I know its a strange question ??? but has anyone ever heard of a person getting mullered by a monitor,in the early days of slots in the u.k they used a high voltage dc coil on the payout that killed an engineer,also today in england a chap got crushed to death in a 10 pin bowling machine but i have never heard of someone getting it from a monitor.I got a pretty bad h.t belt when i was a trainee(layed on the floor for a couple of minutes and then threw up,oh and had spikey hair for a day or so-but nothing deadly(thats a bit obvious or i would'nt be writing this)
I would just like to state i'm no wierdo or anything :cheers:

Read of at least one instance a year of a toddler pulling on a TV stand and getting killed by a TV.
Not sure if you meant just from a shock by the tube, but if you were just looking for a yes/no answer, then yes someone has been killed by a monitor.

no,i meant due to electric shock

Not sure, it is possible, but I guess you are aiming at the high voltages generated by the flyback transformer. The thing is, of course yes, these voltages are up to 25.000 Volts. However, there is not a lot of real power behind it. Currents are very low.
Luckely, I've never experienced it, but my uncle has repaired TV's for a very long time of his life and occasionaly had (about 2 times) the "pleasure" of touching some wrong part and enjoying that kind of voltage. My uncle is still alive and kicking at almost 60 now.
I've felt the voltage of the backlighting of an Atari Lynx (which is about 1500V) and I tell you, it bites, but that's it... touching both the Live and the 0 wire at once with one thumb at 230V was a hell of a lot less nice experience, I've had two black "contact points" on my thumbs for weeks after that !!!
If you would touch a voltage like that that really has a lot of power behind it (power rails, stuff like that) you're definitly very dead. I've heared a story about two guys working on rails like that and something went wrong. One they never found anything of him back, the other was apparantly able to still take a couple of steps before collapsing. Those steps were marked by small pools of water......what happens is that you became one big blister, all the water is getting out of your body at once.....not a nice thing to think about....
Anyway, electrical stuff is always a combination of both voltage AND current.
There are parts within a TV that carry a (much) lower voltage, but have lots more power (net power f.i. !!) behind it, and those CAN be lethal !
A human body can actualy withstand surprising little current (or is it surprising ?):
AC 1A DC 1A heart stop
AC 75mA DC300mA irreversable heartfibrilation
AC 30mA DC 120mA breathing paralysis
AC 10mA DC40mA Muscle cramps
AC 0.5mA DC2mA gestation
Anyway, better always be safe than sorry....

Hmmmm...... the first time you have it happen to yourself, you may re-think that statement. :laugh2:
I have myself have on a few occasions, and trust me, the kids heard the "crack" from the other side of the house and came in to see what happened.
The world around you comes to a brief stop and you don't even have a chance to say "damn". (comes out more like a grunt)
Possible to survive....most certainly......recommended to try..... no.
But otherwise you are absolutely correct on the point of it being the current that hurts ya, and not the voltage.
Kinda like the difference between a flashlight battery versus a car battery.
You can have similar voltage, but a huge difference in amperage.

Have you heard the one about the guy who was carrying a tube, with the neck against his stomach. He fell and cracked the neck and jammed it in his gut. When they found him his guts had been sucked into the tube because of the vacuum.
-
oh... please make that vision go away.... oh..... ughh
-
I heard another story of a guy getting sucked into a vacuum tube but dont think it was his belly :laugh2:
think it was on one of the dodgy sites my mates looks at :dizzy: :laugh2:

I read about someone dying where I used to work.
He was working on a (live) monitor - he caught a nasty shock of the 24Kv anode; but what killed was the involunatary muscle spasm flicked is arm across to it the 240v ac power source at the inlet; his other hand was holding onto the (grounded) monitor frame. Instant 240V across his chest.
Sadly in the era before RCD's - and to be honest, fuses really are not up to scratch for saving lives...

i wish i had never asked this question,i had a nightmare last night that my brain was sucked out by a living tv tube,now i'm gonna crap myself at work tomorrow-i hope i have no monitor faults,if i die its all your fault :hissy:
