I think I'll be ok I have AVG installed.

I have mine installed on my flux capacitor.

Talk about patronising. Whats next? Dont make cups of tea because the water is so hot it could scald your skin leaving you scarred for life.

TV's and CRTs are capable of holding a charge of around 30,000 volts thats thirty thousand. You get hit by that its lights out. And the charge in these capacitors has been known to stay in there for up to six months or more.
We have a proper Fully qualified CRT repair technician at college and he wont even touch them unless you hold a gun to his head. He would rather throw them out and buy new.
You could almost say that being a CRT or TV repair technician is not to dissimilar to being a bomb disposal expert. Thats why there are big yellow stickers all over the back of some electrical diposables.

I think is quite a good thread except for a couple of odd comments (and no, I won't go into details).

As for the post about TV screens, yes, they are in effect a large capacitor and they hold a lot of charge even when switched off.

I have had a shock from a TV tube and yes they are extremely painful as well as dangerous (DC current not AC).

There are ways to discharge the current, but not to be recommended for the faint-hearted.

:rotfl:

Your "Fully qualified CRT repair technician" is a lazy wimp then. If he is allowed to throw away perfectly good monitors without even looking at them. Who is paying for this waste? Yes there are high voltages involved but get any risk into perspective, TV engineers have been repairing them for decades and how many have been killed by them. If fully trained he should know what he is doing and use an isolation transformer!

:rolleyes:

Yup he's a lazy wimp :rotfl: :rotfl: :rotfl:

I very much doubt you could be killed by them (unless you were very unlucky or had a very weak heart). Remember volts throw you, amps kill you. When you're just talking about voltage I don't think the human body can even feel any shock below 3000V.

tom you sound like you have just spent a week at an electrical safety course and believed every scare story they threw at you. Crossing the road can kill you...if you are an idiot.

From memory, 30,000 volts sounds right (I'm trying to think back about 10 years!) but the comment about being thrown away is also vaguely true.
I think it comes down to common sense, and how did we get from PSUs to CRTs?

You can get a static shock, say from door on a car, at possibly more than 10,000 V. So giving the voltage as a "danger" is a bit meaningless. It's really down to the amount of energy stored and to be honest, the higher the voltage, the smaller the current, which is the the dangerous component.
