All true I once watched a tv give of a spark that blew out every light bulb in my street, car alarms went off and every tv dinner in my freezer got cooked!!! True story honest.
speakerfreak is ABSOLUTELY CORRECT the crt itself can hold a DEADLY charge. its a vacuum tube and henceforth can store deadly voltages for decades. ask my old friends who found an olddddddd tv by this abandoned farmhouse. the house was abandoned good 40 50 years and this was early to mid 90s but they proceeded to pop crt and they had to run bc a HUGE white bolt came directly at them. thank god for the ditch or theyd prob. be dead now.
@kittyfanatic1980 ...and when the xray builds up, it will become a radioactive critical mass and explode like the Hiroshima bomb.
Absolute dullshit. A CRT can never hold deadly voltage for 50 years (its just static electricity between inside and outside metal paint on the glass; air humidity discharges it at the contact). May be the powder cloud from implosion itself MIGHT produce a lightning, but it sounds unplausible.
The pliars tip was NOT grounded! Which meant YOU ARE the ground, and a milimeter thick of rubber grip is NOT a usefull ammount of HV insulation for a full 30kv. If this was charged, you'd be in a world of hurt right now, NOOB!
well, that dosent look smart. No offence but that could have 20+ kilo volts going through it and easily could have arced up that small pliers of yours
Fortunately, for the man using the pliers, the charge in the tube is relatively low in amps. If you get zapped by it, it won't kill you. However, it will hurt like hell.
Plus, the capacitive charge is parasitic and doesn't remain in the tube for very long; leave it unpowered for a few days or even just a few hours and most, if not all, the charge in the tube will have been lost.
Of course, you should always arc the tube to the DAG ground before detaching the anode cap.
The other thing to observe is that the anode cap on this tube has already been detached. Chances are that whatever charge was in the tube had been discharged when the anode cap had been removed, especially if the anode was ever allowed arc to ground during the removal of the cap.
If that is the case, then sticking the tip of a pair of pliers in the CRT anode would be about as dangerous as white bread toast.
@21hammadmossop yeah very dangerous. I am glad we both agree you can get a shock from the anode hole even after its been discharged. Even if we had to find out the hard way... lol
@21hammadmossop I'm saying from first hand experience. After you discharge the CRT tube it can build a static charge. I know first this first hand. I was working on an arcade cabinet I discharged the anode and pulled it with no problems. Then a few hours later after I got done swapping the board I put the anode back in and got a small static shock. dielectric absorption is what its called. If you don't believe me I encourage you to pull an anode of a crt and come back latter and touch it ;-)
@21hammadmossop same way the tv builds a static charge. the circuit is broken but the tube can still build a static charge. granted its not what it would be if you were barely taking the anode off.
haha funny i just used a sharp blade to cut the cable not knowing it holds power was been used a hour b4 too lol funny shit but id say pig tasers have 50,000 volts correct?
@BeigeNinja You high voltage as well. Also, even 30mA (thirty thousandths of a amp) can kill, with HV. Voltage is needed as well, so it can pierce your skin therefore it can travel around body going to ground. This will result in electrocution.
yea you are correct, but I've seen sparks come out of the TV before, I think it acts like a capacitor and holds a charge. I worked at a TV/computer repair shop for three years. I didn't really do much tv repair, I was the one who fixed the computers. I learned a lot about testing power supplies and circuits though.
yea, It didn't really have that much of a charge on it. And I didn't start recording until after the first time he held the pliers in front of the hole for the anode. You could hear and see a few small discharges if you were there, but the mic or camera didn't pick them up well...

Yah that does nothing, you have to connect it to ground.

the picture tube is a big capacitor, it can zap you!
Moletastic69 1 year ago
It's not the Volts that will kill you. It's the amps. Only .5 amps (not a lot) is enough to kill you.

I thought what held the charge was the anode. (The metal clip inside the rubber cup thats wired to the flyback) Not the tube itself.

Yeh your right, it acts like a glass capacitor

@mcraze123 the tube can hold a charge or even build up a new charge, BE CAREFUL!!!

The anode is inside the tube. The rubber cap connects the flyback transformer to the anode.
redSKORPION50 2 years ago
@anorwood84 The tube itself acts like a capacitor: the flyback is just an ordinary transformer, and has a very wimpy capacitance.
