I'll try to keep this as "family appropriate" as possible...

Not sure if that would work? The plug isn't live.

There is a couple of good idea's as far as discharging the tv's further up in this thread. Make or buy a ground strap, or use a screwdriver or insulated sidecutters and discharge the bigger capacitors one at a time. The big ones are what stores the dangerous levels of juice. Keep in mind that there is bleed-off resistors built in that are supposed to safely remove the voltage but it sometimes takes a while to accomplish. Hope this helps,,, Mike

Somer great information here, thanks to all of you.

Couldn't you just wear a rubber suit and tie? ....or set the tail up and shoot it with a BB gun, or similar? .... I've never had this happen.

The first things I snip are any wires connecting the tube to the circuit board, then go from there...I always cut out all the wire before anything, though.

It's not the volts that kills you it is the AMPs.

Yeah you can get a scary shock but there is not enough amps to do any serious damage hence the reason people survive lightning strikes or tazers... Unless of course you ground it with your "junk" LOL or leave it plugged in while tearing it apart.

Don't be scared to tear them apart. Just keep your "goods" away from em and you'll be fine.

wrist straps ? G straps ? shocks ? all sounds a little kinky to me. interesting . : ) sry couldnt pass it up.

OH MY,, And we're not in Kansas anymore. LOL

Omg! This subject isn't funny in the least but this post made my sides hurt laughing. I hope this thread doesn't jinx me so far I've never had this happen. I never knew they were still ''live'' when unplugged.

Make a small ground strap with clamps and clamp one end to the screwdriver and the other end to something metal. Being I'm still an electronic tech, I know first hand about burns like that, if they don't kill you, they'll burn you down to the bone and you won't even know it for awhile. I'm just glad your still with us,,, Mike

Hi,

I'm trying to learn how to strip these properly, I usually good with my hands so that isnt the problem. I'm slighly worried about the AMPS, these TV hold. Does anyone know where i can find some pictures of a guide on how to earth the TV?
I can read, but i normally find it easier to look at pictures to know exactly what i'm doing, lol

thanks
Andrew

Why reinvent the wheel? Look what I found! I have done this in class while repairing tvs... a looong time ago. I haven't taken a computer monitor apart for a while. I forget... do they have a suction cup on the glass also?

http://forum.arcadeotaku.com/viewtopic.php?f=4&t=1072

I don't know why the author used a probe. I would just get a double sided alligator clip cord.

Clip one end to the metal parts inside the monitor... the chassis or braided ribbon cable. I don't agree with clipping it on the truck... there will be no way to close the circuit clipping it on the truck. You have to close the circuit by grounding it to something inside the monitor.

Be careful with these. I don't know if the shock will kill you, but falling into your rebar pile, tools or concrete will.

5 years of electronics training and this is all I remember...

That... and hooking up a capacitor backwards will make it go off like a firecracker. The class clown was in my electronics class wanted to be funny. He grabbed a Cap from the parts bin, hooked it up backwards to a bench power supply and cranked it up. BANG, smoke, little pieces of capacitor everywhere. Instructor knew who did it, it was the only one of us white as a ghost and shaking a little bit.

Thanks for the laugh and keeping it family friendly. Glad you are ok.

I was wondering if it would work to install a wall socket in my shop that isn't actually connected to an electrical box? The socket would have wires that were grounded to something like a metal pole, or whatever. It would be easy to just "plug in" an electronic device and let any stored electricity discharge. Would something like that work?

Scrapside actually had a really good idea, that I have seen used before in TV repair shops. You could put up a wall box and ground it to a 4 foot ground rod outside the shop where you tear down "stuff". You could use a plug in BUT so as not to confuse it with an electric plug in I would use a 1/4" mono plug in and install the female into the wall box. Add the male half to some 12-10 gauge wire long enough to go to your work bench and then add a ground clamp to the end of it. Clamp that to your long screwdriver to discharge with, and any voltage would go outside to the earth ground. Here's the female that could be installed in a wall box. http://static.bhphotovideo.com/image...150/718159.jpg And here is the male to add to the ground wire. http://rsk.imageg.net/graphics/produ...160365w345.jpg And here would be the Clamp for the other end.http://lh4.googleusercontent.com/pub...EIq0Nu1ZIBFcc_ I hope I didn't confuse anyone, I tried to keep it simple.

Great idea mechanic, im working on some kind of grounding mechanism. Think that might work.

ummmm. again, I don't think this will work. There is no return path to the capacitors if you short one end to ground. The other end needs to go to ground also. The ground is only connected to electrical devices when the 3rd plug is in the wall. Really, don't over complicate things. Just ground a wire to ground in the TV (bare metal) and run it under the suction cup... That's how they teach it in school.

But, hey, try it out... I don't trust it. But maybe we will get another story out of this?

Goodnight all.

no more "shockin" stories for yall LOL

Electric will head towards an earth ground before anything else. You are just giving it a path of least resistance, being that copper wire is a good conductor. I seen the after effects of a bolt of lightning coming in a power outlet in a guys living room and shooting across the room(thru the couch) and exiting out another power outlet. Sure trashed the electric lines in that house.
That's why lightning will hit a tree, it's well grounded and very wet inside from the sap, and very tall.

The voltage does not stay hidden under the suction cup but in the can capacitors mounted on the circuit board. There is a video on YouTube that shows 4 or 5 can capacitors piggybacked together and supplied with voltage. When they flip a switch the can caps' will smash an aluminum can with the voltage surge, it's cool.

I agree for items plugged in. (Or 30,000 amps from a bolt of lightning). Lightning is static elictricy on a huge level. We are talking about electricity stored in capacitors This item isn't plugged in and ground has been taken out of the circuit. To complete the circuit you need to involve the other side of the capacitance, which is not connected in any way to ground.

That is true also, these caps will hold a charge, but a huge charge is held inside the glass. The entire CRT tube is a huge capacitor and that's where a large shock is hiding.

Really, don't take my word for it. Google this for yourself. There are lots of documets out there. People have been dealing with this ever since the days of black and white. Here's another link for you to consider.

In all actuality, unless these units have been plugged in recently you would have very little to worry about. I would discharge them anyway just to be safe. An ounce of prevention is worth something... something... something.

When I was in the army, I went to class with an individual that was raised by monks that were secretly ninjas. He would sneak over to the rival ninja academy at night to see his girlfriend. I was really disappointed with how poorly ninja's played hacky sack in combat boots.

The moral? Maybe I'm full of it also. You never know. Always verify from several sources before you trust anything on the internet!

I work on stuff on my dining room table. Right outside the window I have a piece of rebar stuck in the ground. I have a wire connected from that to a flathead screwdriver inside. Always double check the connection beforehand. I've never heard that "pop" sound when discharging em though and I've done about 20 TV's. I wear gloves when messing with it even after discharging just incase.

looks to me like the last paragraph supports everything M688 and others have warned us about....and he just kinda glosses over it. (in the site wdaddy recommended above)
