window. True story.

Rita?

The HV rectifier is typically a little leaky (especially when hotter)
and will by itself gently bleed off the charge (if 1^12 ohms and 25nF,
this is about 34 hours). But most HV sections have the focus divider
at the output of the rectifier and this will quickly drain the charge,
in under 2 minutes (about 500Meg ohms).

A*s*i*m*o*v

.... Wasted power is current squared times the resistance.

Ah, only now I see your name... I don't know about it's etimology. It
could have something to do with ducks and wood, maybe your ancestors
lived near a ducktrap. I guess that's not too good an explanation...

Here I am with my story again...

We have, most of us, tongue-tested a 9 volt battery, I think. I once,
foolishly, tested a 10.6 VDC, 850 mA cellular telephone charger. Big
mistake... :)

When I was five years old my dad was less than impressed when I took his

My dad was a very good backyard mechanic, but for some reason didn't
get into the more intricate stuff. One sunny summer Saturday morning,
I placed a sheet of plywood on the ground, removed the Carter BBD (I
think) carburator from the 225 slant-six motor in the 1965 Dodge
Polara station wagon he was preparing for the road, and stripped it
down on the sheet of plywood. My dad had worked a backshift, and at
about 1130 or so came outside, and turned white as a sheet. He said,
"Are you sure you can get that thing back together?" I assured him
that I could, and I did, and the car lived to ride again. :)

I still don't understand why a man who could strip down a motor or
transmission, install new rings, valves, etc., had a problem with a
carburator...I couldn't rebuild a motor to save my own life, but I've
rebuilt a number of carburators...strange.

During the first week, out teacher opened up a TV to show us how much power
was still present even though the the set was unplugged. He then proceeded
to show us how to discharge the thing that held the charge. Apparently,
using
a borrowed screwdriver that had a crack in the handle is not the proper way.

With solid state-uP based sets, the proper way involves the slow
draining of the voltage/current anyway...through a high-value
resistor.

One time we were sending a bunch of CRT's back to the manufacturer for
proof-of- replacement one time, and my wife was labelling them. She
was wearing a knitted sweater, and the sleeve brushed against the 2nd
anode. She wasn't pleased with the result. The CRT had been sitting
for weeks to months...

A little word of advice to the technically curious youngsters out there.
NEVER use your mother the beautician's professional diamond coated nail file
to deburr the driveshaft of the lawn mower engine you are rebuilding.

It makes your butt hurt really bad.

The guys used to do that to prove that the ovens weren't really all that

might happen.
