Flybacks and picture tubes are dangerous. Granted.
I remember my fist discharge. Invloved boots, big screwdriver, jumper cables, a sheet of plywood and some glass jars.
Now they involve whatever screwdriver and cliplead is within reach. And sometimes just 2 screwdrivers.
Does anyone actually KNOW about someone being killed working on a monitor and and getting zapped by the tube or flyback?
Sounds like most injuries are typically worse from reactions than electrical shock. IE, banging your head or getting a gash from jerking an arm or head back in response and catching a sharp edge from something.
I have recently caught a couple jolts from some caps that hadn't discharged. Unpleasant but lucky, no burns or whatnot. Can't say the same for the screwdriver I bridged it with afterwards. I could weld with that setup...
Discharged that same cap again on a friends work table with a wire brush and I could TASTE it afterwards.

i asked this question a while back and like you said its the reaction to the shock that causes more injury
when i was a trainee no one told me that monitors kept a charge so i went to pull a anode cap off and i pulled my hand away from the shock and put my hand through the neck thus cutting myself real bad--hospital stitch up job it was

In the days when I used to work on computer VDUs (remember them?) I got many a zap from a final anode and the only (minor) injury was secondary eg bruise or scratch.
Note many people discharge CRTS unnecessarily thus giving themselves an hard time with no reason. There is no need to discharge when handling or moving a monitor. Only need is when the CRT is being disconnected from the main board and the anode cap is being removed.
On old mainframe computers we used to work on live 300 volt DC busbars. That is totally lethal.

In April of 07 I was working on a SanyoEZ in a Donkey Kong table, while it was on, and accidentally hit the high voltage area of the flyback with the small metal flashlight I was holding and was jolted very hard, :badmood: and my right lung collapsed, and I spent 6 days in the hospital with a chest tube, and my mouth tasted like pennies for about that whole time. Ever since then I have used linesman gloves. They are very cheap and could save your life.
Messing around with monitors requires a great deal of precaution and NO DISTRACTIONS
Also, try to avoid working on monitors drunk/high. You are not really concentrating. Youre floating. :dizzy:

What does that mean your lung collapsed? Does it ever go back like it was or it just stays collapsed. How did it feel? Knocked wind out of your chest, did you go to hospital immediately or were you waiting hoping the feeling will go away on it's own?

They have to re-inflate it with a chest tube and catheter.
It actually felt like a little pop, like I cracked a rib or something.
I got some rest and when I woke up I was 'gurgling?' as I took a breath.
Thats when I went to the hospital, and the Xray showed my lung had collapsed.
You ever pull a muscle there on either side of your sternum, that hurts real bad for a week or so when
you breathe? Kinda like that X50. :dunno
